(Reprinted from Pygmy Goat WORLD magazine with permission) Sterility in the buck is usually the exception rather than the norm and is usually temporary. Male fertility is affected by such things as age, maturity, nutritional status, general health, endocrine balance and normality of sex organs. Sperm quality , nutrition, body weight, maturity, stress, disease, mating frequency, seasonal and climatic changes, and management also play roles in male fertility.
The temperature at the surface of the Sun is about 10,000 Fahrenheit (5,600 Celsius). The temperature rises from the surface of the Sun inward towards the very hot center of the Sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius).
Surface temperature. Also, if a star has the same radius as the sun but a higher surface temperature, the hotter star exceeds the sun in luminosity. The sunâs surface temperature is somewhere around 5800 Kelvin (9980 o Fahrenheit).Thatâs 5800 degrees above absolute zero, the coldest temperature possible anywhere in the universe.etâs presume a star has the same surface temperature as the sun, but sports a larger radius. In that scenario, the star with the larger radius claims the greater luminosity. In the example below, weâll say the starâs radius is 4 solar (4 times the sunâs radius) but has the same surface temperature as our sun.
