This study aimed to identify the relationship between temperature (T), humidity (H), temperature-humidity index (THI) and water intake (WI) and growth factors in lamb. There were 20 Phan Rang lambs belonging to four age groups of 3, 6, 9 and 12 months (5 heads per each group) were raised in Thua Thien Hue province, Vietnam, in different seasons by T and THI were examined and WI and growth hormone (GH), Insulin-like growth factor 1 (IGF-1), with its cellular transport and receptor proteins GHBP, GHR, IGFBP, IGFR -1) for two seasons: hot (June-August) and cold season (November-January). Daily T, H and WI were recorded, and the reason for IGF-I was determined. The results showed that T, H, THI and WI were closely correlated (P<0.05) with IGF concentration. When the T was 26.30C to 32.50C and increased by 10C, the WI increased by 0.46 litre/day/lamb, and the concentration of GH and IGF-I in the blood also changed ng/ml. When the value of THI was more than 25.6 and rose by one value, the WI was increased by 0.45 litre/day/lamb and growth hormone (GH) and IGF-I (by ng/ml was increased as well (P < 0.01). Humidity tends to be the opposite; when humidity is below 75%, the amount of water consumed does not change and GH in balance; when humidity is above 75%, for every 10% decreased the WI, but increased GH in balance for growth performance, the amount of water consumed decreases by 0.46 litres/day and GH ng/ml in lamb.
本研究旨在明确温度(Temperature, T)、湿度(Humidity, H)、温湿度指数(Temperature-Humidity Index, THI)与采水量(Water Intake, WI)及羔羊生长因子之间的关联。试验选取越南承天顺化省饲养的20头潘朗羔羊,按3、6、9、12月龄分为4个组别,每组各5头,于不同季节开展饲养试验,分别在热季(6-8月)与冷季(11-1月)测定相关指标,包括温湿度、采水量,以及生长激素(Growth Hormone, GH)、胰岛素样生长因子1(Insulin-like Growth Factor 1, IGF-1)及其细胞转运与受体蛋白:GH结合蛋白(GHBP)、生长激素受体(GHR)、胰岛素样生长因子结合蛋白(IGFBP)、胰岛素样生长因子-1受体(IGFR-1)。每日记录温湿度与采水量,并检测IGF-I相关指标。结果显示,温度、湿度、THI与WI均与IGF浓度呈显著相关(P<0.05)。当温度处于26.3℃至32.5℃区间时,温度每升高1℃,每头羔羊的日采水量增加0.46升,血液中GH与IGF-I浓度亦发生变化(单位:ng/ml)。当THI高于25.6时,该指数每升高1个单位,每头羔羊日采水量增加0.45升,血液GH与IGF-I浓度同样显著升高(P<0.01)。湿度的影响则呈相反趋势:当湿度低于75%时,羔羊采水量与血液GH水平均保持稳定;当湿度高于75%时,湿度每降低10%,羔羊日采水量减少0.46升/日,血液GH浓度升高以优化生长性能。
