Data collected at the livestock research centres, Malya and West Kilimanjaro, Tanzania, to determine the effects of genotype and environment on birth weight, weaning weight and weight at 24, 48, and 72 weeks of age were analysed. Records on the birth weight (n = 6207), weaning weight (n = 4444), ...

Growth and reproduction performance of Blackhead Persian sheep in Tanzania
A 148 days study was conducted at Morogoro to evaluate the mineral status of Blackhead Persian (BHP) lambs and their response to mineral supplementation under grazing conditions. Soil, forages and blood plasma were analysed monthly for Ca, Mg, P, K, Na, Cu, Fe and Zn. Also pH in soil and CP in fo...

A study was conducted to investigate the effect of inclusion of Lablab meal on growth rate, feed intake and carcass composition of Black Head Persian (BHP) lambs. Twenty-four BHP castrate sheep with average weight of 14.1 +2.7 kg were allotted randomly to four dietary treatments. Lambs were indiv...

Lablab (Dolichos lablab) meal as protein supplement for weaned fattening lambs
Limiting factors in sheep production in Tanzania are discussed. Due to lack of quantitative data effects of diseases and other factors, the paper partly attempts to quantify the performance of two breeds of sheep (Black Head Persian-BHP and Red Maasai-RM) under one government farm. Statistical co...

Growth and digestibility studies were conducted with grazing indigenous Tanzanian goats on different levels of supplementation of Leucaena leucocephala. Four treatments were hay only (H), hay and 100 g leucaena (HL1), hay and 200 g leucaena (HL2) and hay plus leucaena ad libitum (HL3) in the grow...

Twenty-four growing indigenous Tanzanian male goats were studied in a completely randomized design experiment with four treatment groups for growth rate, feed conversion ratio (FCR), dressing percentage and carcass composition. The four groups of goats were fed hay ad libitum (A) and hay ad libit...
