β-Lactoglobulin (β-LG) is the dominant non-casein whey protein found in milk of bovine and of most ruminants. The amino acid sequence of β-LG along with its 3-dimensional structure illustrates linka...
The aim of this study was to determine the impact of the length of calf sucking milk from its own mother on calf growth at the age of 3 months and milk yield of mothers. We tested a hypothesis that th...
Four high-yielding lactating Holstein cows fitted with duodenal cannulas were used in the experiment. Cows were divided into 2 groups – control (Control) with leucine deficiency and experimental (Leuc...
The objective of this study was to analyze the relationships among cows’ body condition score before calving, subsequent BCS changes, milk yield, lactation characteristics and their sires’ relative br...
The objective of this study was to confirm the relationship among body condition score at the time around parturition, milk yield in subsequent lactation, reproductive efficiency and BCS development i...
The objective of this study was to determine how non-nutritional factors such as herd, parity, days in milk, milk production, and milk components affect the concentration of milk urea. A retrospective...
An experiment was performed on 37 Holstein-Friesian cows during the first 120 days of lactation. The cows were fed balanced diets composed of haylage and maize silage (together 52% dry mater) and a co...
To evaluate the forage effects on performance and metabolic parameters, 24 Holsteins were randomly fed one of the diets containing a forage mixture with majority of alfalfa hay (AH), alfalfa silage (A...
The aim of the paper was to prove the accuracy of various statistical models of vari璦nce analysis for estimation of systematic factors that influence milk yield and fat and protein content in dairy go...
The aim of this modelling study was to investigate the effect of large herd size (and land areas) on walking distances and milking interval (MI), and their impact on milk yield and economic penalties ...
To evaluate the effects of feeding linseed oil or/and sunflower oil mixed with fish oil on milk yield, milk composition and fatty acid (FA) profiles of dairy cows fed a high-concentrate diet, 24 cross...
The present study was carried out to evaluate the effects of ensiled mixed apple pomace and broiler litter (EAPBL) on milk yield (MY) and composition, dry matter intake (DMI) and blood parameters at e...
Four crossbred (75% Holstein Friesian) lactating dairy cows, with an average live weight of 418±5 kg and 36±10 d in milk were randomly assigned according to a 2×2 factorial arrangement in a 4×4 Latin ...
This review focuses on the nutritional effects from birth until age at first calving on growth, mammary developmental changes, and first-lactation milk yield in heifer calves. The advancement in the g...
This study was conducted to determine the nutritive value of live yeast culture (RumiSacc, Saccharomyces cerevisiae) and to investigate its effects on milk yield, milk composition and some blood param...
