Summary
Feeding goats Bermuda grass improved meat quality, increasing fat content and tenderness. It also enhanced desirable fatty acids and umami flavor, though caution is advised due to a lower unsaturated to saturated fat ratio.
Area of Science:
- Animal Science
- Meat Science
- Nutritional Science
Background:
- Goat meat quality is influenced by diet.
- Forage type significantly impacts meat characteristics.
- Understanding the effects of specific grasses like Bermuda grass and perennial ryegrass is crucial for optimizing goat meat production.
Purpose of the Study:
- To evaluate the impact of Bermuda grass versus perennial ryegrass on goat meat quality.
- To analyze proximate composition, shear force, fatty acid profile, and flavor.
- To determine the effects on growth performance and nutritional implications.
Main Methods:
- Thirty crossbred goats were fed diets with either Bermuda grass or perennial ryegrass for 4 months.
- Meat quality parameters including proximate composition, shear force, and fatty acid profiles were assessed.
- Sensory analysis (aroma and taste profiling) was conducted.
Main Results:
- Bermuda grass feeding resulted in higher fat content and lower shear force (improved tenderness).
- Increased proportions of linoleic and alpha-linolenic acids were observed in the Bermuda grass group.
- Enhanced umami flavor with reduced sourness and saltiness, alongside higher methanethiol and 2-methylheptanal levels, were noted.
Conclusions:
- Bermuda grass supplementation can enhance specific goat meat quality traits like fat content, tenderness, and flavor profile.
- Dietary inclusion of Bermuda grass may improve fatty acid composition.
- While beneficial for certain quality aspects, the lower unsaturated to saturated fatty acid ratio warrants cautious interpretation regarding overall nutritional benefits.
