Effect of lactation feed intake and creep feeding on sow and piglet performance
Increasing total feed intake of sows during lactation may improve litter gain and sow productivity
Effects of dietary protein supply, weaning age and experimental enterotoxigenic Escherichia coli infection on newly weaned pigs: performance
Increasing weaning age and decreasing dietary protein level may help to minimise the effects of post-weaning colibacillocis on performance
One-site and multi-site swine rearing systems II
In a previous article (March '99) we suggested a standardized terminology for the description of swine production systems. The terminology covered stages of production (breeding, nursery, finishing), management practices (isowean, sourcing of pigs, movement of pigs), and physical aspects and geographical locations of production facilities (numbers of buildings, loci, and sites).
One site and multi-site swine rearing systems
A new proposed system for terms to use in describing the various one site and multi-site production systems that have evolved in the pork production industry, and a simplified system for diagraming various types of pig farms.
