Benefits of barley straw as a forage for dairy calves before and after weaning
(Elsevier, 2023-08-07)
The aim of this study was to assess the potential consequences on calf intake, performance, behavior, ruminal microbiome, and ruminal epithelium development of combining the inclusion of chopped barley ...
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 ...
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 ...
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 ...
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 ...
Prevalence and lameness-associated risk factors in Alberta feedlot cattle
(Oxford University Press, 2019-03-13)
Lameness in cattle is a health and welfare concern; however, limited information is available on risk factors and the relationship between lameness and common diseases like bovine respiratory disease ...
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 ...
