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 ...
The Potential of Metalloproteinase-9 Administration to Accelerate Mammary Involution and Boost the Immune System at Dry-Off
(MDPI, 2021-11-30)
The dry period is decisive for the milking performance of dairy cows. The promptness of
mammary gland involution at dry-off affects not only the productivity in the next lactation, but also
the risk ...
Changes in the rumen and colon microbiota and effects of live yeast dietary supplementation during the transition from the dry period to lactation of dairy cows
(Elsevier, 2019-05-02)
The first objective of this study was to evaluate the dynamics and their potential association with animal performance of the microbiota in both the rumen and colon of dairy cows as they move from a ...
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 ...
Simulation of feed restriction and fasting: Effects on animal recovery and gastrointestinal permeability in unweaned Angus-Holstein calves
(Elsevier, 2022-01-25)
Feed restriction and fasting experienced during commercial production negatively affect unweaned calves' behavior and health status. Transportation and stays at assembly centers are the main factors ...
Correlation between L-Lactate Concentrations in Beef Cattle, Obtained Using a Hand-Held Lactate Analyzer and a Lactate Assay Colorimetric Kit
(MDPI, 2021-03-25)
Lactate is a product of anaerobic glycolysis, used in animal research as an indicator of muscle fatigue. Therefore, it has been used as an indicator of cattle response to long distance transportation. ...
Short communication: A milk replacer aversion model in calves to test flavour-masking effects
(Elsevier, 2022-01-18)
This study aimed to evaluate the availability of two sensory additives (SAs) to masque non-palatable ingredients commonly present in milk replacers (MRs). Both SAs were based on a synergistic mixture ...
A Meta-analysis Describing the Effects of the Essential oils Blend Agolin Ruminant on Performance, Rumen Fermentation and Methane Emissions in Dairy Cows
(MDPI, 2020-04-03)
There is an increasing pressure to identify feed additives which increase productivity or decrease methane emissions. This paper aims to elucidate the effects of supplementing a specific essential oils ...
Effect of a single subcutaneous injection of meloxicam on chronic indicators of pain and inflammatory responses in 2-month-old knife and band-castrated beef calves housed on pasture
(Elsevier, 2020-10-19)
One hundred and thirty-one 2 mo. old pasture housed Angus cross bull calves were evaluated for 62 d over two years (Year 1: n = 69, 134.1 ± 20.37 kg BW; Year 2: n = 62, 118.1 ± 15.49 kg BW) to determine ...
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 ...
