Understand the Problem
The question includes a list of multiple-choice questions related to veterinary reproductive physiology, particularly concerning female dogs (bitches) and their pregnancy, as well as contraceptive methods. The aim is to assess knowledge on specific facts and concepts within this field.
Answer
An early luteotropic factor is prolactin. Diestrus lasts 63 days. Progesterone 8 ng/ml indicates ovulation. Transfusions are intravenous. Neutersol is irreversible contraception. Flare-up with deslorelin. Wean puppies at 6 weeks. Pregnancy is ovulation to parturition. SIPS is a vaginal disease.
The final answer is: An early luteotropic factor in female pregnancy is prolactin. The diestrus phase in pregnant bitches lasts for 63 days. Progesterone 8 ng/ml and 90% of the superficial cells in the vaginal cytology mean that an ovulation has occurred. Blood transfusion in puppies should be performed intravenously. An irreversible form of contraception is neutersol. The flare-up effect is observed after the use of deslorelin. Puppies should be weaned at 6 weeks. Physiological duration of pregnancy in a bitch means the period from ovulation to parturition. SIPS is a vaginal disease.

More Information
Prolactin is crucial for maintaining the corpus luteum in dogs, essential for pregnancy. Intravenous blood transfusions ensure proper distribution. Weaning at 6 weeks supports independent feeding. Deslorelin's flare-up effect involves an initial hormone surge.
Tips
Be careful to distinguish between natural luteotropic factors and pharmaceuticals that mimic their effects. Misidentifying the hormonal phases can lead to errors.
