Effects of cassava foliage on feed digestion, meat quality, and antioxidative status of geese

Abstract

As the by-product of cassava, cassava foliage (CF) has been widely used in livestock feed. However, little information is available on its utilization for geese. In this study, we aimed to investigate the effects of CF on the feed digestion, meat quality, and antioxidative status of geese. A total of 108 male Hainan indigenous geese (28-days-old) with similar body weight were randomly and evenly divided into 3 groups, and the geese were fed for 42 D on either the control diet (CON) consisting of ground maize, soybean meal, and wheat bran, or the experimental diet composed of ground maize, soybean meal, and wheat bran supplemented with 5% (CF1) or 10% (CF2) CF. Dietary nutrient digestibility, physicochemical properties, amino acid and fatty acid composition of meat, and antioxidative status of geese were evaluated. The results showed that supplementation of CF in goose diets enhanced the feed digestion and affected the meat quality. In addition, supplementation of CF had beneficial effects on the regulation of amino acid and fatty acid profiles in muscle tissues. Moreover, such supplementation had no significant effect on antioxidative status. Taken together, goose diet containing 5% CF was recommended based on feed efficiency and meat quality.

Effects of Supplemental Feed with Different Levels of Dietary Metabolizable Energy on Growth Performance and Carcass Characteristics of Grazing Naturalized Swan Geese (Anser cygnoides)

“…Janicki et al also reported that semi-intensive feeding resulted in lesser monounsaturated and higher polyunsaturated fatty acids in abdominal fat [ 11 ]. Greater meat L * and b * in CON geese was in line with previous studies of higher breast meat b * and thigh meat L * values in poultry reared in a free-range system [ 23 , 30 , 32 ]. Shear force is used for evaluating tenderness of meat (samples with lower shear force are more tender).…”

“…Geese have a stronger gizzard than other waterfowl, making them successful grazers, able to break down and digest plant cell walls [ 14 , 23 ]. As degradation in the gizzard is largely mechanical, geese that accessed grazing pasture or were supplemented with roughage always had higher relative weights of gizzard and a longer digestive tract.…”

Impacts of Citric Acid and Malic Acid on Fermentation Quality and Bacterial Community of Cassava Foliage Silage

“…CF contains abundant nutrients, especially high levels of crude protein (CP) (16.41-22.68%). CF is widely used in animal feed in many countries, and it has great potential for improving the production performance of animals (Régnier et al, 2013;Napasirth et al, 2015;Li et al, 2017aLi et al, , 2020. Besides, CF harvest is seasonal, with higher quantity biomass in summer or rainy season.…”

Effect of Dietary Protein and Tsaa Levels on Performance, Carcass Traits, Meat Composition and Some Blood Components of Egyptian Geese During the Rearing Period

“…Marcu et al [34] concluded that the increase in dietary protein levels significantly increased in pH values of muscle of broiler chickens. In contrast recently, Li et al [35] reported that using dietary cassava foliage as high protein content for Hainan China geese significantly (p < 0.05) decreased the level of pH 24 postmortem. The present study showed that moderate M + C gave the highest value of pH 24, which linked with meat quality as reported by Biesek, et al [36] who clarified that higher pH of goose meat is often associated with a higher water-holding capacity.…”
