Abstract: This dissertation is composed of three separate experiments. The first and second studies evaluated the performance of broilers and white leghorn layers fed different levels of enset corm replacing maize grain. The third experiment assessed the performance of white leghorn layers fed kocho diets replacing maize. In the studies with enset corm treatments were ration consisting 0 (T1), 15 (T2), 30 (T), and 45% (T4) of enset corm as a replacement for maize by weight. In the experiment...
Abstract This study aims to investigate the phenotypic and genotypic characterization of Fuga cattle in North Kordufan. A set of detailed structured questionnaires were used to collect information from Fuga cattle owners (150) .The questionnaires were pre-tested to check clarity and appropriateness of the questions. Some of the informations collected during interviews were supported by observations on milk yield per day, milk yield per lactations ,lactation length , age at first calving...
Abstract The indigenous chickens are known of low productivity and adaptability to their local environment which made them to be resistant to some extend to some diseases prevalent in their localities more than exotic breeds. In this study two experiments were conducted. The trial was concerning phenotypic trial of indigenous Bare neck chicken. The second experiment was handling three genesin order to show polymorphism in the three genes GH, PIT1 and PRLR. In the first trial phonetic p...
ABSTRACT An experiment was conducted to determine the effect of re-mating interval on the reproductive efficiency of rabbits (doe). The experiment was designed to test two re-mating intervals - 14 and 21 days interval to determine the most suitable for the following traits body weight changes during pregnancy, litter weight, litter size, still birth, body weight before weaning, weaning weight and body weight after weaning. Twenty-five (25) matured does and five (5) matured bucks of different...
ABSTRACT This study was conducted in two divisions namely Namanyere and Mkwamba of Nkasi district in Rukwa region in order to assess sheep production status for smallholder farmers. Eight wards namely Namanyere, Mtenga, Chala, Swaila, Kipande, Sintali, Kate and Isale were surveyed from November 2010 to April 2011. The random sampling technique was adopted to get 20 respondents from each of the selected wards. This means two villages from each ward were chosen randomly whereby in each villag...
ABSTRACT This study consisted of two experiments, (i) Assessment of pasture composition and productivity during dry season, (ii) Assessment of the response of communal grazing land to selected rangeland improvement practices (oversowing, manure application and furrows for rain water spreading) on pasture composition and productivity was conducted at Lubungo village in Mvomero district, Morogoro Tanzania. In study one, data of vegetation ground cover, dry matter yield of pasture and tree dens...
ABSTRACT A study was conducted to evaluate the effect of three mixed rations formulated using locally available feed resources on growth performance, carcass characteristic and the potential revenue returns from goats fattening enterprise in Zanzibar. Seventy-two un-castrated local goats (9 – 12 months old) with an initial body weight of 14.24 ± 1.39 to 14.59 ± 3.7 kg were divided into three groups of 24 animals each and were randomly allocated into three dietary treatments (D1, D2 and D...
ABSTRACT A study was conducted to evaluate the growth and carcass performance of sheep under two feedlot finishing diets in Zanzibar. Fifty four sheep (age of 9-12 months with initial body weight 18.9±0.6kg) were divided into three groups (T1, T2 and T3) of 18 in 3 replicates (each having 6 individuals). The sheep in T2 and T3 were assigned randomly to two concentrate formulations (Concentrate 1 and Concentrate 2) and a third group of similar number used as a control (T1) was grazed during...
ABSTRACT This study was carried out to evaluate the current performance of dairy cattle at ASAS and Kitulo farms in the Southern Highlands of Tanzania. The objective was to assess the effects of genetic and non-genetic factors on lactation and reproductive performance, calf mortality rate, longevity traits and constraints affecting performance of dairy animals. Ayrshire and Friesian cows were involved in the study. Data were analysed using General Linear Models procedure of Statistical Analy...
ABSTRACT The effect of breed and different oil seed cake supplementation on milk yield, composition and milk fat fatty acid (MFFA) composition was studied using 12 Friesian and 12 Ayrshire lactating cows. Control diet contained maize bran (MB) plus minerals. For diet I and II, some of the MB in the control diet was replaced with cotton seed cake (CSC) (34.8%) and sun flower seed cake (SSC) (44.5%) respectively. Milk samples were collected for chemical composition analysis and butter making. ...
ABSTRACT The study was conducted to assess the effects of Effective Microorganisms (EM) as feed additive in broiler chicken production on growth performance, health and foul smell control in poultry house. The experiment involved two hundred and ten, day old hybro broiler chicks which were randomly allocated to 14 pens each with 15 birds in seven treatments with two replicates. The main treatment (EM) was provided to experimental birds in two levels: 10mlEM2/l and 20mlEM2/l either in drinkin...
EXTENDED ABSTRACT Raising chickens is rapidly gaining popularity in the developing world. However, high feed costs associated with intensive poultry rearing as well as increased competition between humans and animals/chicken on feed demand have necessitated the need for exploring new options in chicken feeding. Furthermore, chickens have a limited foraging range a factor that translates in a very narrow array of feeds they can access. Sorghum is one such feedstuff which is widely grown in Ta...
ABSTRACT A study was carried out in Magu and Ilemela districts in Mwanza region to characterize cattle finishing systems and identify the factors limiting cattle growth performance. A total of 120 agro pastoralists and 30 cattle finishing entrepreneurs were interviewed using questionnaires. Seven focus group discussions were also performed. In addition, monitoring study on cattle growth performance was done for 56 days on a total of 105 cattle, of which body weight gain of cattle was measure...
ABSTRACT The assessment of technology adoption for free range local chicken improvement was carried out using a sample of one hundred and twenty (120) farmers, fifty trained farmers, fifty neighbouring farmers and twenty control farmers. A structured questionnaire was used. Other data were obtained by direct measurement of eggs and adult live birds. Multiple Range Test (MRT) was used to separate the means especially for the production data. Results indicated that adoption rate among the trai...
EXTENDED ABSTRACT Growth performance and productivity of Nile tilapia (Oreochromis niloticus) is highly influenced by water quality in the pond. On the other hand, water quality is influenced by the climate and ecological conditions of the place. This study evaluated the growthperformance, survival rate, yield, body length-weight relationship and condition factor of Nile tilapia (Oreochromis niloticus) cultured in two districts; Mbarali and Mufindiof Mbeya and Iringa regions,respectively. Fu...
