Studies of Autumn calving suckler cows, bulls at pasture and winter grazing [PDF]
, 2010 End of project reportMost beef and dairy cows are spring calving leading to distinct seasonality of supply. Calving a proportion of the beef herd in the autumn would lead to a more uniform annual supply of cattle for slaughter and potentially increase ...

Hot spots or hot moments? Contextualizing the spatio‐temporal scale of research on animal inputs
Ecography, EarlyView.Mammals play important roles in redistributing elements across ecosystems, concentrating biogeochemical inputs across both space and time. However, research on zoogeochemical inputs is often constrained by logistical considerations, potentially limiting our knowledge of mammals' impacts on biogeochemical patterns and processes.

Earlier calves are heavier calves
California Agriculture, 1969 CATTLEMEN HAVE OBSERVED that calves dropped early in the calving season arc heavier at weaning and more profitable than calves dropped late in the calving season. Animal scientists have pointed out that weaning weight is the result of age at weaning and average daily gain from birth to weaning.

An empirical analysis of the cost of rearing dairy heifers from birth to first calving and the time taken to repay these costs [PDF]
, 2017 Rearing quality dairy heifers is essential to maintain herds by replacing culled cows. Information on the key factors influencing the cost of rearing under different management systems is, however, limited and many farmers are unaware of their true costs.

Comparative analysis of microRNAs in bovine colostrum and neonatal calf blood
Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND MicroRNAs (miRNAs) are short non‐coding RNAs that participate in a wide range of biological processes. MiRNAs are present in high concentrations in colostrum, and these may be potentially transferred to newborn calves being fed colostrum.

Relationships Among Beef Cow Productivity Traits and Single Nucleotide Polymorphisms in the Bovine Heat Shock Protein 70 Gene [PDF]
, 2018 When eukaryotes are exposed to stressors such as heat, toxins, and low oxygen levels, heat shock proteins (HSPs) are synthesized to maintain normal cellular function within the body.

Oral supplementation of medium-chain fatty acids during the dry period supports the neutrophil viability of peripartum dairy cows [PDF]
, 2013 A randomised clinical trial was conducted to explore the effect of orally supplemented medium-chain fatty acids (MCFA) to heifers and cows starting 6-8 weeks prior to expected calving date on blood and milk polymorphonuclear neutrophilic leucocyte (PMNL)

Evaluation of Level of Milk Potential on Nutrient Balance in 2- and 4- Year- Old May- Calving Range Cows Grazing Sandhills Upland Range [PDF]
, 2020 A modeling study evaluated the effects of milk production level on nutrient balance in May- calving cows grazing Sandhills upland range during the breeding season. Forage quality of upland range peaks in June and steadily declines in July until November.
