Abstract
This study was conducted at the College of Agriculture/University of Al-Muthanna for the period between 1/10/2020 until 30/6/2020, 60 buffaloes were used in the experiment with the aim of determining the genotypes and their distribution ratios for the PIT-1 gene. The genotypes were altered (P<0.01), which amounted to 18.52 and 81.48 respectively, and the allelic frequency was 0.10 and 0.90 for each of the two alleles A, B, respectively. Daily milk production and fat percentage were not significantly affected, milk protein percentage was significantly affected (P<0.05) in the eleventh week, reaching a maximum of 3.88±0.28 (BB), as well. Significant differences (P<0.05) were found in the percentage of genetic non-fatty solids in the first week of the study, with a maximum of 23.28 (BB). BB genotype.
