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

The aim of this consultation is to explore the practicality of extending technologies that enable the use of dairy cows for multiple purposes, to help develop a regional project to transfer these technologies to relevant countries in east and Central Africa. The focus of the consultation is on ne...


Zerbini, E.Shapiro, Barry I.Chirgwin, J.C.[Technology transfer. Multi-purpose cows for milk, meat and traction in smallholder farming systems. Proceedings of a consultation]Technology transfer. Multi-purpose cows for milk, meat and traction in smallholder farming systems. Proceedings of a consultation
Autor: Zerbini, E.

The principal objective of the workshop was to develop a funding proposal to implement transfer of the IAR/ILRI multi-purpose crossbred cows technologies to eastern African smallholders. The workshop proposed a formal means of co-ordinating and linkage and transfer mechanisms needed to ensure the...


Zerbini, E.[Objectives of the expert consultation]Objectives of the expert consultation

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...

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

Production performance of cows is an important factor which determines whether cows are adopted for draft power. Working cows could perform at higher levels of efficiency than oxen, but only if nutrient inputs are adequate to meet their greater requirements, and milk production and reproduction a...
