Effects of Flavonoids Extracted from Citrus aurantium on Performance, Behavior, and Rumen Gene Expression in Holstein Bulls Fed with High-Concentrate Diets in Pellet Form
(MDPI, 2021-05-13)
Flavonoid supplementation may modify the behavior and rumen inflammatory response of fattening bulls, and this could be related to the concentrate presentation (mash or pellet) form. In the present ...
The effects of colostrum consumption and feed restriction during marketing and transportation of male dairy beef calves: Impact on pre-transport nutritional status and on farm recovery
(Elsevier, 2023-08-23)
The aim of this study was to evaluate the effects of colostrum consumption and feed restriction on biomarkers of stress, nutritional and health status, gut functionality, and behavior in male dairy beef ...
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 ...
Short Communication: The biological value of transition milk: analyses of Immunoglobulin G, IGF-I and Lactoferrin in primiparous and multiparous dairy cows
(Elsevier, 2023-05-24)
Colostrum (the first mammary gland secretion after calving) is known to contain high concentrations of nutrients as well as bioactive substances (including immunoglobulins, growth factors, and antimicrobial ...
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 ...
Design strategies for positively charged endolysins: Insights into Artilysin development
(Elsevier, 2023-09-06)
Endolysins are bacteriophage-encoded enzymes that can specifically degrade the peptidoglycan layer of bacterial cell wall, making them an attractive tool for the development of novel antibacterial agents. ...
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 ...
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 ...
