AB  - In this review paper, hygienic procedures before, during and after cow milking are discussed. The procedures for maintaining hygienic udders before and after milking, as well as maintaining the hygiene of milking units are described. The description includes the maintenance of milker's hand hygiene, udder disinfection and udder disinfection after milking. It is pointed out that these milking procedures should be carried out in a clean environment and without any disturbance to cows. In addition, the need to control the implementation of these hygiene measures is emphasized. A proper way of carrying out the hygienic procedures essentially contributes to reduction of the number of microorganisms and the number of somatic cells in milk, the frequency of occurrence of mastitis, which significantly affects quality of milk and health of milking cows.
AB  - U ovom preglednom radu razmatraju se higijenski postupci pre, za vreme i posle muže krava. Opisani su postupci pre i posle muže, kao i čistoća opreme za mužu. U opis je uključena higijena ruku muzača, dezinfekcija sisa pre muže, suvo pranje, uklanjanje nečistoće, čišćenje ili sušenje sisa, kao i postupci dezinfekcije posle muže. Ističe se da se ovi postupci
kod muže treba da odvijaju u čistom okruženju i bez uznemiravanja krava. Pored toga, navodi se i potreba kontrole sprovođenja tih higijenskih postupaka. Pravilan način sprovođenja ovih higijenskih procedura suštinski doprinosi smanjenju broja mikroorganizama i broja somatskih ćelija u mleku, učestalosti pojave mastitisa, što značajno utiče na kvalitet mleka, kao i opšte zdravstveno stanje krava muzara.

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  - In order to examine the biased milk production depending on the sex of calves, data on calving and milk yield characteristics of 15,181 Holstein type cows in PK Belgrade, Serbia were analyzed. A total of 30,362 lactations that were realized in the period from 1985 to 2017 were analyzed. Data were prepared and analyzed using the SAS software package (SAS Institute Inc. Software License 9.3, 2012). The expression and variability of investigated traits were determined using the PROC MEANS procedure, while the effect of individual factors on milk yield traits was analyzed using the PROC GLM procedure. Obtained results deviate from the views of the Trivers–Willard (TW) hypothesis. The results indicate that mothers invest more in female offspring by producing a higher milk and fat yield in the first and second lactation compared to male offspring. This is especially emphasized under better environmental conditions. The highest milk yield (7788 kg) and fat yield (271 kg) in the second lactation were achieved in the combination with two consecutive female calves in the group of higher-than-average milk production farms, and lowest in the combination of two consecutive male calves (6783 kg for the MY and 243 kg for the FY), respectively.

AB  - The aim of this study was to analyze the influence of farm conditions and season of birth on body mass, respiratory system diseases and diarrhea occurrence, and mortality during the first month of calves' life. The study was conducted on two tie-stall-system farms with intensive milk production and similar nutrition of dairy cows, but with differences in rearing conditions of calves in the first week of life. The calves were tied on lying area with straw as bedding material (farm A) or free in individual boxes with straw bedding (farm B). In the first consumption, they take 1-2 L of colostrum produced by their mother or by another cow (farm A), or 2.5-3 L of colostrum produced by their mother or by another cow or frozen colostrum (farm B). According to the results, average body mass of calves was significantly higher on farm B than of those on farm A at all ages (on birth, at 8 days, and 30 days). Mortality rate and diarrhea occurrence in calves were higher on farm B, while respiratory system diseases incidence was higher on farm A. All observed welfare indicators were very significantly (P  lt  0.01) influenced by farm conditions and birth season.
