ABSTRACT

Biogas originates from bacteria in the process of biological breakdown of organic material under anaerobic conditions. The demand, high costs and health implications of using energy derived from hydrocarbon compound have necessitated the continuous search for alternative source of energy. Cow dung as a renewable source of energy supply has been proven to be very efficient. This study investigated the production of biogas using cow dung from Nkanu in Enugu East Local Government Area, Enugu state. A 2ml/g of the cow dung was used in this study. The digestion was carried out in a 10 L anaerobic digester at a temperature of 250C to 300 C and uncontrolled pH for a period of 3 weeks. About 23cm3 of biogas was produced on the 22nd day. Thus biogas production from cow dung is a good and cheap alternative source of energy. The use of biogas will not only serve as a source of fuel but will also help in the management of waste. The biomass generated after digestion can be used both as animal feed and to improve soil fertility. It is therefore recommended that large scale production of biogas from wastes should be undertaken by all as the wastes around you today can become your wealth tomorrow.

CHAPTER ONE
INTRODUCTION

1.1 BACKGROUND OF THE STUDY
Fossil fuel provides the bulk of the world’s primary source of energy. Since they are non-renewable natural resources with little to conserve the earth’s supply, supplies of fossil fuel (especially oil and gas) may soon get completely depleted. Additionally, the rising cost of petroleum and allied products most especially in Nigeria has triggered a need to develop alternate sources of energy, one of which is biogas production. In Nigeria, majority of the population are rural dwellers without access to gas or electricity and therefore depend on firewood for cooking and lightening. Unfortunately, this has contributed immensely to the rapid rate of deforestation and desert encroachment. The establishment of biogas plants in these communities would greatly ameliorate these problems and help preserve the environment.
Biogas is distinct from other renewable energy source such as solar energy, wind energy, thermal and hydro sources of energy because of its characteristics of using controlling and collecting organic waste and at the same time producing fertilizer and water for use in agricultural irrigation. Anaerobic digestion process produces a higher biogas yield when running on a mixture of animal manure and vegetable/crop waste rather than animal manure alone, and biogas production is considered the most suitable bio energy technology in china (Wu CZ et al 2009). The slurry and residues from the biogas process can also be used as an organic fertilizer to replace the use of chemical fertilizer on the farm (HUGO 2008; Zhou Cx et al 2004; Liu y et al 2008 and chem. RJ 2007).
The composition of biogas is typically methane (50-70%), carbon-dioxide (30-40%) and the rest is made up of traces of elements of hydrogen sulphide. Biogas can be used in gas engine to convert the energy in the gas into electricity and heat. Biogas is characterized based on its chemical composition and the physical characteristics which result from it. It is primarily a mixture of methane (CH4) and inert carbonic gas (CO2). However the name ‘biogas’ gathers a large variety of gases resulting from specific treatment processes, starting from various organic waste-industries, animals or domestic organic waste etc.

Different sources of production lead to different specific compositions. The presence of H2S or CO2 and water make biogas very corrosive and require the use of adapted materials. The composition of a gas issue from a digester depends on the substrate, of its organic matter load, and the feeding rate of the digester. According to its composition, biogas presents characteristics for comparison with natural gas propane. Biogas is a gas appreciably lighter than air, it produces twice as less calories by combustion with equal volume of natural gas.
The use of fossil fuels as primary energy source has led to global climate change, environmental degradation and human health problems. Also, improper waste management is one of the major problems confronting every development. This is because increase in industrial, commercial, agricultural and environmental activities has resulted in the generation of large quantities of wastes. These wastes, when not properly managed contribute to unhygienic environmental conditions that breed pathogenic microorganisms. Apart from the health implications, wastes make an environment unpleasant and unattractive. However, these wastes can be managed properly by conversion into useful and more environment friendly forms called biogases. Biogas typically refers to a gas produced by the breakdown of organic matter in the absence of oxygen. It is a renewable energy source, like solar and wind energy. Furthermore, biogas can be produced from regionally available raw materials and recycled waste and it is environment friendly and carbon IV oxide (CO2) neutral. Biogas is produced by the anaerobic digestion or fermentation of biodegradable materials such as manure, sewage, municipal waste, green waste, plant material, and crops.

