Effect of high-concentrate diet on amino acid transporter expression and milk quality in Holstein dairy cows.
In order to evaluate the effect of high-concentrate diet supplementation on milk protein content, six Holstein dairy cows were assigned into high-concentrate diet (HC) or low-concentrate diet (LC) groups (N = 3/group) for 50 days. With regard to milk protein, HC feeding significantly reduced the percentage of milk protein (P < 0.01), and milk protein yield also reduced. The milk somatic cell co...
متن کاملShort communication: Ca2+-adenosine triphosphatase protein expression in the mammary gland of periparturient cows.
The objectives of this study were to measure the changes in protein expression of the mammary Ca2+-ATPases during the periparturient period and to determine whether Ca2+-ATPase protein expression in the mammary gland is related to milk fever (MF) development. Abundance of Ca2+-ATPase in mammary tissue and milk fat globule membranes was determined by Western blotting. The secretory pathway Ca2+-...
متن کاملFertility of Holstein Cows in Chengdu, China**
Data on the use of breeding records of dairy cattle farm of Fenghuang-shan in Chengdu areas during a period of six years is systematically analyzed. The results show that Holstein heifers have their 1st estrus at an average age of 513.6±46.7 d which is not related to the calving season. Estrus mostly occurs in the months with mild ambient temperature (March, April, May, November and December). ...
متن کاملBlood metabolic profiles in Uruguayan Holstein and Uruguayan Holstein x New Zealand Holstein-Friesian dairy cows
Blood metabolic profiles were determined from 40 days prepartum to 60 days postpartum in Uruguayan Holstein (UH) (n = 13) and UH x New Zealand Holstein-Friesian first cross (UH-NZHF) (n = 13) cows with seven in each group experiencing their second lactation (L2) and six experiencing their third lactation (L3). Non-esterified fatty acids increased around calving and tended to be greater in UH-L3...
متن کاملEffects of short dry periods on performance and metabolic status in Holstein dairy cows.
To evaluate effects of different dry period lengths on milk yield, milk composition, and energy balance of dairy cows, 122 multiparous and primiparous Holstein dairy cows were used in a completely randomized experimental design with 56-, 42-, and 35-d dry period lengths. Actual dry period lengths for respective treatments (TRT) were 56 +/- 5.1 d, 42 +/- 2.1 d, and 35 +/- 2.7 d. Overall, cows in...
