Growth Performance, Metabolomics, and Microbiome Responses of Weaned Pigs Fed Diets Containing Growth-Promoting Antibiotics and Various Feed Additives.

The objective of this study was to determine the potential biological mechanisms of improved growth performance associated with potential changes in the metabolic profiles and intestinal microbiome composition of weaned pigs fed various feed additives. Three separate 42 day experiments were conducted to evaluate the following dietary treatments: chlortetracycline and sulfamethazine (PC), herbal blends, turmeric, garlic, bitter orange extract, sweet orange extract, volatile and semi-volatile milk-derived substances, yeast nucleotide, and cell wall products, compared with feeding a non-supplemented diet (NC). In all three experiments, only pigs fed PC had improved ( < 0.

Experimental facility had a greater effect on growth performance, gut microbiome, and metabolome in weaned pigs than feeding diets containing subtherapeutic levels of antibiotics: A case study.

The objective of this study was to define changes in the intestinal metabolome and microbiome associated with growth performance of weaned pigs fed subtherapeutic concentrations of antibiotics. Three experiments with the same antibiotic treatments were conducted on the same research farm but in two different facilities (nursery and wean-finish) using pigs weaned at 20-days of age from the same source herd and genotype, and fed the same diets formulated without antibiotics (NC) or with 0.01% chlortetracycline and 0.

Assessing the frequency with which primary care providers address sleep of infants and young children.

Sleep problems during early development are common and associated with negative health outcomes. Earlier recognition of poor sleep health permits earlier intervention and improved outcomes. This retrospective cohort study aimed to identify the frequency with which primary care providers assessed sleep health when completing the Rourke Baby Record for infants and young children during routine well-baby visits from 2002 to 2019.

Abortion Access for Incarcerated People: Incidence of Abortion and Policies at U.S. Prisons and Jails.

Objective: To understand abortion incidence among incarcerated people and the relation to prison and jail pregnancy policies.

Methods: We collected abortion numbers and policy data from convenience sample of 22 state prison systems, all Federal Bureau of Prisons sites, and six county jails that voluntarily reported monthly, aggregate pregnancy outcomes for 12 months in 2016-2017. Sites also completed a baseline survey of institution characteristics and pregnancy policies, including abortion.

Effects of intense pulsed light and gamma irradiation on Bacillus cereus spores in mesquite pod flour.

This study was conducted to evaluate the inactivation of Bacillus cereus spore in mesquite flour with intense pulsed light (IPL) and gamma radiation. The physical, chemical, and toxicity of treated mesquite flour were also investigated. The results showed that up to 3.
