A selection index procedure which utilizes both, purebred and crossbred information was
developed for the sire line of a three-path crossbreeding scheme in pigs, to predict response to …

A model was constructed and validated to determine the course of performance, revenues
and costs of dairy cows with different levels of milk production and of number of days open. …

1. Pulmonary hypertension syndrome followed by ascites is a metabolic disorder in broilers
that occurs more often in fast-growing birds and at cool temperatures. 2. Knowledge of the …

Variation in piglets weaned per sow per year is the main factor explaining differences in income
between piglet producers. This parameter is the result of prolificacy of sows and survival …

To generate information essential for the implementation of breeding schemes suitable for
village poultry producers in Ethiopia, a survey was conducted aimed at defining the …

Using deterministic methods, rates of genetic gain (Δ G) and inbreeding (Δ F) were
compared between pure line selection (PLS) and combined crossbred purebred selection (CCPS), …

In this review, consideration is given to (1) experimental designs for detection of linkage
between marker genes and genes controlling quantitative trait loci (QTL) in livestock, (2) …

Techniques which have been applied to dairy cattle to determine the optimum time for
replacement of cows were evaluated. In the marginal net revenue approach, the optimum time for …

The effect of age and housing system on genetic parameters for BW and carcass traits was
investigated. Traits were measured on broilers of different ages (48, 63, and 70 d). Birds in …

Reproductive techniques have a major impact on the structure of breeding programmes, the
rate of genetic gain and dissemination of genetic gain in populations. This manuscript …
