Optimizing Nutrient Modeling in Organic Pig Production through Refining Feeding Strategies
Abstract
Organic pig farming practices are linked to significant ammonium losses, leaching of nitrates in sow pasture designs, and a reliance on imported proteins feed ingredients like soybean cake. Additionally, there is a shortage of information on leakage variables and models that take into consideration nutrient balancing for organic farming processes in ecological nutrient modeling methodologies. As a result, the current research was aimed at investigating feeding practices in sustainable pig farming using sophisticated nutritional modeling techniques. Six consuming circumstances were examined using a Eco balance analysis life cycle method: Reduced non-degradable protein in food sources for female pigs and porkers (S1), reduced proteins concentrations in food sources for female pigs and porkers (S2), and reduced the amount of compound food that female pigs and female pigs and porkers consume (S5 and S6, respectively). Typical production data were acquired, and information on organic production (nitrogen levels in manure, pigsty and residence ammonia emission factors) was found. Sucker, porkers, feed, compost, and inputs production were the six components that were taken into account and regulated properly. Five ecological impact categories were evaluated: land occupancy, Eutrophication potential (EP), Acidification potential (AP), Abiotic factors depletion (AD) of fossil fuels, and climate alteration (CA)(including changes in soil carbon).It was shown that in comparison to merely adding female pig, the feeding techniques had noticeably greater results when incorporating both female pig and developing piglets. The lowest amounts of compound feed to female pig and growing pigs were predicted to be responsible for the greatest reductions for the majority of the evaluated environmental effects.
