The treatments T1,T2,T3,T4 and T5 were injected with normal saline (0.5 ml), amino acids (Glycine-3.22 mg + Proline-3.24 mg), amino acids (Lysine-5.16 mg + Arginine-5.04 mg + Glutamine-12.10 mg), amino acids in T2 with nano form of selenium (0.3 μg) and amino acids in T3 with nano form of selenium (0.3 μg), respectively in ovo on 18th day of incubation. Intestinal histomorphology revealed that supplementation of amino acids in combination with nano form of selenium influenced villus length and width of duodenum, jejenum and ileum. Based It was concluded that in ovo supplementation of amino acids and nano selenium improves (P<0.01) small intestinal villus length and duodenal villus width in broilers in comparison to control treatment.enVeterinary ScienceArticle
