This study was undertaken to investigate the relationship between date of birth and growth performance of calves born to seasonally-bred range cows. Late born calves exhibited an apparent superiority in preweaning growth over that of their early-born counterparts. This was attributed to a positiv...

The paper evaluates the effects of forage type and level of concentrate supplementation on forage intake, diet apparent digestibility, purine excretion and milk production. Twelve crossbred cows (Bos taurus X Bos indicus), in early lactation were allocated to the following six dietary treatments:...

A feeding system, draught cows, disease/work interactions and animal power introduction in a farming system are reviewed. A new feeding system for draught animals is described which enables feed requirements and the effects of work on liveweight and milk yield to be calculated. Recent data on the...
Two experiments with 12 and 18 lactating Jersey cows respectively were carried out in the coastal semi-humid zone of Kenya to assess the performance arising from the feeding of chopped Napier fodder (Pennisetum purpureum) given ad libitum with and without one of three sources of protein; fishmeal...

A study was conducted at the Asella Station in the Arsi Region of Ethiopia to investigate the dairy performance of indigenous purebred Arsi and Friesian X Arsi crosses under different pre-partum and post-partum supplementary feeding regimes. A total of 343 first-lactation animals were involved in...

The season of calving affected calving interval, weaner weight per cow per year, dam weights at mating, parturition and weaning, and dam weight changes during gestation and lactation. The year of calving influenced calving interval, calf survival, weaner weight per 100 kg of cow weight per year, ...

Four rumen and duodenal cannulated lactating cows were fed grass silage based diets supplemented with either barley (B), or barley and beet molasses (M), or barley and wood molasses (W) or barley and beet pulp (BP) in a 4x4 latin square design. Dry matter consumption was 15 kg day and roughages c...