Recently, large volume of cow dung generated from feedlot farming increases annually, most of which are disposed into landfills or are applied to the land without treatment. Anaerobic digestion provides an alternative option for energy recovery and waste treatment. In this paper, cow dung was assessed for the use of anaerobic digestion with the objectives of treating the dung waste to decrease disposal costs and to generate biogas. The biogas produced contains mainly methane and carbon dioxide, and can be used as a source of renewable energy. The aim of this paper was to investigate the effectiveness and the performance characteristics of anaerobic digestion of cow dung for biogas production in batch and semi-continuous operation.

Renewable energy resources appear to be one of the efficient solutions to the problems resulting from the use of fossil fuels. Livestock waste management in many parts of the world is a big challenge which if not properly taken care of can cause a lot of health/environmental problems. Large volumes of cow dung generated from feed lot farming is on the increase, most of which are disposed into landfills or applied to the land without treatment. Animal wastes are abundant all over the world with Nigeria producing about 227,500 tons of fresh waste each day, that 1kg of fresh animal waste produce about 0.03m3 of gas per day. This shows theoretically that Nigeria can produce 6.8 million M3 of biogas daily, which in terms of energy is equivalent to about 3.9 million liters of petroleum. The use of biogas is capable of providing a special impetus in both rural and urban areas. Biogas plant can be built by using materials which are locally available in most developing countries like Nigeria. Nigeria is tremendously blessed with a variety of energy resources (both conventional and non-conventional). The reserves for animal waste alone which is a viable source for biogas production as at 2005 was estimated to be 61.00 million tonnes/yr and crop residue was put at 83.00 million tonnes/yr. However, 50 and 400 MW of electricity is targeted to be generated from biomass by 2015 and 2025 respectively.

Biogas is a renewable, alternative and sustainable form of energy. Not only does biogas technology help to produce an alternative energy source, but it also helps in maintaining the environment and improving health conditions. The energy in plant vegetation, animals, industrial and domestic waste matter can be released in terms of a useful gas when fermented anaerobically, that is, in the absence of oxygen. The biogas formed after the decomposition of organic wastes is channeled or transported to homes for use for cooking, running engines, electrical power generation and heating, with virtually little or no pollution at all. This gas is now used in large scale in many countries. The use of anaerobic digestion as waste-to-energy technology has been employed in the treatment of different organic wastes. This method when used on organic material produces compound like methane, CO2, ammonia, traces of gases, and organic acid of low molecular weight. Ignorance about this technology has made majority of people in the developing countries mainly depend on solid fuel like wood, to meet their cooking and light needs.

Nowadays fossils-based fuel is becoming scarce and more expensive, thus the need to resort to the use of biogas as a more efficient supplement. In this study, biogas production was investigated using cow dung. There was a significant yield of biogas observed in this study.

1.2 STATEMENT OF THE PROBLEM
In Nigeria, the use of wastes from organic matter, though important, has been relegated to the background. There are abundant agricultural residues and municipal solid wastes, whose potentials are yet to be fully tapped for energy generation. The possibility of using such wastes for biogas production should be explored. The raw materials used in commercial methane generation include plant residues, animal waste like cow dung and various urban wastes which are available in Nigeria.

Against this background, this paper appraises insights on environmental and public health implications arising from improper disposal of animal wastes and a comprehensive description of anaerobic digestion of these animal wastes as a means of resolving the ills; with emphasis on types of bio-digesters, microbial communities engaged in the process and techniques for their identification as well as factors affecting the digestion process.
The two enormous problems that are increasingly threatening the good life of many nations include the task of waste management and inadequacy of energy supply. A nation’s inability to dispose waste and to find enough energy greatly affects living conditions. The problem of fuel scarcity and sewage disposal in Nigeria and many developing countries is alarming. Energy generated from waste is therefore needful as it will serve the dual purpose of cleaning the environment and providing a cheaper source of energy. The aim of this research was to investigate the possibility of biogas production from a cheap raw material (cow dung) using a laboratory scale digester.

Without any further argument, the current disposal system for agricultural waste has created a negative effect through disease and pollution problems. The search for alternative sources of energy such as biogas from waste materials like kitchen waste, when increased would help in the elimination and control of deforestation and soil erosion. It should be noted that the development of biogas does not eliminate waste but it makes them easier to manage.

