This study was undertaken to determine the heat tolerance attributes of Nigerian locally adapted chicken as affected by strain and some qualitative traits. The experimental birds consisted of four matured strains. A total number of 120 healthy matured birds consist of30 each of Naked Neck, Normal Feather, Fulani and Frizzle feather. Each bird was monitored and measured for the number of comb cups, comb length, comb height, wattle height and width at the beginning of the experiment and recorded for each strain. Data were obtained on a daily basis (afternoon) for 12 weeks. The measurement taken include: Numbers of comb cups, Comb length, Comb height, Wattle height, and Wattle width. The heat tolerance attributes considered were the rectal temperature, pulse rate and respiratory rate. Chicken strain and sex had significant effect (P<0.05) on pulse and respiratory rates. The lowest heat stress index, pulse and respiratory occurred in the naked neck with corresponding values of 0.84, 42.65beats/min and 40.26breath/min. Female birds had higher physiological values. Comb length and height differed significantly (P<0.05) with pulse and respiratory rates while no significant (P>0.05) effect was shown in rectal temperature. Comb cups also affected (P < 0.05) pulse and respiratory rates. The lowest pulse rates were obtained in chicken with measuring 5cm high and 4cm long. Regarding respiratory rate and heat stress index, the lowest values were recorded in chicken having combs that measured 8cm high 7cm long. The lowest respiratory and pulse rates were observed in chicken whose comb had 14 and 8 cups respectively. There was significant (P < 0.05) wattle size variation in pulse and respiratory rate and heat stress index. The lowest pulse respiratory rates were observed in 7cm wattle height while the lowest respiratory and heat stress index occurred in chicken whose wattle measured 7cm in diameter. However, 6 cm wattle width had the lowest pulse rate. It can therefore, concluded that strain, sex and some qualitative traits in chickens affect heat tolerance attribute.

The study was conducted in Edu local Government Area of Kwara State to analyze the contribution of dairy farming to household welfare. It highlighted the socio-economic characteristics of the respondents, managements practices, dairy products, household welfare and constraints that hindered effective production in dairy farming. Data were collected by using structured interview schedule administered on 80 dairy farmers randomly selected. Analysis of data were carried out using frequency counts and percentages. About 39.0% of the respondents were between the age ranges of 41–50 years, while 93% were male. 83.0% were educated, and 90.0% had more than five dairy cattle in their herd. All the respondents carried out management practices in dairy enterprise and mentioned the products, Milk, Cheese, Cream, Butter, Nunu, and MaisanuandOriamo are the products obtained from dairy farming. Majority (93.8%) of the respondents indicated high cost of supplementary feed and finance as the constra...

This study examines the effect of varying levels of Leucaena leucocephala leaf meal diet on the growth performance of weaner rabbit. The purpose of this study is to examine the nutritional worth of including Leucaena leucocephala leaf meal as a plant protein source in the diet of rabbits. Twelve weaner rabbits were used for the study with four diet groups containng 0, 5, 10 and 15% Leucaena leucocephala leaf meal and measurements taken in a 50 day experimental period were: final body weight gain, feed intake, feed efficiency ratio, and digestibility coefficient for crude protein, crude fibre, ether extract and ash contents. Three rabbits were randomly allotted to each dietary treatment after balancing for sex and body weight, and kept in individual pens. Data collected were subjected to analysis of variance. Results show that the body weight gain of the rabbits decreased as the proportion of Leucaena leucocephala leaf meal in the diets increased, except with 10% inclusion. The final...

The study was carried out to evaluate the genotype-sex interaction in relation to heat toleranceattribute of pure and crossbred chicken progenies in a 12-week study. A total of twohundred and seventy two chickens were used for this study. These consisted of 150purebred chickens consisting of Isa Brown, Fulani Ecotype,Naked Neck, Normal Feather and Frizzled Feather; and 122 crossbred comprising, NN x IB, FF x IB, IB x NF and IB x FE progenies. Under natural heat stress environment genotype were significantly (P<0.05) affected by rectal temperature, pulse rate and respiratory rate. The Isa Brown had the highest value of rectal temperature (41.74 o C), respiratory rate (56.76 breath/min), pulse rate (56.83beat/min) while normal feather obtained the lowest values of these traits. Crossbred of FF x IB had the highest value of rectal temperature, respiratory and pulse rates of 41.75 o C,58.67 breath/min and 54.49beat/min respectively. Significant (P<0.05) effect was obtained among t...

This experiment was conducted to assess the effect of chicken genotype on the growth performance, feed intake and feed conversion efficiency of the progenies resulting from purebred (Giriraja (Gr) X Giriraja (Gr)), straight (Gr male X Alpha female), reciprocal (Alpha male X Gr female) and Alpha male X White Leghorn (WL) female crosses. Data obtained on body weight, body length, breast girth, keel length, feed intake and feed conversion efficiency in a Completely Randomized Design were analysed using one-way analysis of variance for the fixed effect of chicken genotype. Generally, all growth traits, feed intake and feed conversion efficiency were significantly affected (P < 0.05) by chicken genotype. Body parameters, feed intake and feed conversion efficiency increased as birds advanced in age. Progenies resulting from mating of Giriraja X Giriraja chickens had the highest body weight, breast girth and feed conversion efficiency. However, the reciprocal crosses of Alpha X Gr resul...

ENGLISH/ ABSTRACT (ENGLISH/ ABSTRACT (ENGLISH/ ABSTRACT (ENGLISH/ANGLAIS ANGLAIS ANGLAIS ANGLAIS)) The study was conducted to determine the effect of age and cage position on the growth traits of harco-black cockerel chicken. Two hundred and fifty birds were used for the study and were randomly placed equally in the upper and the lower tier cage for the period of sixteen weeks. The parameters taken were body length (BLT), comb length (CLT), Keel length (KLT), Drumstick (DSK), Shank length (SLT) and Chest girth (CGT). Significant effect ( p < 0.05) of cage tier and age on DSK, KLT, SLT, CGT and CLT of Harco-black cockerel were observed. The upper tier cage shows higher significance for most of the growth traits measured. The correlation coefficients at 9 th week of age were only highly positively significant ( p < 0.001) correlation between CGT and KLT while that of 14 th week of age shows a highly negatively significant ( p < 0.001) correlated between the BLT and SLT at the...

ENGLISH/ANGLAIS] This study is focused on the effect of coat pigmentation and wattle genes on the adaptation performance of West African Dwarf (WAD) goats in the sub-humid zone of Nigeria using purposive sampling method on-farm. Data on white blood cell, red blood cell, haemoglobin, packed cell volume; sodium and potassium were obtained from five hundred and twenty (520) goats. Data were corrected for age effect and for the fixed effect of coat pigmentation and wattle genes using General Linear Model procedure of SAS. White blood cell (WBC), red blood cell (RBC), haemoglobin (Hb), packed cell volume (PCV), serum sodium (Na+) and potassium (K+) were significantly (p < 0.05) influenced by coat pigmentation genes. Brown goats with white markings (aabbss) had the highest WBC (13.01±0.19x103/μl), Na+ (138.22±0.74 mmol/litre) and K+ (3.80±0.06 mmol/litre) while Bezoar (Abz) goats had the highest RBC (13.12±0.10 x106/μl). All blood parameters were influenced (p < 0.05) by wattle gene...
