Controversy has surrounded the possible differences in pasture production which result from grazing by cattle or sheep. Experiments conducted over the 1972-76 period show that pasture production under grazing by sheep is greater than under grazing by cattle under similar intensive managements. A change from sheep grazing to cattle grazing can cause a rapid deterioration in pasture production, w...

Identification of breeding objective traits pertinent to specific production environments with the involvement of target beneficiaries is crucial to the success of a breed improvement program. A choice experiment was conducted in four locations representing different production systems and agro-ecologies that are habitat to four indigenous sheep breeds (Afar, Bonga, Horro and Menz) of Ethiopia ...

The enantioselective sulfoxidation of the prochiral anthelmintic compounds albendazole (ABZ) and fenbendazole (FBZ) was investigated in liver, lung and small intestinal microsomes obtained from healthy sheep and cattle. The microsomal fractions were incubated with a 40 microM concentration of either ABZ or FBZ. Inhibition of the flavin-containing monooxygenase (FMO) system was carried out by pr...

This paper reviews current production trends for sheep and beef cattle production in New Zealand and gives some insight into the opportunities for improvement. The New Zealand climate favours pasture growth and this is the key to sheep and beef cattle production with over 95% of the diet being grazed pasture or crop. Exports are the focus of the industry with 92% of sheep meat and 82% of beef e...

I . Sixteen experiments were made with eight sheep to determine the effects of various compounds on methane production, digestion and metabolism. 2. Two experiments with two sheep given stearic acid incorporated in the diet showed that it depressed CH, production by 2.7 moles/mole stearic acid. The digestion of the basal diet was also depressed, the apparent digestibility of dietary cellulose f...

1. Choline production by various tissues of the sheep was measured by determining venous and arterial free choline concentrations in blood samples taken from various vessels in conscious multicannulated sheep. 2. Significant production of free choline occurred in the upper and lower body regions, and specifically in the heart, brain and hind-limb muscles of sheep, but there was no significant u...

Transhumance is an extensive farming system developed by livestock farmers, that moved their herds between lowlands and uplands, in order to cope with the seasonality of the available forage. The purpose of this study was to examine the transhumant sheep and goat system in Greece highlighting differences in management aspects among the country’s regions. Non-parametric statistical methods in a ...

Diseases of the lower respiratory tract of sheep are not considered a serious cause of lost productivity in Australian flocks because of the generally sporadic nature of serious respiratory disease and the sub-clinical nature of most cases of respiratory infection. The extensive conditions under which Australian sheep are usually managed do not favour transmission of pneumonic infectious agents...
