Effect of Adding Taurine on Gene Expression of GPX1 and ACACA Genes of Broiler Chickens Raised at Different Temperatures

Abstract

This study was conducted in animal production farm in Collage Agriculture - University of Anbar during 7/8 – 17/9/2022 during summer and 25/2–7/4/2023 in winter to study the effect of addition different levels of taurine to diet in gene expression of GPX1 and ACACA genes of broiler chickens (Ross 308) raised at different temperatures during the summer and winter seasons. 180 one day unsexed hatched chicks will distributed into five treatments with three replicates for each treatment, as the following T1, control treatment, T2 adding 300 mg of vitamin C per kg diet during summer and 300 mg of vitamin D in winter, T3, T4 and T5 adding 300,600 and 900 mg of taurine per kg diet respectively. The results of the statistical analysis of the two experiments showed significant effect (P≤0.01) of the addition treatments on gene expression values of the ACACA gene, as the treatments T3-T5 recorded the lowest values of gene expression during the summer and winter seasons compared to the t1 treatment. As for the gene expression of the GPX1 enzyme, the treatment T5 and T2 recorded the lowest values of gene expression during the summer and winter seasons, respectively.
