AB  - The temperature-humidity index (THI) is conventionally used to measure heat stress. The aim of this paper is to determine the influence of THI and THI+metabolic parameters in prediction of milk production. A total of thirty Holstein-Friesian cows were exposed to heat stress and the THI values, milk production and metabolite concentrations were measured on days 0 (in the thermoneutral period), 7 and 14 after the exposure. The average daily THI values obtained were 65 +/- 1.05 (day 0), 75 +/- 1.1 (day 7) and 77 +/- 1.4 (day 14). Heat-stressed cows were found to exhibit a decrease in milk production, contents of glucose and non-esterified fatty acids (NEFA) and the glucose-to-insulin ratio (G:I), whereas the levels of insulin, tumor necrosis factor-alpha (TNF-alpha) and the revised quantitative insulin sensitivity check index (RQUICKI) turned out to be elevated. THI can explain 37% of the milk production variance. The percent variance explained is significantly higher after the addition of metabolic parameters in the THI+glucose (58%) and THI+glucose+TNF-alpha (65%) models and non-significantly higher after the addition of other metabolic parameters. Partial correlation analysis showed that a correlation between milk production and THI is significantly dependent on glucose. TNF-alpha showed a tendency to regulate the above-mentioned correlation, while other metabolic parameters showed a non-significant effect on the correlation between THI and milk production. It was concluded that variation in milk production during heat stress could be better predicted when THI is used in combination with glucose and TNF-alpha as a metabolic predictor. The effect of glucose and TNF-alpha in milk production during heat stress would be investigated in the next stage of our research.

AB  - In 1893. Jovan Zivanovic notes that based on the color of the abdomen of bees, two varieties of bees are present in Vojvodina, one dark and the other with two yellow rings on abdomen. Up to the present time there are mixed opinions about the presence of one or more populations of bees in Vojvodina, especially about the presence of the yellow variety in Banat. The aim of this paper is to establish the existence of one or more populations of bees, using genetic analysis of bees. Evaluation of genetic connections, diversity within the population and structure of the bee population in Vojvodina, were calculated on the basis of allele variation of 25 microsatellite loci. A genetic typification of the following microsatellites was performed: A8, A14, A24, A29, A43, A79, A88, A113, Ac11, Ac88, Ac139, Ac306, Ap15, Ap68, Ap85, Ap90, Ap223, Ap224, Ap226, Ap249, Ap273, Ap274, Ap288, At168, At188. 92% or 23 loci proved to be polymorphic in samples of bees from Srem and Backa, and 88% or 22 loci proved to be polymorphic in samples of bees from Banat. Heterozygosity calculated for the whole population is not significantly different from the expected heterozygosity. It was found that the obtained genetic differences between bees of Srem and Backa, and Banat region are not sufficient for these two populations to be considered separate.
