Abstract
Colostrum composition as well as colostrum IgG concentration varies among goat breeds. Among all the goat breeds, Murciano Granadina has the lowest level of immunoglobulin. The present experiment was conducted with the aim of investigating the number of times colostrum feeding (4 and 6 servings) in 24 hours on growth performance and safety parameters in Murcianogradina goat kids.The present study was conducted using a completely random statistical design and comparison of means using the T test. The duration of insemination was 24 hours. The number of 20 Murciano Granadina goat kids was studied in two treatments with 10 replications. The first group was fed 4 servings of colostrum and the second group was fed 6 servings of colostrum during 24 hours. The amount of colostrum consumed during the study period was 30% of the birth weight of the goat kids. The first dose of insemination was given to the goat kids immediately after birth and by hand. In general, the findings of this research showed that among all the parameters measured (colostrum compounds, growth performance and blood parameters as well as blood parameters related to immunity) among the two lactating groups studied (4 and 6), No significant differences were observed.The results of this study showed that the number of times and amounts of colostrum feeding in 24 hours after the birth of Murcianogranadina goats had no effect on the average daily weight gain as well as the blood serum immunoglobulin levels of the goat kids
