Analysis of energy storage and agricultural and animal husbandry profits

Does large-scale livestock husbandry have better economic performance than specialized farms?

Our results indicate that large-scale livestock husbandry shows better economic performance but worse environmental consequences than the backyard and specialized farms. In other words, the larger production scale causes better economic benefits and worse environmental consequences.

Does feed cost affect the economic profit of pig husbandry?

The cost of feed accounts for greater than 80% of the total cost for the SF, TF and HTF but 60.1% for the BF. Clearly, the feed cost is the primary factor to affect the economic profit of pig husbandry. The main difference derives from the commercial feeds and soybean meal.

Does large-scale livestock husbandry improve pig production?

In this study, the LCA, EME and ECA methods provide three different but complementary standpoints to compare pig production with different models. Our results indicate that large-scale livestock husbandry shows better economic performance but worse environmental consequences than the backyard and specialized farms.

What is energy assessment of agricultural production system?

Energetic assessment of agricultural production system can embrace different forms of energy account that follow the first and, in some cases, the second law of thermodynamics. Ten approaches are identified and are presented according to the energy accounting: (i) energy, (ii) exergy, and (iii) emergy.

What role does energy play in farm systems?

A review Energy holds a key role in farm systems. Cultivation is based on the conversion of solar energy into biomass of interest. Fossil energy allows mechanized and high-yield agricultural production system, but has a strong impact on climate change, and its supply is compromised in the next decades.

What is the role of energy in agricultural production system?

Energetic assessment of the agricultural production system. A review Energy holds a key role in farm systems. Cultivation is based on the conversion of solar energy into biomass of interest.
