Comparative analysis of partial suckling and artificial dairy kid rearing systems
(2005) Selejio, O.; Muhikambele, V.R.M.; Ndemanisho, E.E.; Mushi, D.E.
Forty kids aged 1 - 1.5 months and weighing 2.5 - 8 kg were randomly allocated to two: treatments, treatment. 1 (Bucket feeding system, BFS) and treatment 2 (partial suckling system, PSS). One half (10 males, 10 females) was allocated to BFS and the other half to PSS. Breed composition of the experimental animal was 20 kids Norwegian x local crosses and 20 Galla goats. The BFS does were milked twice per day (06: 30 h and 16: 30 h) while PSS does were milked only once per day (16:30 h). Milk yield and surplus (marketable) milk were measured daily for 9 weeks of lactation and kids were weighed weekly during the same period. BFS does produced significantly (P<0.05) higher milk yield (414.96 ± 13.48 g/day) than PSS does (179.23 ± 84.24 g/day. Considering surplus milk, PSS does produced significantly (P<0.05) higher than BFS does which could not even produce enough to feed their kids. The study also showed that crossbred does gave significantly (P<0.01) higher daily milk yield and surplus milk in each treatment compared with Galla does. The kids under PSS had a significantly (P<0.01) better growth rate (42.34 ± 5.46 g/day) than BFS kids (3.92 ± 8.02 g/day) and crossbred kids grew significantly (P<0.05) better (40.09 ± 6.63 g/day) than Galla kids (6.17 ± 7.09g/day). The Gross Margin Analysis (GMA) showed that PSS has a higher gross margin (Shs. 46, 024.9) than BFS (Shs. - 153,825.20). It was concluded that PSS is a better system in terms of surplus (marketable) milk and growth of kids compared with BFS.
Preliminary study on slaughter and meat quality characteristics of selected strains of Tanzania shorthorn Zebu
(Tanzania Journal of Agricultural Sciences, 2021) Mushi, D.E.; Baruani, J.M.
A study was carried out to assess slaughter characteristics and meat quality of five strains of Tanzanian shorthorn zebu (TSZ): Singida white (SW), Gogo (GG), Iringa red (IR), Maasai (MS) and Mbulu (MB). A total of 50 animals (25 entire bulls and 25 castrates) aged 3-4 years were sampled from five slaughter facilities in Tanzania. Slaughter traits, physicochemical properties and the response of beef from the five strains to post-mortem ageing were assessed. IR strain had the highest (P<0.05) values for estimated slaughter weight (ESW), empty body weight (EBW), hot carcass weight (HCW) and linear carcass measurements while MB strain had the lowest values for these parameters. IR strain was 48, 64, 25 kg heavier than MB in terms of ESW, EBW and HCW, respectively. MB strain had the least (P<0.05) proportion of bone in the carcass with about 3% unit less than the rest of the strains. SW strain had the highest (P<0.05) ultimate pH (5.9) while GG had the lowest (5.6). Meat from the GG strain had higher (P<0.05) values for relative redness (15.9) and yellowness (9.8) than that of other strains. Meat from the GG strain had the highest colour stability with only 0.5 units decrease in a* value even after 14 days of ageing. Meat from SW and GG strains became sufficiently tender (<55 N) just after 7 days of ageing whereas that from IR and MB became only moderately tender (55 – 75 N) even after 14 days of ageing. It is concluded that beef from GG strain is the most suitable for processing into high quality meat products owing to its high relative redness (a*), colour stability, tenderness and low pHu.
Public-Private Partnership for Sustainable Production and Marketing of Goat’s Milk in Light of Climate Change

In Tanzania, goat’s milk has a high market value due to its desirable nutritional profile and cultural recognition that it is beneficial to human health. A joint initiative between Sokoine University of Agriculture (SUA) and the Norwegian University of Life Sciences (NMBU) that introduced dairy goats to Tanzania has resulted in approximately 400,000 goats in the region to this day, providing households and communities with milk and various other animal byproducts. In areas such as the highlands of Mgeta in the Morogoro region, where there was previously no production of milk, dairy goats have achieved an average milk production of 1.4 L of milk per animal per day. This led to a rise in milk consumption from 0 L per household per day in 1988 to 1.6 L per household per day in 2012. Although the joint initiative between SUA and the NMBU was suc- cessful in diversifying the diets and improving the livelihoods of the poor, farm group efforts to distribute surplus milk to larger and more distant markets has remained a challenge. Suboptimum feeding practices and low education levels in milk handling and entrepreneurship may explain this lack of progress. In order to expand milk distribution beyond the local market, the involvement of an established dairy company is required. This paper will look at collaborations between farmers, private-milk-processing enterprises such as Shambani Graduates Ltd. (SGL) and a research institution (SUA) to discuss the value of milk in human nutrition and the feasibility of a pro-poor value chain for climate-smart goat’s milk processing and dairy goat maintenance.
