The two players and their research topics

International Beef Cattle Workers Group 2


Beef researches in Inra Clermont-Ferrand

Mains objectives :• Adaptative capacities of beef cows• Optimisation of beef production efficiency and

meat quality• Technical and economic performances of

commercial beef farms in grassland areas

Facilities :• 200 suckler cows (Charolaise, Salers)• 120 fattening young cattle (bull, steer, females)• Slaughter house

Milk and concentrate intakes in Salers calves modify body composition at weaning and

next feeding efficiency during finishing

1. How ratios milk/forage/concentrate beforebefore weaning modify:growth

body and carcass compositionfeeding efficiency

2. and what are the residual impacts during fattening?

Salers cow / Milk production

Fattening

16-17 months

4.5 to 6.5 kg Concentrate/animal/d Hay of permanent grassland ad libitum

additional suckling /dairy cow = 900 kg more milk drunk at weaning

Calves can drink more milk, only dams milk production is limiting

With 2000 kg of milk ingested, calves had an ADG of 1500 g/d before weaning without concentrate supplementation.

A diet before weaning favoring milk and forage compared with concentrate provided comparable carcasses.

Animals supplemented with milk deposited more protein than animals supplemented with concentrate.

Gross margin per animal of Concentrate group was lower than Milk (-100 €) and Control (-85 €) groups.

Conclusions

Higher feeding efficiency in the milk group with a residual effect during early fattening.
