Context: Biochar can affect the storage and forms of nitrogen; thus, it may also play a role in altering nitrogen cycle during fermentation process cow dung into organic fertilizer. Objective: To elucidate mechanism transformation composting manure with biochar, comparative experiment was conducted. Method: This study investigates use biochar as medium to enhance aerobic manure. The effectiveness verified through rapid experiment. Result Conclusions: results demonstrated that adding 5% compost pile increased total content by 12%. Specifically, pyrrolic composted from 38% 44%, carbon-nitrogen ratio improved 35% 37%. Analysis surface functional groups indicated C=O C=C bonds played key modifying storage. Microbial analysis showed could significantly regional competitiveness microorganisms, such Cellvibrio, thereby boosting expression genes involved nitrification process, including amoABC, hao, nxrAB. Therefore, not only enhances fertilizer but changes microbial population structure. Significance: carries substantial implications for application field, well development fertilizers based on

Two periods enrolling 56 (milk yield 36.2 ± 7.91 kg/d) and 58 32.4 4.99 grouped-fed dairy cows were performed to evaluate nutrient adjustment N emissions of a precision feeding strategy. Pens blocked by parity randomly assigned conventional (CONV) or scheme (PREC) for 21-d period. The CONV group was offered total mixed ration (TMR, 6.82 6.65 MJ NEl/kg DM, in period 1 2, respectively, 165 g CP/kg DM both periods; whereas PREC fed partial (PMR, 6.40 135 137 respectively) concentrate feed supplemented twice daily the milking parlour, which contained different quantities soybean meal, corn wheat middling's according estimated nutritional needs each cow above those supplied consumption PMR. Individual nutrients consumed from PMR calculated using 10-d rolling average performance data concentration its components, BW recorded periods). A balance urine fecal spot sampling during last 3 d study 1, stored manure gaseous (ammonia, methane, nitrous oxide, carbon dioxide) measured 2 wk 2. After adaptation diet, 82 homogeneously distributed 4 DIM categories: early (< 81), mid-early (81 150), mid-late (151 220), late (> 220) used assess how energy protein requirements adjusted system. Dairy systems energetically overfed, tended be more CP overfed than cows. Total excretion, milk urea greater There no differences ammonia oxide storage between cows; however, methane dioxide increased 55 15%, respectively Precision system based on preceding composition can reduce excretion without affecting short-term but increasing C manure.

The objective was to evaluate the effects of separate offering feed ingredients (SF) and frequency concentrate feeding versus a TMR, on lactational performance, ruminal fermentation, enteric CH4 emissions, nutrient digestibility, N use efficiency, milk fatty acid profile, blood variables in mid-lactation dairy cows. Twenty-four Holstein cows (12 primi- 12 multiparous) averaging (±SD) 141 ± 35 DIM 43 6 kg/d yield (MY) at beginning study were used replicated 3 × Latin square design experiment with periods 28 d each, composed 7 for adaptation diets, 11 estimation net energy metabolizable protein requirements, 10 data samples collection. Cows grouped based parity, DIM, MY into 4 squares. Treatment allocation balanced carryover effects, within assigned (1) basal diet fed ad libitum as TMR; (2) SF forages concentrates 3×/d (SF×3); or (3) 6×/d (SF×6).
