Journal Article 1999

Autor: Zerbini, E. Gebre-Wold, A.

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...

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...

This study examined whether a prolonged anoestrus had any long-term effect on subsequent fertility of cows and estimated the relationship between repletion and resumption of reproductive activity. Twelve low body-condition, non-milking, non-cycling (depletion state) F1 crossbred dairy cows (Fries...

Cardio-respiratory and mechanical work output variables were measured for four F1 crossbred dairy cows (average weight 475 kg) over a range of work levels. Resting (standing prior to exercise) heart rates (average 62 beats per min) and respiratory rates (average 21 breaths per min) were similar t...
