Eficácia vacinal via imunização passiva matriz - leitão para controle de Escherichia coli

Abstract

The enteric colibacillosis neonatal is among the main factors affecting the productive and reproductive performance of pigs reared in intensive conditions of management. Therefore it is essential to the use of vaccines that help to raise the immunity of the arrays and piglet Escherichia coli. The objective of this study was to test the action of two distinct types of vaccines available in the market by generating tables and comparisons between scores of diarrhea and mortality from different groups in the period of maternity leave in a property in the locality of Line Almeida, city of Boa Vista do Buricá, Northwest region, State of Rio Grande do Sul, Brazil. One hundred (100) gene arrays – DB-Danbred and 90 thousand one hundred and eighty-three (1,183) piglets DB-90 were used in two treatments being 50 arrays and 580 piglets in Group A and 50 arrays and 603 piglets in Group b. Group A of matrices has been immunized with the vaccine (COLISUIN-CL ®) to sixty (60) and eighty (80) days of gestation and the Group B (Suvaxyn EC4 ®) with single dose to ninety (90) days of gestation intramuscularly deep behind the ear. After delivery were collected daily data of number of piglets born alive, weight leitegada, score of diarrhoea and deaths and weaning were observed the weights of the piglets. The absolute data were compared in tables and graphs. In Group A was observed lower efficiency for weight gain (7, 042Kg), percentage of deaths by colibacillosis (64.29%) and diarrhea score (2.6) already in Group (B) weight gain, percentage of deaths by colibacillosis and scoring were diarrhea, 872Kg 7, 34.92% and 2.1 respectively.
