Sensor Technologies for Nutritional Management of Ruminants
… sensing technologies that could enable shifts in management to maximize productivity in ruminant production systems. In the first study, we assessed the use of existing sensor technologies to monitor ruminal volatile fatty acid (VFA) concentrations using pH sensing. Four ruminally cannulated …

Nutritional Management Strategies to Increase Energy Intake of Lactating Cows
<p>Two nutritional strategies to increase energy intake during early lactation were evaluated utilizing 71 Holstein dairy cows (34 primiparous and 3 7 multiparous) in a total lactation trial. Cows were randomly assigned at parturition to 1 of 3 dietary treatment regimes: Control (CON = 50:50 …

Holstein heifer behaviors and lactating cow nutritional management for improved reproductive performance on dairy farms
… performance on farms declines. Poor reproductive management on farms can be costly due to decreased milk production in late lactation, higher feed costs from a longer calving interval, and more labor and supplies from multiple breedings. To investigate techniques to improve the reproductive …

Effects of bodyweight and plane of nutrition on mitogenic capacity of mammary extracts in cell culture, mammary growth and development, and protein expression profiles of mammary tissue in Holstein heifers
… the effects of stage of development and nutritional management on mitogenic activity of mammary extracts and mammary parenchymal composition. Stage of development and nutritional management of heifers had minimal effects on the mitogenic capacity of mammary extracts, and no significant …

Regulation of glucose metabolism in dairy cattle
… during this period is being addressed by nutritional management with the possibility of the addition of supplements. The use of Ca-propionate as a supplement did not affect glucose metabolism in transition cows. The data revealed that insulin sensitivity was low during the transition …

Monitoring and improving reproductive performance of crossbred dairy cattle in Tigray Region, Ethiopia
… performance of cattle and their breeding management are unsatisfactory. Currently, the sole diagnostic tool in the country is rectal palpation, which is inaccurate for early pregnancy in cattle. The study assessed reproductive performance and major reproductive problems using questionnaire …

Agronomic and nutritional considerations for increased soybean productivity
… a comprehensive understanding of the agronomic, nutritional, and genetic factors that influence soybean yield. Despite recent agricultural innovations, there is a common perception that soybean yields have reached a plateau. While most producers overlook the fertility needs of soybean, others …

Trends in Equine Nutrition and the Effects of a Hindgut Buffer Product in Overconditioned Horses
… population is overweight due to feeding and management practices. Obesity is related to development of diseases that are detrimental to performance and potentially fatal in horses, including insulin resistance, laminitis, and equine metabolic syndrome (EMS). Objectives of this research …

Approaches for Developing and Implementing Precision Feeding Programs to Maximize Feed Efficiency
Nutritional management of dairy cattle is of importance to the industry due to its influence on production performance and association with large expenses for producers. Current ration formulation may be improved by predicting feeding recommendations for individual animals, rather than groups of …

Effects of early weaning on finishing feed efficiency, marbling development and retail product quality of beef steers
Beef cattle producers continuously search for nutritional management options that provide flexibility to production scenarios. Due to its positive effects on maternal productivity, early weaning is one such alternative strategy that has received considerable interest. To better understand the …

Influence of Prepubertal Dietary Protein and Age at First Calving on the Performance, Reproduction and Lactation of Replacement Beef Heifers
… CP were tested in six experiments using several nutritional management systems. Heifers were managed to calve first at 18 or 24 months of age. The effects of prebreeding protein and age at first calving were tested in several prebreeding production settings including normal weaning and creep …

Determining the Nutritional Status of Mature Beef Cows
… quality and cow performance may enhance the nutritional management of beef cows. In two 12 mo trials, mature beef cows (n=136) grazing tall fescue pastures were used to compare estimates of forage quality and animal performance. Forage quality was estimated by proximate analysis of forage …
