Fatty acid composition and carcass traits of 2,275 Japanese Black steers and heifers were analyzed to estimate the heritabilities and genetic correlations using the REML procedure. Slices of LM at the 6th to 7th rib section were minced and homogenized, and total lipids were extracted for the analysis by a gas chromatograph. Oleic acid accounted for the majority (51.3%), followed by palmitic (26.4%) and stearic (10.8%) acids. Heritabilities of carcass traits were moderate to high, ranging from 0… Expand
Estimates of genetic parameters for fatty acid compositions in the longissimus dorsi muscle of Hanwoo cattle.
TLDR
Insight is provided on genetic variability and correlations among intramuscular fatty acids as well as correlations between fatty acids and carcass and meat-quality traits, which could be used in Hanwoo breeding programmes to improve fatty acid compositions in meat. Expand
Estimates of genetic parameters for fatty acids in brisket adipose tissue of Canadian commercial crossbred beef steers.
TLDR
In general, fatty acids such as conjugated linoleic acid and 11t C18:1, with potential health benefits, showed significant antagonistic correlations with unhealthy fatty acidssuch as C14:0 and C16:0, which provide insight into the direct genetic control of host genes on fatty acid composition of beef tissues.

Genetic parameters for fatty acids in intramuscular fat from feedlot-finished Nelore carcasses
The aim of the present study was to estimate covariance components and genetic parameters for beef fatty acid (FA) composition of intramuscular fat in the longissimus thoracis muscle in Nelore bullsExpand
Estimates of genetic parameters for chemical traits of meat quality in Japanese black cattle
TLDR
The results indicate that genetic variance and correlations could exist and be captured for some of the water‐soluble compounds. Expand
Genetic parameters and genetic correlations among triacylglycerol and phospholipid fractions in Angus cattle.
TLDR
The results indicate that fatty acids prominent in beef tissues show significant genetic variation as well as genetic relationships with carcass traits, and heritability estimates differed between the TAG and PL fractions. Expand
Genetic relationships between meat quality traits and fatty acid composition in Japanese black cattle.
TLDR
Positive and stronger genetic correlations were found between BFS and fatty acid composition, in particular, related to the level of unsaturation, which implies that improving the levelof unsaturation makes fat darker (more yellow) and thus requires balancing with BFS. Expand
Genetic correlation estimates between beef fatty acid profile with meat and carcass traits in Nellore cattle finished in feedlot
TLDR
The selection to improve meat tenderness in Nellore cattle should not change the fatty acid composition in beef, so it is possible to improve this attribute without affecting the nutritional beef quality in zebu breeds. Expand
Divergent selection on intramuscular fat in rabbits: Responses to selection and genetic parameters.
TLDR
The response to selection, the correlated responses in carcass and meat quality traits, and their genetic parameters were estimated to be around 5% of the mean per generation. Expand
Effect of selection for intramuscular fat on the fatty acid composition of rabbit meat.
TLDR
The experiment shows that selection for IMF strongly affects the fatty acid composition of meat, due to the high heritabilities of fatty acids and their high genetic correlations with IMF. Expand

TLDR
Using two-trait animal models that treat records from the two sexes as different traits, sex-specific heritabilities and cross-sex genetic correlations which indicate the sex differences in genetic architecture of meat compositions in beef are estimated. Expand

Genetic effects on fatty acid composition of carcass fat of Japanese Black Wagyu steers.
TLDR
The results suggested that genetic factors affected fatty acid composition of carcass fat in Japanese Black Wagyu cattle and that some sires had potent genetic factors affecting this composition. Expand
Effect of breed type and sex on the fatty acid composition of subcutaneous and intramuscular lipids of finishing steers and heifers.
TLDR
It is suggested that the Japanese Black has a genetic predisposition for producing carcass lipids containing higher concentrations of monounsaturated fatty acids than Holstein, Japanese Brown, or Charolais. Expand
Genetic variation in fatness and fatty acid composition of crossbred cattle.
TLDR
Mature Hereford cows (766) were mated to 97 sires from seven breeds, resulting in 1,215 calves born over 4 yr, indicating little evidence of antagonisms between traits that would prevent genetic progress in both production and quality. Expand
Genetic and nutritional effects on the fatty acid composition of subcutaneous and intramuscular lipids of steers.
TLDR
Study on the effects of two nutritional planes [high(H) and medium-high(MH)] on the fatty acid composition of SNL, IMNL and IMPL were done using JB steers, finding that the SNL and IMNL of the H plane steers contained greater percentages of saturated fatty acids at the same CFP but less at theSame SA than the MH plane animals.

The data indicate that beef from purebred Wagyu cattle raised in Japan is enriched in monounsaturated fatty acids, and that the degree of enrichment depends upon the region of Japan from which the samples were obtained. Expand

TLDR
To investigate the genetic factors that affect fatty acid composition of beef, the full-length bovine stearoyl-CoA desaturase (SCD) cDNA from 20 Japanese Black steers was compared and a method for genotyping these two SCD genes based on PCR-RFLP was developed. Expand
Meat fatty acid composition as affected by fatness and genetic factors: a review
TLDR
Although there is potential for genetic change, incorporating fatty acid composition as a goal in classical breeding programs does not seem worthwhile at the present and biochemical and molecular genetic studies should be encouraged to unravel the mechanisms responsible for differences in the metabolism and incorporation of specific fatty acids in meat.

TLDR
It was found that temporary environment was an important source of variation for calving intervals of Japanese Black cows and Random farm effects accounted for approximately 10% of phenotypic variations in all traits. Expand
