Modelling Changes in Milk Components of Damascus Goats during Lactation

Abstract

In this study, the possibilities of determining the changes of lactation milk components in Damascus goats by mathematical models were investigated. The animal material of the study consisted of 47 Damascus goats raised in Gökçebağ village of Siirt province. Milk components were analyzed in milk samples acquired at 2-week intervals after parturition. Milk components were analyzed using the Lactoscan Milk Analyzer. Wood and Ali-Schaeffer models, which are assumed to be the most appropriate for the definition of lactation curves, were applied to the milk component data obtained to describe the change in milk components, the best fitting model was determined, mathematical and biological relationships were solved in protein and fat content, and the relationship between the parameters was examined. Samples taken from dairy goats in the local enterprise were expressed with mathematical models and the change in milk content during lactation was tried to be learned. The results are intended to form the basis for the improvement of goat milk content and breeding projects in Siirt.
