The experiment was conducted to investigate the influence of different levels of zinc (Zn) on cashmere growth, plasma testosterone and Zn profile in male Cashmere goats. Twenty-eight male Liaoning Cashmere goats, 3 years old and body weight at 56.2 ± 2.45 kg, were assigned to four groups. The animals were fed a basal diet containing of 45.9 mg Zn/kg dry matter (DM) basis and supplemented with 0, 20, 40 or 80 mg Zn (reagent grade ZnSO₄ ·7H₂ O) per kg DM for 90 days. There was no significant effect on growth and diameter of cashmere fibre for Zn supplemented in diets. However, the length and growth rate of wool were improved (p < 0.05) with dietary Zn. The length and growth rate of wool were higher (p < 0.05) for the groups supplemented with 40 or 80 mg Zn/kg DM compared with that of 20 mg Zn/kg DM treatment group. Plasma testosterone concentration was increased for Zn supplemented in diets, and the testosterone concentration was higher (p < 0.05) in goats fed on the diet supplemented with 40 or 80 mg Zn/kg DM compared with those fed on basal diet. Plasma Zn concentrations increased (p < 0.05) with increasing dietary Zn and supplemented with 40 and 80 mg Zn/kg DM groups improved plasma Zn concentration (p < 0.05) more than 20 mg Zn/kg DM group. Fibre Zn content was higher (p < 0.05) in groups supplemented with 40 or 80 mg Zn/kg DM compared with control group, but no difference between Zn-supplemented groups (p > 0.05). The activity of plasma alkaline phosphatase was increased (p < 0.05) due to dietary Zn supplementation; however, no difference was found between supplemented treatment groups (p > 0.05). In conclusion, Zn content (45.9 mg Zn/kg DM) in control diet was insufficient for optimal wool growth performance, and we recommended the level of dietary Zn for such goats is 86 mg/kg DM during the breeding season and cashmere fibre growing period.

“…It was shown that plasma Zn concentration was increased by Zn supplementation. Chhabra and Arora (1985) reported that plasma Zn concentrations were higher in goats fed a basal diet (15 mg Zn/kg DM) supplemented with 65 mg Zn/kg DM than in control goats. Similarly, Garg et al (2008) found that plasma Zn concentrations were higher in growing lambs fed a basal diet (34 mg Zn/kg DM) supplemented with 20 mg Zn/kg DM (ZnSO 4 or ZnMet) than in control lambs.…”

This experiment was designed to evaluate the effects of source of supplemental zinc (Zn) on performance, nutrient digestibility and plasma mineral profile in Cashmere goats during the cashmere fiber growing period. Twenty-seven Liao Ning Cashmere wether goats (9-10 month of age; initial BW = 19.31±0.32 kg) were fed a basal diet (containing 22.3 mg Zn/kg DM) with no supplemental Zn (control) or 20 mg of supplemental Zn/kg of DM from Zn sulfate (ZnSO 4 ) or Zn methionine (ZnMet) for 60 days including a 10-day metabolism trial. Average daily gain (ADG) (p<0.05) and gain:feed (G/F) (p<0.05) were increased by Zn supplementation, but no differences were noted between Zn sources (p>0.05). The length and diameter of cashmere fiber did not differ among treatments (p>0.05). Zn supplementation had no influence on digestibility of DM, CP, EE and NDF (p>0.05). However, ADF digestibility in the group supplemented with ZnMet was significantly higher than in other treatments (p<0.05). Plasma Zn was increased (p<0.05) and Cu tended to be decreased (p = 0.057) by Zn supplementation, but no differences were found between Zn sources (p>0.05). Plasma alkaline phosphatase activity (AKP) was improved by Zn supplementation (p<0.05) and was higher in the ZnSO 4 than the ZnMet group (p<0.05). Zn retention was increased (p<0.05) and apparent absorption rate was decreased (p<0.05) by Zn supplementation. The results indicate that supplementation of 20 mg Zn/kg DM either as ZnSO 4 or ZnMet in the basal diet containing 22.3 mg Zn/kg DM can improve growth performance in Cashmere goats, and effectiveness of the two sources is similar on performance measurements.
