Multiple regression analysis on carcass traits of pig carcass.

Nihon Yoton Gakkaishi, 1990
豚枝肉出荷成績の最終的目標を「平均枝肉単価」に置き, 出荷時に得られる各指標を総合的に検討するために重回帰分析の適用を試み, 平均枝肉単価を規制する要因を分析し, 次の結果を得た。1. 平均枝肉単価を構成する要因としては出荷日上物単価, 上物率, 平均枝肉重量の標準偏差の3つが説明変数として有効である。2. これらの説明変数からなる重回帰式の自由度調整済決定係数(R2)は0.967, 回帰からの標準誤差 (Se) は0.963(円) である。3. これら3つの説明変数の平均枝肉単価に対する相対的な寄与の程度を標準回帰係数により求めると, その値の高いのは出荷日上物単価 (0.833) で, 次いで上物率 (0.439), 平均枝肉重量の標準偏差 (-0.158) の順となる。したがって ...

Parameter estimation and assessment of bias in genetic evaluation of carcass traits in Hanwoo cattle using real and simulated data

Journal of Animal Science and Technology, 2023
Most carcass and meat quality traits are moderate to highly heritable, indicating that they can be improved through selection. Genetic evaluation for these types of traits is performed using performance data obtained from commercial and progeny testing ...

Genetic correlations between wool traits and carcass traits in Merino sheep [PDF]

Journal of Animal Science, 2017
Genetic correlations between 29 wool production and quality traits and 14 whole carcass measures and carcass component traits were estimated from the Information Nucleus of 8 flocks managed across a range of Australian sheep production environments and genetically linked.

Genetic parameters for visual scores, growth and carcass traits in Nellore Cattle [PDF]

Anais da Academia Brasileira de Ciências
Growth and carcass traits are essential selection criteria for beef cattle breeding programs. However, it is necessary to combine these measurements with body composition traits to meet the demand of the consumer market.

Genomic heritability and correlation between carcass traits in Japanese Black cattle evaluated under different ceilings of relatedness among individuals

Frontiers in Genetics, 2023
The investigation of carcass traits to produce meat with high efficiency has been in focus on Japanese Black cattle since 1972. To implement a successful breeding program in carcass production, a comprehensive understanding of genetic characteristics and

Effects of carcass weight, sex and breed composition on meat cuts and carcass trait in finishing pigs

Journal of Integrative Agriculture, 2023
Pork cutting is a very important processing in promoting economic appreciation across the swine business chain. The goal of this research is to determine the proportion and weight of meat cuts, as well as to analyze the effects of carcass weight, sex and

USDA yield grades and various carcass traits as predictors of carcass composition

Meat Science, 1985
Twenty-five carcasses from each of three breedtypes (Brahman, Angus and Brahman × Angus) were physically separated into fat, lean and bone. Several muscles from the round and the femur were used to derive equations to predict carcass composition and muscle-to-bone ratio. The femur (as a percentage of the carcass) was shown to predict percentage carcass
