Alimentación de terneros a base de calostro liofilizado en la Estación Experimental Tunshi

Abstract

The objective of the research was to evaluate the feeding of calves based on Iyophilized colostrum at Estación Experimenta Tunshi, in the Academic and Research Unit Dairy Bovines, which belongs to the Ciencias Pecuarias Faculty of the ESPOCH. The experimental units consisted of 6 calves under a simple statistical design that had 2 treatments, 4 repetitions and the size of the experimental unit was 3 calves per treatment, which were evaluated by two types of colostrum, T0 (control treatment) and T1 (Iyophilized colostrum), supplied for 3 days postpartum with an interval of 12 hours. The results obtained were submitted to the "t-student" test for means of two paired samples with a significance level of (P < 0.05). Obtaining the best results with T2 (lyophilized colostrum) in the following variables: Initial level of immunoglobulins IgG, initial level of immunoglobulins IgA and initial level of immunoglobulins IgM, while the variables initial weight, final weight, weight gain, final level of immunoglobulins IgG, Final IgA immunoglobulin level and final IgM immunoglobulin level did not report significant differences between the treatments analyzed. It was concluded that T2 (lyophilized colostrum) was the best treatment since the offspring acquired greater immunity at birth, decreasing the presence of mortality. The supply of Iyophilized colostrum is recommended as an alternative food within the farms.
