The impact of acetyl salicylic add (ASA) on reproductive performance during periods of heat stress was studied in Japanese quail (Coturnix coturnix japonica). During a season when daily high temperatures averaged between 34 and 40 degrees C, four treatments each containing four replicates of five males and five females were given 0, 0.5, 1.0, or 1.5 g/L ASA in drinking water from 34 to 45 wk of age. At 39 wk of age control quail were lighter than quail fed ASA. Quail receiving 1.5 g/L ASA exhibited increased fertility, hatchability, and egg production and decreased late dead and total embryonic mortality. Early dead embryos, pips, chick weight, and egg weight were not different among treatments. The lumen of uterovaginal junction sperm host glands (UVJSHG) from control quail was apparently devoid of spermatozoa, whereas quail receiving 1.5 g/L ASA had the greatest apparent accumulation of spermatozoa. Control caudal infundibulum host glands (CPOI) were devoid of spermatozoa in contrast with CPOI from quail receiving ASA. Results show that UVJSHG lumens from quail receiving 1.5 g/L ASA had larger inside diameters than other treatment groups. However, the CPOI inside diameter and the outside diameters of both UVJSHG and CPOI were not affected by ASA. Adding 1.5 g/L ASA to the drinking water of quail under heat stress improved body weight, fertility, hatchability, embryonic mortality, egg production, egg specific gravity, and sperm storage capacity.
研究了乙酰水杨酸(ASA)对处于热应激期的日本鹌鹑(Coturnix coturnix japonica)繁殖性能的影响。在日高温平均在34至40摄氏度的季节,从34至45周龄,将四个处理组(每组包含五个重复,每个重复有五只雄性和五只雌性)的饮用水分别添加0、0.5、1.0或1.5 g/L的ASA。在39周龄时,对照鹌鹑比饲喂ASA的鹌鹑体重轻。接受1.5 g/L ASA的鹌鹑繁殖力、孵化率和产蛋量增加,晚期死亡和总胚胎死亡率降低。处理组之间早期死亡胚胎、啄壳、雏鸡体重和蛋重没有差异。对照鹌鹑子宫阴道连接处精子储存腺(UVJSHG)管腔明显没有精子,而接受1.5 g/L ASA的鹌鹑精子明显积累最多。对照尾端漏斗储存腺(CPOI)没有精子,而接受ASA的鹌鹑的CPOI则有精子。结果表明,接受1.5 g/L ASA的鹌鹑的UVJSHG管腔内径比其他处理组大。然而,CPOI内径以及UVJSHG和CPOI的外径不受ASA影响。在热应激条件下,向鹌鹑饮用水中添加1.5 g/L ASA可改善体重、繁殖力、孵化率、胚胎死亡率、产蛋量、蛋比重和精子储存能力。
