NOTE

MALNUTRITION IN LIVESTOCK PRODUCTION

Malnutrition refers to a condition where there is an imbalance between the intake of nutrients and the body's requirements, leading to deficiencies, excesses, or imbalances in essential nutrients. It can encompass both undernutrition (insufficient intake of nutrients) and overnutrition (excessive intake of nutrients).

Symptoms of malnutrition

   - Weight loss or failure to gain weight

   - Muscle weakness and wasting

   - Fatigue and weakness

   - Delayed wound healing

   - Impaired immune function, leading to increased susceptibility to infections

   - Edema (swelling) due to fluid imbalance

   - Brittle hair and nails

   - Skin problems, such as dryness, scaling, or dermatitis

   - Developmental delays in children

Causes of malnutrition

  1. Inadequate dietary intake: Poor access to food, lack of variety in diet, and insufficient consumption of essential nutrients.
  2. Poor absorption: Digestive disorders, such as celiac disease or Crohn's disease, can impair nutrient absorption.
  3. Increased nutrient requirements: Conditions like pregnancy, lactation, illness, or injury increase the body's need for certain nutrients.
  4. Food insecurity: Limited access to nutritious food due to poverty, conflict, or environmental factors.
  5. Socioeconomic factors: Lack of education, poor sanitation, and limited access to healthcare can contribute to malnutrition.
  6. Cultural and dietary practices: Cultural beliefs and dietary habits may lead to inadequate nutrient intake or imbalances in the diet.

Effects of malnutrition on livestock production

  1. Reduced growth rates: Malnourished animals may fail to reach their full growth potential, leading to decreased productivity.
  2. Poor reproductive performance: Malnutrition can impair fertility, decrease conception rates, and increase the incidence of reproductive disorders.
  3. Decreased milk production: In dairy animals, inadequate nutrition can lead to reduced milk yield and quality.
  4. Increased susceptibility to diseases: Malnourished animals have weakened immune systems, making them more susceptible to infections and diseases.
  5. Poor carcass quality: Malnutrition can affect meat quality, leading to reduced market value of livestock products.
  6. Increased mortality rates: Severe malnutrition can lead to increased mortality rates among livestock due to weakened health and susceptibility to diseases.

EVALUATION: 1. What is malnutrition

  1. Identify 5 symptoms of malnutrition
  2. Identify 5 causes of maltreatment to livestock production
  3. Mention 5 effects of maltreatment

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
