The effects of increased dietary protein on the performance of West African Dwarf (WAD) goats infected with Haemonchus contortus were investigated. 28 pubertal 9-12-month-old female goats were divided into two equal groups A and B and fed on high and low protein diets, respectively, from day 1 of pregnancy (day of mating) to 6 weeks post-partum. Each animal was trickle infected with a total of 2400 infective larvae of H.

The effect of dietary protein on the pathophysiology of Haemonchus contortus infection in reproducing first pregnancy West African Dwarf (WAD) goats was studied. Eighteen 10-12-month-old pubertal female WAD goats divided into two equal groups were used and confined separately. One group was maintained on high-protein diet (HPD) while the other was maintained on low-protein diet (LPD) from day 1 of pregnancy up to week 6 post-partum.

The ethylacetate-insoluble fraction of the methanol extract of "Ogwu Odenigbo" a popular Nigerian traditional herbal medicine for typhoid fever prepared from the stem bark of Cleistropholis patens Benth, (Annonaceae), was separated into 13 semi-characterized constituents by preparatory TLC. The in vitro antimicrobial activities of the 13 fractions were quantitatively and/or qualitatively assessed by the agar well diffusion method using Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhinium, Aspergillus niger and Candida albicans. The steroidal fraction was about 20 and 15 times more potent than penicillin and chloramphenicol respectively against B.

Antifertility activity of a triterpenoid glycoside, DSS, isolated from the root of Dalbergia saxatilis was investigated in female Wistar rats of breeding age. When administered by gastric intubation at a dose rate of 200 mg kg(-1)body weight at the premating period, conception was inhibited in 71.4% of the treated animals.

A study was undertaken to determine the rumen DM and CP degradability characteristics of soyabean, canola seed, peanut, palm kernel and Leucaena leucocephala leaves. The oilseeds were either treated with n-hexane to extract the fat or left untreated. Nylon bags were incubated in each of four rumen cannulated sheep for 0, 2, 4, 6, 12, 24 and 48 h.
