Serum evaluation of cholesterol and triglycerides of serum-producing horses fed concentrate with 15% or 22% of crude protein

Abstract

The hyperimmune serum production in horses is still fundamental to obtain the serum used in the treatment of some diseases like tetanus and diphtery. In order to determine the benefit of the utilization of high-protein concentrate in serum-producing horses dietary of Butantan Institute, the serum concentrations of cholesterol and triglycerides were screened from a group of 32 anti-diphteric serum-producing horses. Those horses were distributed occasionally in two groups of 16 equines. The animals of group A were fed with a concentrate with 15% of crude protein (CP) and the animals of group B were fed with a concentrate with 22% of CP. The serum samples were obtained in two immunization periods, in moments previous to the antigen inoculation, before the bleeding of production and with a delay of 15, 30 and 45 days after the last bleeding. The serum concentrations of triglycerides were higher in group B in day 58 of the first period (p<0,001) and in the second period were higher in group A in days 95 and 137 (p<0,04) and in group B in day 109
