We can now offer in-house quantitative progesterone levels, and continue also to offer Premate estimation. Please ask us for advice choosing the best option for your bitch.
Premate is a test performed in our practice laboratory to measure the hormone progesterone in the blood of your bitch when she is in oestrus (heat or season).The level of progesterone is important in predicting the best time to mate to achieve optimum litter size.
This can be especially helpful in bitches who failed to hold to a previous mating, and for ones which have to travel a significant distance to the stud dog. The level of progesterone drops below a certain level 24 to 48 hours before whelping and so also gives us an idea when to expect the bitch to give birth.
The following is the detailed application/interpretation of this test – don`t worry about the detail – the vet will help with all of this!!
- Premate – accurately predicts ovulation, so it`s use: Aims to get more than 90% fertility aims to consistently increase litter size because they predict ovulation, the progesterone levels are superior to vaginal smears (which are still very valuable as they can predict standing oestrus (at 66% cornification). If your bitch is genuinely on heat, and smears/timing suggest standing oestrus is imminent, then Premate testing can help:
- Mating – remember 1/3 rd of bitches don`t ovulate when you expect them to!!
Premate Testings Results
- Prog < 3ng/ml – ovulation NOT imminent – retest 2-3 days later
- Prog between 3 and 10 ng/ml – Ovulation imminent – retest 1 day later
- Prog >10 ng/ml Bitch has probably ovulated – mate/inseminate immediately
- Prog = 10 ng/ml – probably just ovulated – mate/inseminate in 1-2 days
Please ask for pricing structure – these vary between breed and clinical situation
Whelping – when is she due?
Sometimes it is desirable to know exactly when a bitch is due eg. in Bulldogs when we almost expect to perform a Caesarian section.
Premate testing can assist:
- Prog < 3ng/ml – Ready to whelp 24-48hrs
- Prog between 3 and 10 ng/ml – Retest 1 day later
- Prog >10 ng/ml Not yet ready – retest 2 days??
Canine Herpes Vaccination
An important cause of apparent infertility or of “Fading Puppy Syndrome”
Breeder Services Maximising litter viability Canine Herpes Vaccination
This vaccine can effectively prevent these problems, and can dramatically increase litter size and viability – we strongly recommend this to all our breeders. The first injection is given soon after mating, and a second 6-7 weeks later.
Pregnancy Diagnosis in The Bitch
- The vet can examine the abdomen by careful manual palpation – this is easiest from day 21-24 – the biggest source of error in this technique is associated with small litter sizes, and/or tense abdominal muscles.
- We can also perform a pregnancy ultrasound scan using our dedicated sector scanner – this is best done between day 28 and 32. We will not predict exact litter size for you – sound bounces around and false echoes can be misleading!!
- In rare cases when doubt still remains, a blood test based on serum relaxin can be performed to confirm a pregnancy (best from day 28).
- Intrauterine parasite control – all pups get worms from mum, even before they are born and in the first few days of life – we strongly recommend pre-treating mum during the last third of her pregnancy – ideally from day 42 post-mating.
