| Experiments were conducted with four six-month old LiaoNing cashmere goats with average live weight of 17kg who were fitted with permament runinal and cerum fistulae. Experiments were conducted by the design of 4x4 Latin square .The experimen was composed of four group .there were cysteamine group ,Daidzein group , combination group and control group respectively. Each experimental group was feed by the same basic fodder.The cashmere goats in the control group was only feed with basic fodder,while the Da group feed with basic fodder added with daidzein 3mg/kg evry day ,the CS group feed with the basic fodder added with cysteamine lOOmg/kg W.B one time evry week,the combination group feed with the basic fodder added with cysteamine (lOOmg/kg W.B) one time evry week and daidzein(3mg/kg) every day.The experiment had four periods ,each had twenty-one days for trail,seven days for break .In this experment,effects of cysteamine and combination on the gain weight of LiaoNing cashmere goats were studied;Effects of the additives on the digestion and metabolism ,the physical quality of down and hair and the road of cysteamine metabolism in the cashmere goats were studied.In order to give some scence numbers for found a way to increase the gain weight and the produce and improve quality of down in LiaoNing cashmere goats. The result was following:Effects of cysteamine and combination on the gain weight of the LiaoNing cashmere goats.The Cs group increased 22.22 percent than the control group, There was significant different between control group and Cs groupthe combination increased 16.67 percent than the control groupas ,there was significant different (P<0.05).The results indicated that the cysteamine and cimbination could increased the gain weight of LiaoNing cashmere goats.Cysteamine and combination infulunced on ruminant inner surroundings.The chang of pH value is the same between three group duing a day. The pH value of Cs group increased 1.45 percent .compared with contronl group.But no significant different between the two group(P>o,o5). The concentration of NH3-N of Cs group compared with control group was decreased 10.23 percent There was significant different between the two group(P<0.05). The concentration of NHs-N of combination group is higher 62.21 percent than the concentration of control group.There was significant different between them.(P<0.05). The concentration of total protein of CS group and combination have a increase than control group, increasing 22.76 percent and 15.76 percent respectively. There were significant different between them(P<0.05). Three groups have the same chang about -SH-group concentration during a day. Compared with control group .ruminal -SH-group concentration of Cs group and combination group increased 35.56% percent and 21.65% percentThere were significant different between them(P<0.05).Effects of cysteamine and combination on cecum inner surroundings in LaoNing cashmere goats.AH groups have same chang on pH value.Though Cs group and combination have some increse compared with control group,there were no signicant different between them.(PX).05). Three group had a same chang about the concentration of cecum TCA-P .they all had a mixmum in one hour to two hours after feeding respectively,while had a minmum after three hours,but there was no deffent between them. At the same time,Cecum concentration of TCA-P of Cs group increased 5.2 percent than control group, while cecum concentration of TCA-P combination group was lower than control group. Compared with control group,Cs group and combination group were increased 9.92 percent and 9.09% repectively than control group.But there were no significant different among them(P>0.05).The result suggested that cysteamine and combination did not affect on cecum -SH-concentration.Effects of cysteamine and combination on blood plasma insulin concentration and blood plasma T3 concentration of cashmere goats. Compared with control group.The insulin concentration of Cs group and combination group increased 16.85 percent and 11.18 perc... |
