Remixing Lightweight Pigs in the Grower-finisher
A recent study has shown that sorting and regrouping lightweight pigs with pigs of similar size does not improve their growth performance and carcass characteristics. M. C. Brumm and coworkers (2002) hypothesized that managing variation in the nursery and grower-finisher by sorting and regrouping lightweight pigs might improve their performance. Five experiment stations (in Illinois, Iowa, Mich...
متن کاملCompensatory growth and nitrogen balance in grower-finisher pigs.
Sixteen castrated male pigs (averaging 21.2 +/- 4.9 kg) were used in two trials to investigate the effect of dietary amino acid content during the grower phase on growth performance and N balance. In each trial, pigs were assigned randomly to corn-soybean meal grower diets formulated to contain 5.0 or 11.0 g lysine/kg (as-fed basis). Common Finisher 1 and 2 diets were offered when pigs reached ...
متن کاملAssociation of RYR1 and MYOG Genotype with Carcass and Meat Quality Traits in Grower-finisher Pigs
The study involved 110 hybrid grower-finisher pigs from Polish Large White × Polish Landrace sows sired by Pietrain breed boars and their crossbreds with the 990 line and Duroc. The aim of the study was to determine an association of the polymorphism of RYR1, myogenin (MYOG) genes and carcass meatiness level with carcass slaughter value and meat quality traits in hybrid pigs. Better meat qualit...
متن کاملAssessing Nitrogen and Phosphorus in Excreta from Grower-finisher Pigs Fed Prevalent Rations in Vietnam*
Livestock production in Vietnam is, as in most Asian countries, increasing rapidly and changing into specialized highly intensified operations. The volume of animal excreta generated exceeds the capacity of the operation land base and cannot be utilized efficiently. As a consequence, there is a loss of plant nutrients from livestock farms that causes environmental pollution. This study carried ...
متن کاملPrevalence of gastro-oesophageal ulcers in grower-finisher pigs in the northern province of South Africa.
Ulceration of the gastric pars oesophagea is a common problem in intensive pig production that is often detected at slaughter. A survey was carried out at the Pietersburg abattoir in the Northern Province during a 6-month period. In total, 4320 pig stomachs were examined. Gastro-oesophageal ulcers were observed in 5.1% of the stomachs, gastric erosion in 15.2%, and hyperkeratosis in 18.9%. Time...