1.3 AIM OF THE STUDY

The importance of biogas as alternative source of energy cannot be over emphasised. It is a sustainable, more environmentally friendly and cheaper source of energy. Henceforth, the researcher want do determine the anaerobic digestion of cow dung for the synthesis of biogas.

1.4 SIGNIFICANCE OF THE STUDY

The most important initial issue when considering the application of anaerobic digestion systems is the feedstock to the process. Almost any organic material can be processed with anaerobic digestion; however, if biogas production is the aim, the level of putrescibility is the key factor in its successful application. The more putrescible (digestible) the material, the higher the gas yields possible from the system.

1.5 DEFINITION OF TERMS

Anaerobic digestion: Anaerobic digestion is a biological process making it possible to degrade organic matter by producing biogas which is a renewable energy source and a sludge used as fertilizer. The production of biogas is carried out in the environment in a natural way (e.g. gas of marshes – vegetable and animal matter decomposition where the formation of bubbles at water surface can be observed).
Anaerobic: life of activity in an airless environment.

Anaerobic Bacteria: microbes whose metabolisms require the absence of free oxygen.
Biogas: a gaseous product of anearobic digestion that primarily consists of methane and carbon dioxide.
Biomethane: This is virtually identical to natural gas, the main difference being that it is produced in days, rather than taking millions of years, billions of years ago.
Digester: the sealed tank or container in which the biological requirements of anaerobic digestion are controlled to hasten digestion and optimize biogas production.
Manure: Animal feces and urine, wasted feed, bedding, and anti-slip material from the barn and yard.

ABSTRACT

The bacterial contaminants associated with commercial poultry feeds from three companies in Nigeria (vital, Guinea and Top) were studied using streak plate techniques. The culture media used were Nutrient agar and Mac Cokey agar. The aim/ objective of the study is: To ascertain the microbial safety of commercial poultry feeds produced by companies. To isolate microorgaisms that are contaminants of poultry feeds, to identify the bacterial types and to determine the microbial load of poultry feed. The microbial mean count was highest in vital feed as 166 per ml with pH 7.80, followed by Guinea feed having mean count of 153 per ml with pH 6-46 and the least microbial mean count was got in Top feed, having 105 per ml withpH 6.00. The study revealed Staphylococcus aureus as the msot predominant bacterial organism with 52cfn (33%) followed by salmonella typhin with 48cfu (30%), The next bacterial organism isolated was Bacillus cereus with 40cfn (25%) and the least was Pseudomonas aeruginosa with 18cfu (12%). Also vital feed had the highest isolation of stapohylococcus aureus, as 60cfu per ml followed by Guinea feed having 57 cfu per ml and least isolation was obtained from top feed as 40cfu per ml. While the highest isolation of salmonella tipphi was obtained also from vital feed as 57cfu per ml, followed by Guinea feed with 50cfu per ml. The highest6 isolation of Bacillus cereus was still from vital feed as 50 cfu per ml, followed by Guinea feed as 43cfu per ml and least in Top feed with 28cfu per ml. The highest isolation of Pseudomonas aeruginosa was from vital feed with 25cfu per ml, followed by Guinea feed with 19cfu per ml while least isolation was from top feed as 10 cfu per ml. The results showed that the poultry feeds in general had bacterial contaminants. But the microbial load was minimal increasing with decrease in acidity (i.e. high pH).

INTRODUCTION
Poultry are collection of birds raised commercially or domestically for meat, egg and feathers. Chickens, ducks turkeys and geese are of primary importance while guinea fowl and squabs (pigeons) are chiefly of local interest. These birds are source of income and food to the rarer. In the past only hens that could no longer produce eggs were killed and sold for meat but by the mid-20th century, meat production had outstripped egg. Production as a specialized industry (Encycloparredia Britaimca, 1988). Heavy breed poultry animals are used for meat white light bread chickens are primarily for the production of eggs (Mc Graw Hill encydopaedia 1992).

