Effects of multienzyme supplementation on energy and nutrient digestibility in various feed ingredients for pregnant gilts.

The utilization of exogenous fiber-degrading enzymes in commercial swine diets is a strategy to increase the nutrient and energy density of poorly digestible ingredients. In a prior set of studies, dietary multienzyme blend (MEblend) supplementation increased the apparent total tract digestibility (ATTD) of nutrients, non-starch polysaccharides, and energy in complete high-fibrous gestation diets by 6% when fed to gestating sows. The current study aimed to determine the effects of MEblend (containing xylanase, β-glucanase, cellulase, amylase, protease, pectinase, and invertase activities) supplementation on ATTD of energy and nutrients of individual feedstuffs commonly used in gestating sow diets across major pork-producing regions worldwide, which differ in their fibrous components.

Combined associations of takeaway food availability and walkability with adiposity: Cross-sectional and longitudinal analyses.

Background: Diet and physical activity are important determinants of energy balance, body weight and chronic health conditions. Peoples' health and behaviour are shaped by their environment. For example, the availability of unhealthy takeaway food in residential neighbourhoods and the ability to easily walk to a range of local destinations (high "walkability") influence diets and physical activity levels.

Barriers to Research Faced by High-Income Versus Low- and Middle-Income Country Otolaryngologists and Otolaryngology Residents.

Objective: This study aims to compare research productivity and barriers to research between high-income countries (HICs) and low- and middle-income countries (LMICs) otolaryngologists.

Study Design: Cross-sectional survey.

Setting: International survey.

Metabolizable energy and digestible nutrient values of protease-supplemented field pea for broiler chicken.

A study was conducted to determine the effects of protease supplementation of field pea (in comparison with soybean meal; SBM) for broilers on apparent metabolizable energy (AMEn) and standardized ileal digestibility (SID) of amino acids (AA). One hundred and forty broiler chicks were divided into 35 groups of 4 birds/group and fed 5 diets in a completely randomized design (7 groups/diet) from 14 to 21 d of age. The diets were cornstarch-based containing SBM or field pea as the sole protein source without or with protease (ProSparity 250; CBS Bio Platforms, Calgary, AB, Canada) in 2 × 2 factorial arrangement, and N-free diet.
