Nutritional evaluation and rumen parameters of plum pomace in goats
The objective of the work was to evaluate the nutritional composition of plum pomace, total digestibility and dry matter degradability and fiber fraction in goats. Four goats were used and two diets were fed: alfalfa-based hay (SOC, by its acronym in Spanish); alfalfa-based hay + plum pomace (0.5% of PV/day) (COC). Total consumption, apparent total digestibility in vivo, rumen degradability in vitro of dry matter and neutral detergent fiber were determined at 24 and 48 hours of incubation. The consumption of the alfalfa-based hay, the total dry matter and the substitution rate did not show differences between treatments (p=0.143; p=0.540 and p=0.528, respectively). The total apparent digestibility of the dry matter consumed between the COC and SOC treatments showed similar values (p=0.881). The in vitro rumen degradability of the dry matter of plum pomace at 24 and 48 h of incubation was similar to the alfalfa-based hay. The in vitro ruminal degradability of NDF (Neutral detergent fiber) from alfalfa roll at 24 hours of incubation did not show differences (p>0.05) between COC and SOC. The degradability of NDF after 48 h of incubation showed lower values in COC (p<0.05). The plum pomace verified a slight substitution effect, reducing the ruminal degradability of alfalfa hay fiber, without modifying the apparent total digestibility of the dry matter consumed. The animals did not show symptoms of toxicity, thus allowing waste to be converted into a resource for goat feeding.
