Lactose is the main carbohydrate in mammals' milk, and it is responsible for the osmotic
equilibrium between blood and alveolar lumen in the mammary gland. It is the major bovine …

Dairy cow longevity is an essential economic trait that can supplement the breeding value of
production traits, which is related to the herd time and lifetime milk yield of dairy cows …

The increasing lactational performance of dairy cows over the last few decades is closely
related to higher nutritional requirements. The decrease in dry matter intake during the …

The objective of this research was to estimate heritabilities of milk urea nitrogen (MUN) and
lactose in the first 3 parities and their genetic relationships with milk, fat, protein, and SCS in …

Lactose percentage (LP) in milk is currently determined in most herd-testing schemes, and
globally, it is usually routinely recorded in the framework of the official milk recording …

The genetic correlations (ra) of milk lactose percentage (LP), lactose yield (LY), and ratios of
LP to other milk solids with udder, metabolic, and fertility disorders have not been assessed …

In this study, cow reticulorumen content pH and temperature together with the activity were
registered using smaXtec boluses, specially designed for animal care. Body weight …

At the beginning of lactation, high-producing cows commonly experience an unbalanced
energy status that is often responsible for the onset of metabolic disorders and impaired …

The main objectives of this study were to estimate genetic parameters for milk urea nitrogen
(MUN) in Holstein cattle and to conduct a single-step (ss) GWAS to identify candidate genes …

Lactose is a major component of milk (typically around 5% of composition) that is not usually
directly considered in national genetic improvement programs of dairy cattle. Daily test-day …
