Abstract

This study evaluated the body weight, weight gain, body measurements, and genetic diversity of the Growth Hormone (GH) gene in male and female Sentul-Arab (SeA) crossbred chickens. It also explored the association between the GH gene and these traits. The research involved 30 male and 30 female SeA chickens reared from day-old chicks (DOC) to four months of age. The experimental method used direct observation to collect data, including body weight, weight gain, body measurements, and blood samples. Data were analyzed using t-tests, the Hotellings T test, and Principal Component Analysis (PCA). Molecular analyses assessed genotype and allele frequencies, Hardy-Weinberg equilibrium, heterozygosity levels, and Polymorphic Information Content (PIC). The results indicated that male SeA chickens had significantly higher (P0.05) body weight, weight gain, and body measurements compared to females. GH gene analysis revealed polymorphism, with genotype frequencies of +/+ (0.43), +/- (0.35), and -/- (0.22), consistent with Hardy-Weinberg equilibrium. The heterozygosity levels indicated moderate genetic diversity, while the PIC value fell within the low category. In conclusion, male SeA chickens exhibited superior body weight, weight gain, and body measurements compared to females, with chest circumference and shank length being critical indicators of body size. The polymorphic GH|TaqI gene was associated with body weight, weight gain, and body measurements, with the +/+ genotype showing the most favorable effects.

Abstract

Increased  production  of  meat  has  to  be  done  to  meet  the  needs  of  the  animal  protein  demand continues  to  increase,  this  study  aims  to  look  at  the  possibility  of  accelerating  the  implementation  of selection with respect to the production of meat that is when the cow weaned in order to improve respos selection.  This  study  collected  data  includes  birth  weight,  weaning  weight,  weight  of  one  year  and  post-weaning growth rate and identify the lineage of every cow that became the object of research. The study was conducted by analyzing the data to obtain heritability value weaning weight, weight of one year and post-weaning growth rate and the value of genetic correlation between cow weight and weight one year post-weaning growth rate.  The results showed heritability values weaning weight, weight of one year and post-weaning growth rate  include  high  category,  respectively  were  0.62 ±  0.40,  1.05  ±  0.59  and  1.25  ±  0.63.  The  value  of genetic correlation between weaning weight and weight one year post-weaning growth rate was positive and included high category, each is 0.51 and 0.55. This means that selection on weaning weight increase will  be  followed  also  by  the  increasing  weight  of  one  year  and  post-weaning  growth  rate,  selection  on weaning  weight  will  accelerate  the  implementation  of  selection  of  the  parameters  related  to  meat production, so as to increase the selection response per year.
