Growth performance and feed intake of crossbred Bach Thao goat raised in semi - intensive system in Tra Vinh city
This study was carried out from 20th August to 30th September 2020 at experimental farm in veterinary husbandry of Tra Vinh University. Twelve crossbred Bach Thao goats from 5 to 6 month - age was devided into 3 treatments by completely radom method which was supplement mixture concentrated feed in different level of crude protein (16.56%CP, 18.11%CP and 19.22%CP) and repeating 4 times for every treatment. Goats were raised in semi - intensive system and combining with consideration environmental temperature and humidity of house. Result showed that floor and corner barn temperature constant more than outside, arrange from 29.66 to 30.04 celsius degree, especially higher 4.16 percentage with relative humidity at the corner than on floor of house. Generally animal response well for hot climate of location, result show that crossbred goats gain weight from 99.55 to 131.59g/head/day that significantly different between 3 treatmens (P < 0.05). This result indicates that quality of forage in rain reason was better than other so goatsof experiment have achieved suitable growth ability. Forage use efficiency was the best with 19.22%CP treatment (6.85kg dry matter intake/kg moderate weight gain). Simultaneously crude protein consumed/kg moderate weight gain in this of animal was also more efficient than others (0.84kg/kg moderate weight gain). From these results of experiment that can suggest method improve quality of forage on way supplement concentrate feed into diet to increase livestock performance and efficience.
