Avaliação da imunidade passiva em cabritos da Raça Moxotó.

Abstract

Placental barriers in ruminants do not allow the passage of immunoglobulins from dams to neonates, therefore consumption of colostrum is required to provide passive immunity until kids immunity is established. The objective of this experiment was the determine a management that allowew the best acquisition of colostrums antibodies. This trial was conducted at the Centro de Saude e Tecnologia Rural - UFCG - Patos - Paraiba. Moxoto goats parturitions were supervised to enable pre-suckling blood samples of 17 kids before colostrums intake. Utilizing a completely randomize design the kids were submitted to two treatments: Tl (n=12) kids were bottle-fed with 140 ml of colostrums in the first hour of life and. T2 (n=5) kids were allowed to nurse the dam for 48 hours and ingested colostrums "ad libitum". Forty-eight hours after birth a blood sample was collected again from each kid. Levels of serum total protein estimated the acquisition of immunity. We Kids had adejite protein serum leuls, buy Kids from T2 demonstrated higher levels of total serum protein.. So, the management of T2 was considered the best one in providing adequate passive transfer of immunity.
