Artificial lactation is increasing in goat farms due to its innumerable advantages. The aim of this study was to compare daily weight gain (DWG) in female kids fed with biocholine-supplemented milk or whole milk without supplementation. The study was carried out with 16 French Alpine goats separated from their mother at birth and distributed into 2 groups; the control group (CG) (n=8) from mothers fed without supplementation with biocholine and the experimental group (n=8) from mothers fed with a diet supplemented with 8 g of biocholine (BSG) (n=8). They were fed under an artificial lactation system and weighed daily until 2 months of age; the amount of milk produced by mothers was measured weekly and the percentages of protein, fat and lactose were analyzed. No statistically significant differences (P>0.05) were found for DWG, nor for any of the milk components, but statistically significant differences (P<0.05) were found for milk production. It is concluded that biocholine at a dose of 8 g increases the amount of milk, but it does not increase main milk components, so the offspring did not have higher DWG.
