SURVEY OF SPECIES COMPOSITION IN THE FAMILY (POACEA) AS FEED FOR LIVESTOCK IN CHIENG NGAN COMMUNE, SON LA CITY, SON LA PROVINCE

Abstract

This study evaluated the species composition and use value of Poaceae plants with potential as animal feed in Chieng Ngan commune, Son La City, Son La province, by traditional botanical methods from carried out from July 2023 to June 2024. The results recorded 46 species belonging to 36 genera. Leaves are the most commonly used part. A total of 46 species are used for cattle and buffalo, 45 species for goats, and 2 species for pigs, with four methods of preparation: direct feeding, drying, cooking, and fermenting. Twelve species have a high utilization value (UI ≥ 0.90). The life form of plants for animal feed is built as follows: SB = 34.78Ph + 21.74Hm + 19.57Ch + 15.22Th + 8.70Cr. There are 5 main geographical factors: the highest is tropical, accounting for 63.04%; endemic to Vietnam, accounting for 15.22%, intertropical element 13.04%, cultivated plants accounting for 6.52% and the lowest is the paleotropic element 2.17%. The habitat of Poaceae plants is mainly with the highest number found in shifting cultivation fields (h) 27 species (accounting for 58.70%), followed by secondary forest (a) 18 species (accounting for 39.13%), grasslands (d) 15 species (32.61%), rice fields (g) 12 species (26.09), home garden (e) with 3 species (6.52%); limestone forest (b) and shrublands (c) with 2 species (4.35%).
