α-Lactalbumin (α-LA) is one of the most abundant milk whey proteins among different mammalian species including domestic horse. The aim of this study was to screen for polymorphism in the 5’-flanking region of the equine α-LA (LALBA) gene and to assess the potential relationship of particular genotypes with LALBA gene expression variability (measured at the mRNA and protein levels) and with basic...
The aim of the study was to assess the quality of colostrum and milk with reproductive performance in sows offered different feed allowances from day 41 to 70 of gestation. In the study 20 F1 sows (Polish Landrace x Polish Large White), 10 animals per group: Control and Experimental, were used. During mid-pregnancy period, sows received 2.3 kg (Control) and 3.0 kg (Experimental) of feed daily. Samples...
Relationship between the parity and oxidative stress in high-performance Polish Holstein-Friesian cows after the peak of lactation. There are many factors, which may expose cows attacks of free radicals. The highest level of oxidative stress appears in the parturition period and at the peak of lactation. Therefore, the purpose of this study was to demonstrate the relationship between the parity and...
Zmienność koncentracji funkcjonalnych kwasów tłuszczowych w mleku w okresie żywienia pastwiskowego krów. Celem pracy było określenie zmienności zawartości funkcjonalnych kwasów tłuszczowych (FFA) oraz zbadanie wartości wskaźnika miażdżycowego (AI) i wskaźnika trombogennego (TI) w mleku krowim w poszczególnych miesiącach sezonu pastwiskowego. Badanie zostało przeprowadzone w gospodarstwie niskonakładowym...
Meat quality of fattening pigs fed yellow lupin-based diets. The 30 crossbred pigs [(Landrace x Yorkshire) x Duroc] were fattened in 3. phase fattening period. In their nutrition as a source of protein was used soybean meal (Group C) or soybean meal and seeds of yellow lupine in the amount of 7.5% (Group E1) and 15% (Group E2). After achieving body weight of about 117.5 kg animals were slaughtered...
Inappropriate doses and quality of dietary nutrients cause problems in providing the protein and energy balance in a feed ration. Especially, energy value of the feed ration poses many problems to dairy cattle breeders and particularly in the perinatal period, which results in increased incidence of metabolic disorders. These disorders are today one of the most frequent causes of culling of dairy...
