The Effect of Depth of Rice Hulls Litter on Fattening Performance, Foot Pad Dermatitis, Meat Quality Characteristics of Broiler Chicken
Öz
This study was carried out to determine the effect of rice hulls used as litter in two different thicknesses (5 and 10 cm) on fattening performance, mortality rate, foot pad lesions, meat quality and meat color characteristics of Ross 308 chickens. Rice hulls of 5 cm (T5) and 10 cm (T10) thickness were laid on the coops that were similar in size and design. Fattening performance, FCR (feed conversion ratio), mortality rate, foot pad lesions, meat quality, and meat color characteristics were determined in three consecutive fattening periods. It was determined that the feed conversion ratios were 1.748 and 1.577 in the T5 and T10 groups, respectively, and the difference was significant (P<0.05). There was no statistically significant difference between the two litter thickness groups in mortality rates, foot pad lesions of the chickens, meat quality characteristics and, meat color characteristics (P>0.05). On the other hand, it was determined that the difference between foot pad lesion scores within the litter thickness groups was significant (P<0.001). As a result, although it is considered an advantage that rice hulls are cheaper than other litter varieties, it is a disadvantage that the lesion rates at Score 3 and 4 levels are high. Since there is no significant difference between the T5 and T10 groups without FCR. Therefore, it may be economically beneficial to use 5 cm thick as a substrate instead of 10 cm.
