Abstract Transportation of unweaned calves involves periods feed restriction and stress without a fully developed immune system gastrointestinal tract. The use additives to enhance intake immunity at arrival could be strategy minimize those negative effects. Holstein male (n + 39; 16 ± 1.2 d age 46 0.1 kg BW) were used evaluate the effect mixture (FA) comprising palatability enhancers, standard...

This investigation's purpose was the evaluation effects of physical forms corn and forage sources on growth performance, blood parameters, ruminal fermentation Holstein calves. Forty-eight calves (38.2 ± 1.2 kg BW) were used in a completely randomized design with 4 treatments 12 replications for 65 days. The were: 1) Basal diet + mashed form wheat straw (MCWS), 2) flacked (FCWS), 3) corn+ Sugar...

Previous studies have determined that stress causes decreases in feed intake and efficiency in livestock, but the effect of repeated transport on these parameters has not been well studied. This study determined how repeated transport affected calf post-transport behavior, feed intake, ADG, and feed conversion. Thirty-six 4-mo-old Holstein steer calves were housed in groups of 6 with each group...

this study was done for identification of bacterial agents in calf pneumonia and determination of their antimicrobial susceptibility. bronchoalveolar lavage was done on fourteen pneumonic and seven normal holstein calves between 1-3 month old. in bacteriological examination on the fluid of bronchoalveolar lavage, mycoplasma spp. were isolated from 4 (28.6%) pneumonic calves and 1 (14.3%) health...

This study was conducted to compare the meat qualities of loin (m. longissimus dorsi) and top round (m. semimembranosus) from Hanwoo and Holstein veal. Ten Hanwoo and Holstein calves were randomly selected from a local cattle farm and raised. They were slaughtered when they were 8 mon old and weighed. Weight and percentage in primal cuts and slaughter performance of Hanwoo and Holstein veal cal...

Sodium bicarbonate and yeast culture effects on ruminal fermentation, intake, and growth were evaluated in young calves. In trail 1, nine ruminally cannulated Holstein calves averaging 12 wk of age were fed control starter (17% CP) or starters containing 3% sodium bicarbonate or .2% yeast (Saccharomyces cerevisiae) culture in a 3 x 3 Latin square. Calves were fed for ad libitum consumption for ...

Background: During perinatal period, the immune system of calves is developing, making them vulnerable to infectious diseases that affect their growth or increasing mortality. Phytobiotics have various physiological effects on animals could improve performance and health. In this study, effect a feed herbal mixture made from Azadirachta indica Phyllanthus niruri were evaluated in dairy calves. ...

A unique law (Act 201) requiring livestock markets to place an identifying mark on calves up to 90 kg each time they are sold went into effect in Wisconsin in 1993. The intent of the law is to reduce the number of times calves are resold and hence become "stale." The original proponents of the law proposed that calves be ear-notched each time they are sold. Ear notching, however, was resisted b...
