Seventy-four weekly weighband and weighbridge comparsons were made on 21 pure and crossbred Malawi zebu cattle. The mean correlation coefficient obtained was +0.977. The weighband over-estimated the liveweight by a mean of 42 lbs, which was equivalent to an 8.5 percent error. The highest individu...

Trials were conducted at Citedze research station in Malawi between 1972-75 on two forages species, namely Ntchisi panic (Panicum maximum CV.Ntchisi) and pearl millet (Pennisteum typholdes CV. Katherine). The purpose or the study was to evaluate the two forage species performances as a green feed...

Dorper sheep weighed 8 kg more than Red Maasai at 1 year of age. Due to better growth rates and higher adult weight, Dorper consumed more pasture than Red Maasai. It has been calculated that in terms of percentage 83 Dorper breeding ewes and followers consume as much pasture as 100 Red Maasai bre...

This report describes the results from the lambing/kidding season of October/November 1976. A total of 219 lambs were born out of which 213 and 204 survived to weaning (at the age of 3 months) and to 6 months of age, respectively. Conception rate was 90% among the ewes with a lamb percentage of 1...

The study was carried out to investigate the milk yield potential of Bunaji and Sokoto Gudali breeds, the environmental factors influencing dairy traits and to estimate the genetic parameters of some of the economic dairy traits. The data were 2177 records from 545 Bunaji cows and 928 records fro...

Analysis of fifteen years (1970- 1984) data on Mpwapwa cattle (12% B. taurus) and their crosses, Backcross (34% B. taurus) and Crossline (56% B. taurus) was carried out. Data pooled over the first five lactations showed that for Mpwapwa, backcross and crossline cows, lactation milk yield averaged...
