Livestock Products Technology- ICAR JRF/SRF 2024

MCQ (Single Correct)

Which of the following is NOT a significant contributor to greenhouse gas emissions from livestock farming?

Carbon dioxide Correct Methane Nitrous oxide Ammonia

Carbon dioxide ($CO_2$): Directly respired by animals but constitutes part of the short-term biogenic carbon cycle (rapidly re-absorbed by feed crops through photosynthesis), making direct livestock $CO_2$ a non-significant net anthropogenic greenhouse driver compared to enteric methane and nitrous oxide. (Correct answer)
Methane ($CH_4$): A potent greenhouse gas heavily produced by enteric fermentation in ruminants and anaerobic manure lagoons.
Nitrous oxide ($N_2O$): An exceptionally potent greenhouse gas emitted during the storage, handling, and application of livestock manure and urine.
Ammonia ($NH_3$): A significant livestock-related atmospheric pollutant and indirect greenhouse contributor causing soil acidification.
