Analyse du coût de renouvellement en élevage bovin lait : Analyse du renouvellement et de la carrière des vaches laitières, coût de production des génisses et identification de marges de progrès

Abstract : In dairy farming, the breeding of heifers guarantees the long-term survival of the farm. In the absence of a dynamic market, by habit or by will, most breeders raise all their heifers and prematurely reform their dairy cows, which are often still good producers. It was proposed by the Chambre d’Agriculture du Nord-Pas-de-Calais to focus on the herd replacement cost by adding value to datas from technical and economical management in 2018. A study conducted on 141 farms, specialized in milk production, gives us some interesting leads. The average herd replacement rate is 35%. The herd replacement cost is the difference between the product of the reforms of the females and the cost of raising heifers to replace them. It is on average 34 €/1000L but the variability between the farms is noticeable. The cost of raising heifers is on average 1430 €. Among the expenses related to the breeding of heifers, the food cost is the most variable cost and is estimated on average at 700€/heifer. In order to properly analyze the replacement cost, the context of the operation must be taken into account. Breeding farms with high replacement costs are generally increasing livestock. To control replacement costs, it is recommended to sell the surplus of the replacement with heavy-in heifers or to use cross calving. Lowering the age at first calving and increasing the longevity of cows can reduce the cost of replacement.
