Pre-calving intravaginal administration of lactic acid bacteria reduces metritis prevalence and regulates blood neutrophil gene expression after calving in dairy cattle
(Frontiers Media, 2018-06-21)
Metritis affects up to 40% of dairy cows and it is usually treated with antibiotics. In
spite of their advantages, there is an increased concern about antibiotic resistance
leading to the research of ...
Skeletal muscle metabolomics and blood biochemistry analysis reveal metabolic changes associated with dietary amino acid supplementation in dairy calves
(Springer Nature, 2018-09-14)
The efects of diferent amino acid (AA) supplementations of milk protein-based milk replacers
in pre-ruminant calves from 3 days to 7 weeks of age were studied. Animals were divided into 4
groups: Ctrl) ...
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 ...
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 ...
Effect of meloxicam and lidocaine administered alone or in combination on indicators of pain and distress during and after knife castration in weaned beef calves
(Public Library of Science, 2018-11-30)
To assess the effect of meloxicam and lidocaine on indicators of pain associated with castration, forty-eight Angus crossbred beef calves (304 ± 40.5 kg of BW, 7–8 months of age) were used in a 28 day ...
Effect of a single dose of subcutaneous meloxicam before knife castration alone or combined with hot-iron branding on scrotal healing, inflammatory response, and behaviour in 2-mo-old beef calves over 42 d post procedure
(NRC Research Press, 2018-08-21)
The objective of this study was to evaluate the effect of a single subcutaneous injection of meloxicam on scrotal healing, inflammatory response, and behaviour in castrated or castrated and branded beef ...
Getting value from the waste: recombinant production of a sweet protein by Lactococcus lactis grown on cheese whey
(BioMed Central, 2018-08-15)
Background
Recent biotechnological advancements have allowed for the adoption of Lactococcus lactis, a typical component of starter cultures used in food industry, as the host for the production of ...
