Abstract
Rice is a seed derived from the grass species Oryza sativa or Oryza glaberrima. This paper investigates the several facets of rice, including its nutritional worth, cultural relevance, methods of farming, and worldwide significance. Rice is a promising grain that is reasonably priced and may be effectively added to chicken rations. Because rice is more readily available than corn and has comparable protein and metabolizable energy levels. The current study aimed to see the effect of replacing corn with cheap rice and to see its effect on broiler chickens small intestine by measurement intestine villi high , villi width , villi area, crypt depth and muscular thickness ratio A total of one hundred sixty (160) at one-day-old unsexed chicks of the Rose 308 breed were purchased from local hatchery. The birds were fed on basil diet for two week (14 days), at day 15 of the experiment the bird were randomly divided into 4 groups each group contain a forty (40) birds, and each group was subdivided into two groups, each group contain 20 birds, in a sector design. The control group (T) was fed on the basil diet, while the birds in group T1, T2, and T3 were fed 10%, 20%, and 30% of the rice were given by replacing corn in the food ration. The current study showed that there is a significant (P≤ 0.05) increase in the duodenum, jejunum and ilium villi length (mm). Villi width (mm) villi area (mm)2 crypt depth in the basil diet group as compeer with other groups. the current study conclude that as the amount of rice provided to broiler chickens increases leads to a decrease in the length, width, and crept depth of the villi.
