the 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...

Biochemical Characterization and Antibiogram of Staphylococcal Microorganisms Associated with Subclinical Mastitis in Lactating Crossbred Cows

Bovine subclinical mastitis (BSM) is a serious economic concern to the dairy industry, and is difficult to control due to elusive clinical manifestations of the ailment. The disease with primarily of microbial aetiology is amenable to antibiotic therapy, but the outcome is uncertain due to involvement of a plethora of microorganisms, host-specificity of the pathogens, and incessant evolution of...

Stockpiled forage or limit-fed corn as alternatives to hay for gestating and lactating beef cows.

In Exp. 1, 31, 24, and 17 mature, pregnant Simmental x Angus cows (initial BW = 662.0 +/- 10.4 kg) in each of 3 yr were used to determine the efficacy of stockpiled orchardgrass, limit-fed corn, or ad libitum hay for maintaining cows in mid- to late gestation, respectively. In Exp. 2, 24 mature, pregnant crossbred cows (initial BW = 677.7 +/- 9.4 kg) per treatment in each of 3 yr were used to d...
