Improved reproductive management allowed dairy cow pregnancies to be optimized for beef production. The objective of this sire-controlled study was to characterize effects of maternal genetics and the dairy management system on calf growth. Pregnancies were created with a 2 × 2 ...
Dairy calf fecal microbiota changes over the first 10 weeks of life. a The diet, sampling, and sequencing scheme for dairy calves (n = 22). TMR indicates a total mixed ration diet. b Boxplots of alpha diversity as measured by Chao1 richness and Shannon diversity index. The Chao1 ...
ArticleOpen access24 June 2024 Background Anthropogenic greenhouse gas emissions have already raised global temperatures by a mean of 1°C above pre-industrial levels, with annual emissions continuing to rise, so slowing global warming is a huge global challenge [1]. Sectors including agriculture, f...
These collectivities are: the calf collectivity and the problem of immunodeficient life; the milking cow collectivity and the problem of ‘stoic’ life; the dry cow collectivity and the problem of fatigued life. In conclusion we point to: the uneven effects for animal-human relationships of ...
Dairy beef productionPastureProfitabilityThe objectives of the current study were to investigate the effects of production system on Holstein-Frisian bulls and steers and also to evaluate the profitability and greenhouse gas (GHG) emissions of these production systems. Calves were assigned to one of ...
The EBI centres on selection for a balance of traits which include production, reproduction, health, and beef. In the future selection based on the EBI will also include direct sustainability type traits like greenhouse gas emissions and nitrogen use efficiency. Delaby et al. [30], in a ...
In this respect, it is interesting to compare our results with a study of fertility in beef heifers which measured transcriptional profiles in white blood cells collected at the time of insemination [158]. Their analysis revealed 18 DEG between heifers which did or did not conceive. ALAS2, ...
Remember, the current Secretary of Agriculture, Tom Vilsack, canceled the July 2024 mid-year All Cattle and Calf Inventory, so the industry won’t get a look at dairy and beef numbers until the end of January 2025. In the East and Mideast, October’s milk production was generally steady ...
Flavour is composed principally of the sensations of smell and taste, although the senses of sight, touch and hearing interact with those of smell and taste. Whereas the sense of taste is relatively simple, having only four modalities, bitter, salt, sour
