Maternal influences on oral and faecal microbiota maturation in neonatal calves in beef and dairy production systems

Animal Microbiome, 2020
Background The dam is considered an important source of microbes for the calf; consequently, the development of calf microbiota may vary with farming system due to differences between the contact the calf has with the dam. The objective of this study was

Effects of processing sorghum grain on dairy calf performance

Kansas Agricultural Experiment Station Research Reports, 1994
Two trials evaluated the effect of sorghum grain processing on dairy calf performance. In trial 1, Holstein calves (n = 76; .5 to 8 wk of age) were fed one of three calf starters that contained either raw, roasted (exit temperature of 135 degrees C), or conglomerated sorghum grain.

Evaluation of Multi‐Breed Genomic Prediction Models for Carcass and Reproductive Traits in Zebu Beef Cattle

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Genomic prediction in beef cattle is particularly challenging in breeds with limited phenotypic and genotypic data. In this context, multi‐breed methodologies that integrate information from genetically related populations have emerged as a promising strategy to improve prediction accuracy and calibration under data‐scarce conditions.

‘Becoming With’ on the Dairy Farm: A Post‐Humanist Inquiry Into More‐Than‐Human Socialisation and Agency

Sociologia Ruralis, Volume 66, Issue 4, October 2026.
ABSTRACT Literature has described dairy cows as both passive objects and active participants in the milk production process. This study explores how this passivity and activity co‐exist through an inquiry into dairy cow agency within a post‐anthropocentric conceptualisation of socialisation theories.

Effects of Prenatal Ursodeoxycholic Acid and Probiotic Supplementation on Stress Parameters, Immune Response and Lamb Survival Rates in Ewes

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Prenatal ursodeoxycholic acid (UDCA) and probiotic supplementation, administered alone or combined, modulate colostrum quality and neonatal immunity in ewes. Combined UDCA + PRO most consistently increases colostral IgG, enhances neonatal IgG levels, and improves lamb survival.
