Influence of Sex on Relationship Between Morphometric Trait Measurement and Carcass Traits in Broiler Chicken Raised in Humid Tropic

Abstract

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.

Influence of Breed and Sex on Body Weight and Conformation Traits of Turkeys

“…Poultry production holds significant importance in Nigeria, contributing approximately 6-8% to the total GDP annually and about 30% to the agricultural GDP (NBS, 2023). Beyond economic contributions, poultry farming sustains livelihoods by providing food (Sam et al, 2010;Alphonsus et al, 2012;Ebong et al, 2023). Poultry meat, renowned for its low cholesterol content and high protein levels (Stangierski and Lesnierowski, 2015), is preferred by consumers.…”

“…Poultry meat, renowned for its low cholesterol content and high protein levels (Stangierski and Lesnierowski, 2015), is preferred by consumers. Additionally, poultry farming offers organic manure for crop production and serves as a source of income and employment, especially in rural areas (Essien and Sam 2018;Efretuei et al, 2023;Sam and Okon, 2022).…”

Heterotic Effect on Body Weight, Reproductive, Morphometric and Carcass Traits of Crossbred Kits of New Zealand White and Chinchilla Rabbits

“…Production of rabbit has become very lucrative in recent times due to its numerous attributes. Some of which include high reproductive performance (Kabir et al, 2016), excellent mothering ability (Lukefahr and Cheeke 1990), ability to adapt in different environmental conditions (Sam et al, 2020a), high genetic variability (Sam et al, 2020b), low capital investment (Aduku and Olukosi 1990). Rabbit meat contains very high protein 21-22% (Dale, 2002) and low fat and cholesterol levels (Ekpo et al, 2016 ).…”

“…Body weight, Reproductive, morphometric and carcass traits are very important in rabbit production. Reproductive performance of rabbits determines the profitability and economic success of commercial rabbit breeding ( Ekpo et al, 2018;Sam et al, 2020a). Body weight and morphometric traits on the other hand are crucial because heavier body weights lead to greater economic of production in rabbit production (Fayeye, 2013).…”

Repeatability of Growth Traits in Three Strains of Broiler Chicken

“…Repeatability measures the degree of association between records in the same animal for traits expressed more than once in animal's lifetime (Bell et al, 2009). The study of repeatability of growth traits in broilers enables selection for broiler strains that will reach market weight at reasonable age for profit maximization (Sam, 2019). In addition to its use as an index of reliability of early measurements in evaluating and selecting animals for future performance, repeatability also enables farmers to estimate their future financial returns (Dalton, 1985;Rudeck, et al 2020).…”
