Resumo: | Four treatments were performed: treatment 1: from birth until the first 48 hours after birth, the calf sucked ad libitum on her mother, the four teats, being a little in each teat ; treatment 2: from birth until the first 48 hours after birth, the calf suckled ad libitum on the right front teat; treatment 3: from birth until the first 48 hours of life, all teats were milked and the calf was provided colostrum by bottle; treatment 4: from birth until the first 48 hours of life, all teats were milked and milk replacer was fed to calves by bottle. We measured the concentration of Immunoglobulin G (IgG) in the blood of 21 calves harvested at 48 hours of life. The density of colostrum fed to the animals was measured with a hydrometer . In animals subjected to treatment 3, was detected higher transfer of IgG than those of treatments 1 and 2 which in turn showed acquisition of immunity to the animals of treatment 4. There was no significant difference between the responses measured in treatments 1 and 2. We have detected a high correlation between the results obtained in the test of refraction and the obtained in radial immunodiffusion test (r = 0,90) and there was coagulation solution of glutaraldehyde in all sera IgG concentration higher than 983,68 mg/dL. |
