Effects of different broiler flooring systems on surface temperature, air quality and carcass characters of broilers

Abstract

The present study investigated the use of perforated plastic floors with different heights in the broiler performance, surface temperature, air quality, and carcass characters of broilers. Three hundred sixty-seven day-old unsexed chicks randomly divided into 4 groups: control reared on sawdust litter in others used, plastic floors with different heights (5, 10 and 15) cm, for 2nd, 3rd and 4th treatment respectively. The first treatment (sawdust) showed significantly (P < 0.05) increase in body surface temperature, as compared to the plastic floors system treatments, and the three plastic floor treatments affected air quality, with less concentrations of ammonia and carbon dioxide compared to the sawdust. The results showed significant differences (P < 0.05) in the live relative weight, where the treatments T2, T3 and T4 were increase at the age of 35 days compared to the sawdust treatment. We suggested the perforated plastic floors could be a good alternative to promote a better quality environment and superior production rates with improved surface temperature.

The Type of Floor and its Impact on the Growth, Physiological and Performance of Broilers

“…The perforated floor wire floor has a positive effect on the health and behavior of domestic birds, which is evidenced by indicators of welfare without a decrease in indicators of productive performance [15]. The results showed that raising broiler chickens on the wire floor did not record significant differences in most of the productive traits at the age of 21 and 38 days , We agree with Al-Nasiri [7,8] as well as the relative weight of abdominal and liver fat, The results did not agree with [4]. nor did we find differences in the relative weight of the Bursa of fabricius, Thymus gland [4].…”

“…The effect of the floor type on the on serum Antioxidant activity. The results of Table (8) shows that there are no significant differences between groups in thyroid hormones, melatonin hormone and growth hormone in the serum of broiler chickens. Table 8.…”

“…The effect of the floor type on the biochemical parameters of the broiler. The results of Table (7) shows that wire ground broilers led to an improvement in antioxidants, as the G2 recorded a significant increase in the level of GSH compared to the G1. Table 7.…”

“…nor did we find differences in the relative weight of the Bursa of fabricius, Thymus gland [4]. Body temperature is an important indicator for domestic birds, as it directly affects their vital functions, as body temperature directly affects internal physiological processes, the rate of metabolic processes, and the metabolic rate is directly proportional to the release of heat energy during food digestion [16], the results in showed that the wire floor had a significant effect in reducing the average total temperature of the surface part of the broiler's body, and the reason may be due to the role of the wire floor in providing the appropriate environment for broiler broilers, where birds are separated about its waste and improving air quality and the quality of thermal insulation [8]. That footpad dermatitis is a form of contact dermatitis associated with litter quality, which in turn is influenced by poultry house management conditions, including temperature and ventilation [17].…”

“…As it provides suitable environmental conditions for birds, such as low humidity and emission of gases, especially ammonia, and achieves bird welfare [6]. The reason for this improvement may be due to providing the appropriate environment for the growth of broilers, where birds are separated from their droppings, and improving the air quality and the quality of thermal insulation [7,8].…”
