Evaluation of dried tomato pomace as a non‐conventional feed: Its effect on growth, nutrients digestibility, digestive enzyme, blood chemistry and intestinal microbiota of growing quails

Abstract

This work evaluated the effect of sun-dried tomato waste (SDTP) on growth, carcasses, digestibility of nutrients, digestive enzymes, blood chemistry and intestinal microbiota of 250 one-week-old growing Japanese quail. The birds were randomly distributed into 5 equal groups. Group 1 was fed on the basal diet (BD) (control), Groups 2, 3, 4 and 5 were fed on the BD containing 3, 6, 9 and 12% SDTP respectively. SDTP significantly improved the body weights and gains at 3 weeks of age compared with control, and the 6% SDTP level seems to be the optimal level used throughout the first 3-5 weeks of age. With 6, 9 or 12% SDTP, the percentages of liver and giblets and the meat percentages of moisture and crude protein were improved significantly relative to control or 3%. In quail diets, the percentage of ether extract was reduced with increasing the SDTP. The studied levels of SDTP did not significantly change the digestibility of DM, OM, CP or NFE. The highest levels of amylase and lipase enzymes were recorded in the 6% SDTP, opposite to control. SDTP at 9 and 12% significantly decreased the total cholesterol than all other treatments. The highest and the lowest HDL levels were shown in 12 and 9% SDTP respectively. The 12% SDTP showed the highest SOD, TAC, IgM, IgG and Complement 3 values among all groups. The different levels of SDTP significantly reduced the MDA content than control. The highest caecal E. coli and Salmonella spp counts were found in control and 6% inclusion level followed by 9% and finally 3 and 12% SDTP. In conclusion, dietary inclusion of SDTP can enhance the growth and health status of growing quails via improving the nutrient digestibility, digestive enzymes, and blood chemistry and reducing the intestinal pathogens.

The influence of bacterial selenium nanoparticles biosynthesized by Bacillus subtilus DA20 on blood constituents, growth performance, carcass traits, and gut microbiota of broiler chickens

“…For extraction of plasma from the blood, blood cells removed by centrifugation (at 2,000 × g for 15 min at 4°C), and then kept (at −20°C) for pending investigation. Blood plasma metabolites, including total protein ( TP ), albumin ( ALB ), globulins ( GL ), A/G ration, alanine aminotransferase ( ALT ), aspartate aminotransferase ( AST ), urea, creatinine, total bilirubin ( TB ), direct bilirubin ( DB ), glucose, and triglycerides ( TG ) were assessed by spectrophotometric method conferring to the manufacturer's ( Alagawany et al, 2022 ).…”

Ameliorative avian gut environment and bird productivity through the application of safe antibiotics alternatives: a comprehensive review

“…Processed phytogenic compounds, essential oils, and oleoresins all differ in their effectiveness depending on the type of compound used, the dosage, and the method of preparation, as well as external factors like food, and heredity ( Gadde et al, 2017 ; Alagawany et al, 2022 ). Essential oils are volatile chemicals extracted from plants, and their influence and efficacy have been the subject of numerous investigations ( Abd El-Hack et al, 2022f ).…”
