“…Nowadays, consumers are progressively conscious of the association that the consumption of some fatty acids is good for cardiovascular health. PUFA has a good effect on the health of humans, while on the health of humans, the SFA has adverse effects [51,52]. The present study’s results showed that appropriate amounts of BLTT linearly decreased the SFA and also MUFA, while they quadratically increased C18:3(n−3), these results are in agreements with Tan et al [9] who suggested that dietary addition of tea catechins could reduce the SFA and MUFA and also enhanced the content of C18:3(n−3) in meat of goat.…”

Simple SummaryThe effects of supplementation of branches and leaves trimmed from tea tree (BLTT) on growth performance, rumen fermentation characteristics and meat composition of fattening Nanjiang Yellow goats were studied. Supplementation of 4% BLTT increased final body weight of goats and also increased the activity of superoxide dismutase, while glutathione peroxidase and malondialdehyde followed the quadratic curve. Quadratic curves were also observed for villus height, crypt depth and the ratio of villus height to crypt depth in the jejunum. The quadratic effect was obtained for total essential amino acids, and individual amino acids threonine and leucine. Supplementation of 4% BLTT decreased the saturated fatty acid C16:0, and a quadratic effect was observed for polyunsaturated fatty acid C18:3 (n−3). From the present study, it is concluded that BLTT supplementation has a positive effect on body antioxidative status, gastrointestinal development, rumen fermentation characteristics and overall hence growth performance and meat composition in goats.AbstractThirty-two 6-month-old, healthy Nanjiang Yellow goats (34.6 ± 4.16 kg) were randomly divided into four treatments to evaluate the supplementary effects of branches and leaves trimmed from tea tree (BLTT) on growth performance, rumen fermentation characteristics, and meat composition in fattening goats. The control goats were fed a basal diet. Treatments 1, 2 and 3 were fed 2%, 4% and 6% of BLTT respectively. After a 60 d feeding trial, blood samples were collected for the analysis of the antioxidant profile and goats were slaughtered to obtain the rumen fluid and carcass samples for determination of rumen fermentation characteristics and meat composition perameters. Increased final body weight was observed in goats fed 4% BLTT compared with control. The activity of superoxide dismutase was increased in the 4% BLTT-treated group, while glutathione peroxidase and malondialdehyde followed the quadratic curve. Quadratic curves were also observed for villus height, crypt depth and the ratio of villus height to crypt depth in the jejunum. The quadratic effect was obtained for total essential amino acids, and individual amino acids threonine and leucine. The saturated fatty acid C16:0 was decreased with 4% of BLTT supplementation, and a quadratic effect was observed for polyunsaturated fatty acid C18:3 (n−3). To sum up, our findings revealed that BLTT supplementation has a positive effect on body antioxidative status, gastrointestinal development, rumen fermentation characteristics and overall growth performance and meat quality in goats.

“…Furthermore, the inclusion of lipid fodder in cattle diets can increase the beef content of beneficial fatty acids. Addition of dietary crude glycerol resulted in a 6.08% increase in unsaturated fatty acids in the meat of 22-month-old Nellore bulls (Castagnino et al, 2018). Based on this, future research should examine whether dietary lipid supplementation to Honghe yellow cattle can improve meat quality and taste according to human nutritional needs.…”

RuminantsFull-length research article Comparison of slaughter performances and meat qualities of Honghe yellow cattle at different agesABSTRACT -We examined differences in slaughter performance and meat quality of Honghe yellow cattle of different ages. We randomly selected nine Honghe bulls for slaughter at 12 (12M), 36 (36M), and 60 (60M) months of age. There were significant differences in antemortem live weight, carcass weight, and net weight among the three groups, all of which increased with age. Backfat thickness in 36M (4.77±0.25 mm) and 60M (5.50±0.50 mm) was significantly higher than in 12M (3.00±0.00 mm), and the loin-eye area in 60M (68.02±16.02) was higher than in 12M (27.01±1.89). There was no significant difference in the pH value of the month-old group. Compared with 12M (29.33±4.93%) and 60M (23.87±5.08%), the cooking loss of meat in 36M (36.50±5.07%) was significantly higher; meanwhile, a* value was also the highest in 36M (22.39±1.34), the protein and fat content of muscle in 12M was lower, while the content of meat in 60M was lower. There was no significant difference in muscle ash, Ca, and P contents; the total amino acid and essential amino acid contents of 36M were higher than those of 12M and 60M, and the unsaturated fatty acids of meat in 12M were higher than those in 36M and 60M. The change of age has a certain influence on the slaughter performance and meat quality of Honghe yellow cattle.

“…Montano et al (2015) reported increased weight gain (+ 3.3%) and feed e ciency (+ 12.0%) when crossbred (Brahman, Angus, Shorthorn and Charolais) were nished in feedlot and supplemented with steam-aked corn, distillers dried grains plus soluble and virginiamycin (26 mg/kg of DM) compared to bulls fed a control diet. Castagnino et al (2018) observed increased weight gain (+ 14%) and feed e ciency (+ 14%) in Nellore bulls supplemented with ground corn, soybean meal and virginiamycin (25 mg/kg of DM) compared to bulls fed a control diet. Virginiamycin alters rumen fermentation by increasing proportions of propionate, decreasing lactic acid, methane production and protein degradation .…”

A combination of monensin, virginiamycin and minerals trace could have a synergistic effect on animal performance and meat characteristics of bulls finished in feedlot. This study was realized to evaluate the influence of monensin, virginiamycin, minerals trace and yeast combination on animal performance, feed efficiency, in situ digestibility, feeding behavior, and carcass and meat characteristics from bulls finished in feedlot fed high-grain diet. A total of 36 (European vs. Nellore) bulls at 24 ± 3.2 months of age and with a body weight (BW) of 385.5 ± 3.84 kg were used in a completely randomized design. The four experimental diets were: CONT – without additives; MONE – inclusion of 30 mg of monensin/kg of DM; MOVI – inclusion of 30 mg of monensin + 30 mg of virginiamycin/kg of DM; MOMY – inclusion of 30 mg of monensin/kg of DM + 3.0 g of mineral traces and yeast/100 kg of BW. Final body weight was higher (P < 0.05) for the bulls fed MOVI (558.7 kg) and MOMY (554.6 kg) diets, intermediate for bulls fed MONE (529.3 kg) diet, and lower for bulls fed CONT (514.6 kg) diet. Likewise, the average daily gain was higher (P < 0.01) for bulls fed MOVI and MOMY (2.02 kg/d), intermediate for bulls fed MONE (1.72 kg/d), diet and lower for bulls fed CONT (1.57 kg/d) diets. Dry matter intake and other nutrients were similar (P> 0.05) among treatments. However, feed conversion improved (P < 0.05) for bulls fed MOVI and MOMY diets. Animals fed MOVI and MOMY spent more time ruminating compared to animals fed CONT and MONE (P = 0.034) diets. The carcass weights, carcass dressing and backfat thickness were greater (P< 0.05) for the bulls fed MOVI and MOMY diets. In conclusion, the inclusion of monensin or a combination of monensin + virginiamycin or monensin + mineral trace and yeast resulted in higher animal performance and improved feed efficiency.
