New data on oestrus synchronization in the sow

Comparison of Different Methods of Oestrus Synchronization on Reproductive Performance of Farahani Sheep in Iran

This experiment was carried out on 123 Farahani ewes from a herd in Delijan city in Markazi province of Iran to determine the best short-term method for oestrus synchronization. Ewes were divided into five experimental groups randomly: group 1) use of controlled intervaginal drug release devices (CIDR) for 7 days with intramuscular (IM) injection of PGF2α on zero day and IM injection of 500 IU ...

Automatic detection of oestrus and health disorders using data from electronic sow feeders

This article suggests a method for detecting oestrus, lameness and other health disorders for group housed sows fed by electronic sow feeders (ESF). The detection method is based on the measure of the individual eating rank, modeled using a univariate Dynamic Linear Model. Differences between the predicted values of the model and the observations are monitored using a control chart: a V-mask is...
