Resumen
Objective: To evaluate the production of total gas, methane (CH4), and in vitro fermentative variables in diets for sheep with 1 and 2% sunf lower oil.
Design/Methodology/Approach: Serological pipettes with 0.5 g of treatment and 50 ml of culture medium were incubated at 39 °C for 24, 48, and 72 h. The production of total gas, CH4, and degradation of dry matter (DEGDM), neutral detergent fiber (DEGNDF), acid detergent fiber (DEGADF), as well as the production of volatile fatty acids (VFA) and ammoniacal nitrogen (N-NH3) were estimated. The experimental design was completely randomized.
Results: Total gas production increased (p0.05) at 48 and 72 h and decreased (p0.05) at 24 h as the oil increased. CH4 production at 24 and 48 h did not present differences (p0.05); a linear decrease (p0.05) was quantified at 72 h. DEGDM increased (p0.05) at 24 and 48 h and decreased (p0.05) at 72 h. DEGNDF and DEGADF increased (p0.05) at 48 h. Butyric acid content and N-NH3 decreased (p0.05) at 48 h.Study Limitation/Implications: A 2% inclusion of sunf lower oil in the diet can reduce the degradability of the food and the microbial protein.
Findings/Conclusions: Including up to 2% of sunf lower oil in diets for lambs does not affect the fiber degradation and is an alternative to reduce the amount of methane emissions released into the environment.
