The Effect of Supplementation on Selenium and Zinc Content in Blood and Milk of Dairy Cows
Milk is an important source of microelements for calves during the suckling period as well as in human nutrition. Concentration of trace elements in blood and their secretion via milk can significantly change depending on ... -
The Effect of Addition of Lucerne Biomass and NPN Substances on Quality of Grape Pomace Silage
Grape pomace (GP) of white varieties without stalks was ensiled by the method of single factor trial in the two treatments: in the first treatment, with the addition of lucerne biomass (L) of the last cut, which was harvested ... -
Effect of Applied Pmsg Dose on Reproductive Parameters for Improved Sjenica Sheep in Anestrous Season
This paper shows the results of the effects of higher dose 700 i.u. of natural gonad tropic hormone PMSG application in comparison with usual 500 i.u dose which is used at the farms during the induction and synchronization ... -
Effect of Carbohydrate Source and Addition Canola Seed on Growth Performance and Nutrient Digestibility of Lambs
The objective of this study was to investigate effects of partial replacement of starch with neutral detergent soluble fiber with or without roasted canola seed as a fat source, and possible interactions on apparent ... -
Effect of Consecutive Cut and Vegetation Stage on Cncps Protein Fractions in Alfalfa (Medicago Sativa L.)
Crude protein (CP) of forages can be separated into fractions of differentiated abilities to provide available amino acids in the lower gut of ruminants. This knowledge is critical to develop feeding systems and to predict ... -
Effect of Different Levels of Lavandula Stoechas Essence on Production Performance and Egg Quality of Laying Hens
The objective of this study was to evaluate the effects of different levels of Lavander stoechas essence on performance and egg quality of laying hens for 8 weeks. This experiment was conducted with 160 Hy-Line (W36) laying ... -
Effect of High Levels of Ammonia in Air on Adrenal Response to Adrenocorticotropin and Forced Running in Rabbits
The aim of the present study was to assess adrenal response to high air ammonia levels in rabbits. Twenty male rabbits of the New Zealand White breed at the age of 4 months were randomly allocated into two groups: control ... -
The Effect of Hive Volume on Efficiency and Strength Conservation and Restoration of Food Supplies During the Wintering in Langstroth Hives
The influence of volume of the hive on wintering, colony strength and food supply was observed during the three-year period. Standard LR hives were used for the experiment. Colonies were tested based on the number of hive ... -
Effect of Rapeseed Meal as Protein Supplement in Feedlot Lamb Diets on Excretion of Urinary Purine Derivates and Microbial Protein Synthesis
The objectives of our work were to establish the feeding effects of rapeseed meal (RSM) on urinary purine derivatives (PD) excretion as an indicator of ruminal synthesized and yielded microbial crude protein (MCP), and ... -
The Effect of Raw Soybeans in Mixtures for Laying Hens on Egg Quality and Egg Shell Quality
The study was conducted on hens at the age of 49 - 57 weeks to identify opportunities for replacing, with raw grain, thermally processed soybean Lana variety with a reduced level and Lydia variety with a standard level of ... -
Effect of Rooster Macrophages on the Motility Characteristics of Spermatozoa
The aim of our study was to detect macrophages in rooster semen and subsequently to asses their effect on the spermatozoa motility parameters. Semen samples were collected from Ross PM3 breeder males (n = 24) by the ... -
The Effect of the Use of Sexed Semen on Reproductive Traits and Sex Ratio of Black and White Calves
Sperm sexing is a relatively new biotechnological procedure which offers us the possibility to choose the offspring sex. This method is widely used today in the insemination of the dairy cattle breeds and it is based on ... -
Effect of Vitamin E, Lutein, Selenium and Oil Mixture Added to Feed and Cooking Length on Yolk Color and Egg Quality
The aim of this research was to determine the quality of eggs laid by Tetra SL hens fed standard diet (B) or diet supplemented with 100 mg vitamin E/kg+200 mg/kg lutein+0.5 mg/kg selenium+5% oil mixture (BK). The effect ... -
Effects of Cadmium on Rumen Fermentation and Nutrient Digestibility Using Dual Flow Continuous Culture System
This experiment was conducted to investigate the effects of different doses of cadmium on fermentation characterization and nutrient digestibility using dual flow continuous culture system. Eight dual-flow, continuous ... -
Effects of Inorganic and Organic Selenium Supplementation on Blood and Milk Selenium Concentration in Dairy Cows
Selenium is an important trace element in the nutrition of dairy cows because it prevents oxidative damages of tissue and in that way protects the animals from the incidence of various disorders. Addition of various levels ... -
Effects of Phytogenic Feed Additive and Enzyme on Growth Performance of Broilers Fed Diets with Reduced Energy Concentrations
The effects of dietary supplementation with phytogenic feed additives (PFA) and enzyme (E) on performance parameters were investigated using Ross 308 as hatched broilers fed standard diets or diets with reduced energy ... -
