Qualitative traits of aged m. triceps brachii and m. gluteus biceps from lambs on supplemented feed

Abstract

The aim of this study was to evaluate the effect of the supplementation and aging in the gluteus biceps and triceps brachii muscles of lamb. Forty-eight Santa Inês lambs, with 15 kg average initial weight were slaughtered at 32 kg average final weight, after five months of supplementation. Twenty-four animals were allocated to sixteen pastures with residual leaf area index (2.6) and unsupplemented, the other twenty-four animals were allocated to the same conditions but were supplemented. The treatments were cross factorial between rLAI (2.6) and supplemented or not, totalizing 8 treatments. In this experiment, the slaughter criterion was the age of the animals. In the gluteus biceps and triceps brachii muscles, storage for seven days increased lipid oxidation. The values of cooking loss and water holding capacity increased with time of aging and were higher in the gluteus biceps, by 29.40% and 71.30%, respectively. The supplementation implies an increase in production costs, but its use provides the quantitative and qualitative characteristics favorable to the product, aiming to satisfy the consumer market. The supplementation decreased the shelf life, increasing the lipid oxidation during time of aging and affected the lightness and the hue of yellow, which may sffect consumers' intention to purchase.

Regioselective C–H Thiocyanation of Arenes by Iron(III) Chloride Catalysis

“…The iron(III)-catalyzed thiocyanation reaction was also investigated for the efficient synthesis of biaryl ether 12 , which is a key intermediate for the synthesis of toltrazuril ( 13 ), used to treat coccidiosis in livestock and poultry. 19 We proposed that an iron(III)-catalyzed thiocyanation could be used for a two-step synthesis of 12 from 2-methyl-4-nitro-1-phenoxybenzene ( 10 ) ( Scheme 3 ). Initial attempts at thiocyanation of 10 demonstrated that a 10 mol % catalyst loading of iron(III) chloride was required for good conversion.…”

Technologies Used in Production Systems for Santa Inês Sheep: A Systematic Review

“…The effect of protein-energy supplementation on carcass characteristics of sheep has also been verified. Nevertheless, despite favoring meat characteristics, this type of supplementation may increase lipid oxidation during the aging time and affect consumer acceptance ( 110 ). However, protein-mineral supplementation could improve the quantitative and qualitative carcass characteristics ( 120 ).…”

Trifluoromethylthiolation of Arenes Using Lewis Acid and Lewis Base Dual Catalysis

“… 2 Consequently, the trifluoromethanesulfenyl group is a valuable motif for agrochemical and pharmaceutical discovery. Several bioactive CF 3 S-containing compounds are commercially available and include toltrazuril ( 1 ), 3 used to treat coccidiosis in livestock and poultry, and the anorectic drug, tiflorex ( 2 ) ( Figure 1 ). 4 Trifluoromethanesulfenyl analogues of losartan (e.g., 3 ) have also been developed as potential hypotensive agents.…”
