A total of 270 one-day old Cobb 500 chicks were equally divided into three groups (90 chicks\/group). The first control group (G1) was fed on the basal diets without any yucca supplementation. The 2nd and 3rd groups (G2 and G3) were fed on basal diets with Yucca Plus liquid\u00ae, at an 8 h\/day supplementation rate of 0.5, and 1 mL\/L to drinking water, respectively. The chicks that received yucca showed significant decreases in litter nitrogen content, when compared to controls. The chicks that received liquid yucca had reduced counts of total bacteria (TBC) (p &lt; 0.05), Escherichia coli, and a non-significant increase in the number of lactic acid producing bacteria. They also showed increased activity of antioxidant enzymes, increased levels of immunoglobulins M and G, and decreased levels of lipid peroxidation biomarkers, without a harmful effect on liver and kidney function. The chicks that received yucca showed a better feed conversion ratio. In conclusion, the use of natural additives is necessary to decrease nitrogen losses, feed cost, and environmental pollution; without adverse impacts on animal performance. Liquid supplementation of saponins is valuable for the performance, gut health, and welfare of broiler chickens.<\/jats:p>","DOI":"10.3390\/ani9121097","type":"journal-article","created":{"date-parts":[[2019,12,9]],"date-time":"2019-12-09T05:54:51Z","timestamp":1575870891000},"page":"1097","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Effects of Liquid Yucca Supplementation on Nitrogen Excretion, Intestinal Bacteria, Biochemical and Performance Parameters in Broilers"],"prefix":"10.3390","volume":"9","author":[{"given":"Mousa","family":"Ayoub","sequence":"first","affiliation":[{"name":"Department of Animal Hygiene and Zoonoses, Faculty of Veterinary Medicine Damanhour University, Damanhour 22511, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4433-0039","authenticated-orcid":false,"given":"Hamada","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Veterinary Clinical Nutrition, Faculty of Veterinary Medicine, Damanhour University, Damanhour 22511, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kadry","family":"Sadek","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Veterinary Medicine, Damanhour University, Damanhour 22511, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8020-0971","authenticated-orcid":false,"given":"Mahmoud","family":"Alagawany","sequence":"additional","affiliation":[{"name":"Poultry Department, Faculty of Agriculture, Zagazig University, Zagazig 44511, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2831-8534","authenticated-orcid":false,"given":"Mohamed","family":"Abd El-Hack","sequence":"additional","affiliation":[{"name":"Poultry Department, Faculty of Agriculture, Zagazig University, Zagazig 44511, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Othman","sequence":"additional","affiliation":[{"name":"Biology Department, Collegeof Science, Princess Nourah bint Abdulrahman University, 11671, BO.
