New insights on ill-thriftiness in early-weaned buffalo calves
AIM The present study was designed to: (1) Investigate the effect of weaning time on various metabolic indices and growth pattern in buffalo calves compared to cow calves under field condition and (2) Shed light on the potential relationship between early weaning, growth metabolites, and suboptimal growth (ill-thrift) in buffalo calves. MATERIALS AND METHODS A total number of 18 neonatal calv...
متن کاملHow Much Supplement is Needed for Early Weaned Calves Grazing Rye- Ryegrass Pastures?
The objective of this study was to evaluate the effect of three levels of supplement on forage intake and animal performance of early weaned calves grazing rye-ryegrass pastures from January to May. Treatments were three levels of concentrate (1, 1.5, and 2% of body weight [BW]), and animals were 90-d-old Angus-crossbred early weaned calves. Calf ADG increased from 1.6 to 1.9 lb/d as supplement...
متن کاملEarly attachment sites for Shiga-toxigenic Escherichia coli O157:H7 in experimentally inoculated weaned calves.
Weaned 3- to 4-month-old calves were fasted for 48 h, inoculated with 10(10) CFU of Shiga toxin-positive Escherichia coli (STEC) O157:H7 strain 86-24 (STEC O157) or STEC O91:H21 strain B2F1 (STEC O91), Shiga toxin-negative E. coli O157:H7 strain 87-23 (Stx(-) O157), or a nonpathogenic control E. coli strain, necropsied 4 days postinoculation, and examined bacteriologically and histologically. S...
متن کاملEffects of probiotic dietary supplementation on diarrhoea patterns, faecal microbiota and performance of early weaned calves
Twenty Lithuanian Black-and-White calves (10 bulls, 10 heifers) were used to evaluate the effects of the supplemental probiotic product, Enterococcus faecium M74 (2.4 g/day/calve), added to fresh milk and skimmed milk in a 56 day-study. The probiotic was administered by dietary supplementation to first group of calves and their respective pens (probiotic group), whereas the second group (contro...
متن کاملNutrition and Immunity for Pre-weaned Dairy Calves
Dairy calves are extremely susceptible to gastro-intestinal disease during the pre-weaned period. The risk for enteric disease decreases as the calf ages; therefore, it is important to break the pre-weaned period up into at least 2 distinct phases that likely need to be managed differently, early life (1st and maybe the 2nd week of life) and the remaining time the calf is fed fluid. When a calf...