The meat and eggs produced from poultry are important sources of dietary portion. In Africa, animal protein foods from all sources contribute between 7g and 15g daily per person to the total food intake (Oyenyga, 1974). Today, Poultry production in the country is increasing at a tremendous rate and yet cannot meet the demand because of population growth and the awareness created by the campaigns for the need of animal protein in the diet.

The growth and well-being of organisms are to a large extent dependent on the mount and type of food they receive and the manner or rate at which they receive it. The food should contain nutrients such as water, carbohydrates, fats, protein, minerals, vitamins and added growth factors improper balance. Each of these nutrients has a major role to play concerning growth, maintenance and productivity of the poultry. According to Leonard 91981), nutritional deficiency or inbalance.

These diseases may include rickets, perosis, and nutritional roup, curly the paralysis etc. These diseases could result due to deficiency in vitamins D, Manganese, vitamin A, vitamin E and riboflavin. Improper sanitation and inadequate management play major roles in disease. Outbreak and productivity of the desired products. In developing countries like Nigeria, the cost of feeding, especially the monogastries continues to escalate primarily in response the soaring cost of the conventional feed ingredients. This phenomenon is precipitated by under production and importation of some food stuff coupled with the competition between man and farm animal for energy and protein concentrates.

The use of agro-industrial by-products towards reducing food cost has been widely recognized (EshieH and Ademosun, 1981; Atteh and Oloagbenla, 1993). Chicken and turkeys satisfy their energy needs provided the ration a allows them to do so (Church, 1988). The are of course exceptional to this rule particularly where heavy breed layers are concerned, when birds have a tendency to over-eat. Where this is a problem, it is general practice to subject the birds to some degree of food restriction during the growing and production periods.

The major ingredients that are integral parts of poultry rations at the present time in the USA are corn, as the primary source of energy and soybean meal as the major protein supplement (Roland et al 1972), while in Nigeria, Udedibie et al (1988) and Nwokon (1993) produced poultry offal meal (P.O.M) and chicken offal meal (COM) respectively from waste product similar to poultry visceral Offal (PVO) according to these authors POM has been used to replace ground nut cake in layer and broiler finisher diets and COM has been used along with fish meat and blood meat as sources of methodize and lysine in the starter diets of lockerels. These major ingredients, usually available in plentiful supply, allow rapid growth or high egg production with very efficient conversion.

However, corn-soy rations are deficient in some nutrients for chickens and these nutrients are normally supplied by other poultry meal.
There are different types of feeds given to poultry brids depending on the purpose. These different types of feeds given to poultry birds depending on the purpose. These different types are the breeders’ starters, growers’ and layer’ feeds. The percentage of each ingredient in the feed varies depending on the type of feed. The ingredient include ground yellow corn, ground oats or barley, Alfata meat, Fish meal, Oystershell, managised salt, vitamin A, vitamin D, and coccidiostat (which is given in form and at the level recommended by the manufacturer).

The different percentage of each ingredient varies depending on the kind of feed for example, ground yellow corn in starter and grower feed is 25% and 22% in breeder and layer feeds. There could be the same percentage of a particular ingredient in different feeds as in the case of a alfafa meal which constitutes 10% inall the feed types. Some ingredients could be absent in a particular feed but present in the others as in the case of riboflavin supplement which is absent in starter feed and present at the levels of 2 and 5% in rower, layer and breeder feeds respectively.

To maintain healthy birds, the feeds are kept fresh as much as possible at all times. The amount of feed in feeders are limited to the extent necessary to avoid wastage. It is a good practice to fill hanging feeders – only three quarter full, and trough feeders only two third full (Graham, 1977). Checking the weight of the birds and its feed consumption is very necessary. A drop in feed intake usually is the first indication of trouble, a disease outbreak, molt, stress or poor management (Graham, 1977).

Most poultry feed are prepared in dehydrated forms and because of this, there is the need to store them properly to avoid moisture uptake and damage by heat. In this way,. They can remain safe for a considerable period of time without loosing their safeness and value. The feed should be stored in a suitable place where it will not be attacked by microorganisms, insects, rodents, etc. Air tight storage is not advisable because offensive odour might result when there is obstruction of out flow and inflow of air (Leonard, 1981). High temperature and oxidation destroy certain vitamins, therefore, care must be taken in the preservation and storage of feeds to protect the vitamins they contain (Mc Graw – Hill encyclopaedia 1992).

