| Sumario: | ABSTRACT: The current trends in the production of broiler chickens indicate the need to look for natural solutions that affect the efficiency of production and the quality of meat. The aim of the study was to evaluate the growth performance and quality of broiler chicken meat with the addition of halloysite in feed and litter. Two hundred Ross 308 were used and divided into 2 groups (10 replicates each). The control group (C) did not have any additive, while in the experimental group (H) 0.5% halloysite was used in feed and 0.500 kg/m2 in peat litter. The production results and litter traits were checked. The presence of footpad dermatitis (FPD) was assessed. After 42 d, 20 birds were randomly selected and slaughtered. Dissection was performed. The slaughter yield and the percentage of carcass elements were calculated, including offal. Breast and leg muscles were analysed qualitatively (pH, colour, water-holding capacity, drip loss, chemical composition). In group H there were no changes to FPD, and in group C there were 6 cases of benign lesions and 1 with severe damage and scabs on the soles of the feet. Significantly higher preslaughter body weight was shown, as well as carcass and wings weight in group H. The H group had a higher pH24 than the C group, as well as higher protein and water content, and lower intramuscular fat and salt, both in the breast and leg muscles. No significant differences were found in growth performance carcass, meat’ colour or water-holding capacity features. The litter with halloysite was characterized by a lower pH but without statistical confirmation. Addition of halloysite to feed and litter reduced the occurrence of skin lesions and had a positive effect on higher protein content and lower intramuscular fat in the breast and leg muscles. This demonstrates the potential for the practical use of halloysite in the production of broiler chickens, both as a feed and peat litter additive. |
