Poultry is a light-sensitive animal and the light environment has an important influence on the growth and development of these animals. Previous studies have mainly focused on the effects of the light environment on various physiological indicators of poultry but seldom explored the light demand characteristics of broilers under free selection. This experiment mainly studied the light demand characteristics of broilers under a yellow LED light environment and the influence of different breeding densities [low-density (2.5 broilers/m 2 ), high-density (7.5 broilers/m 2 )] on the production performance and diet characteristics of broilers. Studies showed that the production performance indexes of low-density groups are higher than those of high-density groups. The feed and water consumption in the light area of the two experimental groups were significantly higher than those in the dark area, which means that the broilers showed a great preference for the light area. However, as the age of the broilers increased, the food and water consumption of the broilers decreased, indicating that broilers had a lower preference for light in the middle and late stages of growth. The statistical results for the residence frequency distribution characteristics showed that broiler chickens had different light requirements at different growth stages under the condition of active selection: 1) low-density breeding environment: 23.8L (light):0.2D (dark) for chicks and 22.3L:1.7D for adult broilers; 2) high-density breeding environment: 22.6L:1.4D for chicks and 15.

“…Calik et al reported nearly 2,500 g of Cobb500 broilers' BW in control and treatment groups on the 42nd day of their experiment ( 50 ). The mean weight gain of Cobb500 broilers on the 42nd day of the Manfio et al study was 2,828.6–2,806.9 g depending on the experiment condition ( 51 ). Castro et al reported BW values in the negative control group on the 42nd day that are similar to our data (2,082 g).…”

Probiotics are known for their beneficial effects on poultry health and wellbeing. One promising strategy for discovering Bacillus probiotics is selecting strains from the microbiota of healthy chickens and subsequent screening for potential biological activity. In this study, we focused on three probiotic strains isolated from the gastrointestinal tract of chickens bred in different housing types. In addition to the previously reported poultry probiotic Bacillus subtilis KATMIRA1933, three strains with antimutagenic and antioxidant properties Bacillus subtilis KB16, Bacillus subtilis KB41, and Bacillus amyloliquefaciens KB54, were investigated. Their potential effects on broiler health, growth performance, and the immune system were evaluated in vivo. Two hundred newly hatched Cobb500 broiler chickens were randomly divided into five groups (n = 40). Four groups received a standard diet supplemented with the studied bacilli for 42 days, and one group with no supplements was used as a control. Our data showed that all probiotics except Bacillus subtilis KATMIRA1933 colonized the intestines. Treatment with Bacillus subtilis KB54 showed a significant improvement in growth performance compared to other treated groups. When Bacillus subtilis KB41 and Bacillus amyloliquefaciens KB54 were applied, the most significant immune modulation was noticed through the promotion of IL-6 and IL-10. We concluded that Bacillus subtilis KB54 supplementation had the largest positive impact on broilers' health and growth performance.

Environmental changes have an impact on agriculture, especially the production of poultry. These changes have caused grave concerns that will negatively affect the health and productivity of chickens. We must consider illumination, density, and dietary aspects when determining the optimal environmental conditions for poultry rearing and output. Each of these variables influences the performance and behavior of birds uniquely. A crucial aspect of evaluating animal well-being is that it understands animal behavior. Artificial lighting has been widely investigated in poultry production over the last fifty years to enhance muscle gain and egg production while preserving an effective feed conversion ratio, bird health, and well-being. Yet, researchers and breeders still disagree over the ideal light quality and quantity, density, and feeding levels for poultry farming, particularly for chickens. This evaluation, therefore, covered the most up-to-date practical methods for enhancing illumination, density, and feeding-related aspects of poultry behavior, health, and production.
