Comparative Analysis of Compliance of Genetic Potential of the Race for Milk Production Breed of Goats Alpina in Muncipality of Struga in the Republic of Macedonia

Abstract

Alpine race belongs to the most dairy breeds of goats, whose race genetic potential for milk production amounts to 900 liters per lactation, which lasts about 280 days. The purpose of this research is to carry out a comparative analysis of the implementation of the race genetic potential for milk production in the Alpine breed reared in the municipality of Struga R. Macedonia. The survey was conducted in the municipality of Struga on a sample of 20 individual goat breeders of this race. The smallest variation of the variation width (VŠ = (Max-Min) in the sample ranges from 495 liters or 55 %, and the biggest variation of the variation width is 644 liters or 71.5 %. The average deviation of the progress genetic potential for producing milk of goats of the Alpine breed in Municipality of Struga with extensive local technology compared to race genetic potential for milk production (which is 900 liters per lactation) variation of the variation width VŠ=(Max–Min) is 571 liters or 63.4 %. From the results, the sample of 20 goat breeders, which is chosen based on: the use of similar technology for accommodate goats, assistive technology equipment and tools, micro-climatic conditions, selection and improvement of the quality of the resulting offspring and nutrition, we can conclude that all breeders have derogation in fulfilling the genetic potential for milk production of goats of the Alpine breed in Struga in the ratio of the race genetic potential for milk production.
