چکیده
the study was carried out on 120 crossbred holstein × shahiwal dairy cows for a period of 150 days to quantify the influence of dietary energy and protein intake on yield and composition of milk. total 12 dairy farms having similar housing systems and holding at least 20 dairy cows in between mid to late lactation were selected for study purposes. the farms were located in the peri-urban and urban areas of chittagong, bangladesh. milk samples were collected from individual cow. milk from cows having same body condition scoring (bcs) were mixed together to make a composite sample. chemical analyses of the samples were carried out in triplicate for fat, protein, lactose, total solids (ts), solids not fat (snf) and ash. dietary metabolizable energy (me) and crude protein (cp) intake were measured by analyzing the amount of total mixed ration ingested by the individual cow. results indicated that, me intake (mj/d) significantly (p

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...
