• Management

Think before purchasing a milk cup system

• It is expensive – be aware of the costs

Sows with milk cups can take care of many pigs

Medd. 1116

81 % of the sows with fewer than 16 pigs,

weaned more than 14 pigs.

Without milk cups

Nursing capacity among Danish sows in the period 2016 to 2017 in two test herds

(Bruun et al, 2017 and Sørensen and Krogsdahl, 2017)

With milk cups:

• 14 pigs 58 %

• 15 pigs 30 %

Why is it not easy!

• Pigs over 1 kg at birth: 80 % of the pigs use the cup (Report no. 1111)

• Pigs over 700 g at birth: 50 % of the pigs use the cup (Aarhus University)

• The smallest pigs do not use the cup

• The cup is a “safety net” under sows with poor nursing capacity, but only saves the pigs that want to drink

Is it because of the pig, the cup

or the milk – we do not know!

The pigs do not use the cup automatically

How to increase ”egen-fravænning”

• The pigs must use the cup

• The cup must be clean

• The system must be clean so that the milk does not taste bad

• The pig must be able to digest the milk

• Learn to take care of sows with many pigs

Behaviour

Pigs drink

Do you want to be one of those with top results

System

• Use acid and base (use only approved biocides when the pigs are in the pen)

• Use the system's automatic procedures and afterwards check yourself

Cup

• Clean daily

Wet feed trough

• Also need to be cleaned

• Do not use air

Good milk

Milk replacer contain:

• Dairy products

• Vegetable fat

• Vegetable protein

Extra delicious content:

• Blood plasma, colostrum, probiotics.

We do not know how much is

needed!

Must contain MILK!

• The young pig can only digest milk

• The challenge - The ingredients are by-products that do not have the ideal nutrient composition for a piglet.

• Skimmed milk powder

• Whey powder

• Baby food

• Etc.

The way to high ”egen-fravænning”

• Your sows have high nursing capacity and litter growth

• The pigs drink delicious milk from a clean cup

• You have good management and high survival rate among the pigs

• Increase gradually with one pig at a time

• You are still making ”mindsteammer”

• Accept ”opsamlingssøer”

• Do not move the smallest pig - move the one to be moved

Problems

1. Challenges with capacity in the farrowing house

2. High piglet mortality

3. The system must take care of pigs

1. Higher ”egen-fravænning”

2. Higher weaning weight

3. More robust pigs at weaning

Benefits

• A milk cup system can reduce the use of nursing sows

• Low mortality requires good management – it comes before a system

• The milk system does not take care of the pigs for you!

• Sows with a milk cup can take care of more pigs!

• The pig must be able to digest the milk and high litter size reduces the weight of the pig

• The pig is getting heavier, but it is more robust?

It is expensive! 17..

• A milk cup system costs DKK 12.50 per weaned pig

• DKK 10 goes to milk

The cost is DKK 12.50

↑ 650 g increased weaning weight

↓ 2.5 percentage point mortality

2016 prices - Erfa. 1708

• A milk cup system is not always the cheapest solution when you have capacity problems

• Calculate whether or not you should build farrowing pens or reduce the sow number

The benefits must always be calculated at herd level! 18..

• The benefits is depending on the opportunities in each

herd

Keep an eye on operating costs

• Record the consumption of the milk powder every month

• Calculate kg and price per weaned pig

• Compare with other herds

• Consumption tells about hygiene, milk, residues etc.
