Abstract

Semen of White Leghorn and Rhode Island Red males was stored for 24 h in diluents hypertonic (460 mOsm/kg H2O) and isotonic (340 mOsm/kg H2O) to cock seminal plasma. 2. Compared with the fertility results with semen that had been stored in the hypertonic diluent or was fresh, the fertility of the White Leghorns was not affected after storage in the isotonic diluent; a decrease (P less than 0-05) was observed, however, using Rhode Island Red semen and isotonic diluent. 3. Fresh RIR semen contained 2-3% "neck-bent spermatozoa" (NBS) which was increased to 4-23% and 5-76% after dilution in hypertonic and isotonic diluents respectively and stored for 24 h. It is doubtful whether this increase (P less than 0-05) is the sole reason for the lowered fertility obtained with this breed after storage in the isotonic diluent.

摘要

将白来航鸡和洛岛红鸡雄性的精液在相对于公鸡精浆为高渗（460 毫渗量/千克 H₂O）和等渗（340 毫渗量/千克 H₂O）的稀释液中保存 24 小时。2. 与保存在高渗稀释液中的精液或新鲜精液的受精结果相比，白来航鸡的精液保存在等渗稀释液中后受精能力未受影响；然而，使用洛岛红鸡精液和等渗稀释液时，受精能力出现了下降（P 小于 0.05）。3. 新鲜的洛岛红鸡精液含有 2% - 3%的“颈部弯曲精子”（NBS），在高渗和等渗稀释液中稀释并保存 24 小时后，分别增加到 4% - 23%和 5% - 76%。这种增加（P 小于 0.05）是否是该品种精液保存在等渗稀释液后受精能力降低的唯一原因，尚值得怀疑。
