Effects of Using Calcium Propionate and Trisodium Citrate in Dairy Cows on Daily Milk Yield and Milk Quality

Abstract

In the current study, 3 groups with similar characteristics were formed in Uşak Cattle Breeders Association Research Farm. A total of 21 cows, which were the third and fourth lactation, were selected and grouped as including 7 Holstein cows in each group. The animals in the first group were given 143 g / kg calcium propionate and the animals in the second group were give 30 mg / kg trisodium citrate orally for two months. The animals in the third group received no additives as a control group. In the farm where the samples were taken, the maintenance and feeding conditions were carried out in optimum conditions. Somatic cell count (SCC), protein, fat, dry matter, lactose, Ph parameters and daily milk yields were examined in the collected raw milk samples. As a result of the quality analysis in the collected milk, in the groups given calcium propionate and trisodium citrate, there was no statistical difference between the groups in all the parameters except for the number of somatic cells (p>0.05). However, a very significant difference was observed in the mean number of somatic cells in the cows treated with trisodium citrate (p<0.001) and Trisodium citrate administration was found to help reduce the number of somatic cells in milk.
