摘要

Compost-bedded pack (CBP) barns for dairy cowsmainly use sawdust as bedding material. The objectiveof this study was to compare forest biomass tosawdust as bedding material for CBP. Variables evaluatedincluded CBP moisture, temperature and C:Nratio, bedding microbial counts, and behavior andwelfare measures of nonlactating cows. The experimentaldesign was a crossover where two 11-wk periodswere performed. Treatments were CBP with sawdust(CBP-S) as a control treatment and CBP with forestbiomass (CBP-FB) as the experimental bedding material.Weather conditions, intake, CBP temperature,CBP moisture, and welfare assessment were measuredduring the entire periods. We took CBP samples for microbiologicalanalysis and video recordings for animalbehavior assessment in wk 11 of each period. The CBPmanagement was the same in both treatments and periods,based on twice-daily tilling at a 30 cm depth, andthe addition of 0.8 kg/m~2 of new bedding material perday. Ambient temperature and environmental humiditywere 9.1°C and 82.5% in period 1, and 13.2°C and75.3% in period 2. Average DMI and water consumptionwere 17.4 ± 0.86 kg/d and 50.9 ± 7.84 L/d inperiod 1, and 16.3 ± 0.96 kg/d and 56.3 ± 8.02 L/d inperiod 2. Average of temperature, moisture, and C:Nratio of CBP were 32.2°C, 63.6%, and 44:1 in CBP-S,and 24.3°C, 66.4%, and 35:1 in CBP-FB, respectively.Temperature was higher in CBP-S than in CBP-FB,and in period 2 compared with period 1. Moisture washigher in CBP-FB than in CBP-S in period 1, but didnot differ between treatments in period 2. The C:Nratio was higher in CBP-S than in CBP-FB in bothperiods. Total bacteria count and Bacillus spp. weresimilar between treatments. Klebsiella spp. counts inCBP-S were higher than in CBP-FB, and Streptococcusspp. and yeasts and fungi counts in CBP-S were lowerthan in CBP-FB. Total coliforms, Escherichia coli, and Staphylococcus aureus counts in CBP-S were higherthan in CBP-FB in period 1, but did not differ betweentreatments in period 2. No differences were detected inlying time (15.5 h/d), and time needed to lie down washigher in CBP-FB (5.3 s) than in CBP-S (4.6 s). Wefound that CBP performance and cow comfort in CBPFBwere lower than in CBP-S, but microbial counts ofsome species were better controlled in CBP-FB than inCBP-S.
