Document Summary
Role in mother nature: propagation and survival of a species, many times if the environmental conditions aren"t suited to support babies, animals will not have them. Role in agriculture: efficiency of reproduction is an important key in the animal production industry, maximizing fertility is a key goal of any livestock producer. Without fertility, there would be no babies and therefore no profit. How important is reproduction: a high reproductive efficiency relates to increased profitability. Puberty: the transitional state through which animals progress from an immature reproductive and hormonal state to a mature state. Nutrition (weight: heavier animals tend to hit puberty faster because the body believes that because the animal is heavier it must be older instead of just fat. Health: secondary sex characteristics develop because of puberty. Examples) lower voice, more muscling, burly hair, etc. The period of sexual receptivity: follicle stimulation/rupturing and ovulation.
