Colostrum management for dairy calves.
Colostrum management is the single most important management factor in determining calf health and survival. Unfortunately, a significant proportion of North American dairy calves suffer from failure of passive transfer of antibodies from colostrum, contributing to excessively high preweaning mortality rates and other short- and long-term losses associated with animal health, welfare, and produ...
متن کاملEffect of fat content of colostrum on voluntary colostrum intake and fat utilization in newborn pigs.
The effects of colostral fat level on voluntary colostrum and ME intake were determined in 25 newborn pigs during the first postnatal day. Within a litter, five pigs were obtained before nursing and allotted on the basis of initial body weight (BW) at 2 h of age to one of the five treatments: killed or ad libitum bottle-fed sow colostrum containing 2.5, 5.0, 7.5, or 10.0% of total fat. A total ...
متن کاملEffect of colostrum intake on diarrhoea incidence in new-born calves.
In a survey which lasted one year and included data of 73 dairy cows with their calves, colostrum immunoglobulin G (IgG) of 22 primiparous cows and serum IgG of their calves were lower than the corresponding IgG levels of 51 multiparous cows and their calves. Serum IgG concentration was not correlated with diarrhoea incidence. Although there were no seasonal differences in the IgG concentration...
متن کاملThe effect of ruminal fluid preparations on the growth and health of newborn, milk-fed dairy calves.
The objective of this study was to determine the effect of oral doses of ruminal fluid (RF) on the growth and health of newborn, milk-fed heifer dairy calves (0 to 6 wk of age). Calves given 8 ml of RF each day until weaning gained more weight and had fewer scours than controls that did not receive RF. Because RF that was exposed to oxygen or was autoclaved also gave a response, it is unlikely ...
متن کاملQuercetin Feeding in Newborn Dairy Calves Cannot Compensate Colostrum Deprivation: Study on Metabolic, Antioxidative and Inflammatory Traits
Immaturity of the neonatal immune system is causative for high morbidity in calves and colostrum intake is crucial for acquiring passive immunity. Pathogenesis is promoted by reactive oxygen species accumulating at birth if counter-regulation is inadequate. The flavonol quercetin exerts antioxidative and anti-inflammatory effects that may enhance neonatal health. The aim of this work was to stu...
