“…Previous studies have shown that growth performance is a commonly used indicator for evaluating the Ca and P requirements of broilers during the starter phase ( Driver et al, 2005 ; Rao et al, 2006 ). Excessive amounts of Ca and P in the diet have negative impact on the growth of broilers ( Shafey et al, 1991 ; Wang et al, 2021 ). Gautier et al (2017) found that the decrease of dietary Ca and NPP improved the growth performance of broilers.…”

“…Interaction, especially antagonism among mineral elements, has been well-studied by nutritionists (13)(14)(15)(16)(17). Dietary Fe levels decreased Mn utilization in MnSO 4 -treated broilers but did not influence Mn utilization in MnLys-treated broilers.…”

“…Considering nutrient waste and the environmental threat, the European Union has set lower dietary allowances for trace minerals in response to high levels in manure ( 12 ). In fact, many minerals have interactions in the body, which further makes the research more complicated ( 13 , 14 ). Two types of relationships exist among trace minerals, antagonistic or synergistic, which occur at two stages, absorption and metabolism ( 15 ).…”

Integrated evaluation of the requirements and excretions of Cu, Fe, Zn, and Mn for broilers via a uniform design method

This study aimed to determine the ideal balance profile of Cu, Fe, Zn, and Mn for broilers of 1–21 days of age via a uniform experimental design. In Experiment 1, 900 1-day-old Arbor Acres male broilers were randomly allotted to 15 dietary treatments with six replicates of 10 birds. A total of 14 experimental diets were formulated with the supplementation of 8~16, 123~160, 40~80, and 60~120 mg/kg of Cu, Fe, Zn, and Mn, respectively, in the basal diet, according to the uniform design method. The excretion of Cu, Fe, Zn, and Mn in the manure and the broiler performance were determined to build the ideal balance profile of these elements. Experiment 2 was conducted based on the ideal balance profile built in Experiment 1, to test its practicability using 720 broilers with two treatments. The dietary concentrations of Cu, Fe, Zn, and Mn in the control group were 15.19, 203.08, 76.78, and 86.13 mg/kg, respectively. In Experiment 1, the concentrations of Cu, Fe, Zn, and Mn in the diets were 16.96, 166.66, 46.01, and 60.26 mg/kg, respectively, when the average daily gain reached the optimum value. When the dietary concentrations of Cu, Fe, Zn, and Mn were 8.54, 130.66, 38.19, and 64.07 mg/kg, respectively, the total excretion of Cu, Fe, Zn, and Mn got the minimum value. There are corresponding ideal balance profiles for minimum excretion of a certain element. In Experiment 2, the dietary levels of Fe, Zn, and Mn were decreased by 17.93%, 40.08%, and 30.04%, respectively, which had no significant effect on average daily gain, average daily feed intake, and feed gain for 1~21 day-old broilers but markedly decreased the excretion of Cu and Mn and total excretion. It was concluded that there is a dilemma between growth performance and mineral excretion. Although dietary levels of Cu, Fe, Zn, and Mn supporting optimal growth are higher than those for minimizing mineral excretion, supplementing too many trace elements in the diets of broilers is unnecessary.

“…Chinese yellow‐feather broilers grow very slowly. Report showed that body weight (BW) of local yellow‐feather male broilers was 373.4 g at Day 21 (Tang et al, 2021), and BW of slow‐growing meat‐type female yellow‐feathered broilers was 284.83 g at Day 28 (Wang, Wang, Fan, et al, 2021) and 704.63 g at Day 57, 1217.43 g at Day 84 (Wang, Wang, Li, et al, 2021). Little is known if the oligosaccharides mentioned above could attenuate oxidative stress and maintain growth performance at the same time.…”

In order to determine the effect of different oligosaccharides on growth performance, intestinal health, and antioxidant status of broilers, 240 1-day-old XiangHuang broilers were randomly distributed to 4 treatments with 6 replicates each. Birds were fed corn-soybean-based diets (CON), and birds in xylooligosaccharides (XOS), fructo-oligosaccharides (FOS), and iso-maltooligosaccharide (IMO) groups were given the basal diet supplemented with 200 mg/kg XOS, FOS, and IMO, respectively. Result showed that average daily gain (ADG) during the whole 5 weeks in FOS group was greater than that in control group (p < 0.05). Both breast
