Prologue

• In summer 2017 several applications for funding of projects concerning calves were submitted to the Danish Cattle Levy Fund (KAF)

• The KAF board decided that there was a need for coordinated action and asked for an integrated approach

• An interdisciplinary R&D project for 2018-2021 was submitted by 4 partners:

• SEGES (project leader)

• Copenhagen University

• DTU Veterinary Institute

• Aarhus University

Objective

To enhance production of healthy and robust calves by means of knowledge and tools to improve calf health and performance through better management.

This will be achieved through

• Systematic collection of knowledge and data from clusters of dairy and veal farms

• Development of diagnostic tools for monitoring of calf health and immune status

• Test of alternatives to antibiotic treatment (probiotics, NSAID‟s, antibiotic-free production)

• Development and implementation of IT management tools

WP 1 – What we didn’t know about calves

Why do we want to carry out the activities in WP 1?

• In contrast to adult cows, there is a lack of systematic information and data on calf production (health, housing, feeding, management etc.)

• If you don‟t have the basic information it is difficult to know what to improve

• If you don‟t have the proper tools it is difficult to measure the effect of the improvements

• There is a straight connection between dairy herds and veal producers – this should be exploited a lot more



AP3. ALTERNATIVES TO ANTIBIOTICS A. Pain relief treatment as an alternative

WP 2 – What is a healthy calf?

Why do we want to perform the activities in WP 2?

• The veal producer (and the dairy farmer!) needs to know if the calf entering his farm has a ”sufficient” immune status – we need a tool to measure this

• Disease patterns are quite herd specific – can objective and tailor-made disease monitoring / diagnostics be useful in disease prevention and control?

WP 3 – Do we need to use antibiotics?

Why do we want to carry out the activities in WP 3?

• The cattle industry is committed to a reduction of antibiotic use in calves – which means there is a need for alternatives (prevention and/or treatment)

• Do sick animals always require antibiotics – or is pain relief and anti-inflammatory treatment in many cases sufficient?

• Prevention is better than cure – can probiotics be useful?

• And will it, in the end, be possible to produce veal calves without the use of any antibiotics?

WP 4 – Making the right decisions

Why do we need yet another management system?

• We need to improve the farmer‟s decision making possibilities

• We need to define ”robustness” and how to measure it

• We need an IT based tool that enables the farmer to register data, set goals for his production, and evaluate if he is making progress

Take home message

• The ”Robust calves” project will deliver new knowledge and tools to improve health and performance in dairy and veal calves

• Ambitious? Yes.

• Exciting? Definitely!

• See you in 4 years
