Lysine Cow Milk Production

Lysine is available to the animal through feedstuffs with blood meal as one of the more common sources of lysine in the diet The rising price of blood meal is giving dairy producers and nutritionists a reason to look at rumen protected lysine products Selecting an alternative lysine source isn't as easy as it sounds though

Rumen

Rumen-protected choline served to reduce liver lipid in dairy cows when prepartum body condition score was 3 75 or greater and high-protein diets (10% RDP and 6 2% RUP) were fed prepartum (Hartwell et al 2000) On this basis targeted supplementation with rumen-protected choline is recommended even for moderately overconditioned cows (3 8 body condition

Effect of feeding rumen

The objectives of this study were to evaluate the effects of daily top-dressing (individually feeding on the top of the total mixed ration) with rumen-protected methionine (RPM) from 30 3 until 126 3 Days in milk on productive and reproductive performance in lactating dairy cows A total of 309 lactating dairy Holstein cows (138 primiparous and 171 multiparous) were randomly

Rumen Protected Amino Acids for Modern Dairy Cow

Feeding today's modern high producing dairy cow requires a level and balance of nutrients that matches genetic potential Total protein supply and overall balance of amino acids are important to milk production and efficiency of protein use by cows Amino acids Methionine and Lysine are often in short supply and not in the correct balance for cost-efficient protein use by lactating dairy

Effects of dietary rumen‐protected lysine on milk yield

This study investigated the effects of dietary rumen‐protected lysine (RPLys) on milk yield and composition in lactating cows fed diets containing double‐low rapeseed meal Twenty‐four cows were divided into three groups and fed one of three dietary treatments: 10% soya bean meal (SBM) diet (control) 15% double‐low rapeseed meal (DLRSM) diet and 15% DLRSM + 32 g/d
