What insemination method should I use?
We continue our series of articles in which swine reproduction and artificial insemination expert Javier Gil shares key points about proper management to improve fertility and prolificacy. This article addresses the criteria to establish correct insemination methods.
Weaning straight into pens

Clinical case: Increase of returns in summer and low annual prolificacy
The farm reports a problem of low prolificacy (mean annual live births of 11.91) and low fertility in summer, with a marked increase in acyclic returns.

Measures of the ovaries and uterus during development of gilts selected for differences in uterine capacity
Selection for increased UC results in larger ovaries and uterine horns, but TRU was not useful for estimating these traits in gilts of the age studied.
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.
Management of the breeding chart (II)
In the first part of management of the breeding chart we basically looked at how it can help us to control returns. In this second part we will look at other applications.
