Raw vs Roasted Soybeans – Feeding roasted high oleic soybeans to high producing cows Soybeans are a common oilseed used in dairy rations as a source of both protein and energy. Recently high oleic soybeans (HOSB) have been developed due to interest from the human food industry to have an increase in oleic acid compared […]

Supplementing Rumen-Protected Methionine during the transition period under artificially induced heat stress improves metabolic and performance outcomes for cow and calf Heat stress during the transition period in dairy cows can impair both maternal performance and offspring development. Reduced DMI, lower milk yield and composition, and compromised fetal growth are commonly observed. Methionine, a key […]

Supplementing rumen-protected methionine to lactating dairy cows challenged with subclinical mastitis improves lactation performance and alleviates inflammation Mastitis, a prevalent production disease in dairy cattle, results in significant losses due to decreased milk production, increased veterinary costs, and heightened antibiotic use. Subclinical mastitis is particularly problematic because it lacks visible symptoms yet leads to elevated […]

Fat or Fatty acids? How do we use them to understand nutrient value? In general, the chemical nature and content of lipids in different feed ingredients used in ruminant diets is heterogeneous. As research in animal nutrition progresses, there is a greater understanding of nutrient utilization and value by farm animals. In order to develop […]

Assessing the value of protein feedstuffs for lactating dairy cows The autumn season is approaching and so is new crop corn and soybeans. Prices of feeds are often at their yearly low and dairymen are looking to contract material. Determining the value of different feeds is especially important this time of year. Historically, we have […]

Supply of branch-chain volatile fatty acids improve fiber digestibility and microbial growth but has a modest influence on production responses Branched-chain volatile fatty acids (BCVFA), which are formed by the degradation ofbranched-chain amino acids, are required growth-promoting factors for some fiberdegrading bacteria. Previous research has indicated that several rumen bacteria requireBCVFA for growth. Additionally, BCVFA […]

New Study from Ohio State University indicates a ½ lb butterfat yield difference and no change inbody weight gain due to the fat supplement used Fat supplements are commonly added to dairy cow diets to increase dietary energy densityand support milk production. At the same time, recovery of body condition is importantfor improving reproductive performance. […]
