Abstract

A semen extender (ID-2) containing N-tris (hydroxymethyl) methyl-2-aminoethane sulphonic acid 1.2 g, anhydrous dextrose 3.2 g, tris hydroxymethyl aminomethane 0.36 g, citric acid 0.076 g, sodium lauryl sulphate 40 mg, caffeine sodium benzoate 8 mg, amikacin sulphate 4 mg dibakacin sulphate 4 mg and ...

Abstract

Boar semen was diluted in 7 diluents (egg yolk-glucose-citrate, Beltsville L1, Purdue extender, IVT, and 3 variants of IVT), and was frozen. Post-thawing sperm survival was best with Beltsville L1 and IVT variant 4G-2B. Data are tabulated on the release of the 2 enzymes by spermatozoa before...

Abstract

The method used by the Japanese in the artificial insemination of pigs is described. Practical details are given about the properties of boar semen, its collection, dilution and storage, and the technique of insemination.
The av. duration of ejaculation in the boar is 6 mins. 36 secs. The part of...

Abstract

The optimum concentration of sodium citrate in the diluent was 3. 0-3. 5% when it involved 11 molecules of combined water and 2. 5-3. 0% when it involved 2 molecules. It was approx. 0. 1 mol in concentration and 1. 015 in specific gravity in both cases. The freezing point depression most suitable...

Abstract

The concentration of milk powder suitable for the survival of boar spermatozoa was 10% for whole milk and 8% for skim milk. There was no difference between whole and skim milk powder in their effect on sperm survival, but the latter gave better sperm visibility under the microscope and was cheaper. ...

Abstract

In order to determine the correct amount of semen to be used in the artificial insemination of pigs, 283 experiments with 232 sows were made. The volume of semen normally necessary for successful conception was estimated to be 50 em.3; where the sperm concentration was high and the semen had been...

Abstract

THE minimum quantity of semen normally required for conception is 50 cm.3, but if the semen is of high sperm density and stored for less than 24 hrs., 30 cm.3 will be sufficient. The number of spermatozoa necessary for conception is, in the case of under 24 hours' storage, 5 billion; when stored...

Abstract

THE quantity of semen per ejaculate is 225.7 (65-680) cm.3, 178.8 (38-580) cm.3 being liquid and 46.9 (10-205) g. gelatinous. The pH of fresh semen is 6.4-7.4 and the sp. gr. 1.0075-1.025. The temperature of freshly ejaculated semen is lower than the body temperature by 0.3°-4.1° C. The volume of...
