Altogether 504 pheasants were selected In this expe- riment, including three stages: (I) 126 hatching pheasants (40 weeks old), the divergence of body weights being not significant (P>O.05), were divided randomly into 7 groups, with 18 pheasants (~.:65:1) in each one. Group Iwas only fed on basal diets; group 11.. III. IV were enzymeæ¢dding groups, which was respectively fed on 0.5% cel lu? lose enzyme + 0.5% starch enzyme.. 0.5% cellulose enzyme + 0.5% neutral protein enzyme.. 0. 3% cellulose enzyme + 0.3% starch enzyme + 0.4% neutral protein enzyme in addition to basal diets; group V. VI.. VI were saltæ¢dding groups, whichwas respectively fed on 0. 1% ZnSO4. 0.4% Zn桵et,.. 0.2% Zn桵et3 + 0.05% ZnSO,, in addi- tion to basal diets. By 48 days?feeding experiment, the results showed: (Degg production, total egg weights and the rate of producing eggs of each enzymeæ¢dd- ing group were higher than those of group I obviously, the fertility rate and hatchability of hatching eggs of each enzyme-adding group were higher than those of group I ; in the meantime, the ratio of feed to egg and the number of pecked eggs and broken eggs of each enzymeæ¢dding group were lower than those of group I obviously. In addition, the carcass quality of each enzymeæ¢dding group was also better than that of group I (P>0. 05). (Kiln saltæ¢dding groups, egg produc- tion.. total egg weights and the rate of producing eggs of group Vi. Vll(chelated salt groups) were higher than those of group Vobviously , and the fertility rate and hatchability of hatching eggs of group VI. VI were higher those of group V; in the meantime, the ratio of feed to egg and the number of pecked eggs and broken eggs or group VI. VII were lower than those of group Vobvious[y. In addi? * tjon, the divergence of carcass quality of each saltæ¢dding group was not sir nificant (P>O. 05). So pheasants breeding function of each enzymeæ¢dding group and chelated salt group was improved obviously compared with that of relevant control groups (group I V), and their performance was also Improved. The re- sults also showed that the experimental effect of group ill was best in enzyme æ¢dding groups and the experimental effect of group VII was best in altæ¢dding groups. (2) 168 young pheasants (7 days old), the divergence of body weights being not significant (P>O.05), were divided randomly into 7 groups, with 21 pheasants in each one. Group I was only Fed on hasal (I iets; group II III-. IV were enzyme adding groups, which was respectively fed on 0. 5% cellulose enzyme ?0.5% neutral protein enzyme. 0.3% cellulose enzyme + 0.3% starch enzyme ?.4% neutral protein enzyme, 0.2% cellulose enzyme + 0.2% starch enzyme + 0.2% phytase + 0.4% neutral protein enzyme in addition to basal diets; group V~ \/J~ VII were saltæ¢dding groups, which was respect ively ted on 0. 1% ZnSO1, 0. 1% Zn桵et2. 0. 2% Zn桵et2 + 0.05% ZnSO1 in addition to basal diets. By 21 days?feeding experiment, the results showed: Gjthe average increasing weight per梔ay of each enzymeæ¢dding group was significantly higher(group 11) or much significantly higher (group III, IV) than that of group I (P<0.05), in the meantime, the ratio of feed to body weight was lower than that of group I, and grou...
