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...

Multi-purpose cows for milk, meat and traction in smallholder farming systems. Proceedings of a consultation

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 ...

Forty pregnant F1 crossbred dairy cows (20 Friesian X Boran and 20 Simmental X Boran) were stratified in a 2x2 diet X work factorial experiment (not working-not supplemented, NWNS; not working-supplemented, NWS; working-not supplemented, WNS; and working-supplemented, WS). Working cows pulled sle...

Effect of work and diet on body-weight change, body condition, lactation and productivity

Eighteen F1 crossbred dairy cows (Friesian X Boran and Simmental X Boran) were allocated to one of three diet groups (H: natural pasture hay; H + 3: natural pasture hay + 3 kg concentrate; and H + 5: natural pasture hay + 5 kg concentrate) using a stratified random sampling procedure, with parity...

Forty pregnant crossbred cows (20 Holstein-Friesian X Boran and 20 Simmental X Boran) were assigned to a 2x2 (work X diet) factorial experiment as follows: supplemented-non-working (SNW), supplemented-working (SW), non-supplemented-non-working (NSNW) and non-supplemented-working (NSW). Working co...
