Evaluates the reproductive and lactational performances, length of productive life of the Jersey breed from records for 1960 to 1988 in coastal lowland semi-humid Kenya. Reports estimates of reproductive and lactational performance, the effects of non-genetic factors on performance and estimates ...

Genetic and environmental variation in reproductive and lactational performance of Jersey cattle in the coastal lowland semi-humid tropics
Summarises the critical steps for designing a comprehensive breeding system. Breed (genotype) comparison and utilization are discussed with ref. to breeding policy, environment and management systems, genetic parameters, purebreds, F1 crosses, rotational crossing, and F2 and F3 generations of bre...

The note is divided into five parts, viz, sampling methods, multicollinearity or intercorrelation, autocorrelation, and estimable and testable functions. The first part discusses sampling procedures, sample size determination, random sampling, sampling by deliberate stratification, blocking and i...
