It was hypothesized that dietary polyphenol-rich fruit pomaces can improve the antioxidant status of both diets and the tissues of turkeys fed such diets. Turkeys were fed diets containing a cellulose preparation (C) or 5% dried apple pomace (AP), blackcurrant pomace (BCP), strawberry pomace (SP) and seedless strawberry pomace (SSP). Blood and liver biochemical parameters were determined in 7 birds...
The goal of the experiment was to specify the impact of glycerides of medium-chain fatty acid (AveMix MCT) additives and a herbal additive (AdiSan) on production results in turkeys. The research material covered 160 BIG-6 turkeys (hens) divided into 2 groups, 4 series in each group. The experiment lasted 15 weeks. The control group received compound feed, without additives, of organicacids and herbs...
The aim of the study was to determine changes in nitrogen fractions during the ensiling of lucerne and red clover herbage in bales. Protein nitrogen and non-protein nitrogen compounds in herbage and silage were distinguished. Furthermore, buffer soluble nitrogen compounds (BSN) were determined and divided into buffer soluble protein and non-protein nitrogen (BSPN and NPBSN, respectively). In addition,...
The objective of this study was to determine the effect of dietary supplementation with a blend of organic acids, zinc oxide and the B-Safe® herbal product on nutrient digestibility, nitrogen balance and growth performance in weaned piglets. Nutrient digestibility was determined by a simple balance method, on 24 weaners (PIC) with average body weight of 28 kg, divided into four groups of six animals...
The effect of different dietary levels of selenium (Se) and vitamin E on egg production, the antioxidant status and the immune system response of hens was investigated in the current study. A total of 32 Lohman Brown hens were divided into four groups and were fed diets with 5% of soybean oil and two levels of Se (0.15 and 0.30 mg/kg) and vitamin E (30 and 60 mg/kg). During 10 weeks of experimental...
The experiment was conducted on 26 nursing Kamieniec ewes from a breeding herd. The animals were divided into two equal groups characterized by the same litter type, age and sex of suckling lambs: I - control and II - experimental. Throughout the 70-day lactation period, both groups were fed identical diets comprising haylage of grasses and legumes, meadow hay and CJ concentrate in daily rations of:...
The objective of this study was to determine the effect of yeast preparations on selected properties of meat from suckling lambs. The experiment was conducted on 30 Kamieniec rams divided into three groups: I - control, II and III - experimental. Throughout the 100-day rearing period, the experimental animals were fed diets supplemented with Saccharomyces cerevisiae prebiotics: Inter Yeast S® brewer's...
