Effects Of Graded Levels Of Ethanolic Piliostigma thonningii Bark Extract On Performance Of Broiler Chicken

Twenty day old broiler chicks were used to investigate the effects of graded levels of ethanolic Piliostigma thonningii bark extract in diet on feed conversion efficiency and performance. They were divided into four equal groups, maintained on starter feed for 6 weeks and on finisher for another 4 weeks. As from their second week of age those in groups A, B and C were fed diets containing 0.5, 1.0 and 2.0mg of the extract per kg feed respectively. Values of the extract were doubled from 7th to 10th week of slaughter age. Control group D received normal diet. Water was provided ad – libitum. Daily feed and water intake, weekly live weight gain, live weight relative to organ weights at slaughter were determined. Faeces were sampled on 4th and 8th weeks for helminth eggs and coccidial cysts. Animal groups fed diets containing plant extract showed short-lived mild neurological symptoms. All groups responded positively to treatment against respiratory distress. Inclusion of plant extract in diets relatively promoted feed conversion efficiency and broiler growth particularly at its threshold level of 1.0 mg/kg feed. Optimum effect of the extract occurred by the 5th week. Feed intake correlated positively with water intake (corr. Coeff. = 0.6-0.8). Traces of eggs and cysts seen in the treatment groups (A,B,&C) differed significantly with those of the control group (.D.)It is concluded that the extract may be included in broiler diet at 1.0mg/kg feed.

Evaluation of rumen ingesta based-diet as alternative feed stuff for growing rabbits.

Trente lapins croisés (lapin blanc de la Nouvelle Zélande x race locale) ont été utilisés dans une expérimentation pour évaluer l\'effet des rations à base d\'ingesta du rumen sur la performance des lapins et sur les propriétés sensorielles de leur viande. Trois rations alimentaires: ingesta du rumen (RI) séchés au soleil ; aliment pour volaille sous forme de pâtée (GM) et un mélange de RI et de GM ( ratio 2:3 de RI /GM) ont été servies aux lapins. La consommation alimentaire, le gain de poids et la qualité de la carcasse ont fait l\'objet d\'évaluation. Il y avait une différence significative quant à la consommation alimentaire entre les lapins nourris de RI & GM et ceux nourris de GM (p < 0,05). Les lapins servis de RI & GM avaient un gain de poids nettement (

Comparative studies on the haematological and serum biochemical changes in single and mixed Trypanosoma brucei and Trypanosoma congolense infections in rabbits.

The haematological and serum biochemical changes were studied in rabbits infected with Trypanosoma brucei, Trypanosoma congolense and mixed infection. Twenty male chinchilla x New Zealand white cross bred rabbits were divided into 4 groups (A – D) of 5 rabbits each with group A infected with T brucei, group B; infected with T congolense, group C infected with mixed T brucei and T congolese and D served as the uninfected control. The infection was well established by day 4 post-infection (PI). The infections led to decrease in packed cell volume, haemoglobin concentration and erythrocyte count and increased total leucocyte count. The T congolense infected group maintained higher PCV and Hb values than the T brucei only and mixed infected groups. The total leucocyte count increased significantly (p&lt;0.05) following infection and on day 21 PI, the T brucei infected group was significantly (p&lt;0.05) higher than other groups. However, the increase in leucocyte reversed from day 28 PI. There was decrease in mean creatinine levels with the T brucei infected group being significantly (p&lt;0.05) lower than the control on days 14, 21 and 28 PI but did not differ significantly with mixed and T congolense only groups. The T brucei and T congolense infected groups had increased in mean urea values following infection and were significantly (p&lt;0.05) higher than mixed and control groups on days 21 and 28 PI. The mean AST and ALT values increased in all infected groups following infection and on day 35 PI, the infected groups were significantly (p&lt;0.05) higher than the control. The results showed variations in pathogenesis of trypanosome species in rabbits.Key words: rabbit, trypanosomes, pathogenesis, haematology, serum biochemical
