Sheep NutritionAg Production III

Mr. DeBord

Nutrition The largest single production cost in any

livestock operation is feed. Due to the unique nature of the sheep’s gastrointestinal tract. Forages can comprise the majority of a ewes diet. Sheep diets must be designed to support optimal production, while also being economical. Nutritionally sound diets will avert nutrition related disorders, thus promoting heatlh and productivity

Nutrient Requirements are influenced by:

Age Stage of production Forage quality and quanatity Production system (range versus

confinement) Environmental/climatic conditions Management Body Condition

Nutrient needs Water Energy Protein Minerals Vitamins

Water The need for water is basic.

Unlimited fresh water supply is needed for sheep in all stages of production. Limitations to water intake may limit feed intake.

Energy Insufficient energy limits ewe

performance more than any other nutrient.

The predominate energy source for ewe diets in forage.

For feedlot lambs, grain sources are used to supply most energy needs

Protein The need for supplemental protein

depends on production stage and quality of available forages.

Protein supplementation of sheep can increase rumen microbe activity, which will increase forage intake, digestion, and performance

Young growing lambs and high producing ewes require higher levels of amino acids.

Minerals The relationship of minerals to each

other must be taken into account when formulating supplemental sheep mineral. The amount of one mineral may influence the amount of another mineral needed in the diet.

Lack of a mineral creates a deficiency Too much mineral creates a toxicity Sheep are sensitive to copper

Vitamins Sheep require dietary sources of

vitamins A,D, and E Lambs also require K and B vitamins
