growth performance, tibia characteristics, immune response and blood metabolites of broiler chickens fed diets containing citrus brown snail (caucasotachea lencoranea) powder as a source of calcium

objective: an experiment was conducted to investigate the effects of citrus brown snail powder as a source of calcium on growth performance, tibia characteristics, immune response and blood metabolites in broiler chickens.  methods: one hundred and eighty 1-day old chicks were randomly distributed into four treatments, each of which had three replicates. each replicate contains 15 chicks. the treatments were included four inclusion rates of citrus brown snail powder (0, 0.5, 1 and 1.5%) in diets.  results: the results showed that diets supplemented with 2% snail powder improved feed conversion ratio of broilers at 42 days of age (p
