Breeding With Chilled And Frozen Semen
Artificial Insemination (AI) involves the introduction of sperm into the reproductive tract of the mare without natural mating. AI in the horse was first practiced long ago. Ancient Arabian texts describe how mares were successfully inseminated. In the late 18th Century, an Italian scientist took the idea up again. He performed a series of studies in which he placed stallion semen in the snow a...
متن کاملSuccessful artificial insemination in the Asian elephant (Elephas maximus) using chilled and frozen-thawed semen
BACKGROUND Artificial insemination (AI) using frozen-thawed semen is well established and routinely used for breeding in various mammalian species. However, there is no report of the birth of elephant calves following AI with frozen-thawed semen. The objective of the present study was to investigate the fertilizing ability of chilled and frozen-thawed semen in the Asian elephant following artif...
متن کاملComparative Study on Conception Rate of Cow in Using Frozen and Liquid Semen
The experiment was carried out at District Artificial Insemination (AI) Center at Khulna to evaluate the conception rate of frozen semen and locally produced liquid semen. Frozen semen from five different genotypes (Local, Sahiwal×Friesian, (Local×Friesian)2×Friesian, (Local×Friesian)×(Local×Frisian×Friesian), Local×Friesian) of bulls was taken which was served by Central Cattle Breeding Statio...
متن کاملFertility of Bull Semen Frozen in Skim Milk Diluent
In Victoria the usual diluent for deep frozen bull semen consists of a mixture of egg yolk, sodium citrate and glycerol. The semen is equilibrated in this mixture for 17 hours prior to freezing. O’Dell and Almquist (1957), and Amman and Almquist (1957) found that survival of spermatozoa as assessed by motility was increased when the semen was diluted with a mixture of glycerol, fructose and ski...
متن کاملEffect of selection for fertility of frozen-thawed semen in chickens on the fertility of fresh and stored semen.
Studies were conducted using 68 males from the seventh generation of a line of meat-type breeder chickens selected for increased duration of fertility of frozen-thawed semen and 69 males of the randomly selected control line. These chickens were used to determine the presence or absence of differences between the selected and control lines with respect to fertility and spermatozoal motility whe...
