This study aimed to evaluate the Texel lambs’ meat quality fed with increasing levels of crude glycerin (0, 7, 14, and 21% of dry matter) in the diet. Thirthy-two-two non-castrated male Texel lambs were used, with initial weight of 15.9 ± 4.1 kg, using a completely randomized design with four treatments and eight repetitions, per treatment. Upon reaching the average weight of 35 kg, the animals were slaughtered. The meat chemical composition was similar among treatments (P>0.05) and total lipids and crude protein presented averages of 3.47 and 20.05 g 100g -1, respectively. No changes in pH, marbling, color, and water loss under pressure were observed. The shear force did not change among treatments and the texture can be considered soft, with average values of 5.48 kgf. There was a linear (P0.05) were observed for the attributes flavor, tenderness, juiciness, and overall acceptance among treatments. Fatty acids in higher proportions in the meat lamb were to C18:1n-9 (1298.90 mg 100g-1), C16:0 (709.07 mg 100g-1) and C18:0 (433.30 mg 100g-1), with percentages of 42.72, 23.07 and 14.35%, respectively. Significant difference according to the glycerin level in the diet was observed only for the margaric acid (C17:0) with an increasing linear effect, reaching 58.95 mg 100g-1 muscle to the group with 21% crude glycerin, corresponding to 1.77% of total fatty acids. The other fatty acids did not change, and provided a satisfactory result for conjugated linoleic acid (CLA), totaling about 6.1 mg 100 g-1 muscle, corresponding to 0.21% of total lipids. The use of glycerin in the diet for finishing lambs does not alter the characteristics of the meat, maintaining the product quality for consumption.

Background and Aim: Crude glycerin is changed to propionate in the rumen, while chitosan can be used as a feed supplement to increase propionic acid concentration and decrease methane (CH4) production. We hypothesized that supplementation with a combination of a high level of crude glycerin with chitosan could have a beneficial effect on ruminal fermentation and mitigate CH4 production. This study aimed to explore the combined effects of crude glycerin and chitosan supplementation on nutrient digestibility, rumen fermentation, and CH4 calculation in native Thai bulls. Materials and Methods: Four 2-year-old native Thai bulls, weighing 150±20 kg, were kept in a 2×2 factorial arrangement in a 4×4 Latin square design. Factor A represented the incorporation of crude glycerin at 10.5% and 21% of the dry matter (DM) of a total mixed ration (TMR), and factor B represented the supplementation of chitosan at 1% and 2% DM of a TMR. Results: Increasing levels of crude glycerin at 21% decreased DM intake by 0.62 kg/day compared with 10.5% crude glycerin (p<0.05), whereas nutrient digestibility did not change (p>0.05). The incorporated crude glycerin and supplemented chitosan levels did not affect the pH, temperature, concentrations of ammonia-nitrogen, microbial population, and blood urea nitrogen (p>0.05). Supplemented chitosan and incorporated crude glycerin did not show any interaction effects on the molar portions and total volatile fatty acids (VFAs), except estimated CH4. Increasing the incorporated crude glycerin levels increased propionate and decreased the ratio of acetate to propionate ratio, whereas levels of butyrate, acetate, and total VFAs were unchanged. The combination of crude glycerin at 21% in the TMR with chitosan at 2% reduced CH4 estimation by 5.08% compared with the other feed treatment. Conclusion: Increasing incorporated crude glycerin levels in a TMR significantly elevated the propionate concentration, whereas combining 21% crude glycerin in the TMR diet with 2% chitosan supplementation could depress CH4 estimation more effectively than adding one of these supplements alone.
