Question

Корова съедает в сутки около 70 кг. травы. Пастбищный сезон длится в среднем 150 суток. Примерная урожайность пастбищных культур 250 ц/га. Какова площадь пастбища, необходимого одной корове на пастбищный сезон?

Answer 1

1) 70х150=10500 (кг )
2) 10500:25000=0,42 (га )

Answer 2

Calculation of Pasture Area for One Cow

To calculate the pasture area required for one cow during the grazing season, we need to consider the amount of grass consumed by a cow per day, the duration of the grazing season, and the approximate yield of pasture crops.

According to the information provided, a cow consumes approximately 70 kg of grass per day and the grazing season lasts for about 150 days. The approximate yield of pasture crops is 250 kg per hectare (or 250 centners per hectare).

To calculate the pasture area required for one cow, we can use the following formula:

Pasture Area = (Grass Consumption per Day) x (Grazing Season Duration) / (Yield of Pasture Crops)

Substituting the given values into the formula:

Pasture Area = (70 kg/day) x (150 days) / (250 kg/ha)

Simplifying the calculation:

Pasture Area = 10500 kg / 250 kg/ha

Pasture Area = 42 hectares

Therefore, approximately 42 hectares of pasture area would be required for one cow during the grazing season.

Please note that this calculation is an approximation and may vary depending on factors such as the nutritional value of the grass, the size and breed of the cow, and the specific conditions of the pasture.
