“…Similarly, adding lactulose in ration caused increase in phosphorus level in rabbit [ 56 ]. Adding of lactulose to broiler diet led to an increase in the serum level of urea, glucose, phosphorus, ALT, total protein and albumin [ 26 ].…”

“…In broiler chicken, BWG was increased by increasing the amount of lactulose in the diet from zero to 0.5% [ 25 ]. Additionally, lactulose-containing feed additives have a positive effect on the biochemical composition of blood, metabolic processes and the natural resistance in broiler [ 26 ].…”

“…There are limited reports about using lactulose in broiler chickens [ 20 , 25 , 26 ] have been mentioned, however, the effect of lactulose on laying performance, egg quality and genes related to reproduction and immunity have not been reported. In the present study, we evaluated the effects of lactulose in the form of Vetelact on body weight, egg production, egg quality, blood biochemical parameters and expression of genes associated with reproductive performance in laying hens.…”

Background The rising popularity of eggs as an alternative source of protein to meat has led to significant increase in egg consumption over the past decade. To meet the increasing demand for eggs, poultry farmers have used antibiotics to treat infections and, to some extent, promote growth and egg production in raising layer. However, the emergence and global spread of antibiotic resistant bacteria has now necessitated antibiotic-free poultry farming. As alternatives to antibiotics, prebiotics are feed additives that can be used to improve the growth and laying performance of poultry which positively impacts their performance and general health. In this study we evaluated the effect of lactulose, formulated as Vetelact, on body weight, egg production, egg quality, blood biochemical parameters and expression of genes associated with reproductive performance in laying hens. Results Vetelact supplementation improved egg weight, egg production as well as egg quality. Following Vetalact supplementation, the levels of total bilirubin, total protein, globulin and phosphorus were increased, while the activities of alkaline phosphatase and lipase enzymes were increased compared to control. Vetelact at 0.10 ml/kg body weight upregulated OCX-36, OVAL, CALB1, OC-116, OCX-32 and IL8 transcripts while downregulating the transcription of Gal-10, PENK and AvBD9. At this optimal inclusion rate of Vetalect, histomorphologic analyses of intestinal tissue showed increased villi length with more goblet cell distribution and obvious mucus covering a surface, increase in the depth of intestinal crypts produce digestive enzymes, as well as more developed muscle layer that promote improved nutrient absorption. Conclusion Vetelact at a dose of 0.10 ml/ kg body weight was effective in improving productive performance of laying hens. Adding lactulose (0.10 ml/ kg body weight) to layer diet is recommended to promote growth and improve egg laying performance in antibiotics-free poultry production.
