• W852817959 abstract "Milk and dairy products are in short supp1y in rural areas of Zimbabwe. Small holder interest in dairying is increasing. Major constraints are lack of suitable cattle and feed. Indigenous cows are being crossed to Jersey bulls to produce an FI dairy type animal. The calves reached puberty at around nine months and of 26 heifers bulled 23 produced a calf. Milk production, in the first lactation, from the crossbred female was higher in those calving at three years, compared with two years of age (1255v821 I), in excess of rearing their calves). Thirteen heifers were bred for a second lactation and 12 have calved (calving interval 373 days). Male progeny have proved capable as a source of draught power. Slaughter weights of pen-finished steers were satisfactory (227 and 187kg for three and two year olds respectively). Forage is being produced from Pemli,5etum hybrids, but erratic rainfall in 1994-1995 (year of establishment) has delayed full evaluation. INTRODUCTION Milk and dairy products are in short supply in the rural areas of Zimbabwe. Intake of animal protein is low (1). A major constraint to milk production in the semi-arid tropics is lack of feed. In these areas livestock production is usually the preferred activity. Whilst the percentage offtake for beef from small-holder cattle systems is low (2), file reasons farmers give for owning cattle emphasise the importance of draught power, milk production and social security, with beef production being regarded as a terminal function (3). Within the indigenous cattle of Zimbabwe there has been no sustained selection for either milk production or ease of milk let-down. Up to 10 tonnes forage dry matter can be grown with relatively low rainfall « 600mm) using Penni.fetum hybrids (4) .The superiority of indigenous breeds and their crosses as darn lines in these areas has also been demonstrated (5). In another study milk production was similar from crossbred (Friesian or Jersey) Mashona cows (6). When crossbreeding to produce milk in the small holder sector the male progeny must contribute to the overall livestock system. At Matopos Jersey bulls are crossed with indigenous cows to produce FI females with potential for milk production. Penni.'etum hybrids are grown for forage. EXPERIMENTAL PROCEDURES ~ Matopos Research Station lies south of Bulawayo. Rainfall, between November and April, averages 610mm, but amount and distribution are variable. Soils at the tria] site are predominately a sandy clay mixture (7). Animals Since 1991 Nkone and Tuli cows have been bred to a Jersey bull to produce PI progeny. The PI females have also been bred to a Jersey bull to calve for the first time at two or three years of age, from October to December (first groups of PI heifers calved in 1994).
