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 ...
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 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 ...
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 ...
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 ...
Immunomodulation Evidence of Nanostructured Recombinant Proteins in Salmonid Cells
(MDPI, 2024-03-09)
Recent studies have demonstrated that immune-related recombinant proteins can enhance immune function, increasing host survival against infectious diseases in salmonids. This research evaluated inclusion ...
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 ...
Complete feed versus concentrate and straw fed separately: Effect of feeding method on eating and sorting behavior, rumen acidosis, and digestibility in crossbred Angus bulls fed high-concentrate diets
(Elsevier, 2021-01-06)
The aim of this study was to evaluate the effect of feeding method on eating and sorting behavior, rumen acidosis, and apparent total tract digestibility of crossbred Angus bulls fed a high-concentrate ...
The relationship between feed efficiency and behaviour differs between lactating Holstein and Jersey cows
(Cambridge University Press, 2023-08-24)
In dairy production, high feed efficiency (FE) is important to reduce feed costs and negative impacts of milk production on the climate and environment, yet little is known about the relationship between ...
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 ...
