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.

This study aimed to investigate the effects of dietary fumaric acid (FA) on growth performance, immune responses, immune organ index and antioxidant status in broilers under chronic heat stress (HS). A total of 200 21-day-old Ross 308 chicks were randomly assigned in a 2 × 2 factorial arrangement with two diets (basal diet or 10 g/kg FA diet) and two temperatures (thermoneutral or HS) for 21 days. On day 42, growth performance, immune organ index, immune function and antioxidative ability were determined. HS resulted in a significant reduction in final body weight (FBW), average daily feed intake (ADFI), average daily gain (ADG), antibody titres against sheep red blood cells (SRBC) and Newcastle disease virus, IgM, IgG, relative weights of spleen, thymus and bursa of Fabricius, but a significant increase in the feed conversion ratio (FCR), activities of total superoxide dismutase (T-SOD) and glutathione peroxidase (GPx) in the bursa, contents of malondialdehyde and total carbonyl (TC) in thymus and bursa (P &lt; 0.05). Dietary supplementation of FA increased FBW, ADFI, ADG, antibody titres against SRBC, IgG, relative weights of spleen and bursa, activity of GPx in thymus and bursa, whereas it decreased the FCR and TC of thymus and bursa. These results suggest that dietary 10 g/kg FA had positive effects on growth performance and immune function through improving the antioxidative capacity of immune organs.

Objective: This study was conducted to investigate the effects of normal and heat stress environments on growth performance and, selected physiological and immunological parameters, caecal microflora and meat quality in Cobb 500 and Ross 308 broilers.Methods: One-hundred-and-twenty male broiler chicks from each strain (one-day-old) were randomly assigned in groups of 10 to 24 battery cages. Ambient temperature on day (d) 1 was set at 32°C and gradually reduced to 23°C on d 21. From d 22 to 35, equal numbers of birds from each strain were exposed to a temperature of either 23°C throughout (normal) or 34°C for 6 h (heat stress).Results: From d 1 to 21, strain had no effect (p>0.05) on feed intake (FI), body weight gain (BWG), or the feed conversion ratio (FCR). Except for creatine kinase, no strain×temperature interactions were observed for all the parameters measured. Regardless of strain, heat exposure significantly (p<0.05) reduced FI and BWG (d 22 to 35 and 1 to 35), immunoglobulin Y (IgY) and IgM, while increased FCR (d 22 to 35 and 1 to 35) and serum levels of glucose and acute phase proteins (APPs). Regardless of temperature, the Ross 308 birds had significantly (p<0.05) lower IgA and higher finisher and overall BWG compared to Cobb 500.Conclusion: The present study suggests that the detrimental effects of heat stress are consistent across commercial broiler strains because there were no significant strain×temperature interactions for growth performance, serum APPs and immunoglobulin responses, meat quality, and ceacal microflora population.
