Description A cross-sectional survey covering 63 households (HH) in three administrative locations of Limuru Division in Kiambu District was carried out by means of a structured questionnaire. The three locations with high contact (HCL), medium contact (MCL) and low contact (LCL) of extension respectively, were selected on the basis of their exposure to government extension service. Twenty-one HH stratified by wealth status, (rich [R], medium [M] and poor [P]) were randomly selected from each location. The information gathered included farm/farmer characteristics, dairy herd structure, farmers’ exposure to extension agencies and participation in extension activities, and performance and level of farmers’ knowledge and practice of dairy technologies. The data was subjected to descriptive analysis and analysis of variance to establish the extent to which extension service affected farming practice.
Only 32% of the farmers were in contact with the government extension service. Dairy cooperatives and neighbours were the most important sources of information to all the farmers regardless of location and wealth status. HCL and MCL farmers ranked field days first in extension delivery, while LCL farmers did not express a preference. Knowledge of all dairy technologies was low across locations and wealth groups. However, farmers who were exposed to government extension service both knew and practised more technologies than the LCL farmers (p< 0.05), particularly in technologies related to feeding of napier grass and concentrates. Extension contact had a positive effect on uptake of technologies across extension contact groups, regardless of wealth group, implying that there was need for sustained extension farmer contact. The results showed that field days were the best method of information delivery and therefore needed to be enhanced.

To assess suitability of milk urea nitrogen (MUN) concentration as an indicator of nutritional status, data on feed offered, body condition, live weight and milk yield was collected from 21 farms for a period of 12 weeks. Milk samples were also taken and analysed for MUN concentrations. Napier grass comprised at least 60% while concentrates formed less than 5% of the total feed offered. The average total dry matter on offer was 2.54 kg/ 100 kg liveweight and average milk yield was 5.5± 3.55 kg. Body condition scores (BCS) taken on a scale of 1 to 5 showed an average score of 2±0.62 Average live weight was 323.6± 47.1 kg and MUN 17.4±5.14 mg/100ml. MUN showed a non-significant negative correlation with dry matter (DM) offered, milk yield and BCS. There was a significant (P< 0.01) positive correlation between milk yield and both DM offered and body condition score. Metabolisable energy-protein (ME:CP) ratio and DM crude protein content in g/kg were also significantly (P
