Two experiments were conducted to evaluate the use of pulse grains in receiving diets for cattle. In Exp. 1, 8 Holstein (615 +/- 97 kg of initial BW) and 8 Angus-crossbred steers (403 +/- 73 kg of initial BW) fitted with ruminal and duodenal cannulas were blocked by breed and used in a randomized complete block design to assess the effects of pulse grain inclusion in receiving diets on intake, ...

The effect of calf weaning age on cow and calf performance and feed utilization was investigated over 2 yr. Multiparous, crossbred, lactating beef cows (n = 156) with summer-born calves were blocked by prebreeding BW, stratified by calf age, and assigned randomly to 1 of 4 treatments within strata. The experiment was a randomized complete block design with a 2 × 2 factorial arrangement of treat...

The aim of this study was to estimate direct and maternal genetic parameters for age at sale (AS, d), BW (kg), price (PR, €/kg), and market value (MV, €/calf) of Brown Swiss male calves (Bos taurus) from first- (n = 6,719) and second- (n = 4,405) parity dams marketed at livestock auctions from 2003 to 2007, and destined for veal production. Market value was calculated as the product of PR and B...

a comparative study on the effect of erythromycin and ivermectin on abomasal emptying in holstein-friesian calves motilides namely erythromycin have a great ability to increase abomasal emptying rate. the aim of this study was to evaluate the abomasal emptying rate in calves receiving either erythromycin or ivermectin. five male holstein-friesian calves were given each of the following 4 treatm...

Three 2.4-ha wheat (Triticum aestivum L.) fields were used to test the effects of maturity at harvest (boot vs. dough) and preservation method (hay vs. silage) on forage yield, chemical composition, and animal performance when fed in mixed diets. Forages were incorporated into 4 diets in a 2 x 2 factorial arrangement of treatments with hominy feed, soybean hulls, and cottonseed meal as the prim...

Ten Bos indicus x MARC III (initial BW = 303 +/- 25 kg) and 10 MARC III (initial BW = 322 +/- 16 kg) steers were used in a 2 x 2 factorial design to determine whether cattle age or Bos indicus crossbreeding influence site of digestion of a high-grain diet. Initially, five Bos indicus x MARC III and five MARC III steers were fitted with duodenal cannulas and adapted to a 95% concentrate diet tha...

During fall, 30 Holstein calves were randomly assigned to three housing treatments from birth to weaning: conventional wooden hutches, enclosed molded polyethylene domes, and thermomolded opaque polymer hutches with ridge-top ventilation systems. The wooden and polymer hutches had outdoor pens. Fifteen calves, 5 in each housing type, were fitted with portable data loggers to record ambient (cal...

Holstein calves were fed pelleted starter diets with crude protein (CP) concentrations of 18%, 22% and 24% per dry matter (DM) containing soybean meal (SBM) (SBM18, SBM20 and SBM24), respectively, for 10 weeks from 14 days of age. Another diet with a CP concentration of 18% per DM was tested using commercial xylose-soybean meal (XSB; Yasminomax) instead of SBM. Each diet was fed to 24 calves an...

Abstract Male Holstein calves (n = 80; 42.7 ± 1.44 kg and 14.2 0.81 days of age) were used to evaluate the effects colostrum consumption feed restriction on performance, energy balance (serum concentration BHB NEFA), behavior marketed transported during 19h. Well-colostrated (WC) received 4L within first 2h after birth 2L in next 3 feedings poor-colostrated (PC) birth. At approximately 14 d age...

the objective of this study was to determine the effects of supplemented selenium (se) on plasma cortisol, red blood cell glutathione peroxidase activity (rbc gsh-px-1), concentration of immunoglobulin g (igg) and body weight in pneumonic suckling calves. ten holstein suckling male calves were randomly allocated to two groups and fed either unsupplemented milk (control) or with milk supplemente...
