The adult male Japanese quail has a well developed cloacal gland that produces meringue-like white foam. The physiological significance of the cloacal gland and its foam is still unclear. Therefore, we conducted two experiments to establish the functional role of the cloacal gland and its foam in natural mating and oviducal sperm transport. In the first experiment, artificial insemination of equal numbers of spermatozoa diluted in foam extract and normal saline once in a week were used to determine the role of foam in sperm transport in the female oviduct. After artificial insemination, eggs were collected to measure fertility, the duration of the fertile period, sperm holes and attached spermatozoa in the perivitelline membrane. Higher (P < 0.05) fertility and greater duration of the fertile period were observed when semen was inseminated along with foam extract compared with normal saline. Further, the sperm holes and trapped spermatozoa in the perivitelline membrane were also higher (P < 0.05) in the presence of foam extract. In the second experiment, two males with bigger and smaller cloacal gland areas were allowed to mate with a female. The mating attempts of males with larger cloacal gland were more successful (P < 0.05) than males with smaller cloacal glands. Our results indicated that cloacal foam improves sperm transport in the female oviduct and that males with larger cloacal gland areas are preferred during mating.

A study was conducted to determine the effect of foam extract on sperm motility in the male Japanese quail (Coturnix coturnix japonica). Adult male quails (12 weeks) of heavy body weight strain were housed in individual cages and divided into 5 groups according to the size of their cloacal glands. The data indicated that the size of the cloacal gland was positively correlated with the frequency of foam secretion and total foam production. One gram of freshly collected clean foam was mixed with 1.0 mL of normal saline and homogenized for 10 minutes. After centrifugation at 35 000 rpm, the supernatant was used as 100% foam extract. The extract was diluted to 1:40, 1:20, 1:10, and 1:4 with normal saline to produce 2.5, 5.0, 10, and 25% foam extracts, respectively. 5% foam extract enhanced sperm survival at room temperature (30°–35°C) for 2 to 3 hrs, whereas higher concentrations (10% and above) suppressed sperm motility. From this study, it may be concluded that foam secretion and quantity of foam are directly proportional to the size of the cloacal gland and that the foam enhances and prolongs sperm motility, in vitro at an optimum concentration of 5%.

Reproduction in the Japanese quail ( Coturnix coturnix japonica ) as in many other species, is controlled by the length of the daily photoperiod. The present experiments have investigated the neuroendocrine regulation of both the photoperiodically induced ‘tonic’ gonadotrophin secretion, which causes the development and maintenance of the ovary, and the ‘cyclic’ surge release of luteinizing hormone (LH), which stimulates ovulation. Areas within the anterior and tuberal hypothalamus were destroyed by means of electrolytic lesions while a small knife was used to isolate, to various degrees, the tuberal hypothalamus. Information was obtained on the regulation of ‘tonic’ and ‘cyclic’ secretion of gonado­trophin by using immature and mature laying females, respectively. The results indicate that the neuroendocrine regulation of photo­periodically induced gonadotrophin secretion in immature quail appears to be controlled by two discrete hypothalamic centres, the infundibular nuclear complex (i. n. c.) and the preoptic region (po. r.). The supraoptic region (so. r.) appears to have no influence on photoperiodically induced ovarian development. Deafferentation reveals that afferents from the anterior hypothalamus enter the tuberal region in a diffuse manner from both anterior and lateral directions. As in the developing animals, destruction of either the i. n. c. or the po. r. in mature birds results in a complete block to ‘tonic’ gonadotrophin release and to regression of the ovaries. When the supraoptic region is destroyed, the ‘cyclic’ ovulatory surge of LH is blocked and a polyfollicular syndrome ensues in which the ovaries, still under the influence of ‘tonic’ gonadotrophin release, grow to a very large size, but no ovulation takes place. An intramuscular injection of progesterone stimulates a release of LH in both untreated mature females and in sham-operated females, but not in so. r. -lesioned birds. Priming these lesioned females with oestrogen and progesterone restores, in some birds, the ability to respond positively to progesterone stimulation.
