Tezisda ichimlik suvi orqali berilgan xitozan va quruq sut zardobi majmuasining Kobb-500 broyler jo‘jalaridagi maqbul sutkalik miqdori fiziologik, zootexnik va iqtisodiy mezonlar majmui asosida baholandi. Jami 100 bosh jo‘ja nazorat hamda 40, 60 va 80 mg/jo‘ja/kun majmua olgan uch tajriba guruhiga ajratildi. 60 mg/jo‘ja/kun variantida azot retensiyasi, yakuniy tirik vazn, yem konversiyasi, tana go‘shti chiqimi va rentabellikning eng muvozanatli natijalari qayd etildi. 80 mg miqdor ayrim ko‘rsatkichlarda yuqori qiymat bergan bo‘lsa-da, umumiy ishlab chiqarish va iqtisodiy bahoda barqaror qo‘shimcha ustunlik ta’minlamadi. Natijalar maqbul miqdorni birgina ko‘rsatkich emas, o‘zaro bog‘langan mezonlar tizimi orqali tanlash zarurligini ko‘rsatadi.
