The study of the strength and significance of four biological parameters on the body weight of goose.

ABSTRACT

Alternative products such as those from high-value protien animals have increased the demand for the production of high-quality chicken meat in past few years. This study examines the impact of two distinct feeding types on goose body-weight, as well as the genetic variation of growth hormone (GH) and pituitary-specific transcription factor (Pit-1) genes in ten goose populations using single nucleotide polymorphism (SNP) markers and PCR-RFLP analysis. Both genes were seen as very important for productivity, especially in light of the COVID-19 and its effect on poultry industry at the time. The findings suggest that employing genetic indicators in these two genes in conjunction with a high-fat diet may be a feasible strategy for goose selection programme aiming to increase marketing body weight, as the high-fat diet outperformed the balanced diet. The study investigates the effect of gender, 2 types of diets, breeds and the genetic variation of the two genes, four SNPs were reported to be found two at the GH gene exons C123T and C158T, and two at the Pit-1 gene exons G161A and T282G. Certain genotypes were found to have a substantial effect on the marketing body-weight of goose, which varied depending on the tested breeds. However, in terms of gender, males report higher and better performance levels than females. Diet, breeds and genotype interaction, and breeds, gender and genotype interaction were found to have a minor effect on goose body weight. However, diet, breeds, gender, SNP locus, diet and breeds interaction, and breeds and gender interaction were found to have a significant effect on goose body weight, as indicated by the effect size results.