The condition of feed storage and handling could be a source of contamination. When feeds are unhysgenically handled and stored, there could be a buildup of microbial contaminants.
Poultry have been found to be susceptible to infection due to certain microorganisms and man may be secondarily infected through heavy contaminated food such as poultry meat and eggs (Gorden and Tucker, 1965, Hall, 1977, and Barrell, 1982). Micro-organism that may contaminate feed include the following general another disease caused by salmonella infections is paratyphoid. Paratyphoid is an infection disease of chi, Entherobacter, Escherichia, Protens, Pseudomonas, staphylococcus, salmonella, shigella, providencia, serratia, Klebsiella, streptococcus, clostridium, Aspergillus and Erysiphelothrie (Leonard, 1981). Typically, in some countries, about 50% of all outbreaks of salmonellosis in man are caused by infections derived from these sources and the incidence of salmonella in poultry carcasses has, in certain cases been found to be 7% or more (Van schothorst Notermans, 1980). Okongi (1984) examined poultry feed and found that salmonella was present in the sample. Another disease caused by salmonella infections is paratyphoid, Paratyphoid is an infections disease of chicken, turkeys, ducks and…

INTRODUCTION
1.1 HISTORICAL BACK GROUND
Antibiotics are chemicals when the chemical are put into the body, they stop the growth of kinds of germs. They help the body to fight diseases. More than 3,000 years ago ancient people stumbled over the discovery that some moulds could be used as a cure. The egyptians, the chinese, and indians of central American would use mold to treat rashes and infected would. At that time they didn’t understand either diseases or treatment. As time went on, people began to gain some insight of disease. In the 1860 Louis Pasteur Shaw that many disease were caused it bacteria. Later he discovered that we may be able to fight germ and other microbes. It was two German doctors, who were first to make an effective medication form microbes. Kudo if and Emmerich and Oscar has conducted their experiment in the 1890. They proved that germ that would for another. All the men did was to take the germ from infected bandages and grow then in a test tube. They would then isolate a particular germ that caused green in factions in open would. This germs was bacteria called Bacillus pyoicyaneus. They put then into another test tube containing other type of bacteria, it was then it happened that the bacillus pyocyaneus wiped out the other disease germ. The germs that was killed were those that caused cholera, typhoid, diphtheria and anthrau. From this the two men created a medication that they called pyoanase, it was the first antibiotics used in hospitals.

In 1928 Alexander Fleming, a Scottish scientist, discovered penicillin, the first antibiotics. He was keeping in a petn dish when a speck of mold fell in, it cause the mold to grow on the nutrient agar used to feed the bacteria. Surpassingly, it stopped the growth of the bacteria. Fleming through the mold called penicillin notatum produced a substance that killed the bacteria and so called it penicillin. However, he was not able to entrant it from..

CHAPTER ONE

1.0 INTRODUCTION
Spoilage is a relative term. The presence of microorganisms in food does not necessarily indicate spoilage neither is the presence of pathogenic organisms means that the food is spoilt.
Spoilage refers to decay or decomposition of the food that results in an undesirable nature of the food in taste, texture, odour and appearance. It is sometimes difficult to differentiate between spoilage by microorganisms and harmless growth or the same type of change may be considered disable, in another. For instance, the beneficial aspects of bacteria, yeast and moulds can be noted in the production of compost, wine, garri, ogi and some antibiotics.

A person may consider sour milk spoilt, but the cultured yogurt or cheese made by the same lactic acid fermentation good. Therefore, fermentation may seemly indicate spoilage but production from the fermentation of milk like yogurt, cheese shows that spoilage is a relative term.

Thus, some changes termed spoilage may be only changes in appearance or physical characteristics, although the product has undergone no microbial spoilage and there has been little loss in nutritive value. Hence, each consumer has his own idea about whether a food is spoilt or not, and normally can come to a decision about its edibility without much difficulty based upon his sense of sight, small, taste and touch as well as his past experiences on the evaluation of the quality of the food.
Having seen what spoilage refers to, it will be easy for us to look at the various ways which microbial food spoilage can be caused and consequently controlled.
