Prediction of Dry Matter Intake in Lactating Holstein Dairy Cows Offered High Levels of Concentrate
Accurate estimation of dry matter intake (DMI) is a prerequisite to meet animal performance targets without penalizing animal health and the environment. The objective of the current study was to evaluate some of the existing models in order to predict DMI when lactating dairy cows were offered a total mixed ration containing a high level of concentrates and locally produced agricultural by-pro...
متن کاملLiquid Feeds and Sugars in Diets for Dairy Cattle
Sugars are rapidly and extensively fermented in the rumen. Clearly, adding sugar to a diet already high in ruminally degraded carbohydrates should offer little benefit and could decrease digestibility of fiber, whereas diets that have less-than-optimal rumen degraded carbohydrate probably will benefit the most from addition of sugars. Therefore, dietary situations influence the optimum feeding ...
متن کاملThe feeding value of corn distillers solubles for lactating dairy cows.
Fifteen Holstein cows (10 multiparous and 5 primiparous) in early to mid lactation (79.3 +/- 9.2 d in milk) were used in a multiple 5 x 5 Latin square design with 4-wk periods to evaluate and compare the use of condensed corn distillers solubles (CCDS) and dried distillers grains with solubles (DDGS) in the total mixed ration. The forage portion of the diets was kept constant at 27.5% corn sila...
متن کاملLameness in dairy Cows
This paper intended to review the lameness in dairy cattle. But it was necessary to have an overview about the hoof anatomical structure, it's growth and overgrowth properties. Most common causes of lameness such as laminitis and its different clinical form or presentation such as sole ulcers, toe ulcers, white line disorders, sole and white linehemorrhages have been reviewed and discussed. ...
متن کاملProspective Effects of Regrouping, Number of Animals in Each Group and Concentrate Specificity on Profitability of Lactating Dairy Cows
Profitability of different grouping criteria was simulated in a dairy farm with 153 lactating cows that were divided into three groups of high (79), medium (40) and low (34) cows based on the milk records. Animals were reassigned to the new groups based on the following criteria using a decision support tool and the same three groups scenario: fat corrected milk 4%, days in milk (DIM), dairy me...
