“…Few previous studies have focused on the influence of dietary Ca and NPP on carcass traits. Smith and Taylor (1961) found that there was no significant difference in the percentage of grade A or grade B carcasses from broilers fed with 2 Ca levels. Dressing percentage, percentage of breast yield, and abdominal fat were also similar when Ross 308 broilers were fed with different concentrations of Ca and NPP ( Swiatkiewicz et al., 2011 ).…”

“…In the present study, the dietary Ca level had significant influence on the ADFI of yellow-feathered broilers, and FBW, ADG, and ADFI were significantly affected by the dietary NPP level. Half a century ago, Smith and Taylor (1961) had proved that broiler chicks on a lower Ca (0.73%) diet consumed less feed than did birds on a higher Ca (1.3%) diet. Research on Ross 308 broilers showed that the Ca level promoted differences in intake and FBW, and added P increased growth performance ( Hamdi et al., 2015 ).…”

This experiment investigated the effect and interaction of dietary calcium ( Ca ) and nonphytate phosphorus ( NPP ) on growth performance, tibial characteristics, carcass traits, and meat quality for slow-growing yellow-feathered broilers during 56 to 84 d of age. A 3 × 3 factorial arrangement was used, and 720 56-day-old broilers were randomly divided into 9 groups and fed with diets containing different levels of Ca (0.70, 0.80, 0.90%) and NPP (0.30, 0.35, 0.40%) for 28 d. The dietary Ca level affected the ADFI of yellow-feathered broilers ( P < 0.05), and the ADFI of birds fed with 0.90% Ca was increased ( P < 0.05) compared with that of birds fed with 0.70% Ca. Birds received 0.35 or 0.40% NPP had higher final BW, ADG, and ADFI than those fed with 0.30% NPP ( P < 0.05). The tibial diameter of birds fed with 0.80% Ca was increased compared with that of other groups ( P < 0.05). The dietary NPP level did not affect tibial characteristics ( P > 0.05). The dietary Ca level did not affect carcass traits ( P > 0.05). When broilers were fed with 0.30% P, the semieviscerated percentage was increased compared with birds fed with 0.40% NPP ( P < 0.05). The dietary Ca level had significant effects on the L∗ value and shear force of the breast muscle, and the dietary NPP level affected the L∗ value and drip loss of the breast muscle ( P < 0.05). Furthermore, the effect of interaction between the level of Ca and NPP was observed on the L∗ and a∗ value ( P < 0.05). In conclusion, dietary Ca had influence on performance, tibial characteristics, and meat quality of yellow-feathered broilers, and dietary NPP affected performance, tibial characteristics, and carcass traits. Furthermore, the effect of interaction between the dietary Ca and NPP level was observed on carcass traits and meat quality. Considering all aforementioned indicators, 0.80% Ca and 0.35% NPP were recommended for slow-growing yellow-feathered broilers aged 57 to 84 d of age.

Nutrition is defined as it relates to deficiencies, toxicities, and physiological states in birds. Levels of some nutrient requirements are given along with signs of deficiency. Signs of toxicity and the levels of nutrients required to produce them are discussed for energy, calcium, and protein. Behavioral aspects of nutrition in weaning, obesity, and dietary changes are characterized. The role of nutrition in diseases such as infection, hemochromatosis, achromatosis, gout, liver disease, and kidney disease are discussed.
