Agricultural commodity production in a changing climate scenario is undergoing sustainability challenges due to degradation of soil fertility, water and biodiversity resources. In Africa, yields for important cereals (e.g., maize) have stagnated at 1 t ha−1 due to land degradation, low fertilizer...

The Kuri cattle breeds of Lake Chad were investigated. Descriptions of rearing environment, animal morphology and breed improvement included. Data on body measurements of oxen, cows and bulls included with discussions of their exploitation, protection, improvement, selection and multiplication.
The influence of strain and sex on body weight (BW) and linear body measurements [body length (BL), height-at-withers (HW), and heart girth (HG)] and their relationships in sex groups (1-6, 7-12, 13-18, 19-24, 25-30, and 31-36 months) were studied in 720 smallholder Maradi goats of Nigeria. Sex s...

A trial was conducted on 26 male twin lambs to study the effect of creep feeding on lamb development and growth Creep feeding started when the lamb’s average age was 43 days. Lambs were weaned at an average age of 93 days. The creep feed group was fed ad libitum until the age of six months while ...
