Large animals are more efficient at digestion than small animals, because food spends more time in their digestive systems.
An interaction effect between test block and technique showed that the animals became more efficient with pushing after the first test block whereas the efficiency of pulling remained constant over the different test blocks (Appendix Table A8).
the specific processing and presentation of feed that make its conversion to animal products more efficient and increase growth rates and production yields.
In each of these cases, when farmers slaughter animals they do not generally cease to own livestock assets, but simply shift from ownership of an older less efficient animal to a younger more efficient animal.
With video, cheaper drones and software, identifying animals has become more efficient.
"The idea is to create animals that are more efficient," Rolf said.
Faster growing animals are generally more efficient as proportionally less energy is required for maintenance.
Other studies using il10 knockout mice showed that these animals have a more efficient control over the infection by T. cruzi, reducing parasitism levels with a significant increase in the secretion of IFN- γ, TNF- α, IL-12, and NO [ 48, 49].
In the Dutch outbreak, several factors were considered to have contributed to the increase in Q fever cases, including: (i) the high density of farms in the regions where the bacterium is endemic, (ii) asymptomatic infection in the majority of infected animals, and (iii) more efficient diagnostic tests [ 2, 6, 7].
Iron plows and sickles indicate the use of animals in farming and more efficient harvesting methods.
