3rd World Congress on Genetics Applied to Livestock Production
In his introduction to the Plenary Session of the First World Congress on Genetics Applied to Livestock Production for Sheep, Rae (1974) pointed to the wide diversity of sheep production systems throughout the world. Goats add further to this range in production environments, husbandry systems and to the variety of products for which these two domestic species are farmed. Such variety makes any consolidated review of Genetic Improvement Programs for sheep and Goats very difficult, especially if all important operational features of ~e production and marketing circumstances for each end product are to be considered in evaluating the success of …

3rd World Congress on Genetics Applied to Livestock Production
Data on 50 percent and higher Holstein Friesian crossbred genetic groups revealed significant differences with respect to age at first calving, first lactation 305 days yield, dry period and service period. 91.7 percent of the divergence among genetic groups was contributed by 305 days lactation yield. F1 crossbreds formed separate cluster. Among the higher crosses (75% and above) genetic groups involving only 2 breeds formed separate cluster from genetic groups involving three breeds. Three breed cluster was farthest from the F1 crossbreds cluster. There was an indication of all the clusters having animals of good genetic potential.
