The effects of addition of vitamin D(3) and vitamin E to pig diets on blood plasma calcium concentration, meat quality (longissimus muscle) and antioxidative capacity were investigated. Two treatments consisted of supplementation with vitamin D(3) (500,000IU/d) for 5 days separately (group D) and a combination of vitamin E (500mg α-tocopheryl acetate/kg(More)
The effect of dietary n-3 fatty acids on the fatty acid composition and lipid peroxidation of different tissues in pigs were studied. 20 castrated male pigs were included in this investigation, one half was fed daily a diet containing 1.3 g n-3 fatty acids/kg diet (control) and 10 pigs were fed a diet containing 14 g n-3 fatty acids/kg diet (n-3 diet) at(More)
Feeding experiments with diets containing Fusarium toxin-contaminated wheat were conducted to clarify the pathogenesis of enzymatic and histopathological effects of Fusarium toxins on porcine liver cells. A total of 36 prepuberal gilts were divided into four groups and fed diets with increasing proportions of Fusarium toxin-contaminated wheat at a total(More)
The intracellular Ca(2+) concentration is mainly regulated by the sarcoplasmic reticulum (SR). A disturbed regulation leads to an increased metabolism and ultimately to inferior meat quality. In this study, pigs with normal and mutated calcium release channels (referred to as MHR and MHS, respectively) were used. One batch of pigs was slaughtered in winter(More)
The aim of this study was to alter the fatty acid composition of porcine tissue by accumulating essential fatty acids without adversely affecting carcass composition, muscle structure or meat eating quality. A total of 13 female and 12 castrated Pietrain×German Landrace pigs were fed a basal concentrate diet supplemented with 5% olive oil or 5% linseed oil(More)
Seventy eight growing-finishing pigs (male castrates and females) of the cross-breed Pietrain x (Large White x German Landrace) were used to investigate the effects of pST treatment on the chemical composition of the body, the growth of adipocytes, and the fatty acid profile of the backfat. Intramuscular injections (1 or 3 mg pST) were administered daily(More)
Energy balances were measured by indirect calorimetry in four experiments on male growing rats, fed restrictively on isoenergetic and isonitrogenous (10% CP) diets based on either casein supplemented with methionine, or soy protein isolate (experiments 1, 2 and 3) and soy protein isolate supplemented with methionine (experiment 0), respectively. At the end(More)
The effects of an enriched environment on growth, meat quality, and muscle biological traits were investigated using 64 castrated pigs (age range 7 to 20 weeks). Positive emotional appraisal was induced by a system that acoustically frequently called individuals out of a group (n=32) to a feeding station, where they were rewarded with small portions of(More)
Oviductal endosalpingeal cells were mechanically isolated from heifers at different reproductive stages (cyclic: days 8-14, at oestrus: day 0 and pregnant: day 7) and cultured until 100% confluent. The cells were loaded with the Ca(2+)-sensitive fluorochrome fura-2/AM, and cytosolic free calcium ([Ca2+]i) was monitored spectrofluorimetrically and by use of(More)
Wheat contaminated naturally with the Fusarium toxins deoxynivalenol (DON) and zearalenone (ZON) was fed to pregnant Landrace sows for 35days. On day 110, caesarean section was carried out, the offspring were killed immediately after birth, and their livers and spleens examined. At necropsy there were no macroscopic lesions observed in any organ of either(More)
