Effect of Different Levels of Citrus Waste (Kinnow sp.) on Duodenal Morphology of Broiler Birds Without and With Cocktail of Enzymes


DOI:Coming soon...

Abstract:

The study was carried out to determine the effect of different levels of citrus waste (Kinnow sp.) as replacement of whole ration on intestinal morphology in broilers. The experiment consisted of 256 meat type birds. The day old birds were distributed into 8 groups and each group was replicated four times. Eight dietary treatments included Control (T1), positive control (T5) and Citrus waste was supplemented at 2.5, 5.0 and 7.5 percent level in diet T2 to diet T4 and citrus waste with cocktail of enzymes was added from diet T6 to diet T8 during starter (0-14 days), grower (15-21 days) and finisher (22-42 days of age) phases. The birds of equal body weight were slaughtered on 42nd day. After thorough examination sections of duodenum were collected and processed. Images were taken to measure villi height and crypt depth. Study showed that the inclusion of citrus waste up to 5% level improved (P<0.05) duodenal morphology with higher villi length and crypt depth. More number of polymorphonuclear cells was observed at places in mucosa suggesting better immunomodulatory effect due to inclusion of citrus waste in the diet. However, supplementation of enzyme (100 g/q) didn’t showed any significant (P<0.05) difference between the groups. It can be concluded that supplementation of citrus waste decreased the villi height and crypt depth at higher citrus waste inclusion level.
