A combination of machine learning algorithms was first used to elucidate the mechanism of signature microorganisms and their symbiotic partners to promote the rumen volatile fatty acids production and rumen function development in early feeding lambs, providing insights into the ruminant rearing theory.

Comparing taxon-level contribution profiles of (A) (B) (C) rumen functional shifts

Plant protein diet suppressed immune function by inhibiting spiral valve intestinal mucosal barrier integrity, anti-oxidation, apoptosis, autophagy and proliferation responses in Amur sturgeon (Acipenser schrenckii), and thereby increased mortality. These findings guide a nutritional intervention for application of plant protein in diet of Amur sturgeon. Honeybee reproductive investment reveals the regulatory mechanism of trait that genetic selected bees for increasing royal jelly production (RJBs). The nurse bees of RJBs evolve a stronger olfaction to sense and response to brood pheromones than that of non-selected Italian bees (ITBs), which increases the larval acceptance rate and boosts the royal jelly production in turn. This is driven by the induced olfactory function in RJBs of chemosensation and energy meta relative to (ITBs). These findings reveal novel aspects of pheromonal communication in honey bees and explain how sensory changes affect communication and lead to a drastic shift in colony-level resource allocation to sexual reproduction. It is a unique feature that fat can be deposited in sheep tails or rumps and thereby adapt to the environment. The major genes related to sheep tail types were identified from the genome level using the Mongolian sheep. The findings elucidated the molecular mechanism of tail fat deposition in sheep.
