The authors determined the impact of carcass weight, genotype, sex, and nutrition on the degree of musculature and subcutaneous fattening as well as the level of intramuscular fat in fatteners obtained from market purchase. From among the examined weight groups, carcasses of heavy fatteners were characterized by poorer meatiness, thicker back fat and greater muscle fat content. The evaluation of the examined fattener genotypes revealed a significantly greater fattening of the muscles of crossbreds with 50% proportion of boars of the Duroc breed and purebred pigs than three- and four-breed fatteners obtained using Hampshire and Pietrain breeds. The investigations confirmed better musculature and lower fat content of gilts in comparison with hogs. Moreover, the performed experiments also showed a significant influence of traditional feeding on the reduction of meatiness and increased fattening in comparison with the animals which were fed Grower and Finisher mixtures.

Effect of dehelminthization on milk yield and milk composition in dairy cows. The aim of this study was to assess the effectiveness of action of selected antiparasitic preparation on milk productivity of cows and milk composition. In coproscopic analyses the qualitative methods by Willis, Żarnowski and Josztowa were used, as well as the quantitative McMaster method. A preparation containing eprinomectin was used for dehelminthization. The study involved100 females after first lactation, which were divided into 2 groups 50 head each: experimental (D) - dewormed in May 2 weeks before going to pasture, control (K) – not dewormed. From the experimental group 15 animals were selected (D1) which were dewormed 2 days before parturition. Analogous group of cows (K1) was selected from the control group (at the same stage of lactation, but not dewormed). It was proved that eprinomectin has a positive effect on milk yield, fat level and dry matter in milk, whereas the effect of this preparation on protein content was not confirmed. It was found that the most favorable time of deworming cows is perinatal period.

Celem badania było porównanie wpływu 4 rodzajów tłuszczów spożywczych (margaryny ze stanolami, masła, oleju słonecznikowego, margaryny miękkiej) oraz diety hodowlanej na wybrane parametry lipidowe: cholesterol całkowity (TC), triacyloglicerole (TG), cholesterol we frakcji HDL (c-HDL) i LDL (c-LDL) w osoczu szczurzym. Rodzaj i poziom tłuszczu w diecie nie miały istotnego wpływu na wskaźnik wydajności wzrostowej oraz stężenie cholesterolu we frakcjach HDL i LDL w grupach karmionych dietami wysokotłuszczowymi. Natomiast zastosowane diety wpłynęły różnie na stężenie cholesterolu całkowitego i triacylogliceroli w badanych grupach zwierząt.
