Evaluating pasture forage plant breeding achievements: a review

New Zealand Journal of Agricultural Research, Volume 68, Issue 6, Page 1146-1220, December 2025.
ABSTRACT Forage plant breeding aims to deliver cultivars that increase on‐farm productivity through improved seasonal and annual yield, persistence of yield in perennials, and nutritive and feeding value. Breeding is generally undertaken in highly controlled field trials with individual plants or rows.

Rumen Epithelial Transcriptome Analysis Revealed the Regulatory Mechanism of Host Adaptation to Nitrogen Source Replacement Diet in Simmental Cattle

Food Science &Nutrition, Volume 13, Issue 10, October 2025.
The findings of this study suggest that urea replacement of some soybean meal feeding activates compensatory mechanisms in the rumen epithelium to maintain homeostasis of the organism through dynamic changes in intercellular junctions and adaptive up‐regulation of metabolic pathways.

Exploring Two Different Feeding Strategies During Dry Period With Regard to Dry Matter Intake, Intermediary Metabolism and Certain Health Aspects of Dairy Cows in Germany

Journal of Animal Physiology and Animal Nutrition, Volume 109, Issue 5, Page 1073-1090, September 2025.
ABSTRACT Dry cow feeding plays an essential role in dairy production. Therefore, the objective of this study was to evaluate two different dry cow feeding strategies regarding dry matter intake (DMI), metabolism and health aspects of dairy cows in the first 50 days after calving.

Eating Quality of Ribeye Steaks From Young Bulls and Steers Is Comparable: A Study Examining the Effect of Sex, Frame Size, and Feed Time on Palatability Attributes

Food Science &Nutrition, Volume 13, Issue 7, July 2025.
Palatability of ribeye steaks from young bulls and steers of 15 months age were comparable. Tenderness, juiciness, and beef flavor scores were similar with small‐framed animals being rated the highest scores. ABSTRACT The eating quality of older bull beef in the United States has been considered inferior due to its tough texture, undesirable flavor ...

Influence of Rumen Undegradable Protein Levels on Feed Intake and Milk Production of Dairy Cows

Journal of Dairy Science, 1991
Twenty-seven dairy cows in midlactation were utilized in two experiments using 15 and 12 cows to determine effects of varying the delivery of ruminally undegraded protein on feed intake, milk production, and some rumen and plasma characteristics. In Experiment 1, cows consumed alfalfa silage ad libitum and one of three barley-based concentrates with ...
