Effect of Advanced Chelate Technology Based Trace Minerals on Growth Performance, Mineral Digestibility, Tibia Characteristics, and Antioxidant Status in Broiler Chickens

Abstract Background: Compared to the corresponding source of inorganic trace minerals (TM), chelated supplements arecharacterized by better physical heterogeneity and chemical stability and appear to be better absorbed in the gut due to possiblydecreased interaction with other feed components.Methods:This study was designedin broiler chickens to determine theeffects ofreplacing inorganic trace minerals (TM) with an advanced chelate technology based supplement(Bonzachicken) on growth performance, mineral digestibility, tibia bone quality, and antioxidant status. A total of 625 male 1-d-old broiler chickens were allocated to 25 pens and assigned to 5 dietary treatments in a completely randomized design.Chelated TM (CTM) supplement was compared at 3 levels to no TM(NTM) or inorganic TM. A corn–soy-based control diet was supplemented with inorganic TMat the commercially recommended levels (ITM), i.e., iron, zinc, manganese, copper, selenium, iodine, and chromium at 80, 92, 100, 16, 0.3, 1.2, and 0.1 mg/kg, respectively, and varying concentration of CTM, i.e., match to 25, 50, and 100 % of the ITM (diets CTM25, CTM50, and CTM100, respectively).Results: All diets, except diet CTM25, increased average daily gain (ADG), European performance index (EPI), and serum total antioxidant capacity compared to the NTM diet (P < 0.05). Broilers fed the CTM100 diet had lowest overall FCR and highest BWG, EPI, tibia ash, zinc, and manganese contents (P < 0.05). The tibia phosphorus content and apparent ileal digestibilities of phosphorus, zinc, and manganese were lower in the ITM group compared with the CTM50 and CTM100 groups (P < 0.05). Broiler chickens fed any of the diets exhibited higher serum glutathione peroxidase and superoxide dismutase activities and lower malondialdehyde level than those fed the NTM diet, where the best values were found for CTM100 treatment (P < 0.05).Conclusions: These results indicatethat while CTMsupplementation to 25 and 50% of the commercially recommended levels could support growth performance, a totally replacing ITM by equivalent levels of CTM could also improve growth performance, bone mineralization and antioxidant status of broiler chickens under the conditions of this study.

AbstractA 35-day experiment was carried out to study the effects of acidified and alkalinized diets on zootechnical indices, tibial calcium and phosphorous retention, bone mineralization and liver enzymes activity using 250 Ross 308 male broiler chicks. Five treatments consisting of a control diet (CD), CD acidified using 10, 20 and 30 g/kg citric acid (CA) and CD alkalinized with Ca (OH)2 (8.9 g/kg in growth period and 8.6 g/kg in finisher period) were examined in 5 replicates of 10 birds each from day 7 up to day 42 of age. Inclusion of 30 g/kg CA significantly increased body weight, average daily gain (ADG), average daily feed intake (ADFI), feed efficiency, tibia ash, tibia Ca content, at day 42 of age (P<0.05). Serum alkaline phosphatase and lactate dehydrogenase activities were elevated in the birds fed with the 30 g/kg CA-treated diet at day 42 of age (P<0.05). Alkalinized diet significantly reduced ADFI, tibia ash, tibial P and Ca contents, bone breaking strength and plasma Ca concentration (P<0.05). It was concluded that the diet acidified with 30 g/kg CA promoted productive performance and tibia mineralization in broiler chicken. Alkalinized diet suppressed growth performance of the birds perhaps through disrupted mineral absorption and altered liver enzymes activity.

