AB  - The study aimed to determine the effect of different fixed factors (breed, region, calving year,
calving season, parity and lactation stage) on daily milk production (yield and content) of four
dairy cattle breeds under the heat stress conditions (THI≥72). The research was conducted
on a set of test-day records of four dairy cattle breeds (Simmental, Holstein-Friesian, Red
Holstein and Brown Swiss) reared in the Republic of Serbia (Region of Mačva, Podunavlje and
Šumadija). The statistical analysis included test-day records collected in the period from the
beginning of the year 2012 to the end of the year 2019. Based on the performed analysis, it
could be demonstrated that all the effects included in the statistical model (breed, region,
calving year, calving season, parity and lactation stage) statistically highly significant (p<0.001)
affected daily milk production (yield and content) of cows reared in the terms of the heat stress
conditions. The highest daily milk production was determined in the region of Podunavlje, and
by the Holstein-Friesian breed. Furthermore, dairy cows calved during the spring season, in the
third lactation and from the 61st to the 120th day of lactation, had the highest milk production
during the summer period in an environment characterised by heat stress. Also, daily milk yield
of cows in a heat stress environment decreased in the period from June to September. The
results obtained indicate different animals’ responses to heat stress concerning the animal’s
breed, rearing region, calving year, calving season, parity and lactation stage.

AB  - The study of the link between genes controlling protein polymorphism and milk
performance traits of domestic animals has great economic importance from a
selection point of view, as it reduces the generation interval, leading to increased
productivity in livestock. The objective of this paper was to establish the influence
of genetic β -lactoglobulin polymorphism on the quantity and quality of milk of the
simmental breed in Serbiа. For the research blood samples were taken from a total of
157 Simmental cows. The genotypes of Simmental cows for β-lactoblobulin and
their effect on quantitative milk performance traits were determined using the PCRRFLP analysis. The variability of traits influenced by the genetic polymorphism of
β-lactoblobulin was statistically very highly significant (p <0.0001) for milk yield in
standard lactation and milk fat and protein yields, while it showed no statistically
significant variability (p> 0.05) for content of milk fat and protein. The AB genotype
cows achieved a 121 kg and 338 kg increase in milk production compared to the BB
genotype and AA genotype cows, respectively.
