Effects of ambient temperature on the growth performance, fat deposition, and intestinal morphology of geese from 28 to 49 days of age

Effect of parent flock age on hatching, growth rate, and features of both sexes goose carcasses

“…Females are predisposed to accumulate abdominal fat faster than males ( Liu et al, 2011 ). This trait may also be influenced by the age of the birds, environmental conditions, and breed ( Liu et al, 2022 ). Different levels of the share of abdominal fat in both sexes of geese may be the result of different use of energy and the ability to accumulate adipose tissue ( Madsen and Klaassen, 2006 ).…”

Effects of drinking water temperature in winter on growth performance, water consumption, surface temperature, and intestinal development of geese from 21 to 49 days of age

“…Intestinal morphology and digestive enzyme activity in poultry are closely associated with digestive and absorptive capacity, which were the important factor reflecting growth performance ( Deng et al, 2012 ; Song et al, 2018 ; Liu et al, 2022 ). However, similar results were found in the variation among intestinal digestive enzyme activity, intestinal development, and growth performance of geese.…”

Insoluble fibre and enzyme supplementation in mash or pellets diets on growth performance, apparent ileal digestibility and intestinal morphology of broiler chickens fed barley containing diets

“…At the end of 42 days, the duodenum and jejunum segments were collected and analysed according to Liu et al ( 2022 ). Briefly, 1 cm sections from the middle portion of the duodenum and jejunum tissues were fixed in 10% formaldehyde phosphate buffer after washed with 0.1 M phosphate buffered saline, and the fixed sections were processed, dehydrated, embedded in paraffin wax, sectioned at 5 mm, and stained with the haematoxylin–eosin.…”
