This study was conducted at research farm unit, College of Animal production, Sudan University of Science and Technology from March to May 2016, to evaluate the effect of added graded levels of prebiotics to the diet on performance of Sudan desert sheep. The studied performance parameter were dry matter intake, daily weight gain, final body weight and feed conversion ratio, beside effects on immune system in association with hemoglobin concentration, white blood cell and liver’s enzyme...
ABSTRACT Increased herd productivity and incomes can be obtained with the intensification of smallholder dairy production when applying genetics, ecological and socio-economic interventions. However, intensification can also result in negative externalities including depletion of natural resources, land use changes and human health risks. This study evaluated the association of intensification interventions with herd productivity, natural resource depletion and human health risks using a set ...
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...
This study was carried out to assessment yoghourt produced by camel's milk and cow's milk, From September to November (2014),Camel milk was collected from camel research center University of Khartoum ( Shambat),and cows milk are collected from animal production dairy farm college of agriculture studies, Sudan University of science and Technology (Shambat). Fresh camel and cows milk were analyzed and increased their total solids to 15% by skimmed powder milk to improve the coagulation c...
This study was carried out to evaluate and compare the physicochemical properties of milk samples from three types of animals: cows, goats and camels. The milk samples were collected from 3 animals, (3×3) (Cow, Goats and Camels) individually from East of the Nile, )Khartoum- State) and analyzed for physicochemical properties including: moisture, fat, protein, ash lactose, total solids, pH, total acidity, freezing point, Boiling point, and specific gravity. The results showed that cow�...
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...
ABSTRACT A study was carried out to characterise phenotypically the Ukerewe TSZ strain in order to know if it differs from the Bunda TSZ strain. Respondents from 46 households were interviewed on sources of income and food, number and species of livestock kept, ranking of livestock, usage of cattle, age at first calving, calving interval and lifetime number of calving. A total of 169 adult TSZ cattle were examined for coat colour pattern, and colours of coat, skin, muzzle, eyelid and hoof. ...
ABSTRACT The study was carried out at Fuoni Village in Magharibi ‘B’ District of Zanzibar for period of six weeks, to evaluate the potential of using fish guts in broiler chicken diets. The two hundred and forty broiler chicks were used in four dietary treatments. Each treatment contained 60 chicks which were randomly allocated into four brooding pens and each treatment was replicated 3 times with 20 chicks each. Weight of feeds and refusal were measured daily whereas chick body weight wa...
ABSTRACT Local chicken farmers can improve the performance and quality of indigenous chicken meat by modifying the production systems and age at slaughter. However, in Tanzania there is paucity of information on effect of production systems and age at slaughter of local chicken on growth performance, carcass characteristics and meat quality. The effects of rearing systems, sex and age at slaughter on growth performance, carcass traits, meat tenderness, cooking loss and pH of Tanzanian local c...
