SIGNS OF APPROACHING PARTURITION

  • Enlargement of mammary gland
  • Vulva swells and becomes soft
  • Thick mucus discharge
  • Animal urinate frequently
  • Animals build nests and beds
  • Loss of appetite
  • The animal becomes restless, lies down, and gets up frequently.

Lactation: This is the release of milk from the udder of a female animal immediately after parturition. The milk contains immunoglobulin and antibodies for the protection of the young against diseases. It is under the influence of hormones such as oxytocin, oestrogen, prolactin, etc. Lactation or milk let-down can be increased, or if the female animal refuses to produce milk, the animal can be injected with oxytocin injection. It will make the animal to secrete milk.
