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...
Interrelationships among ambient temperature, day length, and milk yield in dairy cows under a Mediterranean climate.
We examined the effect of calving month (CM) on the production of milk and milk protein by Israeli Holstein dairy cows located in the main climatic zone of Israel during their third and fourth lactations, and found it to be significant. Cows that calved in December produced the highest milk and milk protein yields, and those that calved in June produced the lowest, 92.8% of the maximum. The com...

Physiol. 216(5) : 1164-1169. 1969.-The study demonstrates the influence of ambient temperature on the excretion of epinephrine, norepinephrine, and their major metabolites. As a result of this work it is concluded that norepinephrine secretion increases in a co...
متن کاملAssociations among milk production and rectal temperature on pregnancy maintenance in lactating recipient dairy cows.
The objective of this study was to evaluate the associations among milk production, rectal temperature, and pregnancy maintenance in lactating recipient dairy cows. Data were collected during an 11-mo period from 463 Holstein cows (203 primiparous and 260 multiparous) assigned to a fixed-time embryo transfer (ET) protocol. Only cows detected with a visible corpus luteum immediately prior to ET ...
متن کاملInfluence of elevated ambient temperature on reproductive performance of boars.
Twelve Yorkshire boars were randomly assigned to one of two temperature controlled chambers to determine the influence of elevated ambient temperature on reproductive performance. Heat stressed boars were exposed to 34.5 -+ 1.0 C for 8 hr and 31.0 + 1.0 C for 16 hr daily for 90 days. Control boars were maintained at 23.0 -+ 1.0 C throughout the experimental period. Semen was collected twice wee...
