Cow’s milk on a dairy farm

Cow’s milk is produced for delivery to milk processing industry

Sales of cow’s milk = basic income for dairy farm

Cow’s milk of first 2-3 days after calving is undeliverable

Milk of cows treated with antibiotics is undeliverable

Undeliverable milk = rest milk

Farmers prefer not to dump rest milk

Feeding cow’s milk to calves seems easy and cheap

Advantages of cow’s milk

Cow’s milk tastes good, is well-accepted by calves high intake of cow’s milk slows down intake of concentrates

Cow’s milk is easy to supply correct execution means more manual work

Calves on cow’s milk look good Only optical:because of shine (high fat) and filling (rennet)

Dumping rest milk is financial loss is correct, but can be approached differently: Better management of rest milk (later)

Disadvantages of cow’s milk

Cow’s milk may contain harmful pathogens Transmission of Para-tbc on other threats

Penicillin milk contains antibiotics Create resistance of dairy cows against penicillin

Cow’s milk is too fat slows down rumen development, insufficient growth after weaning

Cow’s milk is low in vitamins and trace elements More anemia and weaker bone structure

Page 7: Sprayfo and cow’s milk. Content Feeding cow’s milk to rearing calves Cow’s milk Calf Milk Replacer Management of rest milk Cow’s milk on dairy farm

Creative with cow’s milk?

Too much fat dilute milk with waterconsequence: less vitamins and trace elements

Too much fat skim the cream off the whole milkconsequence: less fat-soluble vitamins

Labour involved = too much manual work on large farms

Simple calculation:For feeding 50 calves = transport 15,000 litres of cow milk = poor 80 bags of calf milk replacer in

an automatic drinking machine

Calves on cow’s milk low in iron

182 bull calves to trial farm Sloten in 2009

Age at arrival: over 2 weeks

At arrival all calves tested on Hb value (standard)

Bull calves most fed with cow’s milk

Minimum – reference Hb value is 10.5 mg / 100 ml

Average Hb value is 8.8 TOO LOW !

• 20% meets standard > 10.5

• 46% too low 8 – 10.5

• 34% critically low < 8

Watch out with feeding too much milk

Milk only Low concentrate intake Bad rumen development

Conclusion:

In theory, a farmer

does not have a surplus

of rest milk

Number of dairy cows 100 head

Milkproduction first 2 days 40 liter

Penicillin milk (Days/year) 0 days

Avarage daily milkproduktion 30 liter

Amount of rest milk per year 4000 liter

Female calves for rearing 40%

Female calves for sales 10%

Male calves for sales 50%

Colostrum supply first 3 days 12 liter

Whole milk feeding first 2 weeks 60 liter

Feeding rearing calves first 3 days 480 liter

Feeding male calves first 2 weeks 3000 liter

Farmer with

too much rest milk

has a different challenge

Conclusions

Page 19: Sprayfo and cow’s milk. Content Feeding cow’s milk to rearing calves Cow’s milk Calf Milk Replacer Management of rest milk Cow’s milk on dairy farm

Sprayfo made for calf rearing

Feed calves with: Cow’s milk Sprayfo

Prevents transmission of diseases No Yes

Stimulates intake of concentrates Low High

Level of vitamins & trace elements Too low Perfect!

Nutrient composition Variable Very constant

Effect on farm profit

(with feeding rearing calves)Moderate Good

Page 20: Sprayfo and cow’s milk. Content Feeding cow’s milk to rearing calves Cow’s milk Calf Milk Replacer Management of rest milk Cow’s milk on dairy farm

Sprayfo better for calf rearing

Safer• constant composition, less chance of diarrhoea• with Safety Packege and/or specific antibodies

Healthier• added iron and vitamins• composition enhances intake concentrates• less transmission of diseases (such as Para-tbc)

Simpler• to feed calves irrespective of milking time• especially in case of automatic feeding• less diarrhoea problems

AND a higher profit per dairy cow!

Page 21: Sprayfo and cow’s milk. Content Feeding cow’s milk to rearing calves Cow’s milk Calf Milk Replacer Management of rest milk Cow’s milk on dairy farm

Sprayfo brings higher profit

Cost price per litre Sprayfo is lower than 20 cents

Sales price per litre cow’s milk is more than 25 cents

In short:

Sell cow’s milk for highest profit

Including package of advantages: growth, health, durability and milk production in future
