[Tóm tắt] Luận án Đánh giá khả năng thích ứng của giống cừu Phan Rang nuôi ở Thừa Thiên Huế

<p> 1. Conclusion Phan Rang sheep have existed and adapted to characteristic of dry – hot temperature, high average temperature and low humidity of Ninh Thuan over a hundred years. When Phan Rang sheep were raised in Thua Thien Hue’s conditions with generally particular weather cold -humid; cold- humid in Winter, hot- dry in Summer; Temperature and THI of Thua Thien Hue were lower than those of Ninh Thuan; Vice verse, Humidity of Thua Thien Hue was higher than that of Ninh Thuan; The following conclusions were reached initially: 1. Physiological indicators (rectal temperature, heart rate, skin temperature, red blood cell, hemoglobin, hematocrit and white blood cell) of sheep raised in Thua Thien Hue were no different compared to in Ninh Thuan; whereas, respiratory rate was higher (14.54 breaths/min), however, they were still within sheep’s generally physiological range. Temperature, humidity and THI correlated closely with respiratory frequency (R2: 0.73-0.82) and hemoglobin content (P<0.05). Sheep’s physiological parameters increased remarkably (P<0.05) in data of Temperature >29.50C, THI >28.5 and humidity <75%. </p>
