Using compositional mixed-effects models to evaluate responses to amino acid supplementation in milk replacers for calves
(Elsevier, 2021-04-15)
The consequences of supplementing Lys, Met, and Thr in milk replacers (MR) for calves have been widely studied, but scarce information exists about potential roles of other AA (whether essential or not). ...
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 ...
Symposium review: Decomposing efficiency of milk production and maximizing profit
(American Dairy Science Association, 2019-12-16)
The dairy industry has focused on maximizing milk yield, as it is believed that this maximizes profit mainly through dilution of maintenance costs. Efficiency of milk production has received, until ...
Effectiveness of precision feeding in reducing N excretion in dairy cattle
(Elsevier, 2023-07-01)
Two periods enrolling 56 (milk yield 36.2 ± 7.91 kg/d) and 58 (milk yield 32.4 ± 4.99 kg/d) grouped-fed dairy cows were performed to evaluate nutrient adjustment and N emissions of a precision feeding ...
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 ...
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 ...
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 ...
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 ...
Consequences of supplying methyl donors during pregnancy on the methylome of the offspring from lactating and non-lactating dairy cattle
(Public Library of Science, 2017-12-11)
The aim of this study was to evaluate the potential effects of methyl donor supplementation of pregnant animals in the presence or absence of a concomitant lactation on the methylome of the offspring. ...
Potential of Oral Nanoparticles Containing Cytokines as Intestinal Mucosal Immunostimulants in Pigs: A Pilot Study
(MDPI, 2022-04-21)
Antimicrobial resistance is a global threat that is worryingly rising in the livestock sector.
Among the proposed strategies, immunostimulant development appears an interesting approach to
increase ...
