Factors Affecting Dry Matter Intake by Lactating Dairy Cows
Feed intake is the single most critical factor of dairy production, and performance of dairy cattle can be enhanced or hindered by environmental factors that affect it. These environmental factors can by divided into physical and climatic conditions. On modern dairies, the physical factors may be of more concern. Modern facilities provide the cow with protection from the natural elements. Howev...
متن کاملthe effects of high non fibrous carbohydrates diet on milk production, inflammation and molecular mechanism of innate immunity in lactating dairy cows
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...
Comparative feeding value of wood sugar concentrate and cane molasses for feedlot cattle.
Two feedlot cattle growth performance trials and a metabolism trial were conducted to evaluate the feeding value of cane molasses (CM) compared with wood sugar concentrate (WSC). The CM contained (as-fed basis) 73% DM, 8.6% ash, 48% total sugars, and 79.5 degrees Brix. The WSC contained (as-fed basis) 61% DM, 12.2% ash, 38.9% total sugars, and 29% lignosulfonate. When supplemented at 4% of diet...
متن کاملShort communication: Added value of rumination time for the prediction of dry matter intake in lactating dairy cows.
The objective of the current study was to quantify the change in the prediction of dry matter intake (DMI) resulting from the inclusion of rumination time (RT) in the 2001 National Research Council (NRC) DMI prediction model. Forty-one Holstein cows fed the same total mixed ration were involved in a 10-wk study. Individual DMI were measured daily. The accuracy and precision of the original NRC ...
متن کاملFat-Feeding Practices for Lactating Dairy Cows
Supplementing cows with fat can have several beneficial effects. It usually increases the energy density of the diet as starch or fiber is replaced with fatty acids. If milk production is increased, then feed efficiency may be improved. Less heat may be produced in the rumen during digestion of fat-supplemented diets as fatty acids are not digested in the rumen. Less heat produced during digest...
