Selection of High-yielding Tree and Grass Species for Cattle Feed Suitable for Ecological Conditions in Ha Giang

Abstract

With an advantage of relatively wide area, diversified terrain, Ha Giang province is considered to have a great potential to develop grass-fed livestock. However, in Ha Giang, there are now many difficulties in ensuring the provision of green food for cattle, especially in cold winter season. In order to contribute to the development of livestock feed supply in the area, this study aims to select suitable tree and grass species for ecological conditions in Ha Giang, contributing to the sustainable development of livestock in the area.

Selected research results from 11 plants and grass varieties, including: VA06; Panicum maximum TD58; Guatemala; Brachiaria Brizantha, B. Mulato II; The Florida Elephant; Pakchong; Maize NK4300; Maize LCH9; local Sorghum in Lao Cai; imported Sorghum BMR6 shows that Pakchong, VA06, TD58 and maize variety NK4300 have good growth and yield. The Pakchong elephant grass is capable of yielding 188.6 tons / ha / year, VAO6 177.8 tons / ha / year, Panicum maximum TD58 is 126.6 tons / ha / year and maize variety NK4300 was 70.4 tons / ha / 2 crops of Summer and Autumn.

Based on the results of field experiments, the study has selected the Pakchong elephant grass, VA06, Panicum maximum TD58 and maize variety NK4300, which have good growth, high yielding and suitable for the ecological condition in Ha Giang province.
