Use of hop cones in growing beef cattle nutrition. The objective of this study was to determine the effect of the supplementation of bull diets with hop cones on growing bull performance, the concentrations of blood analytes, including liver enzymes. Twenty-four growing bulls of Slovene autochthonous Cika breed (BW 373 kg; age 329 days) were randomly allocated to 6 pens (4 animals/pen). Before the...
Effect of liquid acidifiers on rearing performance of suckling piglets.Crossbred piglets from 36 litters (12 litters each in control group C and in experimental groups E1 and E2) were investigated. From birth to weaning at 28 days of age, piglets from group E1 received drinking water with a 2% solution of lactic, formic and orthophosphoric acids, and those from group E2 a 0.05% solution of Baracid...
Effect of dietary arginine supplementation on body weight changes and productivity of sows.The objective of this study was to determine whether provision of additional arginine to pregnant and lactating sows could influence body weight changes in females during reproductive cycle as well as reproductive and rearing performance of the piglets. The study included 36 F1 crossbred sows (Polish Landrace...
Nutrition plays a key role in the maintenance of animal reproductive performance. Reduced reproductive efficiency can decrease the profitability of dairy production by increasing days open, calving interval, the number of services per conception, culling rate, and veterinary services. Nutritional requirements increase rapidly with milk production after calving, but an improper diet plan could result...
The results of studies conducted so far in the field of supplementing Se deficiency in cow and goat diets demonstrate unequivocally the positive influence of supplements used on the improvement of the health status of animals and an important increase in the concentration of this microelement in the obtained milk. The positive influence on health is reflected in the increased antioxidative status...
The purpose of the work was to determine the effect of the fi bre content in the mixture on morphometric traits of intestinal epithelium of fatteners. In one-phase fattening, 14 crossbred pigs were classifi ed into two groups and ad libitum fed the mixtures, differing in the composition and nutritional value, including the level of crude fi bre (control group – C – 3.4%; experimental group – E – 12%)...
