Mineral Source and Vitamin Level in Broiler Diets: Effects on Performance, Yield, and Meat Quality

Abstract

The purpose of this trial was to supplement commercial broiler diets with optimum vitamin programs and higher availability of mineral sources, and to evaluate the effect on performance, yield and meat quality of broilers. The study used 1800 male broiler chicks randomly distributed in a 2 x 2 factorial design (vitamin programs -optimum and commercial vs. mineral sources -inorganic (sulfates) and carbo-aminophospho-chelate (CAPC)). Supplementation associating optimum vitamin levels and mineral source CAPC resulted in better feed conversion and higher carcass weight at 42 days of age (p<0.05). Supplementation of diets with optimum vitamin levels resulted in higher absolute and relative breast weight, lower abdominal fat deposition, and reduction (p<0.05) of broiler breast water loss by dripping. Supplementation with CAPC minerals resulted in higher breast weight, lower abdominal fat deposition, less elastic muscle tissue, that is, a higher level of tenderness resulting in less resistance of muscle fibers and skin with higher tear strength than the skin of birds fed inorganic sources. Associating optimum vitamin programs and CAPC mineral source resulted in lower (p<0.05) lipid peroxidation levels in thighs and drumsticks after 10 and 40 days freezing. No difference (p>0.05) was found in the association of vitamin programs and mineral sources on the occurrence of white striping and dorsal myopathy. Supplementing the diets with optimized vitamin programs associated with a more bioavailable mineral source resulted in a positive contribution to the meat quality of broilers.

Effects of dietary copper and zinc hydroxychloride supplementation on bone development, skin quality and hematological parameters of broilers chickens

“…The birds were slaughtered at 42 days of age. The skin samples (3 × 3 × 3 cm) were subjected to a flexion test at a constant strain rate for a viscoelastic material, using a texturometer (Model TA‐XT2i; Stable Mycro Systems LTDA) at speed of 1 mm/s, 10 g shot and 15 mm tension (Ribeiro et al, 2020).…”

From Metabolism to Vitality: Uncovering Riboflavin’s Importance in Poultry Nutrition

“…In broiler chickens, for instance, riboflavin needs are influenced by their rapid growth during the fattening phase [25]. This phase, characterized by rapid muscle and skeletal development, necessitates increased riboflavin intake, along with other essential vitamins, to support energy metabolism and tissue repair [148]. Conversely, when considering laying hens during their peak egg production phase, distinct vitamin B 2 requirements emerge [11,56].…”
