Abstract Estradiol administration increases mammary parenchyma growth and can increase the mass of the mammary fat pad (MFP) in calves. Estradiol can affect fatty acid metabolism, but it is unknown how estradiol affects the fatty acid profile of the MFP and if these effects are consistent across adipose stores. The objective of this investigation was to determine if fatty acid profiles were affected by estradiol administration and if this response is adipose tissue type specific. Holstein heifer calves were reared on a common diet and administered 12 daily injections prior to euthanasia at 82 days of age. Injections were either daily injections of corn oil (n = 4; CON), 9 injections of corn oil followed by 3 injections of estradiol (n = 4; SHORT), or 12 injections of estradiol (n = 4; LONG). Fatty acids were extracted from MFP and subcutaneous adipose tissues samples and analyzed using gas chromatography. Data were analyzed using a mixed model considering the effect of treatment, adipose tissue depot, their interaction, and the random effect of animal. Only significant treatment effects and treatment-adipose type interactions are presented here (Table 1). Estradiol administration (SHORT and LONG) increased total C18:1 fatty acids (P = 0.05), and tended to increase non-C18:2 t10 c12 CLAs, C18:3, and total omega-3 fatty acids (P ≤ 0.1) in the MFP and subcutaneous adipose tissues relative to CON. There was a treatment by tissue interaction for C18:1 trans-10 (P = 0.01), and a tendency for C18:1 trans-11 and C18:2 trans-10 cis-12 (P ≤ 0.1) indicating that estradiol’s effects on fatty acids are tissue specific. Together, these results indicate that the MFP responds differently to estradiol than subcutaneous adipose tissues and that these alterations are associated with different periods of induced mammary growth via estradiol.

Levels of n-6 and n-3 PUFAs, including those with 20 and 22 carbon-chains, in concentrate-fed Asturiana de los Valles (AV) yearling bulls with and without the double muscling gene <I>(mh/mh</I> = 24, <I>mh</I>/+ = 26, +/+ = 25) were measured to examine if this gene influences the pattern of PUFA deposition in different adipose tissues. Fatty acid compositions of muscle tissue (<I>longissimus thoracis</I>) and intermuscular and subcutaneous adipose tissues were determined by gas chromatography. The composition of intramuscular fat was unique compared to the other two adipose tissues which were similar in composition. In general, n-6 and n-3 fatty acid elongation and desaturation products were affected by AV genotype and this effect was most evident in n-3 PUFAs of the intramuscular fat of <I>mh/mh</I> (n-6/n-3 = 11.8 and 18:2n-6/18:3n-3 = 25.3) compared to <I>mh</I>/+ and +/+ animals (mean values of n-6/n-3 = 9.86 and 18:2n-6/18:3n-3 = 15.5). PUFA elongation and desaturation end products did not accumulate to any great extent in intermuscular and subcutaneous adipose tissues. Beef from <I>mh/mh</I> cattle showed greater deposition rates of n-3 elongation and desaturation products but their absolute content of total n-3 fatty acids was lower (21 mg/100 g meat) in comparison with <I>mh</I>/+ and +/+ cattle (mean value of 25 mg/100 g meat).

The present study evaluated the effects of dietary N-carbamylglutamate (NCG) on carcass traits, meat quality, and fatty acid profiles in the longissimus dorsi muscle and adipose tissues of Chinese Ningxiang pigs. A total of 36 castrated female pigs with a similar initial weight (43.21 ± 0.57 kg) were randomly assigned to two treatments (with six pens per treatment and three pigs per pen) and fed either a basal diet or a basal diet supplemented with 0.08% NCG for 56 days. Results showed that dietary NCG reduced shear force (p = 0.004) and increased drip loss (p = 0.044) in longissimus dorsi muscle of Ningxiang pigs. Moreover, increased levels of oleic acid (C18:1n9c) (p = 0.009), paullinic acid (C20:1) (p = 0.004), and α-linolenic acid (C18:3n3) (p < 0.001), while significant reduction in the proportions of arachidonic acid (C20:4n6) (p < 0.001) and polyunsaturated fatty acid (PUFA) (p = 0.017) were observed in the longissimus dorsi muscle of pigs fed NCG when compared with those fed the control diet. As for adipose tissues, the C20:1 (p = 0.045) proportion in dorsal subcutaneous adipose (DSA), as well as the stearic acid (C18:0) (p = 0.018) level in perirenal adipose (PA) were decreased when pigs were fed the NCG diet compared with those of the control diet. In contrast, the margaric acid (C17:0) (p = 0.043) proportion in PA were increased. Moreover, the NCG diet produced PA with a greater proportion of total PUFAs (p = 0.001) (particularly linoleic acid (C18:2n6c) (p = 0.001)) compared with those produced by the control diet. These findings suggest that dietary NCG has beneficial effects by decreasing the shear force and improving the healthfulness of fatty acid profiles, providing a novel strategy for enhancing meat quality of pigs.
