Abstract

In pasture-based, seasonally calving dairy herds of southern Australia, the mating period usually consists of an initial artificial insemination period followed by a period of natural service using herd bulls. The primary objective of this study was to identify associations between individual bull- ...

Abstract

Two studies were conducted to assess the performance of a commercially available neck-mounted activity meter to detect cows about to ovulate in two paddock-based Holstein-Friesian dairy herds. The activity monitoring system recorded cow activity count in 2-hourly periods. Study I investigated the...

Abstract

The aim of this study was to compare the reproductive performance, milk production, live weight, and body condition loss during early lactation of purebred Holstein (H) cows to Jersey × H (J × H) crossbred cows in 4 Victorian herds. Cows of H and J × H breeding were managed together within each...

Abstract

Genetic progress in dairy cattle is largely determined by the merit of bulls used as sires of each generation. The aim of this paper was to evaluate the traditional selection of dairy cow bulls by artificial insemination (AI) organizations, based upon pedigree selection (PS) and progeny testing...

Abstract

Past breeding strategies for dairy cattle have been very effective in producing rapid genetic gain to achieve industry targets and raise profitability. Such gains have been largely facilitated by intense selection of sires combined with the use of artificial insemination. However, this practice can ...

Abstract

Two breed groups and 3 management levels were randomly assigned to 60 lactating cows to study the effects of breeds and management levels on milk yield under small farm conditions. 10 cows were allocated to each treatment combination. The 100-point standard score for the feeding and management was...

Abstract

Cattle. Of 953 bulls fertility-tested on 72 farms, 529 passed the test, 315 were retested and 109 failed. Causes of infertility in 143 herds are also given. In AI, a change from glass ampoules to French plastic straws took place, using an egg yolk-milk diluent. A system of quality control was...

Abstract

Previous books in Longman's Tropical Agricultural Series have dealt with cattle production only to a limited extent, and Dr. Payne's latest contribution is a welcome addition; however, it is perhaps unfortunate that it has had to be produced in two volumes. With the present high price of books, few ...
