Which of the following classes of nutrient is used only for energy production in farm animals?

Bayanin Amsa

The nutrient class that is used only for energy production in farm animals is Carbohydrates. While all nutrient classes can be sources of energy for animals, carbohydrates are particularly important for providing energy quickly and efficiently. Proteins and minerals are primarily used for building and repairing tissues and structures in the body, while fat and oil serve a variety of functions including energy storage, insulation, and as building blocks for certain hormones.

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

Bayanin Amsa

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

Bayanin Amsa

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.

Some seeds are raised in the nursery because

Bayanin Amsa

Seeds are raised in the nursery for several reasons, including: - To protect them from harsh environmental conditions, such as extreme temperatures or heavy rain, which could damage or kill the seeds. - To provide them with a controlled environment with optimal growing conditions, such as the right amount of water, nutrients, and light. - To monitor and manage pests and diseases that could harm the seeds. - To allow for easier transplanting and handling of the seedlings once they are ready to be moved to their final growing location.
