“…On the other hand, the increase of Ca absorption can promote the skeleton mineralization ( Zhang et al., 2006 ). When the serum Ca concentration decreases, Ca is mobilized from the bones to maintain the physiological blood level ( Amoroso et al., 2013 ). Therefore, YOL may be useful for the skeleton growth and development of layer chickens by increasing the serum Ca concentrations during the brooding and rearing periods.…”

The behavior, growth and development, and production performance of poultry are affected by the light environment. The influence of light results from a combination of light sources, light intensity, light color, and the photoperiod regimen. With light-emitting diode ( LED ) lamps applied in poultry housing systems, specific light colors are desired for each time period for layer chickens. The objective of this study was to investigate the effects of a 2-phase mixed color lighting program (phase 1: blue-green, 1 D–13 wk; phase 2: yellow-orange, 14–20 wk) using LED lights on the blood parameters, skeletal development parameters, and sexual development parameters of caged layer chickens during their brooding and rearing periods. Fifty-two chickens were raised from 1 D to 20 wk of age in each of the 4 treatment groups with 3 replicates, with white (400–700 nm) light at phase 1 and phase 2 ( WL treatment as the control); blue–green (435–565 nm) light at phase 1 followed by yellow–orange (565–630 nm) light at phase 2 ( BG-YOL treatment); yellow–orange LED (565–630 nm) light at phase 1 and phase 2 ( YOL treatment); and blue–green (435–565 nm) light at phase 1 and phase 2 ( BGL treatment). The results showed that the serum Ig concentrations of the layer chickens in the BG-YOL treatment and BGL treatment were higher than those in the WL treatment at 13 wk of age ( P < 0.05). At the age of 20 wk, the serum glucose concentration levels of the pullets after the WL and BGL treatments were lower than those after the YOL treatment ( P < 0.05). Compared with the WL treatment, the YOL treatment significantly increased the bone mineral density of the layer chickens ( P < 0.05), and BG-YOL treatment promoted the development of the sexual organs (oviducts and ovaries) of the laying hens at the age of 20 wk ( P < 0.05). For the 50% egg production age, the YOL treatment was earlier than the other 3 treatments. This study demonstrated that appropriately staged spectral control using LED lights could have positive effects on the immune performance, bone development, and production performance of caged layer chickens during their brooding and rearing periods.

“…Bone growth and mineralization were less pronounced during the finisher phase, and this explains the lack of statistical difference among certain variables. The data demonstrated adequate bone development and integrity without disorders and the muscular, ligamentous and tendinous development was stabilized, parameters that depend on the bone state, which stabilizes as the birds grow (Amoroso et al, 2013).…”

The objective was to evaluate the effect of diets containing various levels of phytate and phytase on broilers from 1 to 42 days old. The treatments consisted of a combination of diets containing high (HP), medium (MP) and low (LP) phytate with positive control diet (PC) and a negative control diet (NC) that was similar to the PC in energy and protein but with less calcium and phosphorus. Three additional diets, based on the NC were supplemented with 500, 1000, or 1500 FTU kg-1 of phytase. Broilers that received the NC diet exhibited the lowest weight gain (WG), whereas those supplemented with 1000 FTU kg-1 obtained 2.84% higher WG compared with PC. Broilers that received NC had the lowest breaking strength and dry matter. Birds fed HP diets that received NC and NC + 500 FTU kg-1 had a higher concentration of serum Ca and P than birds fed LP diets. Broilers fed the NC and NC + 500 and 1000 FTU kg−1 had lower tibia Ca levels compared with birds fed the PC. Broilers fed HP diets had higher tibia Ca content than MP. Phytase supplementation had a positive response in diets with reduced Ca and P. Based on regression analysis the optimum inclusion of phytase to improve broiler performance parameters was calculated as 952 FTU kg-1.

“…BMD is a biophysical parameter with experimental and clinical significance; it is an important indicator of bone quality and can reflect bone development ( Riczu et al, 2004 ; Amoroso et al, 2013 ), and it is positively correlated with bone strength ( Mccoy et al, 1996 ). The research results show that white LED light can improve bone mineral density, probably because white light belongs to full-wavelength light, and the long-wavelength light part contains higher energy, which can directly pass through the skull of the layer and act on the hypothalamus, synthesizing estradiol (E2) that is essential for stimulating the switch from structural bone to medullary bone deposition of calcium in bones, such as the tibia ( Baxter et al, 2014 ; Bédécarrats, 2015 ; Bain et al, 2016 ; Takeshima et al, 2019 ).…”
