[EN] Pig slurry is a valuable fertilizer for crop production but at the same time its management may pose environmental risks. Slurry samples were collected from 77 commercial farms of four animal categories (gestating ...
Effects of nutrition on digestion efficiency and gaseous emissions from slurry in growing pigs: II. Effect of protein source in practical diets

Beccaccia, A.; Cerisuelo García, Alba; Calvet Sanz, Salvador; Ferrer Riera, Pablo; Estellés, F.; Blas, Carlos de; Garcia-Rebollar, Paloma (Elsevier Masson, 2015-11)

This research aimed to investigate effects of protein source in practical diets on nutrient excretion and potential emissions of ammonia (NH3) and methane (CH4) in pigs. Three experimental feeds were designed to substitute ...
Effects of nutrition on digestion efficiency and gaseous emissions from slurry in growing pigs: III. Influence of varying the dietary level of calcium soap of palm fatty acids distillate with or without orange pulp supplementation

Antezana Julián, Walter Orestes; Calvet Sanz, Salvador; Beccaccia, Amanda; Ferrer Riera, Pablo; Blas, Carlos de; García-Rebollar, Paloma; Cerisuelo García, Alba (Elsevier Masson, 2015-11)
