Effects of mode of supplementation upon milk and growth performances of suckling Creole goats and their kids reared at pasture in Guadeloupe

Abstract : Three consecutive experiments were carried out to determine the effect of supplementation upon milk production and growth performance of Creole goats in Guadeloupe. Creole goats and their kids were reared on a Digitaria decumbens pasture. Each year, three cohorts of goats were conducted: in the dry season (D season), in the rainy season (R season) and in the intermediate season (I season). Weaning took place at 81.7 ± 5.9 days post-partum. In a first trial during R and D seasons, does were offered either 0.45 kg/day (GS group) of commercial pellets (10.3 MJ ME and 180 g CP per kg DM) or no supplements (GN group). In a second trial in D, R and I seasons the same total amount of 35 kg pellets per goat and per lactation were distributed either regularly (RD group, as above for GS group) or either gradually (GD group). In the third trial in D, R and I seasons, feeding of the does was the same as for GD group in trial 2. Treatments were determined according to the supplementation level of the kids: in KS, commercial pellets were supplied ad libitum from the 6th week to weaning and in KN there was no supplementation. In trial 1, supplementation of the does increased milk production (1023 vs 520 g/d), average daily gain of the kids and reduced the mortality rate. In trial 2, the mode of supplement distribution had no effect upon milk production and growth rate of the kids. In trial 3, the adjusted mean daily milk production for the first 6 weeks of lactation was 1218 g/d. Supplementary feeding of the kids increased growth rate from 40 days to 80 days, weaning weight and live weight at 120 days. Further studies are required to set up supplementation strategies according to the whole system of production, over the production cycle of the doe and the kid, and in different seasons, in accordance with availability of tropical feeds.
