    TLDR Gaining 5-10 kg during the non-growing period boosts cashmere yield and length in goats.
    The study investigated the impact of body weight gain during the cashmere non-growing period on cashmere production and secondary hair follicle activity in 50 Inner Mongolian cashmere goats. Results showed that goats with a weight gain of 5.0-10.0 kg had a 17.10% increase in cashmere yield and an 8.09% increase in cashmere staple length compared to those with a 0-5.0 kg gain, with no significant difference in cashmere diameter. Additionally, there was a strong positive correlation between body weight gain and the population of active secondary hair follicles. The study concludes that nutritional manipulations, such as supplementary feeding during the non-growing period, can enhance cashmere production performance, though further research is needed to optimize these nutritional strategies.