A 49 day feeding trial was conducted to determine the effect of biologically upgraded cocoa pod husk meal (BCPHM) on the growth performance, haemato-biochemical indices and antioxidant status of broiler chickens. Three experimental diets were formulated at both starter and finisher phases in which BCPHM was added as an active feed ingredient at 0, 10, 20% and designated as diets 1, 2 and 3 respectively. One hundred and fifty day old Marshal broiler chicks weighing 39±2.5g/bird were allotted to 3 dietary treatments (10birds/replicate, 50birds/treatment) in a completely randomized design. The Average daily weight gain (ADWG), total weight gain (TWG) and final body weight (FBW) of broiler chicks fed diets containing 10% BCPHM was significantly (p˂0.05) higher than that of control and diet containing 20% BCPHM at starter phase. At finisher phase, the values of ADWG, TWG and FBW were at par with that of control. Feed Intake was seen to increase as BCPHM increased in the diet at finisher phase. Carcass traits, relative internal organ weight, haemato-biochemcal indices of broiler chickens were similar across dietary treatment. Superoxide dimutase (SOD) and Catalase (CAT) of birds fed control diet were significantly (p˂0.05) higher than those of birds fed BCPHM based diets. Ten percent dietary inclusion of BCPHM appears optimal in broiler diet since beyond this level growth performance declined.

Dietary Treatments

The effects of organic selenium (Se) supplementation of diets for broiler chickens were evaluated in the present study. Broiler diets had average background Se concentrations of 0.36 mg/kg Se (control diet) and were supplemented with two organic Se sources, namely BiOnyc® Tor-Sel (selenohomolanthionine = SH) and Alltech’s Sel PlexTM (selenomethionine = SM); their addition increased dietary selenium concentrations by an average of 0.57 mg/kg Se. Their effects on growth performance, nutrient utilisation and oxidative status of broiler chickens were determined. Growth performance was very similar across all dietary treatments; in contrast, significant differences in nutrient utilisation were observed. The N-corrected apparent metabolisable energy value for the control group (14.14 MJ/kg) and SH (14.15 MJ/kg) diet was significantly (P < 0.01) higher than that for the SM (13.64 MJ/kg) diet. Alternatively, N retention with the SM (68.4%) diet was significantly (P < 0.005) higher than that for the control (65.2%) and SH (64.5%) diets. Neither of the Se sources influenced plasma concentrations of reactive oxygen metabolites, biological antioxidant potential and advanced oxidation protein products. The activity of glutathione peroxidase, superoxide dismutase in both plasma and tissues samples and the concentration of plasma glutathione were increased by SH and SM compared with the control group. Our findings suggest that SH and SM improved the antioxidant status of broilers by elevating activities of antioxidant enzymes and concentrations of antioxidant. Both Se supplements significantly (P < 0.001) increased Se concentrations in liver and muscle, and in liver tissue there was no statistical difference between the two supplements. However, SH generated significantly higher Se concentrations in muscle tissue (0.283 versus 0.257; P < 0.005) than did SM. In summary, SH was at least the equivalent to SM as a source of organic Se for broiler chickens under the conditions of the present feeding study. This is reflected in the outcome that SH generated significantly higher Se concentrations in muscle tissue than did the alternative Se supplement.

Abstract A total of 1,089 pigs (PIC 280 × 1050; initially 37.3 ± 2.8 kg) were used to determine the effects of increasing Cu provided from either CuSO4 alone or a 50:50 blend of CuSO4 and a Copper–amino acid complex (Cu-AA) on growth performance and carcass characteristics of finishing pigs. Pens of pigs were blocked by body weight; within blocks, pens were randomly allotted to one of six dietary treatments. The six dietary treatments consisted of a control diet which contained 17 mg/kg Cu from CuSO4 from the trace mineral premix, or the control diet with either added CuSO4 to provide 70 and 130 mg/kg total Cu or a 50:50 blend of Cu from CuSO4 and Cu-AA (CuSO4/Cu-AA blend) to provide 70, 100, and 130 mg/kg total Cu. Experimental diets were corn–soybean meal-dried distillers grains with solubles-based and fed in meal form in five phases (approximately 37 to 46, 46 to 63, 63 to 77, 77 to 103, and 103 to 129 kg body weight). From d 0 to 43, neither Cu source nor level influenced growth performance. From d 43 to 105, average daily feed intake (ADFI) decreased (P = 0.037) for pigs fed the CuSO4/Cu-AA blend compared to those fed added Cu from CuSO4 alone. Gain:feed ratio (G:F) tended to be improved (linear, P = 0.056) as Cu concentration increased. Overall, d 0 to 105, neither Cu level nor source influenced average daily gain (ADG). Pigs fed 70 or 130 mg/kg total added Cu from the CuSO4/Cu-AA blend had lower (P = 0.045) ADFI but G:F tended to be improved (P = 0.051) compared with those fed the same amount of total Cu from only CuSO4. Owing to the decreased ADFI and improved G:F of pigs fed the CuSO4/Cu-AA blend, carcass G:F also improved (P = 0.033) compared with those fed added Cu from CuSO4 alone. In conclusion, providing a 50:50 blend of CuSO4 and Cu-AA improved G:F on both a live and carcass weight basis compared to CuSO4 alone with no differences in ADG or carcass ADG observed.

