Influence du taux de phosphore alimentaire sur les performances de lapines reproductrices

Abstract 

A total of 240 rabbit does of the A 1077 strain, were divided into 4 equivalent groups. From 3 days before the first parturition, they received ad libitum, one of the 4 diets containing 1.2% of calcium, 0.45% - 0.55% - 0.66% or 0.76% of total phosphorus. Reproductive and fattening performances were controlled for 6 months: remating 10 days post partum, weaning at 30days and slaughter at 2.3 kg. The doe's reproduction performances were not affected by phosphorus level: 8.69 - 8. 83 - 8.31 and 8.58 young born alive per litter, 5.39 - 5.90 5.59 and 6.13 weaned for the 4 diets in the same order. The interval between 2 kindlings was the same for the 4 groups : 48 to 50 days. In other hand, the young's weaning weight was reduced by 7% with the 0.76% phosphorus diet. But the fattening growth rate (34.8 - 35.1 g/d) and mortality until slaughter weight (5.1% - 6.9%) were independent of mother's diet, even for the highest level of phosphorus .
