Interaction effect of starter physical form and alfalfa hay on growth performance, ruminal fermentation, and blood metabolites in Holstein calves
The present study was conducted to evaluate the effects of physical form of starter and alfalfa hay (AH) provision on growth performance, ruminal fermentation, and blood metabolites of Holstein dairy calves. Forty-four 3d-old Holstein dairy calves with a mean starting BW of 39.9 ± 1.1 kg were used in a 2 × 2 factorial arrangement. The factors were dietary forage level (0 or 150 g kg-1</sup...
متن کاملIntake of High Producing Holstein Cows Grazing Pasture or Fed a Total Mixed Ration
(week 4). Intake was estimated in week 4 by dosing twice daily with 5 g Cr 2 O 3 for 10 days. Fecal samples were collected twice daily on days 7 to 11 of Cr 2 O 3 dosing, with pre-grazing pasture being sampled on days 6-10 of dosing. Fecal output, calculated from fecal chromium concentrations, and in vitro digestibility (IVDMD) were used to calculate intake (Parker et al. 1989). The intake of c...
متن کاملRumen fermentation and performance of Hanwoo steers fed total mixed ration with Korean rice wine residue
BACKGROUND This study was conducted to evaluate the effects of adding Korean rice wine residue (RWR) in total mixed ration (TMR) on in vitro ruminal fermentation and growth performance of growing Hanwoo steers. METHODS For in vitro fermentation, the experimental treatments were Control (Con: 0 % RWR + TMR), Treatment 1 (T1: 10 % RWR + TMR), and Treatment 2 (T2: 15 % RWR + TMR). The rumen flui...
متن کاملPerformance of lactating dairy cows fed varying levels of total mixed ration and pasture.
Two, 8-week experiments, each using 30 lactating Holstein cows, were conducted to examine performance of animals offered combinations of total mixed ration (TMR) and high-quality pasture. Experiment 1 was initiated in mid October 2004 and Experiment 2 was initiated in late March 2005. Cows were assigned to either a 100% TMR diet (100:00, no access to pasture) or one of the following three formu...
متن کاملPerformance of lactating dairy cows fed macerated forage conserved as silage and hay
Suwarno, Wittenberg, K. M., Ingalls, J. R. and McCaughey, W. P. 2000. Performance of lactating dairy cows fed macerated forage conserved as silage and hay. Can. J. Anim. Sci. 80: 123–129. The effect of forage maceration at harvest on silage characteristics and its effect on lactation performance of Holstein cows were determined. Either a roller conditioner or a prototype forage macerator manufa...
