On – Farm Evaluation Of Performance Of Sukuma And Malya Goats And Their Crosses In Maswa District, Tanzania

ABSTRACTGoat production is an integral component of small holder agriculture in Tanzania but farmers have been keeping indigenous goats which have poor genetic potential for growth and have small mature body size. Goat keepers can improve mature body size by crossing with improved breeds. However, in Tanzania there is paucity of information on performance of crossbreds in comparison to their parents. The effects of breed, sex, birth type, season of birth, year of birth and dam weight class on...

Evaluation Of Seaweeds As Mineral Source In Broiler Diets

ABSTRACTAn experiment was conducted at the Poultry unit of Kizimbani Agriculture Training Institute in Zanzibar to evaluate the effect of seaweed as mineral source in the growth performance of broiler chickens and carcass characteristics. Two hundred and forty (240) broiler chickens were fed four dietary treatments (T1, T2, T3 and T4), containing 0, 1, 1.5 and 2% seaweeds, from 8 - 49 days of age. Feed intake was measured daily while live weight was measured on a weekly basis. After seven wee...

Evaluation Of Microbial Contamination Along The Milk Value Chain In Two Districts Of Tanzania

ABSTRACTMilk is important as a valuable diet, but due to its nutritional value and perishable product it serves as an ideal medium for growth of various microorganisms under suitable conditions, hence it is a staple food in epidemiology linked to zoonotic pathogens. This study was carried out in two districts in Tanga region (Northern Tanzania) to estimate microbial load, isolate selected pathogens and establish their possible sources or entry along the milk value chain. A total of 114 respon...

Yield forage samples were collected using 0.25m2 metal quadrat after which chemical composition, dry matter yield (DMY) and in vitro dry matter digestibility (INVDMD) were analyzed. Line Interception Method was used to estimate forage species distribution. Woody ...

Growth Performance And Carcass Quality Of Broiler \ Chickens As Influenced By Proprietary Source Of Feed

ABSTRACTThis study investigated the quality of selected popular poultry feeds available in Nigerian poultry feed market, using growth performance and carcass quality of broiler chickens as indices. Day old broiler chicks were fed with diets obtained from four different commercial feed manufacturers (coded FTE,GFE,PFE and SFE to protect the manufacturers) and control diet (formulated in conformity with recommended nutrient requirements for broiler chickens) over an eight week trial period .

Microbial Load, Cholesterol Levels And Sensory Quality Of Hard-Boiled Commercial Eggs

ABSTRACTMicrobial flora and load, Cholesterol levels and sensory quality of attributes of hard-boiled commercial eggs being hawked along Lagos-Horm Road were monitored in this study. The bacteria isolated from the eggs include; Achromobacter sp. and Staphylococcous aureus. While the eggs sampled from Ibadan, Ogbomoso and Ilorin had lower microbial load (20 - 33 X 104 CFU/g). On the average a 56g egg was found to contain 235mg Cholesterol. The results of sensory quality evaluation showed ...

Effect of dietary alternative lipid sources on haematological parameters and serum constituents of Heterobranchus longifilis fingerlings

Abstract The worldwide increase in aquaculture production and the decrease of wild fish stocks has made the replacement of fish oil (FO) in aquafeed industry a priority. Therefore, the use of terrestrial animal fats and vegetable oils, which has lower cost and larger supplies, may be good as substitute for FO. This study investigate the effects of total replacement of FO by two terrestrial animal fats (pork lard and poultry fat) and three vegetable oils (palm kernel oil, shea butter oil and s...

Effects of dietary lipid source on growth, digestibility and tissue fatty acid composition of Heterobranchus longifilis fingerlings

AbstractOne of the major problems facing aquaculture is the inadequate supply of fish oil mostly used for fish feed man- ufacturing. The continued growth in aquaculture production cannot depend on this finite feed resources, therefore, it is imperative that cheap and readily available substitutes that do not compromise fish growth and fillet quality be found. To achieve this, a 12-week feeding trial with Heterobranchus longifilis fed diets differing in lipid source was conducted. Diets were s...

The Use of Cassava, Sweet Potato and Cocoyam, and Their By-Products by Non – Ruminants

Abstract As the search for alternative sources of energy for non ruminants continues, this review was undertaken to examine the potential value of cassava (Manihot utilissima Pohl.), sweet potato (Ipomea batatas Poir.), cocoyam (Xanthosoma sagittifolium Schott.) and their by-products as dietary supplements for non ruminants. Studies on these roots and tubers showed that, on a dry-weight basis, contained 2.0 – 7.9% crude protein, 0.3 – 3.1% crude fibre and 72.4 – 77.9% starch. The practi...

Risk and benefits of human consumption of raw and pasteurized cow's milk

ABSTRACTIn the context of the prevailing trend towards more natural products, there seems to be an increasing preference for raw milk consumption as raw milk is associated with several perceived health benefits that are believed to be destroyed upon heating. However, many human pathogens can be isolated from raw cow’s milk and these pathogens vary from campylobacter to Escherichia coli. The aim of this review is to highlight the risk and benefits related to the consumption of raw and pasteu...

THE RELATIONSHIP BETWEEN BODY WEIGHT AND LINEAR BODY MEASUREMENTS IN BUNAJI CALVES AT DIFFERENT PHASES OF GROWTH
