Sheep Nutrition
Rams, Ewes, Lambs and Show Sheep formulas
Sheep Nutrition for Every Stage of Development
Nature's Formula IGF-1 feed formulations are developed for rams, ewes, lambs and show sheep at different stages of production. Each formulation provides specific inclusion rates for starter, grower, finisher, maintenance and breeding feed programs.
With no added copper, Nature's Formula allows feed nutritionists to manage copper levels according to the nutritional requirements of sheep.
IGF-1 and Growth:
General Growth Promotion:
IGF-1 is a polypeptide hormone (anabolic steroid) derived from carotenoids in green vegetation that promotes cell growth and differentiation, impacting tissue development, including muscle and bone from conception.
Maternal Influence:
Maternal IGF-1 levels can influence the birth weight and early growth of lambs.
Muscle Development:
Numerous studies show that IGF-1 enhances muscle growth in lambs.
Dietary Influence:
Dietary interventions, such as high concentrations of vitamin A found in Natures Formula IGF-1 feed additive, combined with superior sources of protein in lamb diets, can affect IGF-1 levels and contribute to improved growth performance.
Skeletal Growth:
IGF-1 is also crucial for skeletal growth and development in lambs.
Age and Maturity:
IGF-1 concentrations tend to increase with age and body weight in lambs, which is why we decrease the levels of Nature’s Formula IGF-1 feed additive as they mature, fortifying your lambs, Overall Animal Nutrition provides you with a sliding scale of scheduled dietary platforms for the different stages of development over the course of each individual animal’s lifespan.
Research Findings
Research into IGF-1 has explored its role in growth, muscle development and reproductive function in livestock. These findings help provide context for the biological processes associated with IGF-1 and their relevance to sheep nutrition.
