192 Awardee Talk: Assessing performance metrics and nutritional intake to determine efficiency in Angus heifers at different production stages

Journal of Animal Science
Nutritional requirements and intake of beef cows vary across different growth and production stages, and the selection of replacement females with increased nutritional efficiency may improve the cow herd productivity.

353 Award Talk: From omics networks to targets of opportunity in ruminant nutritional physiology.

Journal of Animal Science
The first high-capacity molecular tool, “microarrays”, to monitor the expression of many genes in parallel was developed in 1995, using available information on complementary DNA (cDNA) sequences and expressed sequence tags (EST) from the small ...

18 Impact of nutritional management strategies on the gastrointestinal development, barrier function and metabolism of the calf and cow.

Journal of Animal Science
Gut health is a critical determinant of overall performance, disease resistance, and productivity in calves and cows. The gastrointestinal epithelium is tasked with nutrient absorption while maintaining a barrier against harmful luminal contents ...

Effect of Kalahari melon essential oil (Citrullus lanatus), butyric acid, and their blend in grower pig diets on blood hematology, nutritional status, liver enzyme activity, and oxidative stress

Tropical Animal Health and Production
The need for alternative growth promoters in pig production has arisen from the ban on the use of antibiotics as growth promoters. Important markers of an animal’s physiological and health state are blood biochemistry and hematology.

106 Exposure to ergot alkaloids and heat stress alter pulmonary arterial pressure and nutritional intake in beef heifers

Journal of Animal Science
Ergot alkaloid consumption is detrimental to cattle as it negatively impacts several physiological and performance parameters. The objective of this study was to evaluate changes in nutritional intake and different physiological and performance ...

264 A holistic nutritional approach for modulation of microbiome to improve pig performance and support health

Journal of Animal Science
The gut microbiome is in an intimate symbiosis with its host and their interactions have profound effects on the physiology, health, and performance of pigs across all life stages.

154 Physiological imbalances and targets in dairy cattle using metabonomics.

Journal of Animal Science
The life cycle of the dairy cow encompasses a number of transitions during which physiological mechanisms across multiple tissues must adapt in order to sustain a new metabolic state.

Differential Taurine Profiles Reflect Concentrate-Driven Physiological Adaptations in Japanese Black Steers During the Middle Fattening Stage.

Animal science journal = Nihon chikusan Gakkaiho
Taurine, a sulfur-containing amino acid derived from methionine or cysteine, plays key roles in bile acid conjugation, antioxidant defense, and lipid and glucose metabolism.
