Watch for the monitoring of farrowings
This watch has three circles: the blue one represents the hours, the green one the liveborn piglets, and the red one the stillborn piglets.
Consequences of different dietary energy sources during follicular development on subsequent fertility of cyclic gilts
These results suggest that it is possible to manipulate dietary insulin response in cyclic gilts and, thus, improve reproductive efficiency when feeding starch as the main energy source during the late luteal and follicular phases of the cycle.
At what age and weight should we inseminate our gilts?
20 years ago we inseminated gilts when too small, then we inseminated them when too heavy, and now we are returning to an intermediate weight.
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.
Compounds from multilayer plastic bags cause reproductive failures in artificial insemination
This is the first described relationship between reproductive failure and toxic compounds released from plastic bags.
Supplementing cryopreservation media with reduced glutathione increases fertility of sows
Supplementing freezing media with 2 mm GSH greatly improves boar sperm cryopreservation technology, as it significantly improves the fertilizing ability of frozen-thawed spermatozoa.
Coloured pegs for the identification of the number of returns to oestrus of the sows
The goal is to identify the number of returns to oestrus of the sows quickly and at a glance using coloured pegs.
Piglet birth weight and litter uniformity: Effects of weaning-to-pregnancy interval and body condition changes in sows of different parities and crossbred lines
Litter uniformity is compromised by severe sow body condition loss during lactation and improved in sows with a prolonged WPI. These effects are likely related with (insufficient) restoration of follicle development.
United Kingdom: wean more pigs to be more profitable
The aim is to help every producer move towards an extra three pigs per sow per year weaned.
