Graptoloid feeding efficiency, rotation and astogeny [PDF]

Lethaia, 1992
Two methods are used to examine feeding strategies in graploloids; the first profiles different sets of zooids on the colony, the second treats the colony as a whole. Both of these techniques have advantages. The choice between them brings into question our concepts of the degree of coloniality shown by graptoloids.

Evaluation of the Dietary Black Soldier Fly Larvae Meal (Hermetia illucens) on Growth Performance, Intestinal Health, and Disease Resistance to Vibrio parahaemolyticus of the Pacific White Shrimp (Litopenaeus vannamei)

Frontiers in Marine Science, 2021
The present study evaluated the effects of the dietary black soldier fly larvae meal (BSF) on growth performance, intestinal health, and susceptibility to Vibrio parahaemolyticus in the Pacific white shrimp Litopenaeus vannamei.

FEED EFFICIENCY OF FISH MEAL-II

NIPPON SUISAN GAKKAISHI, 1963
In this paper, the authors examined the digestibility of fish meal by a physiological method (with rainbow trout) and an artificial method (the pepsin method). Samples of white fish meal (flatfish) and brown fish meal (saury) were treated with or without several kinds of solvents (ether, petrolum ether, acetone, and benzene) separately, and stored in ...

Feed Sustainability and Efficiency

, 2023
As the world population approaches the projected 10 billion thresholds in 2050, it is anticipated that global food demand, particularly for protein, would increase dramatically in the ensuing decades. In terms of absolute and relative growth rates, poultry has outpaced the other major meat types produced globally over the past 50 years.

Negative effects of aflatoxin B1 (AFB1) in the diet on growth performance, protein and lipid metabolism, and liver health of juvenile hybrid grouper (Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂)

Aquaculture Reports, 2023
With the increasing consumption of plant-based ingredients in aquafeeds, aflatoxin B1 (AFB1) contamination has become an issue of concern. This experiment aimed to investigate the effect of dietary AFB1 levels on the growth and liver function of hybrid ...

Digestibility in selected rainbow trout families and modelling of growth from the specific intake of digestible protein [PDF]

, 2008
The experiments aimed to clarify variations in digestibility of dietary nutrients in rainbow trout. Furthermore, the objective was to study how differences in digestibility might be related to growth and feed utilisation at various growth rates.

Squalene activates Wnt/β-Catenin signaling pathway to mediate NF-κB pathway to regulate inflammatory response and disease resistance in hybrid grouper (♀ Epinephelus fuscoguttatus × ♂ E. lanceolatu)

Aquaculture Reports, 2023
We previously found that squalene may influence immunity of grouper by affecting the Wnt/β-Catenin signaling pathway, but the exact mechanism is uncertain.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.
