Effects of dietary supplementation of organic minerals on the performance of broiler chicks fed oxidised soybean oil

Abstract

SummaryThe oxidation (rancidity) of fat is a very common feed quality issue, which can negatively affect growth performance and meat quality of broilers. Besides other factors, metal ions such as Zn, Cu and Fe can facilitate lipid peroxidation in feed. The objective of the current study was to investigate the effect of feeding corn soy diets containing fresh or oxidised soybean oil with different forms of microminerals on production performance of broiler chicks. Dietary treatments consisted of a 2 × 2 factorial structure with two kinds of soybean oil (oxidised or fresh) and two forms of microminerals (inorganic or organic). Mineral proteinate (Bioplex®, Alltech Inc.) including Zn, Mn, Cu and Fe was used as the organic source and was supplemented at the level equivalent to 25% of an inorganic source in the control diets. Organic selenium (Sel-Plex®, Alltech Inc.) at 0.3 mg/kg of diet was used to replace sodium selenite used at 0.3 mg/kg of diet in control diet. Oxidised soybean oil was prepared by convection heat (90°C for a period of seven days in a convection oven). A total of 1152 one-day old chicks were allotted randomly to the four dietary treatments using 12 replicates of 24 chicks per pen. Chicks were raised in floor pens for 42 days in an environmentally controlled room with free access to feed and water. There was no statistical interaction between oil source and mineral form on performance or mineral content of breast meat. Feeding oxidised oil increased (P < 0.05) feed intake and decreased gain to feed ratio (FCE) of chicks. Supplementation with organic minerals improved (P < 0.05) weight gain and FCE of chicks. The breast meat of chicks fed organic mineral had higher (P < 0.01) Se content than those from the control group. The results indicated that the addition of organic minerals to broiler diets can minimise the negative impact of oxidised oil on the performance of broiler chicks.

Nutritional Intervention Strategies Using Dietary Antioxidants and Organic Trace Minerals to Reduce the Incidence of Wooden Breast and Other Carcass Quality Defects in Broiler Birds

“…Based on this information, experiment 1 was conducted to confirm the association between oxidized fat as a source of oxidative stress on the incidence of WB and evaluate the effect of proven nutritional antioxidant intervention. As expected, oxidized fat had an impact ( P < 0.05) on the performance of birds ( Table 3 ) in accordance with previous reports ( Dibner et al, 1996 ; Ao et al, 2017 ). A factorial analysis of live body weight for the effect of fat type showed that birds fed with oxidized fat (4.65 ± 0.04 kg) had lower ( P < 0.05) live weight than birds fed with fresh fat (4.82 ± 0.04 kg).…”

“…A factorial analysis of live body weight for the effect of fat type showed that birds fed with oxidized fat (4.65 ± 0.04 kg) had lower ( P < 0.05) live weight than birds fed with fresh fat (4.82 ± 0.04 kg). Previous studies have shown that presence of oxidized fat in the diet can destroy other nutrients in the diet matrix such as protein and fat-soluble vitamins ( Sheehy et al, 1994 ; Zdunczyk et al, 2002 ) and increase oxidative stress related damages in tissue ( Dibner et al, 1996 ) leading to reduced performance in broiler birds ( Ao et al, 2017 ). However, there were no effects ( P > 0.05) of oxidized fat on other carcass weight and yield parameters ( Table 3 ) in the present study.…”

Effects of dietary organic minerals, fish oil, and hydrolyzed collagen on growth performance and tibia characteristics of broiler chickens

“…As a result of this, lower FCR values for ORM and COL diet groups throughout the growing period, specifically during the finisher diet phase were found. These results on FCR are in accordance with previous studies, stating that broiler chickens fed organic Ca, P, Cu, Fe, Mn, Zn had lower FCR levels (Nollet et al., 2007; Abdallah et al., 2009; Tahir et al., 2012; Oliveira et al., 2015; Ao et al., 2017) than broiler chickens fed inorganic mineral varieties, probably again due to the higher bio-availability of the ORM varieties.…”

“…At day 42, the chickens of the COL and ORM diet groups had a higher BW compared to the FISH diet group. The findings of the ORM diet group are in line with previous studies that showed that dietary organic sourced Ca and P (Tahir et al., 2012) and Cu, Fe, Mn, Zn (Bao et al., 2007; Abdallah et al., 2009; Ao et al., 2017) resulted in higher growth performance than their inorganic varieties, because of their functions in numerous biochemical reactions, increased bio-availability, and less antagonistic impact among each other. It can be speculated whether or not an increase of inorganic minerals compared to the current guidelines will result in comparable effects as when ORM are used.…”
