Importance, Composition and Utilization of Sheep and Goat Milk

(As per ICAR Recommended Textbooks)

Introduction

Sheep and goats are known as “poor man’s cow” due to their low maintenance cost and ability to produce milk under diverse agro-climatic conditions. According to ICAR-recommended livestock production literature, sheep and goat milk has high nutritive value, better digestibility, and special therapeutic importance. Although their milk yield is lower compared to cattle and buffalo, the quality of milk—especially in terms of fat, protein, and total solids—is superior. Therefore, sheep and goat milk plays an important role in human nutrition, rural livelihood, and value-added dairy product preparation.

Importance of Sheep and Goat Milk

(ICAR Point of View)

  1. High Nutritive Value

    • Rich in fat, protein, calcium, phosphorus, and vitamins

    • Provides essential amino acids for growth and development

  2. Better Digestibility

    • Smaller fat globules than cow milk

    • Soft curd formation in stomach

    • Easily digestible for infants, elderly, and sick persons

  3. Medicinal and Therapeutic Importance

    • Goat milk is recommended for people allergic to cow milk

    • Beneficial in anemia, malabsorption syndrome, and digestive disorders

  4. Economic Importance

    • Source of regular income for small and marginal farmers

    • Suitable for landless laborers and women farmers

  5. Adaptability and Sustainability

    • Animals thrive in arid, semi-arid, and hilly regions

    • Require less feed and water compared to large dairy animals

Composition of Sheep and Goat Milk

(Average values as given in ICAR textbooks)

1. Composition of Sheep Milk

Component                       Percentage
Water80–82%
Fat6.0–8.0%
Protein5.0–6.0%
Lactose4.5–5.0%
Minerals (Ash)0.9–1.0%

🔹 Sheep milk contains very high total solids, making it highly suitable for cheese and butter production.

2. Composition of Goat Milk

Component                      Percentage
Water86–88%
Fat3.5–4.5%
Protein3.0–3.5%
Lactose4.0–4.5%
Minerals (Ash)0.7–0.8%

🔹 Goat milk closely resembles human milk in composition and digestibility.

Special Characteristics (ICAR Notes)

  • Smaller fat globules

  • Higher buffering capacity

  • Higher calcium and phosphorus content

  • Lower α-s1 casein in goat milk (less allergenic)

Utilization of Sheep and Goat Milk

1. Direct Consumption

  • Consumed fresh or boiled

  • Used as nutritive food for children and patients

2. Preparation of Dairy Products

From Sheep Milk:

  • Cheese (e.g., Roquefort, Pecorino)

  • Butter

  • Ghee

  • Yogurt

From Goat Milk:

  • Goat cheese (Chevre)

  • Paneer

  • Curd and yogurt

  • Milk powder and flavored milk

3. Infant and Clinical Nutrition

  • Used in specialized infant food formulations

  • Recommended in case of cow milk allergy (as per medical advice)

4. Cosmetic and Pharmaceutical Uses

  • Used in preparation of soaps, creams, and lotions

  • Beneficial for skin health due to natural fats and proteins

5. Rural Dairy Development

  • Promotes small-scale dairy enterprises

  • Generates employment in rural areas

Comparative Advantage over Cow Milk

(ICAR Exam-Relevant)

Limitations (ICAR Notes)

  • Low milk yield per animal

  • Seasonal production

  • Limited organized marketing system in India

Conclusion

According to ICAR-recommended livestock production literature, sheep and goat milk is nutritionally superior and has better digestibility compared to cow milk. Sheep milk is rich in fat and protein, making it highly suitable for manufacturing value-added dairy products, while goat milk is easily digestible and has important therapeutic value. Proper utilization and processing of sheep and goat milk can enhance income of small farmers, improve nutritional security, and support sustainable livestock development. Therefore, promotion of sheep and goat milk production deserves greater attention in Indian dairy farming.
