“… Jing et al (2018) observed the content of Ca and P, while Newman and Leeson (1998) only the content of Ca. Many studies previously confirmed the essential role of Ca, P, and Mg for bone quality across the animal species, from rats ( Takahara et al, 2000 ), through rabbits ( Krunt et al, 2021 ) to poultry ( Shastak and Rodehutscord, 2015 ). In the present study, the effect of genotype resulted in significant differences of Ca, P, and Mg content in tibia and femur bones.…”

“…Regarding the elemental composition of bones, scientific studies usually focus on nutrition ( Olgun and Aygun, 2016 ) or the housing system in connection with movement ( Krunt et al 2021 ). However, our study analyzed the elemental composition of bones from a different perspective and focused on the effect of genotype.…”

“…In general, Ca and P are mutually influenced, and Mg is closely connected to them, while Mg is an antagonist to Ca ( Shastak and Rodehutscord, 2015 ). Krunt et al (2021) , who studied Ca, P, and Mg content in the tibia and femur bones of rabbits in various housing systems, highlighted the importance of Mg for bone quality, specifically for fracture toughness, and concluded that Mg could be a key player in the determination of bone fracture toughness. Considering the element Mg, it is essential for the metabolism of cells and bone development ( Shastak and Rodehutscord, 2015 ).…”

“…The fracture toughness was probably also affected by the same factor, which was mentioned in the previous statement. It was higher in drakes due to greater width or weight, which should indicate the higher content of elements that affected bone strength [33].…”

The study was conducted during the summer season (June–August 2020). Two hundred sixty-four 5-week-old sexed Muscovy ducklings were randomly divided into four equal experimental groups by housing system and by gender. Each group had three replicates (22 birds/replicate) in a randomized design experiment. Regarding the hematological traits, the volume of leukocytes was higher in the D group (by 0.34 × 109/L; p < 0.05) than in the S group. Furthermore, body temperature was found to be higher in ducks (by 0.84 °C; p < 0.05) and in the D group (by 0.5 °C; p < 0.05) in comparison with drakes and birds from the S group. Considering relative brain weight, drakes had higher values than ducks (by 0.56 g; p < 0.05), and birds from the S group also manifested higher values (by 0.78 g; p < 0.05). In terms of bone quality, there were no differences in studied parameters of tibia and femur bones regarding housing systems. The results provide valuable evidence of differences in the fattening of intensively bred Muscovy ducks within the housing system but also regarding gender.

“…The change in Mg level with age was similar to that of the P level. Krunt et al (2021) stated that Mg in the tibia and femur bones of rabbits was an effective mineral in bone fracture resistance. The potassium amount per unit body weight was high in fast-growing broilers at week 1 (p < 0.001) and this situation was reversed from the week 4 (p < 0.05).…”

BackgroundGenetic selection applied to broilers results in fast growth and an increase in meat yield. However, this situation causes welfare problems in broilers.ObjectivesThe aim of this study is to determine the weekly changes in the tibia characteristics in broilers raised on their own commercial diets.MethodsIn the study, 168 (84 female and 84 male) slow‐growing (Hubbard‐Isa Red JA) and 168 (84 female and 84 male) fast‐growing (Ross‐308) day‐old broiler chicks were used. Six broilers from each genotype and sex group were weighed weekly and slaughtered to determine the tibia properties during the 10‐week fattening period.ResultsFast‐growing broilers had higher tibia weight and longer length, diaphysis diameter and medullary canal diameter than those of slow‐growing broilers at the same age. In fast‐growing genotypes, the cortical index was low only in the 2nd week, and Robusticity and Seedor indices were observed to be better throughout the whole fattening. The ash content of the total tibia in the fast‐growing broilers was higher in all of the examined weeks except the 4th week and the 9th week of fattening than that in the slow‐growing broilers. Although the amount of ash per unit body weight in the 1st week of fattening was higher in fast‐growing broilers, this situation reversed after the 4th week. The level of all minerals examined in total tibia weight is high in fast‐growing broilers, and they differed according to the fattening period.ConclusionsWhen comparing tibia characteristics of two different genotypes fed their own commercial diets, the tibia structure was found to be stronger in fast‐growing broilers compared to other genotypes at the same age, but slow‐growing broilers were more prominent in terms of body weight. It was observed that the mineral density was higher in male broilers, except in the 1st week.
