BREEDING SEASON of FARM ANIMALS In many species, the breeding activity of a female is affected by the seasons of the year. Such species are called Seasonal Breeders. The period of the year when the breeding activity of females of a species is maximum is termed as Breeding Season. Monoestrus Animals These are those animals that show heat signs only once during their breeding season. An example of a Monoestrus animal is Bitch. Polyester Animals These are those animals that show heat signs more than once during their breeding season. Examples of Polyestrus animals are sheep, goats, mare, etc. Short-Day Breeders These are species in which breeding activity increases as the day length decreases. Typical examples of Short-day breeders are Sheep and Goats. Long-Day Breeders These are species in which breeding activity increases as the day length increases. A typical example of a Long-Day breeder is Mare. Sheep & Goats In sheep & goats, the breeding season is autumn....
Puberty Derived from the Latin word “pubscere” means covered with hairs. Puberty is the stage when an animal is able to release viable gametes (ova in female and spermatozoa in the male) and shows complete sexual behavior sequences. In a female, puberty is the age when the first estrus accompanied by ovulation occurs and females can support pregnancy without any deleterious effects. The ability of females to ovulate, conceive, and carry the pregnancy. In a male, puberty is the age when first time ejaculated with a threshold number of spermatozoa enough for successful fertilization and manifest sexual behavior. It occurs when an animal has reached a critical somatic development (Bodyweight) for each species or breed. At puberty, an animal attains about 60% of its mature body weight. Initiation of puberty is a function of animal age and body weight. During the pre-pubertal period, the gro...
Anatomy And Physiology Of Reproductive System : Female reproductive tract of various farm animals are similar to the cow but differ primarily in the shape of uterus and cervix. Female tract consists of : ➤Vulva ➤Vagina ➤ Cervix ➤Uterus ➤Uterine Horns ➤ Fallopian Tube ➤Ovaries Vulva Exterior portion and opening of the female reproductive tract. The vulva is the exterior opening of the reproductive and urinary system. The exterior and the visible part of the vulva consists of two folds called the Labia Majora . The Labia Minora are the two folds located just inside the Labia Majora. Clitoris This organ is responsible for stimulating female orgasm. The clitoris is the sensory and erectile organ of the female(sensory organ analogous to the male's penis). It is located just inside the vulva. Stimulation of the clitoris causes contractions that move semen into the female reproductive tract. Vagina The vagina serves as the female organ of copulation (receptacle for the...
