AB  - The purpose of this study was to investigate fertility in the ewes of MIS sheep population following synchronized oestrus in anoestrus season and natural oestrus during breeding season. Research was carried out on an experimental sheep farm of the Institute for Animal Husbandry in Belgrade. The study included 76 ewes and 6 rams of MIS sheep population (three breed crosses of Pirot Pramenka, Württemberg and Ile de France breed). In anoestrus season, oestrus was synchronized in 43 ewes using progestagen impregnated vaginal sponges (30 mg fluorogestone acetate) in combination with 750 IU PMSG. During the breeding season, 33 ewes were bred naturally to 6 rams, without the use of exogenous hormones. Teaser rams with marking-harnesses and abdominal aprons were used to detect females in oestrus. Obtained fertility and productivity results in anoestrus and breeding season were as follows: lambing rate 69.77% (30/43) and 100% (33/33) (P<0.05).

AB  - Research conducted on 16 dairy farms in Serbia has shown that poor housing conditions represent one of the major dairy cows’ welfare problem in our country. This is also an area of animal welfare in which the greatest difference in relation to the situation in EU countries can be observed. Poor comfort conditions are estimated based on a high share of cows that lie outside their lying area (36.5%) as a consequence of inadequate or insufficient  size of lying areas. Investigated the farms showed a very poor state of hygiene of dairy cows, with a high percentage of cows with the contaminated lower parts of the legs (84.6%), rump (71.3%) and udder (60.0%), which indicates the inadequate hygiene of lying areas and facilities, insufficient amount of bedding but also disorders of rumen digestion. The biggest welfare problems are present on farms with tied system, also the presence of grazing in our conditions, unlike the EU, is also insufficient from the standpoint of ensuring the welfare of dairy cows.
