Answer:
The effects of environment on reproduction
According to Jöchle and Lammond (1980) environment factors which influence or interfere with reproduction are consisting of inanimate and animate factors as listed below:
A. Inanimate factors:
1. Biometereological factors:
a. Climate and seasonal changes in photoperiod, temperature, humidity and precipitation;
b. Significant short-term changes in climate = weather;
c. Microclimate imposed by man.
2. Nutrition
B. Animate factors:
1. Other forms of life interacting in an undesirable or fatal manner; infections, endoparasites, ectoparasites;
2. Interaction with members of the same species: social factors;
3. Interaction with the man.
C. These and other factors affecting the “milieu intern”, the homeostatic capability of the
organism having repercussions on the reproductive function.
In order to consider the effect of environment factors on techniques which may be imposed on animals to control reproduction, it is appropriate to divide these factors in classes:
a. external factors acting through stereoceptive pathways which modify hypothalamicpituitary functions (photoperiod, temperature, odors, sight and noise);
b. factors which may act on the organism as a whole (nutrition, diseases, changes in
climate, seasons and weather);
c. combinations of the above, plus social factors and encounters with man and his actions, and how they interact with the body’s homeostatic capabilities, effecting reproduction
Answer:
It has been long recognized that the environment has an important role to play in the regulation of the mammalian reproductive function. Environmental cues, such as changing day-light or increase temperature, are know to trigger off growth or regression of the reproductive organs in a whole variety of species and nutrition and stress can inf luence the onset of breeding and affect the fertility
