Abstract

The number of days (DN) when hens lay fertile eggs as well as the number of fertile eggs (FN) were produced after a single artificial insemination (AI), including the two duration of fertility (DF) traits. Indeed, they are the key production performance that associates with the production cost of...

Abstract

In birds, after natural mating or artificial insemination (AI), sperms are transported through cloaca or vagina at the utero-vaginal junction (UVJ) of oviduct. Only 1% of the deposited sperm passes through the selection process in the vagina to reach the UVJ. In the UVJ, sperm enter the tubular...

Abstract

In this study, whether the secretion of the uterine fluid (UF) exerts a role in the prolongation of functional life-span of the sperm in the hen oviduct was evaluated. The sperm were subjected to upper vaginal artificial insemination (AI) in the vicinity of the utero-vaginal junction (UVJ) under...

Abstract

Glycerol (GLY) and egg yolk (EY) are good cryoprotectants of avian and mammalian sperm, but in birds, they strongly inhibit the eventual fertilization of ova. Using the sperm penetration (SP-holes) assay and fertility trials, the present study investigates (1) the possible mechanism by which this...

Abstract

The method of semen collection and instruments used are described. Ejaculate volume averaged 0.3 ml. (0.15-0.40) and the av. number of spermatozoa per ml. semen was 7 x 109 (6.5 × 109-7.5 × 109); good quality semen was creamy-white and opaque. Up to 91.15% fertile eggs were obtained when the semen...

Abstract

Large-type White turkey hens from a flock with a record of low " fertility " (live embryos at 7-10 days' incubation) were distributed randomly into 4 groups of 50 hens each and were given treatments involving antibiotics and inseminations on a weekly or fortnightly schedule. During the first 5 wks, ...

Abstract

Hens were: (1) naturally mated, (2) inseminated with undiluted semen, or (3) inseminated with semen diluted with an oviduct extract and stored for 6 hr. Egg fertility of group 2 was greater than that of groups 1 and 3 by 6 and 10.13% resp. ; the corresponding figures for hatchability of eggs set...

Abstract

Semen was collected from 8 drakes of the Osaka or Japanese Improved Breed by electro-ejaculation. One electrode was placed on the skin in the sacral region and the other inserted into the vent. An alternating current of 30 volts and 0. 06-0. 08 amps, was applied 3-5 times at intervals of 5 sees,...

Abstract

Semen was collected from 72 cocks during the year Oct. 1948-Sep. 1949. The cock spermatozoon consists of a head, which is needle-shaped, 10 µ long and 1 µ in diameter, and with an acrosome at the tip, a middle piece 5 µ long, and a tail 100 µ long. The av. volume per ejaculate was 0.76 ml. ; it...

Abstract

As A. I. is being used on a large scale at the Poultry Research Centre, Werribee, special techniques have been developed. These are briefly described. Using 0.2 cm. 3 semen diluted 1: 2 with Tyrode solution, fertility of 7175 Leghorn eggs was 82% v. 74.5% of 5272 eggs when 0.l cm. 3 undiluted semen ...
