GAIN Spring Starter

SPRING STARTER GAIN Spring Starter is a premium early-lactation feed for cows before and after Spring turnout. Main Ingredients Barley, Citrus pulp, Maize, Soya hulls, Corn Distillers Grains.

Feed Guidelines • Feed to milking cows as a supplement to grass silage or grazed grass. • Feed 4kg/cow/day to provide 60g Cal Mag (30g Magnesium) to help prevent Grass Tetany.

Features and Benefits • 16% Protein suits cows on grass silage or pasture. • Balanced energy profile (digestible fibre/quick starch/ by-pass starch) suits transition from silage to grass. - Digestible fibre blend of Citrus Pulp and Soya hulls supports milk yield by reducing rumen acid load. - Native cereals provide readily available “quick” starch to fuel rumen fermentation. - Maize rumen by-pass starch fuels milk protein production, without creating excess rumen acid. • AGOLIN® rumen modifier improves feed utilisation by improving energy and protein utilisation in the rumen.

• Do not exceed 6.0kg, to avoid overfeeding minerals.

- AGOLIN® reduces feed energy loss by reducing Methane Greenhouse Gas emissions.

• Do not provide other additional minerals without professional advice.

- AGOLIN® reduces rumen ammonia and milk urea nitrogen, and improves manure consistency. • Full mineral allowance (Calcium, Phosphorous, Magnesium, Sodium) in 4kg daily feed rate. • Full trace element allowance (Copper, Selenium, Iodine, Zinc, Manganese, Cobalt) in 4kg daily feed rate. • Magnesium (Cal Mag 60g/4kg) helps prevent Grass Tetany.

A cow will reach her highest daily milk output 6–8 weeks after calving but will only reach her highest intake of dry matter 10–12 weeks post-calving. In the meantime, the cow will use energy from her fat reserves to make up the deficit for several weeks. If this period is not controlled, and the cow loses too much body condition in early lactation, fertility will be significantly compromised.

Milk Fat is the biggest driver of UFL requirement/litre

Intake will increase by 0.75–1.0kg DM every week until reaching peak intake at 16–18kg DM during week 10–12 of the lactation.

Where the cows dietary requirements are not met and excessive BCS losses are experienced post-calving, detrimental effects on conception rates will be the subsequent result. See below the extent of effects on conception rates when differing alterations in BCS are experienced post-calving.
