EVALUATING SHEEP’S COLOSTRUM ACCORDING TO THE TIME FROM THE CALVING BY THE REFRACTOMETRIC METHOD
Abstract
The purpose of the study was to determine the effects of breed and time post-partum on the quality of the sheep colostrum. In this study, colostrum samples taken at different times post-partum from two different breeds of sheep (Țurcană and Asaf) and were compared using the Brix refractometer and the colour score. The sheep included in the study were placed in paddocks depending on breed. In the first week post-partum, seven colostrum samples (milk) from each sheep were collected, at 4, 12, and 24 h, then twice a day. According to the data obtained from the study, there was a difference in the composition of the colostrum depending on the breed and the duration of milking (p <0.05). Colostrum Brix values in the first and second milking proved to be greater in Țurcană than in Awasi (p <0.05). In addition, it was determined that the colour score decreased in time post-partum, and this decrease was statistically significant (p <0.05). In conclusion, as the quality of the sheep colostrum varies depending on breed and time, the quality of the colostrum administered to the lamb should be determined to ensure the health and performance of the lamb. In our study, it was observed that the colour score has decreased as the Brix value has been reduced in intensity. There was a decrease in the colour score depending on the time post-partum and that this decrease was statistically significant. In addition, it was observed that the colostrum samples taken from the Țurcană breed were of a lower quality than those in the Assaf breed, which had the highest colour score.
