Alteration of growth performance and characterization of pathological lesions in long-term ammonia-exposed pigs.

Ammonia (NH) is a major cause of odor emissions from swine farms, and exposure to high concentrations of NH in short-term periods has been reported to cause respiratory and systemic disorders in pigs. However, the impact of long-term NH exposure on pig health and productivity remain unknown. This study aimed to assess the impact of long-term NH exposure on growth performance and pathological outcomes in pigs.

Effects of benzoic acid in pig diets on nitrogen utilization, urinary pH, slurry pH, and odorous compounds.

Objective: The objective was to investigate the effects of dietary benzoic acid (BA) on nitrogen (N) balance, urinary pH, slurry pH, and odorous compounds in feces and slurry of pigs.

Methods: Twelve barrows with an initial body weight of 56.2±2.

Effects of Supplemental Benzoic Acid, Bromelain, Adipic Acid, and Humic Substances on Nitrogen Utilization, Urine pH, Slurry pH, and Manure Odorous Compounds in Pigs.

The objective was to evaluate the effects of benzoic acid, bromelain, adipic acid, and humic substance supplementation on nitrogen balance, urinary pH, slurry pH, and manure odorous compounds in pigs. Fifteen castrated male pigs with an initial body weight of 37.9 kg (standard deviation = 4.
