Abstract The objective of this study was to evaluate the modified hydrated sodium calcium aluminosilicate (HSCAS) adsorbent ability to reduce the toxicity of T-2 toxin in broilers. 96 one-day-old male broilers were randomly allocated to 4 experimental groups with 4 replicates of 6 birds each. The four groups 1–4 were received the basal diet (BD), BD plus 6.0 mg/kg T-2 toxin, BD plus 6.0 mg/kg T-2 toxin with 0.05% modified HSCAS adsorbent, BD plus 0.05% modified HSCAS adsorbent, respectively, for 2 weeks. The growth performance, nutrients digestibility, and digestive tract histopathology were analyzed. Compared with the control group, dietary supplementation of T-2 toxin decreased (P < 0.05) body weight gain, feed intake and feed conversion by 11.4–31.8% during d 1–7, d 8–14 and d 1–14. Dietary supplementation of T-2 toxin also decreased (P < 0.05) the apparent metabolic rate of crude protein, calcium, and total phosphorus by 14.9–16.1% during d 8–14. These alterations induced by T-2 toxin were mitigated or prevented (P < 0.05) by the supplementation of the modified HSCAS adsorbent. Meanwhile, dietary modified HSCAS adsorbent supplementation also prevented (P < 0.05) T-2 toxin-induced morphological changes and damage, such as severe degeneration and desquamation of the villous epithelial cells, congestion in intestinal lamina propria, and edema and thicken in the serosa with infiltration of numerous lymphoid cells, in the gizzard, duodenum, jejunum, and ileum of broilers. Notably, dietary supplementation of the modified HSCAS adsorbent alone did not affect (P > 0.05) any of those parameters. In conclusion, these findings indicate this novel HSCAS could be used as a promising adsorbent for protecting against T-2 toxin-induced toxicity in chicks (This work was supported in part by the National Key Research and Development Program of China, Projects 2018YFD0500601 and 2016YFD0501207).

Abstract The aim of the study was to analyse how per os application of hydrocolloids of silver nanoparticles (22 nm) and lipid-coated nanosilver hydrocolloids (5 nm) affect the microbiological status and morphology of the jejunum of broiler chickens and their growth performance. The experiment was conducted on 60 chickens. The first group was the control. The chickens in group II received a silver nanoparticle hydrocolloid (Ag-nano) at a dose of 5 mg/kg b.w./day. The chickens in group III received a lipid-coated nanosilver hydrocolloid (AgL-nano) at a dose of 5 mg/kg b.w./day. Samples of digesta were taken from the jejunum during dissection and the total numbers of fungi, aerobic bacteria and bacteria of the coli group were determined in the samples. Samples of the jejunum were also collected during dissection to determine the length of the villi and depth of the crypts. The silver nanoparticles had no effect on growth performance or the histological picture of the jejunum. An increase was noted in the total number of aerobic mesophilic bacteria and a decrease in the number of coli group bacteria, which are facultative anaerobes, which indicates that the nanosilver had a selective effect on the microflora of the digestive tract in the chickens.
