Relationship between biochemical analytes and milk fat/protein in Holstein cows

Austral Journal of Veterinary Sciences, 2019
The aim of this study was to assess the relationship between biochemical analytes and milk fat/protein in high-yield (DIM: 42 ± 10 d postpartum) and low-yield (DIM: 91 ± 11 d postpartum) Holstein cows.

Milk production, fluid balance and temperature regulation in lactating camels (Camelus dromedarius) [PDF]

, 2010
The aims of this thesis were to identify good milking and watering routines for camels, and to better understand the physiological mechanisms that enable camels to produce milk during long periods of water deprivation.

Conjugated linolenic acid (CLnA), conjugated linoleic acid (CLA) and other biohydrogenation intermediates in plasma and milk fat of cows fed raw or extruded linseed [PDF]

, 2007
Thirty lactating dairy cows were used in a 333 Latin-square design to investigate the effects of a raw or extruded blend of linseed and wheat bran (70:30) on plasma and milk fatty-acids (FA).

The influence of eating and rumination time on solids content in milk and milk yield performance of cows

, 2023
The aim of this study was to evaluate the effect of rumination time, eating time and season on milk yield and on milk component content in the context of milk recording. The experiment was carried out with two breeds - Czech Fleckvieh cattle and Holstein

The effect of milking frequency on milk yield and milk composition in ewes

Czech Journal of Animal Science, 2020
Milking frequency is the main factor regulating milk yield and milk quality if feeding, welfare, health, and environmental conditions are adequate. Milk yield and composition are substantially influenced by breed, and consequently the breed has an impact

A covariance function for feed intake, live weight and milk yield estimated using a random regression model [PDF]

, 1999
To enable investigation of genetic variation during early lactation in heifers, multitrait covariance functions were used to describe genetic covariances among feed intake, live weight, and milk yield during the first 15 wk of lactation (n = 628). Random
