The breeding season of hydra is a critical time for ensuring the survival of fleas. According to statistical data, the general mortality rate during childbirth ranges from 10% to 15%, and approximately 70% to 80% of this mortality occurs within the first five days after birth. This period requires careful attention and timely intervention to improve survival rates.
Preparation before birth is essential. Make sure the nesting area is clean and sterilized. Provide soft bedding and place two layers of mats to prevent newborns from falling to the ground. If a baby falls, it may become cold or injured. Quickly pick it up, warm it with a hot water bottle, and return it to its nest as soon as possible.
When a mother experiences dystocia (difficult labor), she may show signs such as sudden loss of appetite, restlessness, frequent squatting or defecation postures, or licking her vulva. Some mothers may appear scared, leave the birthing box, or look back repeatedly without seeing the baby. In such cases, check if the cervix has opened. If so, administer oxytocin via intramuscular injection—0.3 to 0.6 ml. If the baby is not born within 2–3 hours, consider assisted delivery or a cesarean section. Alternatively, synthetic oxytocin (10 units) combined with 0.3 mg of prostaglandin E2 can be used. The genital area should be disinfected with 0.1% potassium permanganate or levonurin, then a catheter is inserted into the uterine cavity. A syringe filled with the drug solution is connected to the catheter. If no blood or amniotic fluid returns, the solution is injected. If oxytocin fails, the fetus must be removed immediately. The success rate of these interventions can reach 75% to 80%.
After birth, it's crucial to check whether the newborns have consumed colostrum. This isn't just about counting the number of births but also ensuring that each baby has latched onto the mother’s milk. Use a combination of listening, observing, and touching to assess this. Healthy newborns will make strong, consistent squeaking sounds, their noses will be black and shiny, their bellies full, and their umbilical cords dark in color. Those that haven’t eaten colostrum may have pale noses, weak limbs, and yellowish umbilical cords. They may also be scattered around the nest, feel cold, and lack energy.
If a baby hasn’t latched on, check the mother’s nipples. If there’s milk leakage, the surrounding fur might be blocking the nipple. Gently trim the hair around the nipple with scissors to allow the baby access. When checking, keep the process calm, fast, and warm. Avoid unnecessary disturbances and ensure the environment remains quiet to reduce stress on the mother. Also, maintain cleanliness by washing hands before handling the babies to avoid odors that might cause the mother to reject or harm the young. Keep the nests warm to prevent hypothermia, which can lead to pneumonia or other fatal illnesses.
