Describes a dynamic & stochastic simulation model, specifying its driving variables & validating it for production conditions in a study area in Botswana. Compares the simulated performance of Tswana & Simmental x Tswana cattle, analysing economic trade-offs between milk & meat production under v...

This study examined the effect of lablab hay supplementation of crossbred cows fed forages from cereal+forage legume intercropping (maize–lablab (ML) stover or oats–vetch (OV) hay) basal diets on feed intake, apparent digestibility, milk yield and milk composition of crossbred cows. Forty eight m...

Effects of supplementation with graded levels of lablab hay on voluntary food intake, digestibility, milk yield and milk composition of crossbred cows fed maize-lablab stover or oats-vetch hay ad libitum]Integration of forage legumes with cereal crops. I. Effects of supplementation with graded levels of lablab hay on voluntary food intake, digestibility, milk yield and milk composition of crossbred cows fed maize-lablab stover or oats-vetch hay ad libitum

Thirty-six crossbred cows were used in a 2 X 2 factorial arrangement in a randomized block design to evaluate forages from two cropping systems (1 and 2) and feeding levels (ad libitum, (Level1)) or 80 percent of ad libitum (Level 2) on milk yield, live weight, and reproductive performance. Crops...

Milk production and reproductive performance of crossbred dairy cows

A survey was conducted from February to June of 1997 among livestock herders in two villages of Niger, Kodey and Toukounous, on their perceptions, practice, and problems of night grazing. Cattle and sheep were the species that were taken out for night grazing by the herders. Small herd size an...

Efficient input supply and service delivery may call for a hub approach where all the necessary inputs and services are supplied in a coordinated manner, either by a single supplier or by several and separate entities in a given geographical location accessible to beneficiaries. Based on experien...
