ABSTRACT Was evaluated the pattern of growth among females and males of tambaqui by Gompertz nonlinear regression model. Five traits of economic importance were measured on 145 animals during the three years, totaling 981 morphometric data analyzed. Different curves were adjusted between males and females for body weight, height and head length and only one curve was adjusted to the width and body length. The asymptotic weight (a) and relative growth rate to maturity (k) were different between sexes in animals with ± 5 kg; slaughter weight practiced by a specific niche market, very profitable. However, there was no difference between males and females up to ± 2 kg; slaughter weight established to supply the bigger consumer market. Females showed weight... |

ABSTRACT The objective of this study was to evaluate the effect of source of roughage and crude protein level on feeding performance and carcass traits of Majaheem camels (Camelus dromedarius). Forty-eight male calf-camels weighing 203.3±5.1 kg were equally assigned to a 2 × 3 factorial arrangement of two sources of roughage (Rhodes grass hay and dry salicornia biomass) and three dietary crude protein levels (12, 14.5, and 17%); the feeding trial lasted for 18 weeks. The results showed that slaughter and hot carcass weights, average daily gain, dry matter intake, feed efficiency, and separable fat from 9th-11th rib joint increased as the crude protein in the diets increased from 12 to 14.5%, whereas increasing crude protein to 17% resulted in no further... |
