Effect of diets containing commercial bioactive compounds on Salmonella Heidelberg infection in broiler chicks.

Salmonella Heidelberg (SH) is responsible for economic losses in poultry farming and food infections in humans and is a serious public health problem. Recently, there has been an increase in the frequency of isolation of this serotype in batches of broilers raised in Brazil. It is necessary to find new ways to help control this pathogen.

In ovo threonine supplementation affects ileal gene expression of nutrient transporters in broilers inoculated post-hatch with Salmonella Enteritidis.

The effect of in ovo threonine (Thr) supplementation on the ileal expression of glucose, peptide and amino acid transporters was assessed in Salmonella Enteritidis-challenged broiler chicks. At 17.5 days of incubation, fertile eggs were supplemented in the amniotic fluid with sterile saline or 3.

Expression of glucose transporters and morphometry in the intestine of Japanese quails after hatch.

The intestinal physiology and mechanisms involved in nutrient transport are not well established in quails (Coturnix coturnix japonica). The present study assessed the growth performance, morphological development, duodenal density and the expression of Sglt1 and Glut2 of female Japanese quails from 1 to 49 days of age. The three small intestine segments were sampled weekly from 1 to 49 days of age to evaluate villus height, crypt depth and villus: crypt ratio, and goblet cell counts.
