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 ... -
Egg Quality Characteristics in Autochthonous Genotypes of Chickens Raised on Macedonian Rural Farms
Egg quality characteristics of three different autochthonous chicken phenotypes (phenotype having ashy-silvery-brown leghorn laced plumage color, phenotype having light brown spangled plumage color and phenotype having ... -
Electrophoretic Distinction of the Origin in Different Dairy Products and Milk Samples
Caseins, lacto-albumin, and lacto-globulin are major milk proteins. These globular proteins could be significant indicators of the milk and dairy products origin. Knowing that caseins, lacto-albumins and lacto-globulins ... -
Endocrine Disruption by Heavy Metals on Steroidogenesis in Model Systems
In this study human adrenocortical carcinoma cell line NCI-H295R was used as an in vitro biological model to study the effect of heavy metals on steroidogenesis. The cell cultures were exposed to different concentrations ... -
The Energy Value and Energy Yields of Alfalfa Forage Depending on the Cutting Time in Forage-Seed Production System
Economic importance of alfalfa (Medicago sativa L.) is reflected in the production of high-quality forage, however, the seeds of alfalfa are valuable commodity in the domestic and international markets. In Serbia, the seed ... -
Esophagogastric Ulcer in Pigs on Commercial Farms
Intensive swine production in modern conditions of breeding and use of technological processes has influenced the occurrence of wide range of breeding and technopathy diseases. One of the most abundant breeding diseases ... -
