The thermal needs of early weaned pigs were examined by placing pigs that were weaned from 13 to 16 days in indirect calorimeters and exposing them to four different temperature regimes. Pigs, in groups of ten (3 ft. 2 /pig), were weaned into four chambers at 88, 84, 80, and 76 o F and the temperature decreased by 2 o F per week for three weeks post-weaning. The feed efficiency and average dail...

Four feedlot experiments with 774 cattle have been completed during 1969 to 1970 evaluating two forms of tylosin activity (50, 75 and 100 mg per head per day continuously of tylosin phosphate or tylosin urea adduct) in high concentrate rations. Continuous administration of these three levels of antibiotic activity from either form of tylosin (1) reduced the incidence of liver abscesses, (2) inc...

in order to compare the effects of different weaning strategies on feed intake, structural growth measurement and health, blood metabolites and economic efficiency of young dairy calves, twenty four female holstein calves were used. calves after birth were randomly assigned into one of three weaning strategy as follow: 1) weaning based on feed intake, 2) weaning based on weight gain (30 kg weig...

Thirty two Holstein female calves (initial body weight = 40±3.0 kg) were used to investigate the effects of probiotic and prebiotic on average daily gain (ADG), fecal E. coli count, white blood cell count, plasma IgG1 level and cell-mediated immune response to injection of phytohemagglutinin in suckling female calves. Calves were assigned randomly to one of the four treatments, including whole ...

Pigs were weaned at 16 to 20 days of age and fed diets containing either dried whey or 6% dried porcine solubles (DPS), partially replacing dried whey protein, and one of two combinations of feed additives (either ZnO + CSP 250 or CuSO4 + Mecadox) in a 2 × 2 factorial arrangement. The diets were fed for 2 weeks and followed by a common diet for 3 weeks. Feeding the DPS-containing diet during we...

Labeo rohita, Gibelion catla, Cirrhinus mrigala, Ctenopharyngodon idella and Hypophthalmichthys molitrix were grown together for 365 days in triplicate ponds. Six iso-caloric feeds having varying protein levels i.e. 22, 24, 26, 28, 30 and 32% were prepared and supplemented to fish at 2% fish weight daily. Significantly, higher final average weight (793 ± 197 g) and total length gain (398 ± 40 m...
