“…Many studies have investigated the relationship of different body measurements with body weight or slaughter weight (Wahid et al, 1975;Yamani et al, 1982;Abdellatif, 1999;Goswami et al, 2000;Latshaw and Bishop, 2001;Mendeş et al, 2005). In such studies, the relations between body weight and some of the body measurements have been discovered and the results have been used in estimating future steps.…”

In this study, Regression Tree Analysis (RTA) was used to predict and to determine the most important variables in predicting the slaughter weight of Ross 308 broiler chickens. Data for this study came from 224 chickens raised during three different seasons, namely spring (n=66), summer (n=66), winter (n=92). Second week body weight, shank length, shank width, breast bone length, breast width, breast circumference and body length were used to predict the slaughter weight. Results of RTA showed that among the seven independent variables only four were selected, namely; body weight, breast bone length, shank width, and breast circumference. These selected independent variables were more efficient than the others in predicting the slaughter weight. RTA indicated that the birds which had values of second week body weight >295.95 g, breast bone length >55.82 mm and breast circumference >14.18 cm or that of body weight ≤295.95 g, breast bone length >60.26 mm and shank width >8.32 mm could be expected to have higher slaughter weights.

“…Information on correlation among the pre and post-slaughter traits is quite important in poultry breeding. This is because knowing which of the pre-slaughter traits affects which of the post-slaughter traits enables the breeder to predicts what kind of products to obtain at the end of breeding programme (Mendes et al, 2005;Mendes, 2009;Yakubu and Idahor, 2009). Size and shape of various parts are the major determinants of the overall size and shape of the live bird or carcass.…”

This study was conducted to determine the influence of sex on relationship among carcass traits (carcass weight, breast, drumstick, thigh, wings) and morphometric traits (body weight, breast girth, keel length, shank length, thigh length, wing length and body length) in broiler chicken. And also to evaluate correlated relationship between the morphometric traits and carcass traits. The 60 broiler birds were divided into 2 treatment groups (male and female) each group was replicated thrice with 10 birds per replicate. The birds were rear in deep litter system till the attain 56 days of age, body weight and morphometric traits measurements were taken on the 56 day. The 18 birds (9 from each group) were randomly selected, slaughtered and the carcass traits measured and recorded. The data obtained from these studies were subjected to Pearson correlation analysis. The correlated relationship among most carcass traits and morphometric traits were significantly positive (p<0.001) with correlation coefficients ranging from 0.01-0.681 in Males (M) Females (F) and in combination of Males and Female (M+F). The correlation between morphometric traits and carcass traits showed that breast girth and live body weight were positively and significantly (p<0.001) correlated with all carcass traits in all the sex groups. The observed significant relationship among the morphometric traits and carcass traits as well as between morphometric traits and carcass traits is an indication of the existence of high level of dependency amongst these traits, thus improvement in any one of these traits would elicit a correlated response in the other traits. More so, the positive and significant correlated relationship between carcass traits and breast girth indicate that breast girth can be used as indirect selection criteria for carcass traits in broiler chickens.

“…Local turkey is becoming few in Nigeria and are predominantly the bronze-black type raised extensively (Oluyemi and Roberts, 2000). The main purpose of animal breeding practices is to improve traits of economic value (Mendes, 2005) and body weight is one of those important economic traits in the selection of animals. Fertility and hatchability are major parameters in reproduction performance which are most sensitive to environmental factors and genetic influence (Stromberg, 1975).…”

A total of 78 one day-old random-bred Nigerian local turkey poults were used to produce another 232 day-old poults in two planned experiments to characterize and discriminate Nigerian local turkey based on fertility and hatchability traits. Three phenotypic classes (black, white and spotted)were obtained as base population and used to generate F progeny. Experimental design was a randomized complete block (RCBD) with phenotypic class as major factor of interest and hatches as block. Results showed that there was significant difference (p
