Meat quality of young bulls finished in a feedlot and supplemented with clove or cinnamon essential oils

The objective of this study was to evaluate the influence a finishing diet containing natural additives fed for 94 days on animal performance, carcass, and meat quality characteristics of crossbred bulls (1/2 Angus × 1/2 Nellore). Forty-eight bulls (initial BW 318 ± 4.7 kg and initial age 22 months) were used in a completely randomised design. Bulls were fed one of four diets: (1) CON – Control; (2) CCO – addition of 4 g/animal.day of a mix of essential oils from castor bean and cashew; (3) MIX – addition of 4 g/animal.day of a mix of essential oils (oregano oils, castor bean, cashew); (4) YST – addition of 4 g/animal.day of yeast. Bulls were finished in feedlot (in individual pens) and slaughtered at an average weight of 469 ± 6.7 kg. Final BW, hot carcass weight and average daily gain were greater (P < 0.05) in MIX diet than in the three other diets. However, DM intake, G : F, fat thickness, longissimus muscle area, marbling, and meat colour were similar (P > 0.05) among the four diets. The carcass conformation score was higher (P < 0.05) for bulls that were fed with the YST diet and similar for the three other diets. Meat from CCO had a reduced (P < 0.05) cooking loss when compared with CON diet. Shear force from MIX diet had lesser values (P < 0.05) than meat from YST diet, and it was similar among CON and CCO diets. There was no diet effect (P > 0.05) on lipid oxidation, moisture, ash, and total lipids contents. C14:0, C14:1 n-9, C16:0, C18:1 n-9, C18:1 n-7 and C18:3 n-6 fatty acids in intramuscular fat from the longissimus muscle were affected by the inclusion of additives in the diets. SFA, MUFA, PUFA, n-3 and n-6 fatty acid percentages, and the ratios PUFA : SFA and n-6 : n-3 were similar (P > 0.05) among diets. In conclusion, adding a mix of oregano, castor bean, and cashew oils in the diet improved the performance of the bulls, but meat characteristics did not significantly change.

The aim of this study was to investigate the effects on meat quality of crossbred bulls finished in a feedlot when some corn is replaced by glycerin and essential oils (EO) are added to the diet. Thirty bulls weighing 311 kg ± 28.8 kg (22 ± 2 months old) were randomly assigned to one of three diets: CON – Control (diet without glycerin and EO); GLY – 16.1% glycerin in dry matter (DM); and GEO – 16.1% glycerin in DM and EO (cashew: Anacardium occidentale; castor: Ricinus communis) at 442 mg/kg DM consumed. The bulls were kept in a feedlot for 115 days and slaughtered at an average weight of 467 ± 27.9 kg (25 ± 2 months old). The bulls were fed on sorghum silage, cracked corn, glycerin, soybean meal, urea, limestone, and mineral salt. Replacing corn with glycerin plus EO adding to the diet had no effect on the fat thickness, Longissimus muscle (LM) area, marbling, texture, colour, Warner–Bratzler shear force, or chemical composition of the LM. The fatty acid composition in the LM was similar among the diets, except for percentages of myristic and margaric acids. The diets had no effect on the percentage of saturated and polyunsaturated fatty acids. Animals fed on glycerin had a lower ratio of n-6 to n-3 in the LM when compared with the CON diet. Partial replacing of corn with glycerin and EO improved meat flavour, tenderness, and the preference of consumers. Corn may be replaced by glycerin to a 15% level of DM without any detrimental effect on the carcass characteristics or the chemical composition of the LM.

Microbial Enumeration

A total of eighty 21-day-olds (1.1±0.01kg) ROSS 308 broilers were randomly allocated into 4 groups, with 20 replicates per group and 1 chicken per replicate per cage. Three experimental groups (CAR, THY, ORE group) were given oral administration of 200ìL essential oils (carvacrol, thyme and oregano) at 18:00h every day. The results showed no significant differences on blood metabolites among each group (P>0.05). The villus height of the small intestines in the CAR group increased significantly (P less than 0.05) from 1360.10 to 1552.54ìm as compared to the control group, the goblet cell counts in the THY and ORE groups significantly increased by 20.91% (P less than 0.05) and 31.82% (P less than 0.05), respectively, compared to the control group. The E.coli and Salmonella in ORE group significantly decreased by 11.16% (P less than 0.05) and 9.54% (P less than 0.05), respectively, compared to the control group. The Redness (a*) values of the muscles of the CAR and ORE groups were observed to increase significantly (P less than 0.05) from 3.58 to 7.95 and 6.86, respectively, compared to the control group. In conclusion, oral administration of the essential oils carvacrol, thyme, and oregano promoted intestinal development, improved the intestinal environment and the meat quality of broilers.
