Abstract

In experiment 1, 16 rows, each of 15-20 individually caged White Leghorn ♀♀, were artificially inseminated intravaginally at 8 a.m., 1 2 noon, 4 p.m., or 9 p.m with 0.05 ml of undiluted pooled semen from 10 cockerels. In experiment 2, hens in 28 colony cages, each of 4-6 ♀♀, were inseminated with...

Abstract

Two experiments were conducted, each with 3 groups of approx. 70 individually caged White Leghorn pullets that were artificially inseminated at 8 a.m., 4 p.m. and 11.50 p.m. on different days. The ♀♀ were exposed to 14 hr of light daily. The hens that laid during the first 1-4 hr after insemination ...

Abstract

Results from experiments in which Beltsville Small White turkey hens were artificially inseminated with semen from tonas of B. S. W., Broad-Breasted Bronze and Black varieties show that 1 double insemination (inseminations on 2 successive days) of semen from 1 variety of toms following previous ...

Abstract

Earlier work (see ABA 39, 1198) had shown that the reduced fertility observed following insemination, natural or artificial, near the time of oviposition, is not due to the physical presence of an egg in the uterus. In the present work, hens without hard-shelled eggs in their uteri were injected...

Abstract

No significant correlation was observed between, the % fertility of eggs laid by artificially inseminated turkey hens and the amount of semen used. Inseminations were made at 3-weekly intervals with doses of mixed, undiluted semen varying from 0.005 cm.3 to 0.10 cm.3 The egg fertility of birds...

Abstract

Results reported in this paper indicate that higher fertility and hatchability were obtained when hens were artificially inseminated in the late afternoon than when insemination took place in the early morning or at noon. This higher fertility and hatchability were shown to be related to the fact...

Abstract

RHODE Island Red pullets were divided into 3 approx. equal groups, group I being artificially inseminated in the early morning, group II at noon, and group III in the late afternoon. Each bird was inseminated once with 1 cm.3 mixed semen from the same ♂♂; and 869 eggs were incubated. Fertility was...

Abstract

DATA were collected from Broad-Breasted Bronze turkeys from Jan. to mid-June; they had been hatched the previous season and were mated naturally in 1945 and artificially inseminated in 1946. In 1946 more intense artificial lighting was used from 3rd Jan. to give 14 hrs. light per day; laying...
