Comprehensive evaluation of production performance and feed quality of ten mulberry varieties for feed in Hainan
This study aimed to screen excellent mulberry varieties suitable for forage application in Hainan and to supplement the protein sources for livestock and poultry in the region.Ten mulberry varieties were selected as test materials to analyze their production performance and feeding quality.The varieties suitable for planting in hot areas were identified through a comprehensive scoring of nutritional factors.The results showed that Gui 5 had the highest yield of fresh leaves,reaching 113 656.80 kg/hm².The second highest yield was Sha 2×Lun 109,92 846.40 kg/hm².The crude protein content in feed mulberry ranged from 19.83%～22.07%,with Sha 2×Lun 109 having the highest content,followed by Gui Sangyou 12.The variety with the highest crude ash content was Sha 2×Lun 109,at 14.69%,followed by Fengchi,at 13.90%.The medium/acid detergent fibers were lower in Jisang,Yu 711,Sangteyou1,and Yuesang 120.The tannin content in the leaves of Jisang was significantly higher than that of other varieties except for Yu 711 and Guisangyou 12.Through factor analysis,the top four scores were obtained by Gui 5,Sha 2×Lun 109,Gui Sangyou 12,and Gui 6.The study indicates that Gui 5,Sha 2×Lun 109,Gui Sangyou 12,and Gui 6 show superior comprehensive performance and can be recommended as feed mulberry varieties for Hainan.
