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...

Genetic diversity of the indigenous cattle of Kenya, Uganda, Ethiopia and Tanzania using high-density SNP data. The indigenous cattle make a significant contribution to the livelihood of many communities in Ethiopia, Tanzania and other countries in eastern Africa. Here, we identify the genetic st...

Cost-effective genotyping of livestock species can be done through a process which involves genotyping part of the population using a high density (HD) panel and the remainder with a lower density panel and then use imputation to infer the missing genotypes that are not included on the low densit...

The Menz and Horro highland sheep breeds are being evaluated at the ILCA Debre Birhan research station in Ethiopia for between-and within-breed genetic variation for resistance to internal parasites. The experimental design involve mating, for each breed, 150 ewes with 10 rams to lamb at the begi...

Sub-Saharan Africa is rich in animal biodiversity. Over 95 percent of the continent's domestic ruminants are indigenous. In Africa, indigenous livestock breeds support the majority of smallholder rural farmers for whom these genetic resources are important for improved nutrition, income and as in...
Reproductive performance and disease data were recorded for 2 years on 1,824 dairy cows in smallholder farms using participatory approaches and onfarm recording. Most animals experienced one service to conception. Calving intervals were long, ranging between 261 and 761 days, with an average of 4...

Prediction models were developed from isotope dilution space (D2O) and live animal measurements (heart girth, height at withers, body length and tail volume measurements) to estimate chemical body components of indigenous tropical fat-tailed sheep breeds in vivo. A STEPWISE multiple regression pr...
