Effect of Sperm Photostimulation in improving reproductive parameters with the use of Artificial Insemination

The use of artificial insemination (AI) with fresh semen is one of the key tools that have established the basis of exponential growth in world pork production last years. The success of the AI is basically due to that it is an economical and easy technique to use in pig farms of any size. Furthermore, the reproductive performance achieved with AI is optimal.

Relationship between ovulation rate and litter characteristics at birth

The genetic selection for increased litter size has resulted in a disproportionate increase in ovulation rate (OR). A higher OR was linearly related with decreased placental length at day 35 of pregnancy, which could inhibit foetal growth during further pregnancy (Da Silva et al., 2016). As increased litter size has resulted in a decreased piglet birth weight and increased within litter birth weight variation, we investigated the relationship between OR and litter characteristics at term.

Characteristics of repeat-breeding female pigs on southern EU commercial farms

A repeat-breeding (RB) occurrence increases non-productive days of female pigs
(NPD), and consequently decreases herd productivity. However, characteristics of RB female pigs are not well defined or studied in swine. Also, few studies have compared lifetime reproductive performance between RB and non-RB female pigs.
