Obtained applying the typical solutions of different concentrations for each and every marker to quantify the concentrations from the experimental samples. The optical density values had been then measured at a wavelength of 450 nm employing a microplate reader (Biotek Instrument Inc., Winooski, VT, USA). two.eight. Statistical Analysis The collected data on bone characters had been analyzed employing the Statistic Package for Social Science computer software version 23.0 (SPSS 23.0; SPSS Inc., Chicago, IL, USA). The experimental unit of the present study was a single bird. Also, the data had been tested for normality utilizing the Kolmogorov-Smirnov test, as well as the information was located to become typically distributed. We performed a multivariate analysis of variance (ANOVA) utilizing a general linear model with repeated Cytoskeleton| measurements for body weight, serum markers related to Ca and P metabolism, and osteoblast and osteoclast activities determined by the within-subjects factors Time (18, 22, 25, and 29 WOA) and between-subjects variables Group (NK, DK, and FK) and Cage (C1 to C8). This statistical analysis model incorporated the effects of Time, Group, Cage, and their interaction, and consequently, it aided in determining whether or not bone character changes influence keel bone harm. In addition, the information on keel bone length and weight had been analyzed making use of one-way ANOVA based on Duncan’s post hoc multipleAnimals 2021, 11,six ofrange test. The results were presented as mean SEM, along with the differences were considered statistically important when p 0.05. 3. Benefits three.1. Measurement of Bodyweight The bodyweight of laying hens, with and with out keel bone harm, at every time point, are shown in Table two. The association between diverse sampling times (Time) and keel bone status (Group) and Cage had no substantial effect around the bodyweight in the laying hens (p 0.05). Having said that, the bodyweight of laying hens was affected by Group (p 0.05) and Time (p 0.01). Also, the bodyweight of laying hens from all groups drastically enhanced with age (p 0.05), while it was not different in between 25 and 29 WOA (p 0.05). The bodyweight with the laying hens inside the FK group was significantly lower than in the NK group (p 0.05). On the other hand, there was no important difference inside the bodyweight of the laying hens involving the NK and DK groups (p 0.05).Table two.

Measurement of Keel Bone Length and Weight There had been no considerable differences inside the length and weight of keel bones with the laying hens from three groups at 29 WOA (p 0.05), as shown in Table three.Table 3.
