Data on water sources, mode of offer, watering frequency, amount of water offered, body weights and milk yield were collected from 21 randomly selected smallholder farms in Kiambu by means of farm visits and questionnaires fortnightly. Most farms (67%) had water on-farm but 76% of them needed lab...

Nineteen dairy cows were used over a 7-month period to evaluate the effect of allocating different levels of concentrate during early lactation. The animals were fed on grass hay basal diet and supplemented with either 2 Kg (LLC), 4 Kg (MLC) or 8 Kg (HLC) per day. Milk yields were measured daily,...

A survey was conducted to determine the sources and delivery of technical information to smallholder dairy farmers in Kiambu District. Sixty-three farmers in three wealth groups (rich, medium, poor) of 21 farmers each from three different locations, were selected at random from maps drawn by comm...

A survey was conducted to evaluate the use of Milk Urea Nitrogen as an indicator of nutrition status of lactating animals. Twenty-seven animals in a randomly selected sample of 21 farms in Kiambu District were monitored for nutritional status for 12 weeks. Fortnightly records were taken on feed o...

A key characteristic of the provision of feed resources under staff feeding conditions in many smallholder systems is a high degree of variability in the types and quantities of feeds used. Striking seasonal patterns have been widely observed (e.g. Gatenby et al, 1989). However, their consequence...

The effects on crossbred steer liveweight gain of alternating the same quantities of Napier grass and barley straw at five day intervals over a 40 day period was studied (Sanda et al, 1999. These animals lost significantly more weight (p<0.05) than animals on one and ten day frequencies of alter...

Due to inadequate feed supplies for livestock production, farmers throughout the tropics and sub-tropics are being encouraged to supplement low quality basal diets with leguminous forage and concentrates. The varying quality (e.g. nitrogen, lignin and polyphenol content) of these diets will influ...
