Dynamics of large intestine linear parameters in quail meat breeds

The dynamics of large intestine growth at the age aspect in the meat quails of Pharaoh and Texas breeds is examined at the range of 1-,10-, 30-, 40-, 50-days of age (n=9) by the complex of morphological techniques. The length of large intestine within the period from 1-day to 50-day age is 2.3-79.9 cm and 1.5-73.8 cm. The length of the right and left caecum in daily quails of the Pharaoh breed is 1.2-2.3 cm. Until the age of 30 days, their length indicators increase, the largest - on the 10th day - up to 146.25-152.12 %. Then there is a decrease in the linear indicators of the length of the intestines up to the 50th day by 15.45-26.08 %. The length of the rectum in Pharaoh breed increases until the age of 10 days, after which the parameters become smaller and increase again by the 40th day, then remain unchanged until the end of the study. In the quails of Texas breed, the rectum increases since their birth equal to the age of quails that can be seen mostly on the 10th day - 220.83 %. Linear indicators of the right and left caecum in quails of Texas breed increase since the first days of the life after their birth till 30 days and the highest indicator is at the age of 10 days - 138.96-141.25 %. The length of the guts decreases since the 30-day age the quails of Texas breed till the 50-day age. The minimum of the diameter and the length of the large intestine in the quails of Pharaoh and Texas species were recorded at the 1-day age.
