Effects of organic macro and trace minerals in fast and slower growing broiler breeders’ diet on offspring growth performance and tibia characteristics

Abstract

This study was designed to evaluate effects of source of macro and trace minerals (inorganic vs. organic) in fast and slower growing broiler breeders’ diets on egg and hatchling mineral content and on offspring tibia morphological, biophysical, and mechanical characteristics. After 10 wk feeding the breeders (at 30 wk of age), eggs were collected and incubated. Eggs and hatchlings were analysed on mineral content. Male chickens were assigned to 32 pens with 12 chickens per pen. At approximately 1,700 and 2,600 gram BW, three chickens per pen were slaughtered. Tibia characteristics were determined. Organic minerals in the broiler breeder diet resulted in higher Fe and Se concentration in the egg and in higher Se concentration in the hatchling. Despite effects of mineral source on mineral concentration in the eggs and hatchlings were limited, organic minerals in the slower-growing broiler breeder diet resulted in higher offspring BW (d 42, Δ = 115 g; P = 0.03) and advanced tibia development (higher thickness (∆ = 0.38 cm; P < 0.001), osseous volume (∆ = 5.1 cm 3 ; P = 0.01), and mineral density (Δ = 0.13 g/cm 3 ; P = 0.03) at 2,600 g BW), but this was not observed in fast-growing chickens. This suggests that 1) the difference in feed intake of the breeders between strains might affect offspring performance, which might indicate that current slower-growing breeder diets might be suboptimal in minerals or that transgenerational mineral availability in slower growing chickens appears to be more effective on bone development, which might be related to time available for bone development. 2) transgenerational mineral availability in offspring appears to play a role via other mechanisms than via absolute mineral concentrations.

Soybean vs. Pea Bean in the Diet of Medium-Growing Broiler Chickens Raised under Semi-Intensive Conditions of Inner Mediterranean Areas: Growth Performance and Environmental Impact

“…Furthermore, focusing on well-being and housing conditions, chicken meat production is more oriented towards less intensive systems, for which medium- and slow-growing broiler strains have been recommended [ 7 ]. In fact, medium- and slow-growing chickens are more suitable for alternative production systems for their higher vitality, disease resistance, and adaptability to outdoor conditions than fast-growing chickens [ 8 , 9 , 10 , 11 ].…”

Tibia properties in broilers raised on their own commercial diets with different growth rates and sex during a 10‐week rearing period

“…( 2015 ) showed that genetic factors determining faster growth also led to heavier, longer and wider leg bones in broilers. However, some researchers (Güz et al., 2022 ; van der Eijk et al., 2022 ) showed that slow‐growing broilers have better tibia morphological characteristics compared to fast‐growing broilers at the same body weight. This discrepancy among studies is likely explained by sampling at different ages and body weights.…”

Oligomeric proanthocyanidins ameliorates osteoclastogenesis through reducing OPG/RANKL ratio in chicken's embryos

“…In the present study, 100 mg/kg OPC increased the content of Ca and P of femur and tibia, but the ratio of Ca and P remained unchanged. Furthermore, trace minerals also plays a crucial role in the bone development of poultry ( M'Sadeq et al, 2018 ; Güz et al, 2022 ). Fe, Mg, Cu, and Mn plays a vital role in the growth and development of poultry, and cannot be underestimated in the formation of bone tissue and maintenance of bone health ( Sun et al, 2015 ; Echeverry et al, 2016 ; Byrne and Murphy, 2022 ).…”
