Effects of Feeding Rumen Protected Choline and Vitamin E on Milk Yield, Milk Composition, Dry Matter Intake, BodyCondition Score and Body Weight in Early Lactating Dairy Cows
Twenty four primiparous and multiparous Holstein cows on early lactation, beginning five weeks postpartum, were used for four weeks to investigate the effects of supplemention of rumen-protected choline (RPC) or vitamin E on milk yield, milk composition, dry matter intake, body condition score and body weight. The cows were randomly assigned to one of the following treatments: I)no supplement (...

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Dry period plane of energy: Effects on feed intake, energy balance, milk production, and composition in transition dairy cows.
The objective was to investigate the effect of different dry cow feeding strategies on the degree of ketonemia postpartum. Epidemiologic studies provide evidence of an association between elevated β-hydroxybutyrate (BHBA) concentrations in postpartum dairy cows and a decreased risk for reproductive success as well as increased risk for several diseases in early lactation, such as displacement o...
متن کاملEffect of different levels of monensin in diets containing whole cottonseed on milk production and composition of lactating dairy cows
The objective of this study was to determine the effects of feeding different levels of monensin on feed intake, milk production and composition, and milk fattyacid profile in lactating Holstein cows. Four multiparous cows averaging 517 ± 47 (SD) kg in body weight and 101 ± 19.8 (SD) days in milk were housed individually in tie-stalls. The study was conducted as a 4 × 4 Latin square design for ...
متن کاملDry Matter Intake, Milk Yield and Milk Fatty Acid Composition of Dairy Cows Fed Raw or Microwave Irradiated Safflower Seed as a Substitution to Cottonseed
The present study was conducted to evaluate the effects of using raw or microwave irradiated safflower seed on dry matter intake, milk production and composition, milk fatty acid profile, blood parameters, and nutrient apparent digestibility in early lactation cows. Nine multiparous Holstein cows at early lactation were randomly assigned to one of three treatments based on 3 × 3 balanced latin ...
