Meat quality and cut yield of pigs slaughtered over 100 kg live weight
Meat quality and cut yield of pigs slaughtered between 100 and 150kg live weight were evaluated. Pigs (417 Agroceres PIC barrows and gilts) were fed a daily allowance of 2.8kg per head from 80kg until 100.71±0.85, 118.58±0.99, 134.07±1.18 or 143.90±1.24kg live weight. Seventy-one pigs were used for the evaluation of primal and subprimal cuts. There was no interaction between sex and slaughter w...
متن کاملBetween and within breed variation for lean growth and intramuscular fat content and fatty acid composition in pigs
A first experiment in 229 barrows examined the effect of the genetic type on growth, carcass composition and intramuscular fat (IMF) content and composition. Four genetic types were used: Landrace x Large White (LSLW), Duroc, either inseminated with boars from the same (D1D1) or a different line (D1D2), and Duroc x Iberian (D1IB). All pigs were reared until 200 days under the same conditions. I...
متن کاملExploring alternative models for sex-linked quantitative trait loci in outbred populations: application to an iberian x landrace pig intercross.
We present a very flexible method that allows us to analyze X-linked quantitative trait loci (QTL) in crosses between outbred lines. The dosage compensation phenomenon is modeled explicitly in an identity-by-descent approach. A variety of models can be fitted, ranging from considering alternative fixed alleles within the founder breeds to a model where the only genetic variation is within breed...
متن کاملThe influence of age at the beginning of Montanera period on meat characteristics and fat quality of outdoor Iberian pigs.
A total of 120 Iberian pigs of the Lampiña line that grew under outdoor conditions were used to study the effect of the age at the beginning of Montanera period (AM) on meat characteristics and fatty acid (FA) profile of subcutaneous fat. AM period is a free-range fattening phase from November to February in which pigs ate mainly acorns and grass. There were two treatments with two AM (20 pigs ...
متن کاملInfluence of feed restriction and sex on growth performance and carcass and meat quality of Iberian pigs reared indoors.
Iberian x Duroc pigs (n = 168), with an average age of 152 d and 42 +/- 2 kg, were used to investigate the effect of feeding regimen [ad libitum access to feed (AL) vs. 82% of AL from 152 to 201 d of age and 72% from 202 to 263 d of age (FR)] and sex (intact females, castrated females, and castrated males) on growth performance and carcass and meat quality. For the last 54 d before slaughter at...
