One hundred and forty-four
(144) day old Anak 2000 broiler chicks were used to investigate the
growth response as well as organ characteristics of broiler chickens
fed graded levels of kola pod husk meal (KPHM). The birds were randomly
allotted to four dietary treatments groups containing 0%, 10%, 20% and
30% KPHM. There were two replicates per treatments with 18 birds per
replicate in a completely randomized design. The birds placed on control
diet utilized their feed more efficiently (P< 0.05) than other treatments.
The broilers fed 10% and 20% KPHM were able to convert the diet more
efficiently (P< 0.05) than the broilers on 30% KPHM. Treatment effects
on weight gain, feed: gain ratio, dressed weight, length of small intestine,
length of colon, length of caecum, weights of kidney and lung were significantly
(P< 0.05) different. Growth rate decreased significantly (P< 0.05) with
increasing level of KPHM in the diet. However, no significant (P>0.05)
difference was observed in protein efficiency ratio, nitrogen retention,
dry matter digestibility and crude fibre digestibility of the birds
fed different diets. It could be concluded that KPHM inclusion in broiler
diet up to 10% dietary level will adversely affect the performance of
broilers. |

A feeding trial was conducted to assess the nutritional value of Gliricidia Leaf Meal (GLM) on
performance, nutrient digestibility and economy of production of layer chickens. GLM was used partially to
replace maize and soyabean at 0, 5, 10 and 15% in diets A(control), B, C and D, respectively. Performance
characteristics interms of Hen day production, feed intake, body weight gain, feed efficiency and feed cost
were monitored. Chemical analysis revealed that GLM contains 24.38 Crude Protein (CP), 1.75 Ether Extract
(EE), 12.45 Crude Fibre (CF), 8.64 Ash and 45.36% Nitrogen Free Extractives (NFE). Only egg weight showed
no significant difference (p>0.05) while Henday production, feed intake feed efficiency and body weight were
significantly different (p<0.05) among dietary treatments. Feed cost (N/kg feed) was significantly different
(p<0.05) across the diet. Nutrient utilization studies (dry mater, crude protein and ether extractives) were not
significantly influenced (p>0.05) due to dietary treatments. It therefore appears that up to 15% of GLM can be
incorporated into laying chicken ration without any adverse effect. |

Clinical observations and haematological changes following gastro-intestinal worm Haemonchus contortus was investigated experimentally in West African Dwarf (WAD) kids. 10 apparently healthy kids were experimentally infected orally with 750 infective larvae of Haemonchus contortus for a period of 5 weeks. The kids were weighed, the blood and faecal samples were collected before and after infection. Student’s t-test statistical analysis was used. The clinical observations on the infected WAD kids were normal rectal temperature, normal respiratory rate, normal heart rate and normal prepatent period with muscular weakness, anorexia, intestinal distension by worms, weight loss, reduced carcass quality, reduced feed intake, diarrhea and anaemia. The infestation was characterized by responsive normocytic-nomochromic anaemia. The weight and erythrocytic values were significantly different at p<0.05 and p<0.01 compared with the control. The erythrocytic indices, the total WBC and differential leucocyte counts were not significantly different at p>0.05 and p>0.01. The weight and erythrocytic values are directly proportional to the level of presence of helminthes eggs in the faeces. |
