Oil Blend

This study evaluated the effect of an essential oil blend and its delivery routes on broiler chicken growth performance, blood biochemistry, intestinal morphology, and immune and antioxidant status. Eggs were incubated and allotted to 3 groups: non-injected group, in ovo saline group, and in ovo essential oil group. On d 18 of incubation, essential oil in saline or saline alone was injected into the amnion. At hatch, chicks were assigned to post-hatch treatment combinations (1) in ovo essential oil + in-water essential oil (in ovo + in-water EO); (2) in ovo essential oil (in ovo EO); (3) in ovo saline; (4) in-water essential oil; (5) in-feed antibiotics (Bacitracin methylene disalicylate) and (6) a negative control (NC; corn-wheat-soybean diet) in 8 replicate cages (6 birds/cage) and raised for 28 d. The in ovo EO group reduced (p < 0.05) chick length and hatchability, all groups recorded no difference in growth performance at 0–28 d. The in ovo + in-water EO treatment reduced (p < 0.05) blood creatine kinase and aspartate aminotransferase levels whilst increasing (p < 0.05) total antioxidant capacity in birds. The in ovo + in-water delivery of EO might represent a potential antibiotic reduction strategy for the poultry industry but more research is needed to address the concern of reduced hatchability.

In Ovo Injection

The aim of this study was to explore the outcomes of an in ovo GABA injection in broilers challenged with HS. In Experiment 1, 210 Arbor Acres eggs were allocated to five treatments: no-injection, and in ovo injection of 0.6 mL of 0%, 5%, 10%, or 20% of GABA. Hatchling weight and CWEWR were significantly increased in the 5% GABA group. In ovo, injection of 10% GABA solution caused a significant decrease in plasma cholesterol and increased plasma total antioxidant capacity of hatchlings. Experiment 2 was conducted with 126 fertile Arbor Acres eggs distributed into one of two groups. At 17.5 days of incubation, one received no injection, and the other was fed 0.6 mL of 10% GABA. On day 10, one subgroup (4 replicates * 3 birds) from each treatment was submitted to HS (38 ± 1 °C for 3 h) while the other was kept at a thermoneutral temperature (29 ± 1 °C). An in ovo injection of GABA significantly increased total antioxidant capacity, but reduced malondialdehyde levels, hepatic mRNA levels of HSP70, FAS, and L-FABP with HS. In conclusion, an in ovo GABA injection improves CWEWR and antioxidant status at hatch, and enhances antioxidant status while downregulating the expression of HSP70 and fatty acid metabolism-related genes in young chicks under HS.

A total of 144 ostrich eggs (24 per group) were injected with 4 mL of physiological saline solution [positive control (PC)], carbohydrates (CHO — 20% maltose, 2.5% sucrose, and 2.5% dextrin), β-hydroxy-β-methylbutyrate (HMB), vitamin B6 solution, and vitamin D3 (vit D3) solution at 38 d of incubation. Injection of 4 mL physiological saline decreased the hatchability compared with negative control (NC) group (not injected eggs) (68.5% vs. 71.7%; P < 0.05). There was also lower hatchability and more number of embryonic deaths before piping in vitamin-injected group (72.2%). Heart, gizzard, pancreas, spleen and thymus, ileum, cecum, and rectum relative weight were not significantly different among treatments at hatch (P > 0.05). Carbohydrates group had higher duodenum and jejunum relative weight, whereas NC and PC groups had the least duodenum, jejunum relative weight (P < 0.05). Vit D3 injection increased bone strength, fresh and dry bone relative weight (P < 0.01). Chicks from HMB and CHO group had the highest levels of glycogen in the livers, whereas PC, NC, and vit D3 exhibited very low levels of glycogen in their liver (P = 0.014). Vitamins in ovo injected groups had the least duodenum villus height and also vit D3 group had the least jejunum villus height (P < 0.01). In conclusion, the use of CHO for the in ovo injection of ostrich hatching eggs would be practical in industry due to improvement in hatchability, bone characteristics, small intestine villus height and capacity, and also liver glycogen sources.

