The peroxisome proliferator-activated receptor gamma (PPARγ) gene plays an important role in the biosynthesis process controlled by a number of fatty acid transcription factors. This study investigates the relationships between 130 single-nucleotide polymorphisms (SNPs) in the PPARγ gene and the fatty acid composition of muscle fat in the commercial population of Korean native cattle. We identi...

The objective of this study was to compare carcass and meat quality between Barbarine lambs raised on rangelands and those reared indoors. A total of 24 weaned male lambs (23.2 kg) were allotted into two groups. The first group (GS) grazed pasture dominated by natural shrubs and was supplemented with 100 g of concentrate. The second group (HS) received oat hay and 200 to 300 g supplement of the...

Effects of L-carnitine administration via drinking water on growth performance, carcass traits, blood serum parameters and abdominal fatty acid composition of ducks was examined. One hundred day-old Turkish native duck chicks were divided into two groups, each with five replicates and given the same diets with 0 and 200 mg/l carnitine chlorhydrate via drinking water. The study lasted 8 weeks, w...

A study was conducted to determine the effect of conjugated linoleic acid (CLA) synthesized from sunflower oil on growth, carcass characteristics and meat quality of heavy pigs. Thirty-six pigs, half barrows and half females, averaging 97 kg L.W., allotted within weight and sex to a randomized complete experimental design, were fed diets supplemented with different CLA levels: 0.5% lard (C), 0....

Fifty 3-month-old male Tan lambs (similar in body weight) were divided into 5 groups to investigate the effects of different restricted pasture grazing times and indoor supplementation on the productive performances and fatty acid composition of the intramuscular fat in growing lambs. The lambs grazed for different periods of time (12 h/d, 8 h/d, 4 h/d, 2 h/d, and 0 h) and received various amou...

Thirty-six castrated male growing pigs were used to study the effect of dietary beef tallow (BT) versus sunflower oil (SO) on meat quality and fatty acid composition of various tissues. The diets used contained either 5% (w/w) of the variable fat source. The fat type had no significant effect on carcass traits (carcass weight, back-fat thickness, fat-lean ratio) and meat quality (colour, pH(1),...

A six-week experimental trial was conducted to evaluate the effect of feeding different levels RDDGS in commercial broiler chicken on carcass traits, chemical composition, and fatty acid profile meat. total 144 birds were divided into four treatments three replicates each with 12 fed at inclusion 0% (T1), 5% (T2), 10% (T3) 15% (T4). All rations nearly isocaloric isonitrogenous. One male one fem...

The effects of dietary crude glycerin on growth performance, carcass characteristics, meat quality indices, and tissue histology in growing pigs were determined in a 138-d feeding trial. Crude glycerin utilized in the trial contained 84.51% glycerin, 11.95% water, 2.91% sodium chloride, and 0.32% methanol. Eight days postweaning, 96 pigs (48 barrows and 48 gilts, average BW of 7.9 +/- 0.4 kg) w...

introduction: cholesterol and fatty acids are two important components of the lipids. various fatty acids have different effects on plasma lipoproteins. consumption of saturated fatty acids tends to increase total plasma and ldl cholesterol levels. while  polyunsaturated fatty acids reduce both ldl and hdl cholesterol, edible oil rich in monounsaturated fatty acid (mufa) however, tend to lower ...

The impact of feeding flax as seed, meal, or oil to late-pregnant and lactating sows on fatty acid profiles in sows and their piglets was studied. Sixty second- and third-parity sows (Yorkshire x Landrace) were fed 1 of 4 diets from 68 d of gestation until 21 d of lactation. Diets were: control without flax (CTL, n = 15); 10% flaxseed supplementation (FS, n = 16); 6.5% flaxseed meal supplementa...
