Effects of Physical Size of Clinoptilolite on Growth Performance, Serum Biochemical Parameters and Litter Quality of Broiler Chickens in the Growing Phase

摘要: A total of 448 Ross 308 male broiler chickens were assigned to seven treatments with four replicates, each containing 16 chicks. The birds reared from d 21 42 and effects physical sizes (ad libitum by a basal commercial diet 3050 Kcal/Kg ME 19.06% CP/Kg d. which received clinoptilolite (1.5% particle size 0.4-0.8 mm) showed significant increase in body weight gain compared the control group receiving no  (P<0.05). Adding caused improvement feed conversion ratio days 21-28, 28-35, 35-42 21-42 Broilers fed 1.5% 0.4- 0.8 mm had lower other groups. highest level blood glucose, protein albumin found mm, while lowest obtained groups litter moisture was observed 3% 1-2 mm. Therefore, it can be concluded that supplementation has positive on performance broilers.
