Wheat grain (WG) is unique in possessing extensive starch and nitrogen fermentation (i.e. >85% in ground and steam-processed WG), low cation–anion difference and high-intake properties, making it a potentially useful prepartal dietary choice. The o

24 Holstein cows and 16 Holstein heifers in close-up period were used to evaluate the effects of ground wheat grain in prepartum diets on health and performance of dairy cows. Cows were blocked based on parity (three groups) and then randomly assigne

Simple Summary The positive effects of nucleotide (NU) supplementation in milk replacer have been elucidated in infants and partly in dairy calves; however, NU addition to whole milk has not been evaluated yet. In this study, a NU-containing suppleme

Our initial hypothesis was that the exogenous supply of nucleotides to neonatal calves would improve the development and functionality of gastrointestinal tissue, thereby enhancing their capacity to efficiently digest and utilize the nutrients in hig

Performance of female Holstein calves (n = 60) were evaluated in three step-down milk feeding programmes: step-down 1 (STP1: 7.5 litres/day milk from days 1 to 21, 6 litres/day milk from days 22 to 42, 4 litres/day milk from days 43 to 63 and 2 litre

It is commonly believed that ruminants exposed to sunlight, and consequently heat stress (HS), consume more concentrate and lower forage, but there is limited evidence on this issue. The objective of this study was to determine the productivity and v

To evaluate the effect(s) of the heat stress (HS) on body composition thirty-two growing Afshari lambs were randomly housed outdoor (OUT) without access to shade (mean temperature humidity index = 74.98) or kept indoor (IN) under shade (mean temperat

This research communication describes relationships between pre-weaning average daily gain (ADG) and dam parity with future productivity of dairy calves. Higher ADG before weaning has been shown to be related to greater milk production in the first l

Prepartum milk leakage happens in some pregnant dairy cows close to calving. It has been hypothesized that low blood Ca is a cause of this event. To investigate the possible reason(s) of milk leakage, 137 multiparous pregnant Holstein cows were enrol
