Seasonal breeding is potentially a powerful intervention affecting productivily, particularly so in semi-arid environments where seasonal differences are great; however, variability is also great, increasing the risk for such interventions. Simulation was used to examine the effects of 5 breeding...

Blended goats are a 3-way cross of meat goats, between Boer x Kamorai x Small East African goats; they constitute less than 5% or the 6 million goat population in Tanzania. Goats in the project were raised mainly on pastures with similar supplementation or concentrates at Kongwa and Malya station...

There are various methods of measuring milk yield from goats. In the present study 84 lactating Galla goats on a Rhodes grass (Chloris gayana) hay basal diet and supplemented with 500g (as is) of a concentrate diet constituting of poultry litter (0, 15, 30 or 45%) were used to compare milk yield ...

Records on liveweight, growth and reproductive performance of Blended (BLD), Blended x Galla (BG) and Kamorai x indigenous (KI) goats for a period of over 10 years (1970-1980) in Malya, Tanzania were analysed. For BLD, BG and KI goat kids, birth weight and live weight averages were determined. Se...

Goat production in Swaziland is characterized by low offtake resulting from lack of management of rangelands and seasonal fluctuations in feed resources. Periodic droughts and extensive dry spells in winter which cause nutritional stress result in low productivity of the goats. The aim of the stu...

A total of 587 kidding records of the West African Dwarf (WAD) goats over a period of 10 years (1982-91) were used for this study. The mean kidding interval and litter size at birth were 275.68±6.08 days and 1.79±0.05 kids, respectively. Effect of parity, season and year of birth were significant...

Oestrus was synchronised with PGF2-alpha in four pluriparous West African Dwarf (WAD) goats and blood collected through jugular venupuncture. The length of the oestrous cycle and oestrus duration were observed in three successive cycles while peripheral plasma progesterone and oestradiol-17B leve...

A herd of small East African (SEA) (or Maasai) goats and Galla (Long-eared Somali) immatures were used for this study at the Olturot substation of NALRC. The goats were ear-eagged and milk records were taken once a week using the system established by UNESCO-IPAL the predecessors of NALRC. Birth ...
