| The economics of Arbas County of Otog Banner in Ordos City,Inner Mongolia is mainly based on the Arbas Cashmere Goat industry.In order to understand the effects of different feeding modes on the production performance and economic benefits of the Arbas cashmere goats,60 healthy cashmere herd with half male and half female were selected randomly for one-year feeding trial in a herdsman in the Sumu from the end of June 2018.Conduct a one-year trial.In this paper,some experimental data were provided for the reproductive performance and nutritional status of Arbas cashmere goats under indoor stock keeping and grazing feeding mode.The concentrations of reproductive hormones and serum mineral elements in cashmere goats were tested to determine the effects of different feeding patterns.On the reproductive and nutritional status of cashmere goats.The results showed that there were significant differences in the concentrations of estradiol(E2),prolactin(PRL)and prostaglandin E2(PGE2)between indoor stock keeping and grazing groups in August and October.p<0.05);there was a significant difference in the concentration of testosterone(T)between prolactin(PRL)and ram in December(p<0.05).Except for August,estradiol(E2),prostaglandin E2(PGE2),prolactin(PRL)and progesterone(P4)concentrations were higher in Indoor stock keeping sheep than in grazing sheep.The results showed that there were significant differences in the concentrations of iron,copper and magnesium in the indoor stock keeping and grazing groups in August(p<0.05).In October,zinc,calcium and magnesium were used.There was a significant difference in the concentration of phosphorus(p<0.05).There was a significant difference in the concentrations of iron,zinc,magnesium and phosphorus in December;there was a significant difference in the concentration of zinc and magnesium in March(p<0.05).In the four periods,the concentrations of zinc,copper and phosphorus were higher in the indoor stock keeping flock than in the grazing flock;except for August,the concentration of iron and magnesium was higher than that of the grazing sheep. |
