Manipulating Forage-to-concentrate Ratios to Enhance Performance and Carcass Traits of Holstein Steers
Modern dairy beef feeding requires close attention to a host of nutrition and management factors that affect gain, efficiency of gain, carcass traits, and profitability. One tool the nutritionist and feedlot operator has is manipulation of forage:concentrate (F:C) ratios. Initial research and development in F:C ratios was primarily to determine the performance response by dairy beef steers to i...
متن کاملEffect of Dietary Forage to Concentrate Ratios on Dynamic Profile Changes and Interactions of Ruminal Microbiota and Metabolites in Holstein Heifers
A better understanding of global ruminal microbiota and metabolites under extensive feeding conditions is a prerequisite for optimizing rumen function and improving ruminant feed efficiency. Furthermore, the gap between the information on the ruminal microbiota and metabolites needs to be bridged. The aim of this study was to investigate the effects of a wide range of forage to concentrate rati...
متن کاملUse of an in vitro Rumen Gas Production Technique to Evaluate the Nutritive Value of Five Forage to Concentrate Ratios
This study presents the chemical composition and in vitro fermentation of five diets with different forage (alfalfa) to concentrate (faba bean) (F:C) ratios, F0:C100, F25:C75, F50:C50, F75:C25, F100:C0 on a dry matter (DM) basis. Results indicate that the chemical composition in term of organic matter (OM), ether extract (EE), crude protein (CP), acid detergent fiber (ADF), neutral detergent fi...
متن کاملManure and Nutrient Partitioning, Accretion, and Excretion in Holstein Heifers
Considerable changes have occurred in environmental regulations in recent years, only one of which is the requirement of stand alone heifer operations and feedlots to carry environmental permits. While growth of heifers is a widely researched topic, publications concerning nutrient utilization, partitioning, and excretion are scarce and are becoming necessary. That combined with the fact that f...
