  Performance of starter broilers fed raw Pigeon Pea [Cajanus cajan (L.) Millsp.] Seed Meal (PSM) diets supplemented with lysine and or methionine was determined with 270 unsexed broilers. The experimental design was 2 x 4 factorial in a Completely Randomized Design (CRD), with each dietary treatment replicated three times and 10 broilers per replicate. The factors were inclusion level of raw PSM (30 and 40%) and amino acid supplementation (no supplementation, lysine, methionine and lysine + methionine). There was a conventional maize-soybean diet as positive control while raw PSM without supplementation was the negative control. Lysine and methionine supplementation were 0.10 and 0.25%, respectively. Performance criteria measured were weight gain, feed intake, Feed Conversion Ratio (FCR), Protein Efficiency Ratio (PER) and live weight at 4th week. Results showed that broilers fed methionine or lysine + methionine supplemented diets had significantly (p<0.05) higher live weight, live weight gain, feed intake and significantly (p<0.05) lower protein intake than broilers fed diet supplemented with lysine. Amino acid supplementation significantly (p<0.05) affected only live weight and daily weight gain of broilers. The diet of 40% raw PSM significantly (p<0.05) increased cost per kg feed and daily feed cost more than 30% PSM diet. It was concluded that starter broilers could be fed up to 40% raw Pigeon Pea Seed Meal (PSM) diet without adverse effect on performance of starter birds. However, the diet of 30% PSM should be supplemented with methionine and that of 40% with lysine + methionine.

  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.
