This study examined whether work applied at different stages of lactation had any effect on reproduction of cows under two feeding regimes. Twenty-four F1 crossbred dairy cows (12 Friesian X Boran and 12 Simmental X Boran) were allocated one of two diets (H + 3: natural pasture hay + 3 kg concent...

Journal Article 1999

Autor: Pearson, R.A. Zerbini, E. Lawrence, P.R.

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...

Post-partum reproductive function of 50 F1 crossbred (Boran X Friesian) cows under smallholder farms around Holetta were monitored using plasma progesterone concentrations and profiles to examine Ovarian activity of cows and accuracy of estrus detection. Experimental cows were observed for signs ...
