  <p>The farmer facing challenges suppression of rising cost of feed due to be dependent on imported feed. The ecofeed has been a focus of attention as a solution for the challenges. The warranty of the preference and usefulness of the feed is absolutory necessary to develop the eco-feed. We took note of the aloe-vera discarded and attempted to elucidate the preference and usefulness of aloe-vera feeds for goat. Eight goats (4 males and 4 females)were assigned randomly into two groups. All two groups served to both control (commercial feed)and treatment (aloe-vera feed)according to the crossover design. In present study, the preference test and feeding experiment were carried out. We recorded the eating time, feed intake and number of animals finished eating feed given in the preference test. In the feeding experiment, the measurements of body weight, BCS and FAMACHA score, and the blood parameter analysis were performed. The eating time of animals finished eating was same as that of the good preference control feed. The body weight, BCS and FAMACHA score in the treatment were similar to those in the control, and the blood parameters for nutritional condition of animals and metabolic status of various organs was not different between the feeds. These results suggests that aloe-vera feed is palatable and useful for goat.</p>

• Effects of the castration on the growth, meat production and odors in male goats

  　View Summary

  Two experiments were conducted to clarify the effect of castration on meat quality and odor content. In experiment 1, twelve goats (crossbred of Japanese-Saanen/Nubian, 3-mo-old) were allocated into two groups (NCG: Non-castrated group, CG: Castrated group). Animals in the CG were castrated at 2.5-mo-old. Formulated feed and alfalfa hay cubes were fed twice daily (10:00 and 16:00 h). Kleingrass hay and water were fed ad libitum. Body weight was measured and body measurements were recorded monthly. At 12-month post-partum, animals were slaughtered to determine the carcass trait and loin characteristics. In experiment 2, eight goats (the above crossbred, 2-yr-old) were allocated into two groups. Animals were fed alfalfa hay cubes (10:00 h), formulated feed and Kleingrass hay (16:00 h). Water was fed ad libitum. The feed intake measurement was conducted daily. The odor intensity measurement of meat was executed. The weight of intra-abdominal fat in the CG was heavier (p<0.05) than the NCG. The concentrations of some functional compounds such as taurine in the CG were lower (p<0.05) than the NCG. The odor intensity in the CG was lower (p<0.05) than the NCG. It was elucidated that the castration of male goat resulted in lower quality of the meat and reduction of the peculiar odor.
