Which of the following type of rations will supplies the animal with just the quantity of nutrients that are enough to enable the animal carry on with vital body activities without losing or gaining another substance

Awọn alaye Idahun

The type of ration that supplies the animal with just the quantity of nutrients that are enough to enable the animal to carry on with vital body activities without losing or gaining another substance is called the "maintenance ration." A production ration is designed to provide nutrients for specific animal production goals, such as milk production or weight gain. A balanced ration is formulated to provide all the necessary nutrients in appropriate amounts to meet the animal's needs. A measured ration is a ration in which feed ingredients are weighed or measured out in specific amounts to meet the animal's nutrient requirements.

One of the followings is not a basic consideration in planting operations

Awọn alaye Idahun

Planting weed is not a basic consideration in planting operations. The other options listed are all important factors to consider when planting, as they can affect the growth and development of the plants. Planting space determines how far apart to plant the seeds or seedlings, which affects how much space the plants will have to grow and how much light, water, and nutrients they will receive. Planting time is important because different plants have different requirements for temperature and moisture, and planting at the wrong time can result in poor growth or even the death of the plants. Planting depth is important because different seeds require different depths to germinate properly, and planting too shallow or too deep can affect the germination rate and the growth of the plants.

Which of the following processes is not used in rice processing

Awọn alaye Idahun

The process that is not used in rice processing is fermentation. Threshing is the process of separating the grain from the straw, while winnowing is the process of separating the chaff from the grain. Perboiling involves partially boiling the rice in the husk, which results in increased nutritional value and easier removal of the husk. Fermentation is a process used in the production of certain types of alcoholic beverages and some food products, but it is not a typical step in rice processing.

This is the removal of unwanted plants on the farm

Awọn alaye Idahun

The correct answer is: Weeding. "Weeding" refers to the process of removing unwanted plants from a farm or garden to help the desired plants grow better. "Thinning" usually refers to the removal of excess plants to allow the remaining plants to grow stronger and healthier. "Mulching" refers to the practice of covering the soil with a layer of material (such as leaves, straw, or bark) to retain moisture, suppress weed growth, and improve soil quality. "Supplying" does not relate to the removal of unwanted plants on a farm. It could refer to the act of providing necessary resources, such as water or nutrients, to the desired plants.
