Lean Start® 4 Concentrate

Lean Start®

LEAN START® 4 Concentrate is a grind and mix starter product that offers high-nutrient density, digestibility and enhanced palatability.  The superior ingredient composition and quality of this product supports high intakes along with fast and efficient growth during the starter phase. This product is designed to be mixed with corn to make a complete diet. 

About the Product

Diets made with LEAN START 4 Concentrate should be fed to pigs 40 to 70 days of age. The diet should be fed as a follow-up product to Hubbard prestarters. Age is more important than weight, but typical pig weight would be 22-60 pounds.

High Quality Lactose
Supplies high quality lactose. Lactose is a preferred energy and protein source for the young pig. The appropriate lactose levels are supplied to ease the transition to a dry diet.

Select Fish Meal
Contains the highest quality fishmeal for additional palatability. Fishmeal is highly digestible in the immature digestive tract, helping to improve gain and reduce digestive disorders.

Synthetic Amino Acids
Provides amino acid balanced nutrition while restricting exposure to soybean meal anti-nutritional factors.

Yucca Derivatives
Improves phosphorus and trace mineral digestibility, thus allowing for less total phosphorus and other trace minerals to be fed and excreted in the manure. Allows for reduced calcium for increased diet acidity.

Advanced Fat Source
Helps rapidly growing pigs get more energy from the feed.

AMINO SCIENCE® Formulation
Maintains proper amino acid ratio by formulating rations on a digestible amino acid basis. The amino acid to energy balance of the ration is optimized to obtain rapid growth and efficient feed conversion.
