The global pork production is expected to rise by 10% over the next decade. Given, however, that pig farmers worldwide are currently struggling to keep up with increasingly stringent regulations on nitrogen (N) pollution emission, now is clearly not the time to rest on our laurels, rather for a sober reality check. Put simply - more pigs will mean more N excretion, meaning pig farmers will soo...
Congratulations. Actually, I´m working in composting necromass as biosolids to produce an organic fertilizer which is employed inside our pig farm to produce corn to feed pigs.
If the biopile is designed and arranged properly, the fermentation process is not stimulated but the respiration process is activated. So, the N emissions are reduced. However, I think it is very important to reduce the N level in diets to obtain a better gut environment and improve the pig health in the operation.
Vargas Alejandro Thank you for the good comment. Composting of manure (necromass) as biosolids to produce an organic fertilizer (or for producing biogas) a sustainable way to minimize the N excretion to the environment. As you mentioned, lowering CP level in weaned pigs diets in combination with gut health promoting additives is a strategy to improve gut barrier function and control post-weaning diarrhea in weaned pigs. Kind regards.
