NOTE

LIVESTOCK RATIONS

Differences between the types of rations

  1. Balanced Ration: This ration is formulated to meet the overall nutritional needs of the animal, including maintenance, growth, reproduction, and other physiological functions. It contains a proper balance of all essential nutrients in the correct proportions to ensure optimal health and performance.
  2. Maintenance Ration: The primary goal of a maintenance ration is to sustain the animal's body weight and condition without promoting growth or additional production. It provides the necessary nutrients to support basic metabolic functions and sustain the animal's current state without excess energy or protein.
  3. Production Ration: Unlike maintenance ration, a production ration is specifically formulated to support increased production levels, such as milk production in dairy cows, egg production in poultry, or weight gain in meat animals. It contains higher levels of energy, protein, and other nutrients to meet the increased demands of production while maintaining overall health.

Nutrients Constituting Various Rations

The following are different nutrients that constitute the types of rations of livestock:

  1. Balanced Ration:

   - Energy sources (carbohydrates, fats)

   - Protein sources (amino acids)

   - Vitamins (A, D, E, K, B vitamins)

   - Minerals (calcium, phosphorus, potassium, magnesium, etc.)

   - Fiber sources (roughage)

   - Water

  1. Maintenance Ration:

   - Energy sources (carbohydrates, fats)

   - Protein sources (amino acids)

   - Vitamins (A, D, E, K, B vitamins)

   - Minerals (calcium, phosphorus, potassium, magnesium, etc.)

   - Fiber sources (roughage)

   - Water

  1. Production Ration:

   - Higher levels of energy sources (carbohydrates, fats)

   - Increased protein sources (amino acids)

   - Specific vitamins and minerals tailored for production (e.g., increased calcium for eggshell formation)

   - Fiber sources (roughage)

   - Water
