A financial analysis was performed to assess the performance of three acaricide-treatment groups of indigenous breeds (Zebu and Nganda) of cattle on a ranch in Luwero District, Uganda. The treatments were based on different frequencies: twice-a-week dipping, once-a-month dipping and no tick contr...

Bioassay of acaricide resistance on three common cattle ticks was carried out on four farms in Holotta area, Central Ethiopia, using a standardized FAO Acaricide Resistance Test Methods. Larval progeny of Boophilus decoloratus, Rhipicephalus e. evertsi and Amblyomma variegatum were subjected to l...

Two bovine bacterial artificial chromosome clones were screened by PCR to amplify the tumour necrosis factor alpha (TNFA) gene. DNA extraction and Southern blotting and probing with a (GT)10 oligonucleotide were performed, followed by cloning into the pUC19 vector. A 0.9 kb fragment containing se...

Three experiments were conducted in successive years on crossbred suckler cows on a farm in a semi-arid area close to Nairobi, Kenya. The cows were mated seasonally to calve approximately 1 month before the rainy season (March to May). The effects of milking once daily and supplementation (2 kg/h...

In a field study in Kenya, 55 plots in a Pennisetum purpureum sward were cut in rotation to give a 55-d regrowth cycle. After cutting, each plot was weeded and given 6.3 kg N + 4.5 kg P/ha. The daily DM production varied from 25 (dry season) to 178 kg DM/ha (rainy season). The mean DM yield after...
