Clinical case: High percentage of returns-to-oestrus and of sows negative to the pregnancy ultrasound testing

There is an unusual increase of the returns-to-oestrus at 31-39 days. The majority are due to sows previously negative to the pregnancy ultrasound testing, and the returns-to-oestrus happened before 42 days.

Abstract

A simple novel measure of passive transfer of maternal immunoglobulin is predictive of preweaning mortality in piglets

The Ig immunocrit method is a simple and useful in assessing the initiation of colostrum and the nursing ability of sows, and the effect of these events on preweaning piglet mortality.
