<b>Optimization and Comprehensive Evaluation of Compost</b><b> </b><b>Bedded Pack System for Dairy Farming</b>
Listed in figshare
<p dir="ltr">Large?scale adoption of compost bedded pack (CBP) barns for dairy production in China is constrained by insufficient localized management protocols, seasonal parameters and quantitative multi?benefit assessments.
Description
This study combined simulation, response?surface optimization and on?farm trials to optimize CBP bedding management under humid subtropical conditions in eastern China, evaluating bedding environment, cow welfare?health, production performance, manure reduction and economic returns.
The bedding?surface?temperature model built from simulation achieved field?validated performance of R2= 0.995 and RMSE = 1.6 ℃. Season?specific ventilation?bedding?thickness combinations for spring?autumn, summer and winter were obtained, with measured?predicted bedding moisture relative errors below 5% for each optimum. Relative to conventional freestall (FS), CBP increased stall utilization index by 9.67%.

Hygiene score improved by 38.14% on day 20 and 53.19% on day 40. Milk yield rose 8.26% at day 40. CBP reduced mastitis and hoof?disorder risks without changing milk composition or somatic cell count.
Manure source?reduction reached 63.5% for lactating cows and 75.8% for replacement heifers. CBP capital cost was 1.9% lower than FS, yet higher operating costs drove a 26.79% increase in 5 year full life cycle total investment. In conclusion, CBP delivers benefits in animal welfare, disease control and manure abatement but is limited by high operating expenses.
Season?specific refined management is required to lower operational costs. This work provides empirical evidence for standardized green intensive dairy farming in China.</p>
