Abstract

SEMEN was obtained from 12 F2 Bronze ♂ × White Holland ♀ hybrid ♂♂. The quantities varied from 0.1-0.7 c.c., but the majority of ♂♂ yielded 0.3-0.4 c.c. The semen is more viscous than that of the domestic cock and is yellowish white in colour. Four groups, each of 8 turkey hens, were inseminated...

Abstract

THE method of artificial insemination with mixed semen from several ♂♂ is considered expedient for achieving improvement of egg production by heterosis, as it ensures a constancy of the genetic constitution of those populations within pure breeds which have proved suitable for such improvement....

Abstract

COCK sperm was obtained by electro-ejaculation (D.C., 4 volts), one terminal being introduced subcutaneously in the region of the 3rd lumbar vertebra, the other inserted into the cloaca. The current was passed for periods of 3 sees., with intervals of 6 sees., and ejaculation usually occurred after ...

Abstract

BROWN and White Leghorns were artifically inseminated with normal semen, dead stained sperm, or carbon particles, and after various periods killed and smears of various parts of the oviduct examined. It was found that the sperm could reach the ovary in about 26 mins. If, however, an ovum was in the ...

Abstract

This investigation reports the results obtained from artificial insemination of 257 hens with mixed semen from 30 cocks. The semen was either given undiluted or diluted with Ringer solution; 30% semen gave better results than undiluted semen, and 10% semen gave as good results as undiluted semen....

Abstract

THE Secretary for Agriculture and Forestry reports on the situation created by war conditions and the developments in agricultural policy in response to them. As yet there has been no serious effect on agriculture and the Department has proceeded with its fundamental work in a fairly normal manner. ...

Abstract

THE number of completed copulations by New Hampshire ♂♂ during a 15-min. trial period after a 36-hr, rest period ranged from 0 to 5, and averaged 1.26. Incompleted attempts (without ejaculation) ranged from 0 to 3 and averaged 0.19. The volume of 192 ejaculates obtained with the semen collector...

Abstract

COMPOSITE samples of semen from 6 Barred Rock ♂♂ were used to investigate the effects of osmotic pressure, viscosity of media, and t° on viability of spermatozoa. Dehydration by dilution with 0.5 to 0.75 M. laevulose solution appeared to lengthen the life of the spermatozoa (266-290 hrs.' storage)...

Abstract

II. The abdominal massage method of semen collection [see Burrows and Quinn, A.B.A., 3: 291) is satisfactory for purposes of biological research and artificial insemination. The volume of semen ejaculated was generally directly related to the length of the sexual rest of the ♂. Average figures for...
