Zerbini, E.Gemeda, T.Tegegne, AzageGebre-Wold, A.Franceschini, R.[Effects of work and diet on progesterone secretion, short luteal phases and ovulations without estrus in postpartum F1 crossbred dairy cows]Effects of work and diet on progesterone secretion, short luteal phases and ovulations without estrus in postpartum F1 crossbred dairy cows

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...


Gemeda, T.Zerbini, E.Gebre-Wold, A.Demissie, D.[Effect of draught work on performance and metabolism of crossbred cows. 1. Effect of work and diet on body-weight change, body condition, lactation and productivity]Effect of draught work on performance and metabolism of crossbred cows. 1. Effect of work and diet on body-weight change, body condition, lactation and productivity

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...


Zerbini, E.Gemeda, T.Franceschini, R.Sherington, J.Gebre-Wold, A.[Reproductive performance of F1 crossbred dairy cows used for draught: Effect of work and diet supplementation]Reproductive performance of F1 crossbred dairy cows used for draught: Effect of work and diet supplementation

Forty pregnant F1 crossbred dairy cows (20 Friesian x Boran and 20 Simmental x Boran) were stratified in a 2 x 2 Diet x Work factorial experiment (not working, not supplemented; not working, supplemented; working, not supplemented; and working, supplemented). Working cows pulled sledges 100 days/...

Twelve non-milking, non-cycling F1 crossbred dairy cows (Friesian x Boran and Simmental x Boran) in low body weight and body condition were stratified to 2 diets according to parity, body weight, body condition score and calving intervals to estimate time necessary to resume reproductive activity...


Zerbini, E.Gebre-Wold, A.Gemeda, T.Demissie, D.[Effect of supplementation of depleted, non-milking, non-cycling F1 crossbred cows on time of repletion and resumption of reproductive activity]Effect of supplementation of depleted, non-milking, non-cycling F1 crossbred cows on time of repletion and resumption of reproductive activity

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...

Forty F1 crossbred dairy cows (20 Friesian X Boran and 20 Simmental X Boran) in a 2x2 factorial arrangement (not working-not supplemented, NWNS, not working-supplemented, NWS, working-not supplemented, WNS and working-supplemented, WS) were used to study the effect of work and diet supplementatio...


Zerbini, E.Gemeda, T.Gebre-Wold, A.Nokoe, S.Demissie, D.[Effect of draught work on performance and metabolism of crossbred cows. 2. Effect of work on roughage intake, digestion, digesta kinetics and plasma metabolites]Effect of draught work on performance and metabolism of crossbred cows. 2. Effect of work on roughage intake, digestion, digesta kinetics and plasma metabolites

Forty F1 crossbred dairy cows, 20 Friesian x Boran and 20 Simmental x Boran, in a 2 x 2 factorial arrangement (non working-non supplemented, non working-supplemented, working-non supplemented, and working-supplemented) were used to study the effect of work and diet supplementation on roughage int...


Zerbini, E.Gemeda, T.Gebre-Wold, A.Demissie, D.[Effect of work and diet on dry matter intake, feed digestibility and nitrogen balance of F1 crossbred cows used for draught]Effect of work and diet on dry matter intake, feed digestibility and nitrogen balance of F1 crossbred cows used for draught

The results of the research showed that hay intake was 10 percent greater in working compared to non working cows. Cows responded to underfeeding by a progressive adaptation until a new equilibrium between dietary supply and requirements was reached. However, in draught cows fed low quality rough...


Zerbini, E.Gemeda, T.[Effect of work on dry matter intake, milk production and reproduction of multipurpose cows fed low quality roughage]Effect of work on dry matter intake, milk production and reproduction of multipurpose cows fed low quality roughage
