SPRING BREEDER GAIN Spring Breeder is a specialised fertility feed for grazing cows before and during the breeding season.

Features and Benefits

Main Ingredients

• Digestible fibre blend of Citrus pulp/Beet pulp/Soya hulls helps stabilise rumen pH and prevent Acidosis.

Barley, Maize, Citrus pulp, Sugar Beet pulp, Soya hulls.

• Maize rumen by-pass starch fuels milk protein production, without creating excess rumen acid.

Feed Guidelines

• 13% Protein, slow-release energy formulation promotes high grass intake and milk solids output.

• Native cereals provide rumen energy to improve nitrogen utilization.

Feed to milking cows as a supplement to grazed grass.

Feed 2.5kg/cow/day to provide 60g Cal Mag (30g Magnesium) to help prevent Grass Tetany.

Do not exceed 4kg, to avoid overfeeding minerals.

• NOVATAN® Protein Protector improves N utilisation, boosts PDIE protein supply, reduces rumen ammonia and pasture scouring, and supports milk solids and fertility.

Do not provide other additional minerals without professional advice.

• Protected minerals improve availability for fertility support on a rapid-throughput pasture diet. - Bioplex® Copper and Manganese support fertility. - Bioplex® Zinc helps support udder and hoof health. - Sel-Plex® Selenium supports immunity, SCC and fertility. • Full mineral allowance (Calcium, Phosphorous, Magnesium, Sodium) in 2.5kg daily feed rate. • Full trace element allowance (Copper, Selenium, Iodine, Zinc, Manganese, Cobalt) in 2.5kg daily feed rate. • Magnesium (Cal Mag 60g/2.5kg) helps prevent Grass Tetany.

NUTRIENT

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.
