INTRODUCTION Livestock sector contribution has increased in total agriculture and allied sector of GVA (Gross Value Added) from 24.32 % (2014-15) to 28.63 % (2018-2019). Livestock sector contributed 4.19 percent of total GVA in 2018-19 (National Accounts Statistics, 2020). The demand for green and dry fodder will reach to 1012 and 631 million tonnes respectively by the year 2050. The deficit of green and dry fodder will be 18.4 % and 13.2 % respectively in the year 2050. To meet out the deficit, green forage supply need to grow at 1.69% annually (IGFRI Vision, 2050). Micronutrients is important for plant growth and among the micronutrients, zinc is one of the most essential minerals for soil and plant health. Application of zinc fertilizer is needed for higher crop yield and better crop quality. Biofortification of soil with zinc fertilizers enhance zinc content in plants (Alloway, 2008). Foliar application of zinc sulphate improve productivity of crop (Sharma and Singh 2018). Zinc is a very important for growth, reproduction and immune response in ruminants (Underwood and Suttle 1999). Some of the studies (Gowda et al., 2000; Yadav and Khirwar 2005) stated that a close relationship between soil zinc content, plants and animals. One health concept summarizes that animal health, human health and environmental health are intrinsically intertwined and interdependent. The health of one affects health of all. In India, indiscriminate use of nitrogen fertilizer along with zinc deficiency decrease the growth of fodder. As per the report of All India Coordinated Research Project (AICRP) about 40% of soil samples collected across India are deficient in available Zn (Shukla et al., 2016) results in livestock are concurrently reported (Rakesh et al., 2017) zinc deficiency. Hence, the objective of this study was to enrichment of zinc in fodder sorghum through soil and to study the effect of zinc enriched fodder on growth performance in post weaning growing goat. MATERIALS AND METHODS The experiment was conducted in 10 locations of Peramandampalayam village of Mohanur block at Namakkal district and 10 locations considered as replications of experiment group. The soil and water samples were taken from respective locations, analyzed the results was presented in Table 1. The two treatment groups were T1: Farmers practice (FP) was farm yard manure @ 15t/h and urea 50 kg/ha and T2: T1 + Zinc sulphate @ 20 kg/ha. The 50 kg of nitrogen was split in two doses and applied as top dressing. Zinc sulphate was mixed with farmyard manure applied at the time of sowing. Fodder sorghum (COFS 29) was sown in the field on October in 2020. Fodder sorghum (COFS 29) was harvested at 60 days after sowing. Harvested fodder was weighed, chaffed, shade dried and stover was fed to the goat as per the treatment groups for 60 days. All post weaning growing kids were maintained in uniform conditions with well ventilated housing. All growing kids were dewormed before start of experiment. All growing kids were weighed monthly by using weighing balance. RESULTS AND DISCUSSION Zinc enriched soil not significantly enhanced green fodder sorghum yield and dry matter yield of fodder sorghum compared to farmers practice (Table 2). In contrast to results of the present study Verma et al. (2005) reported that zinc enriched soil significantly increased fodder yield and dry matter content of fodder sorghum. Giridhar et al. (2021) stated that zinc enriched soil increased dry matter yield of fodder sorghum. The application of zinc sulphate in soil increased concentration of zinc in the fodder sorghum but, not significantly compared to farmers practice (Fig. 1). The zinc content was higher in zinc enriched fodder sorghum (27.25 mg/kg) compared to farmers practice without zinc fortification (22.75 mg/kg). However, Giridhar et al. (2021) observed zinc enriched soil significantly increased zinc concentration in fodder sorghum. Zinc enriched fodder sorghum did not significantly increased average daily concentrate intake, average daily green fodder intake and total dry matter intake of growing kid over farmers practice (Table 3). Similarly, Giridhar et al. (2021) reported that feeding of zinc enriched fodder not influenced dry matter intake of sheep. At the start of feeding experiment, the initial body weight of T1 and T2 groups were 8.5 kg and 8.4 kg respectively (Table 4). At the end of experiment, body weight (kg) and average daily gain (kg) of zinc enriched fodder sorghum fed group was slightly increased, but not significantly over farmers practice. In contrast, Giridhar et al. (2021) stated that zinc enriched fodder sorghum significantly increased final body weight and (kg) and average daily gain (kg) over control. The dietary supplementation of zinc methionine improved growth performance in goat (Wenbin et al., 2009). Feeding of zinc enriched fodder sorghum increased net return and B:C ratio as compared to farmers practice (Table 5). The reason for slight increase net return might be due to high yield of fodder sorghum and increased final body weight of post weaning growing kid.
