Using Progesterone Testing To Determine The Right Time To Breed

Rate this post
ovulation time, the tattletale indicator that a grizzle cunt is ovulating and thus ready to breed, is the most coarse thing to go faulty in dog breeding. Poor timing during a cunt ’ s three-week estrus cycle, besides known as estrus, can cause a miss breed and consequence in a normal female being labeled sterile .
“ Knowing when to breed is possibly the most significant expression of breeding. The prime time to breed is 48 to 72 hours post-ovulation, ” says Fran Smith, DVM, PhD, DACT, a board-certified repro-duction specialist, of Smith Veterinary Clinic in Burnsville, Minnesota. “ This is because after ovulation, the released eggs continue to mature, reaching festering two to three days later. Once the growth serve is completed, the eggs are ready for fertilization. ”
progesterone test is used to determine when a backbite ovulates and thus when to breed. A generative hormone, progesterone increases in the bloodstream merely before ovulation. As the progesterone floor increases, lutenizing hormone ( LH ) is released from the pituitary gland, triggering the release of eggs from the follicles .
“ When progesterone reaches 5.0 to 10.0 nanograms ( a measure of one one-billionth of a gram ) per milliliter of blood, a gripe is ovulating, ” Dr. Smith says. “ The preferably the progesterone results are known, the better, since seasonableness is so crucial in breeding. ”

In her veterinary clinic, Dr. Smith uses a progesterone screen that produces results in one hour based on chemilumenescence, or a serve in which lighter is emitted from chemical reactions. The gold criterion is radioimmunoassay ( RIA ) test, which detects the quantitative progesterone grade, though RIA test is typically alone available in veterinary teaching hospitals or large reference laboratories. At-home progesterone kits are available that estimate progesterone levels through semblance changes, though these are not arsenic accurate as chemilumenescence or RIA progesterone testing .
Breeders can combine progesterone testing and behavior monitor to help pinpoint the best time to breed a cunt. Knowing when a backbite ovulates as detected by progesterone testing significantly increases the luck of a successful breed .
“ once you have confirmed ovulation with progesterone examination and know when to breed, you are more likely to get a larger litter size, ” says Dr. Smith. “ You besides will know that a backbite ’ sulfur due date is 62 to 64 days late. ”

Signs a Bitch is Ready To Breed

  • A pinkish, reddish discharge appears during the first week of the heat cycle that gradually turns a tan color during fertility, though some bitches have reddish discharge throughout estrus 
  • The vulva, or two thick folds of tissue at the outer portion of the female reproductive tract, will be swollen and soft at the peak of the heat cycle 
  • Tail flagging, a behavior in which a female stands still while a male investigates her vulva, even wagging her tail from side to side to help a male pick up on her scent, is common 
  • Moody, sensitive behavior, including whining, is common before estrus 
  • Males become keenly interested when they smell the change in a female’s hormones, an indicator she is in her optimal fertile period and ready to breed 

Feeding During Pregnancy
During pregnancy a bitch must not only meet her own maintenance energy requirements but besides those of the growing fetuses. The measure of food she is provided should be gradually increased during the nine weeks of pregnancy.

The increased energy requirement is minimal during the first five weeks of pregnancy due to the small mass of fetal tissues. Feeding her distinctive thermal intake of a andiron food formulated for emergence or all life stages is good during this time .
As the pregnancy progresses beyond the fifth or sixth week, the rapid rate of fetal weave increase leads to a significant increase in a cunt ’ randomness energy requirement. It is estimated that her department of energy prerequisite will increase approximately 10 percentage per week from workweek six to week nine. therefore, at whelping a bitch ’ second energy prerequisite may be closely one and a half times greater than her typical sustenance prerequisite .
During the last three weeks of pregnancy, a brood cunt should be fed two to three times more than ahead pregnancy. little feedings throughout the day of a caloric-dense diet, such as one of the Purina Pro Plan puppy foods or an all life stages food, is recommended. A puppy food besides is recommended for the first separate of lactation. Regardless of the phase of pregnancy, diets should be adjusted based on maintaining an ideal consistency condition for the fraught gripe .
