Effects of Capsicum oleoresin Inclusion on Rumen Fermentation and Lactation Performance in Buffaloes (Bubalus bubalis) during Summer: In Vitro and In Vivo Studies

This research aimed to evaluate the effects of Capsicum oleoresin (CAP) supplementation on rumen fermentation in vivo and In vitro, lactation performance buffaloes. experiment 2 × 5 factorial design was carried out according two temperatures (normal temperature: 39 °C; hyperthermal 42 °C) five CAP concentrations (0 mg/L; 20 200 2000 mg/L). vivo, four multiparous mid-lactating Mediterranean buffaloes (body weight: 640.08 ± 17.90 kg) were randomly allocated treatments 4 Latin square for dosages mg/kg, 10 or 40 mg/kg dry matter). The experiment’s results vitro showed that temperature affected all characteristics measured this research. decreased pH, short-chain fatty acids concentration, percentages propionate, butyrate, isobutyrate, valerate, caproate, while increasing percentage acetate ratio propionate at normal (p ≤ 0.05). quadratically fluid reduced rectal respiratory rates 0.05) tended increase matter intake 0.10). For performance, increased milk yield lactose 0.05), protein conclusion, modified had beneficial during summer.
