Abstract

Artificial insemination (AI) with cooled stallion semen has increased markedly during the last decades in all countries, but fertility is often lower than when fresh semen or natural mating is used. The objective of this study was to examine field data (1634, cycles 523 Standardbred (SB) mares, 575 ...

Abstract

The objective of this study was to determine if there are differences in luteal size (LS), progesterone (P4), and luteal blood flow (LBF) between pregnant and non-pregnant Bos indicus dairy cows during the first three weeks after insemination, and whether these parameters are related to each other. ...

Abstract

Background: The aim of this study was to evaluate the reproductive performance of a new artificial insemination (AI) device specifically designed for gilts (Deep cervical AI, Dp-CAI) by means of which the sperm is deposited deeply in the cervix (8 cm more cranial than in traditional cervical ...

AbstractFull Text

Reproductive failures are often difficult to diagnose. However, use of gestation flow charts and sow card information can be very helpful in determining when problems occurred, and which management phases should be examined. Regular returns to estrus after insemination usually are conception...

AbstractFull Text

The objective of the present work was to evaluate the effect of treatment of estrus cycle control (Co-Synch 5 days; J-Synch or Device by 7 days), reproductive status (cyclic or anestrus) and equine chorionic gonadotropin (eCG) on pregnancy rate after fixed time artificial insemination (FTAI). Angus ...

Abstract

Artificial insemination is a technique employed in dogs mainly when natural mating is not possible due to anatomical, behavioral or health problems. This article describes an intravaginal insemination performed in a two-year old Brazilian Mastiff bitch. Vaginal cytology was the diagnostic method of ...

Abstract

In sheep industry, genetic progress rate achieved by artificial insemination (AI) is limited by the convoluted anatomy of the cervix, which does not allow the passage of an insemination catheter for uterine semen deposition. The aim of this study was to test, in 98 pregnant at term Sarda ewes, the...

Abstract

Seasonal variation in artificial insemination (AI) and pregnancy rate in buffalo of small farmers was recorded following analysis of AI carried out in 1087 buffalo in a calendar year. On an average, 90.6±11.1 inseminations were carried out per month and the average pregnancy rate in a calendar year ...

Abstract

The aim of this review is to compare the performance of different reproductive programs using natural service, estrus synchronization treatment before natural service (timed natural breeding (TNB)), artificial insemination (AI) following estrus detection and timed artificial insemination (TAI) in...

AbstractFull Text

Most fixed-time artificial insemination (FTAI) protocols utilize progesterone (P4) as a hormonal source to achieve synchronization of estrus in cattle. The use of an injectable P4 source to control estrus would be an interesting pharmacological strategy owing to the practicality of parenteral...
