SUMMARY The study aimed to evaluate the effect of feed restriction on the development of organs and fat deposition in castrated Caninde goats. Twenty one goats were distributed in a completely randomized design, with initial body weight of 15.9 ± 1.03kg. The goats were allocated into three levels of feed restriction (seven animals per level): ad libitum; moderate restriction (restriction of 20% on the amount of feed consumed by the animals fed ad libitum) and severe restriction (40% restriction on the amount of feed consumed by the animals fed ad libitum). The diet consisted of 55% forage (Tifton) and 45% concentrate. At 110 days of experiment, the goats were slaughtered with abody weight of 23.5kg ± 2.5kg. The components included the internal organs (spleen, heart, liver, pancreas, lungs, kidneys, blood) the emptied and cleaned digestive tract and fat deposits (in heart, mesenteric, omental and pelvic-renal) were weighed. Feed restriction in Canindé goats affected the weight of organs and fat deposition in regions more involved with the energy storage function (mesenteric, omental and pelvic-renal) (P < 0.05), however, feed restriction does not affect the percentage of the organs in relation to EBW (P > 0.05), indicating that even under feed restriction organ development is proportional to the development of the body.
