Effect of dietary supplementation with coco-nut babaçu oil on performance of lactating mares

Abstract

Mares have the highest nutrient requirement in the first three months of lactation. Energy is important for mares to maintain body condition and produce milk for their foals. The effect on body weight changes were investigated through supplemental coconut oil (CO) at four levels (0, 4, 8 and 16%) in concentrate fed to 16 multiparous mares in early lactation with average body weight 441.2 Kg. Mares were fed 1,5% live weight with concentrate composed of corn meal, wheat bran and soybean meal with 16% crude protein. The forage was Napier grass, mineral supplement and water "ad libitum". Mares were allotted to 16 pens (4x5m) and randomly assigned to receive four diets once a day during 42 days. At the end of the experiment the CO supplementation did not affect mares body condition The results indicated that in tropical conditions level at 4% CO supplementation had better results for lactating mares.
