Short communication: Performance, intestinal permeability, and metabolic profile of calves fed a milk replacer supplemented with glutamic acid
(American Dairy Science Association, 2019-11-13)
The objective of this study was to evaluate the potential benefits of supplementing glutamic acid in milk replacers (MR) with respect to calf performance, intestinal permeability, and metabolism. Sixty ...
Effect of particle size of a mash concentrate on behavior, digestibility, and macroscopic and microscopic integrity of the digestive tract in Holstein bulls fed intensively
(Oxford University Press, 2018-11-01)
Twenty-four individually housed Holstein bulls (456 ± 6.9 kg of body weight and 292 ± 1.4 d of age) were enrolled in a complete randomized experiment involving four dietary treatments to evaluate the ...
Trends in recombinant protein use in animal production
(BMC, 2017-03-04)
Recombinant technologies have made possible the production of a broad catalogue of proteins of interest, including those used for animal production. The most widely studied proteins for the animal sector ...
A new approach to obtain pure and active proteins from Lactococcus lactis protein aggregates
(Nature Research, 2018-09-17)
The production of pure and soluble proteins is a complex, protein-dependent and time-consuming
process, in particular for those prone-to-aggregate and/or difcult-to-purify. Although Escherichia coli ...
Whole rumen metagenome sequencing allows classifying and predicting feed efficiency and intake levels in cattle
(Nature Research, 2019-01-09)
The current research was carried out to determine the associations between the rumen microbiota and traits related with feed efficiency in a Holstein cattle population (n = 30) using whole metagenome ...
Lactating performance, water and feed consumption of rabbit does reared under a Mediterranean summer circadian cycle of temperature v. comfort temperature conditions
(Elsevier, 2015-01-16)
The general aim of this research was to study the effect of high ambient temperature on the performance of does during lactation, specifically the following factors: average daily feed (ADFI) and water ...
Skeletal muscle metabolomics and blood biochemistry analysis reveal metabolic changes associated with dietary amino acid supplementation in dairy calves
(Springer Nature, 2018-09-14)
The efects of diferent amino acid (AA) supplementations of milk protein-based milk replacers
in pre-ruminant calves from 3 days to 7 weeks of age were studied. Animals were divided into 4
groups: Ctrl) ...
Trans-Generational Effect of Maternal Lactation during Pregnancy: A Holstein Cow Model
(Public Library of Science, 2012-12-20)
Epigenetic regulation in mammals begins in the first stages of embryogenesis. This prenatal programming determines, in
part, phenotype expression in adult life. Some species, particularly dairy cattle, ...
Feeding pasteurized waste milk to preweaned dairy calves changes fecal and upper respiratory tract microbiota
(Frontiers Media, 2019-06-06)
In the present study bacterial communities from both, the gastrointestinal and respiratory tract of pre-weaned dairy calves fed two different milk-feeding programs were characterized using 16S rRNA gene ...
Pharmacokinetics of oral and subcutaneous meloxicam: Effect on indicators of pain and inflammation after knife castration in weaned beef calves
(Public Library of Science, 2019-05-24)
Oral meloxicam is labelled for reducing pain and inflammation associated with castration in cattle in Canada, however, subcutaneous meloxicam is only labelled for pain associated with dis-budding and ...