Abstract Two experiments were conducted to determine the efficacy of various commercial products on growth performance of nursery pigs fed diets high in fumonisin. In experiment 1, 350 pigs (241 × 600; DNA, Columbus, NE; initially 9.9 kg) were used with five pigs per pen and 14 replicates per treatment. After weaning, pigs were fed common diets for 21 d before the experiment started. The five dietary treatments consisted of a positive control (low fumonisin), a negative control (60 mg/kg of fumonisin B1 + B2 in complete diet), and the negative control with one of three products (0.3% of Kallsil Dry, Kemin Industries Inc., Des Moines, IA; 0.3% of Feed Aid Wide Spectrum, NutriQuest, Mason City, IA; 0.17% of Biofix Select Pro, Biomin America Inc., Overland Park, KS). Diets were fed in mash form for 14 d and followed with a low fumonisin diet for 13 d. For the 14-d treatment period, pigs fed the positive control diet and Biofix Select Pro had greater (P < 0.05) average daily gain (ADG), average daily feed intake (ADFI), and gain:feed (G:F) compared to those fed the high fumonisin negative control, or high fumonisin diets with Kallsil Dry or Feed Aid Wide Spectrum. Serum sphinganine to sphingosine ratios (SA:SO) were greater (P < 0.05) in all pigs fed high fumonisin diets compared to the positive control. In experiment 2, 300 pigs (241 × 600; DNA; initially 10.4 kg) were used. Procedures were similar to experiment 1 except there were 12 replicate pens per treatment, high fumonisin diets contained 30 mg/kg fumonisin, and experimental diets were fed for 28 d. Similar to experiment 1, pigs fed the positive control diet and treatment with Biofix Select Pro had greater (P < 0.05) ADG and G:F, and lower (P < 0.05) serum SA:SO compared to pigs fed the high fumonisin negative control, or high fumonisin diets with Kallsil Dry or Feed Aid Wide Spectrum. In summary, pigs fed diets containing 60 mg/kg of fumonisin for 14 d or 30 mg/kg of fumonisin for 28 d had poorer ADG and G:F and greater serum SA:SO compared to pigs fed a diet with less than 5 mg/kg of fumonisin. Adding Biofix Select Pro to diets appeared to mitigate the negative effects of high fumonisin concentrations, while Kallsil Dry and Feed Aid Wide Spectrum did not.

A total of 320 pigs (body weight = 98 ± 4 kg) were assigned to four treatments, with eight replicates (pens) per treatment. Pigs were fed the following diets: a control diet (CON), the CON diet plus antioxidant blends (AOX), organic trace minerals (OTM), or both (AOX + OTM). After the feeding trial, two pigs from each pen were selected for slaughtering right away or after transportation. The inclusion of AOX, OTM, or AOX + OTM had no significant effect on feed intake, average daily gain, and feed efficiency compared with CON (P > 0.05). The pre-transportation significantly reduced the pH value of loin meat at 24 h post mortem and leg meat at 45 min post mortem (P < 0.05). The pigs in the AOX, OTM, and AOX + OTM group had significantly lower plasma malondialdehyde (MDA) content than the CON group (P < 0.05). Pre-transportation resulted in significantly higher meat MDA contents (P < 0.05), clearly influencing the oxidative stress of pigs. The inclusion of antioxidant blends or organic trace minerals had no significant effect on the growth performance and antioxidant capacity of finishing pigs.