The aim of this study was to determine the effects of four essential oils intake by feed, namely Origanum vulgare, Thymus vulgaris, Cinnamomum zeylanicum Ness, and Syzygium aromaticum on antioxidant status in mice in vivo. Essential oils were in the aether oleum form. They were diluted with ethanol absolute mixed with ground pelett (0.1, 0.25, 0.57 and 1% concentration) and thereafter ethanol was evaporated. SOD, GPx activities and TAS were measured in erythrocytes and plasma spectrophotometrically with Ransod, Ransel and TAS kits from RANDOX, respectively. GPX activity showed a significant increase in 0.25% and 0.1% concentration of Origani aetheroleum. The GPx activities were decreased in 1% concentration of Thymi aetheroleum and 0.57% concentration of Cinnamomi aetheroleum and 0.57% concentration of Caryophylli aetheroleum. The total antioxidant status showed a significant decrease in 1 % concentration of Origani aetheroleum and significantly increased in 0.1% concentration. The same results were found in Thymi aetheroleum. Cinnamomi aetheroleum and Caryophylli aetheroleum had not effect on total antioxidant status. SOD activities were not significantly changed after intake of essential oils. In conclusion, our results showed, that concentration of essential oil is very important for antioxidant status and also for metabolism of mice, because a high dose of essential oil has adverse effect on metabolism of mice, representated by a lower growth of the body weight. On the other hand, essential oils at lower concentrations have positive effect on antioxidant status of mice.

This study was conducted to investigate the effects of in ovo and post-hatching supplementation with L-Glutamine (Gln) on hatching characteristics, performance, small intestinal morphology, and muscle development of broilers. At day 18 of incubation, 960 fertilized eggs were allocated to four treatments with six replicates. Eggs were i) not injected (negative control) (NC), ii) subject to the standard incubation procedure (PG), iii) injected with 1 ml sterile solution with 0.9% salt (positive control) (PC), and iv) injected with 1% Gln solution (IG). On hatching, the SC chicks were fed with 1% Gln for seven days. The remaining chicks were fed a commercial starter feed. After hatching, there were six replicates of 28 birds in each treatment. Hatchability and yolk sac weight were lower and yolk-free chick weight (YFCW), whole gastrointestinal tract (GIT) and breast muscle weights were higher at hatching for chicks from the IG treatment. At 42 days old, feed conversation ratio (FCR) was lower in birds that had Gln added to their diet than for the other treatments. The FCR was also lower in IG birds than birds in the NC group. The GIT weight, villus height, villus width and crypt depth of the birds receiving dietary supplementation of Gln were greater than those of birds in PC and IG. Thus, in ovo injection of Gln improved hatching characteristics except for hatchability. Further, in ovo and dietary Gln administration reduced FCR by stimulating digestive system development.

Abstract This study investigated the effects of encapsulated citral (CIT) and cinnamaldehyde (CIN) on growth performance, intestinal morphology and meat quality in broilers. A total of 320 0-day-age male broilers (Cobb 500) were allocated 32 pens with 8 pens per treatment. The treatments included: 1) Corn-wheat-SBM basal diet (negative control); 2) basal diet with 30 ppm avilamycin premix (positive control); 3) basal diet with 50 ppm encapsulated CIT and CIN (CCL); 4) basal diet with 100 ppm encapsulated CIT and CIN (CCH). There were no significant differences between treatments in growth performance (P &gt; 0.05) at each feeding stage. Additionally, birds had similar relative organ weights of heart, liver, spleen and bursa (P &gt; 0.05). The higher ratios of villus height to crypt depth (VCR; P ≤ 0.05) were detected in broilers fed either CCL or CCH, with an average being 14.67 and 15.13 in the duodenum, and 15.13 and 13.58 in the jejunum, respectively. Regarding meat quality, a higher pH value (pH = 6.21) in the breast was observed in 24-h post mortem chickens fed CCL (P ≤ 0.05). No significant differences of pH were detected in the breast in 96-h post mortem birds. The breast color (redness, yellowness, and lightness) in either 24-h or 96-h post mortem chickens was not significantly different among treatments (P &gt; 0.05). No change in purge loss (%) was observed in the breast after 48 h. The severity of white striping (WS) or woody meat (WB) was higher in the positive control (WS = 0.58; WB = 0.15) than in other treatments (P ≤ 0.05). In conclusion, dietary treatment with encapsulated CIT and CIN improved gut morphology and meat quality of broilers by increasing VCR in the small intestine and reducing the severity of WS/WB in the breast, respectively, without affecting growth performance.

Abstract Background: Compared to the corresponding source of inorganic trace minerals (TM), chelated supplements are characterized by better physical heterogeneity and chemical stability and appear to be better absorbed in the gut due to possibly decreased interaction with other feed components. This study was designed in broiler chickens to determine the effects of replacing 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 TM at 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 indicate that while CTM supplementation 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.
