Badania przeprowadzono na ponad 8 tysiącach ejakulatów pobranych od 112 knurów. Badaniami objęto wszystkie ejakulaty pobrane i zakwalifikowane do inseminacji w czteroletnim okresie działania jednej ze stacji unasienniania loch. Nasienie od knurów pobierano dwa razy w tygodniu, metodą manualną, rano po pierwszym karmieniu. Pobrane ejakulaty poddano ocenie według metodyki stosowanej w polskich stacjach unasienniania loch. Zebrane dane podzielono na 12 podgrup obejmujących ejakulaty pobierane w poszczególnych miesiącach roku. Wykazano, że cechy ejakulatów knurów inseminacyjnych zależą od pory roku pobrania. Ejakulaty pozyskiwane w okresie jesienno-zimowym cechują się dużą objętością i zawierają najwięcej plemników o ruchu postępowym. Ejakulaty te cechują się także relatywnie dużą ruchliwością plemników. Ma to związek z dużą liczbą dawek inseminacyjnych wytwarzanych z ejakulatów pobieranych w tym okresie. Ejakulaty pobierane w okresie lata (czerwiec–sierpień) zawierają mniej plemników wykazujących prawidłowy ruch. Uzyskuje się z nich o około 3 dawki inseminacyjne mniej niż z ejakulatów pobieranych w okresie zimowym.

Effect of the backfat thickness at point P2 during insemination on the selected parameters of colostrum and milk of the sows. The studies included 32 females F1 (PL x PLW), inseminated with the semen from Duroc boars. The females were assigned to two groups: L – “lean” sows: P2 ≤18 mm at mating (n=16 heads) and F – “fat” sows: P2 >18 mm (n=16 heads). The observations were carried on from the day of effective mating /insemination throughout the period of gestation and nutrition until weaning (35 day of lactation). Fatness of the sows (measurements of backfat thickness at points P2 and P4) and their muscling (height of M. longissimus dorsi at point P4M) at mating and in high pregnancy (104±1-2 day of gestation) were controlled. The samples of colostrum and milk were collected from all sows (64 samples in total). Basic chemical compositions, somatic cell count – SCC and active acidity – pH, were determined. Thickness of backfat at point P2 did not have any influence on chemical composition of colostrum and milk, SCC and pH; in spite of it. The control of the sows’ condition is justified as there was indicated a significant difference (P≤0.05) in the content of lactose (21. day) in favour of group F vs. L (0.56 pp). The mentioned result indicates the need of continuing the studies because lactose is a valuable, easily assimilated component of mother feed for the newborns.

This investigation aimed to study the effect on fertility parameters of one or two artificial inseminations (AI) and the administration (carazalol) before insemination of β-adrenoceptor blocker in Awassi sheep. A total of 144 Awassi sheep with their oestrous synchronized were divided into 4 groups. Group A1 had a single artificial insemination applied at 52 hours after (the sponge was removed), group A2 had a single artifical insemination applied while for preinsemination 0.01 mg/kg carazalol were given i.v. Group B1 had artificial insemination appled twice at 52 and 60 hours. B2 group had artificial insemination appled twice at 52 and 60 hours and for preinsemination 0.01 mg/kg carazalol were given i.v. As a results, the ratios of not observed oestrus after 25 days were 55.6%, 61.1%, 63.9% and 69.4% in groups A1, A2, B1 and B2 respectively. The ratios of pregnancy were diagnosed ultrasonographically after the 30th day of artificial insemination as 47.2%, 50.0%, 52.8% and 61.1% in groups A1, A2, B1 and B2 respectively. The ratios of birth by means of artificial insemination were 41.7%, 47.2%, 47.2% and 55% in groups A1, A2, B1 and B2 respectively. The degree of fertility was found to be higher in the group in which the sheep applied artificial insemination twice with 8 hours intervals and administrated β-adrenoceptor blocker preinsemination. However, the difference between groups was not significant (p>0.05).
