Immune Response and Productive Performance of Dairy Buffaloes and their Offspring Supplemented with Black Seed Oil
Twenty pregnant buffaloes, eight weeks before the expected calving date, were assigned into two homogeneous groups of 10 animals each, according to their season of lactation (2nd to 8th season of lactation); The first group (G1) were fed on a ration consisting of concentrate feed mixture (22% yellow corn, 35% cotton seed meal, 33% wheat bran, 4% rice bran, 3% molasses, 2% limestone and 1% sodiu...
متن کاملFrequency of feed delivery affects the behavior of lactating dairy cows.
The objectives of this study were to examine how frequency of feed delivery affects 1) the behavior of group-housed and group-fed dairy cows and 2) the extent of feed sorting. These objectives were tested in two experiments. In each experiment, 48 lactating Holstein cows, split into groups of 12, were subjected to each of 2 treatments (over 10-d periods) in a cross-over design. The treatments f...
متن کاملDietary forage concentration affects the feed sorting behavior of lactating dairy cows.
The objective of this study was to determine whether the amount of forage in a total mixed ration influences feed sorting by cows and whether the extent of this sorting changes as they adapt to a new diet. Six lactating Holstein cows, individually fed once per day, were provided each of 2 diets in a crossover design (dry matter basis): 1) a higher forage diet (HF; 62.3% forage), and 2) a lower ...
متن کاملAdding liquid feed to a total mixed ration reduces feed sorting behavior and improves productivity of lactating dairy cows.
This study was designed to determine the effect of adding a molasses-based liquid feed (LF) supplement to a total mixed ration (TMR) on the feed sorting behavior and production of dairy cows. Twelve lactating Holstein cows (88.2±19.5 DIM) were exposed, in a crossover design with 21-d periods, to each of 2 treatment diets: 1) control TMR and 2) control TMR with 4.1% dietary dry matter LF added. ...
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...
