“…In ovo feeding with zinc or iodine had higher growth‐related genes expression than the selenium or control (uninjected) group. Interleukin‐6 expression was higher in birds fed via in ovo supplementation of iodine at 2.5‐fold; however, it was lower in selenium and zinc in ovo feeding groups . In ovo selenium supplementation in tested broiler embryos caused a significant increase in activity of NK cells and lymphokine‐activated killer cells, T‐cell proliferation, an intensity of delayed‐type hypersensitivity skin responses, and vaccine‐induced immunity in experimental embryonated eggs .…”

In ovodelivery of various biological supplements, vaccines and drugs in poultry: current knowledge

The technique of delivering various nutrients, supplements, immunostimulants, vaccines, and drugs via the in ovo route is gaining wide attention among researchers worldwide for boosting production performance, immunity and safeguarding the health of poultry. It involves direct administration of the nutrients and biologics into poultry eggs during the incubation period and before the chicks hatch out. In ovo delivery of nutrients has been found to be more effective than post‐hatch administration in poultry production. The supplementation of feed additives, nutrients, hormones, probiotics, prebiotics, or their combination via in ovo techniques has shown diverse advantages for poultry products, such as improved growth performance and feed conversion efficiency, optimum development of the gastrointestinal tract, enhancing carcass yield, decreased embryo mortality, and enhanced immunity of poultry. In ovo delivery of vaccination has yielded a better response against various poultry pathogens than vaccination after hatch. So, this review has aimed to provide an insight on in ovo technology and its potential applications in poultry production to deliver different nutrients, supplements, beneficial microbes, vaccines, and drugs directly into the developing embryo to achieve an improvement in post‐hatch growth, immunity, and health of poultry. © 2019 Society of Chemical Industry

“…Furthermore, this technique ameliorated the immune response and increased the resistance against diseases, which resulted in low posthatch mortality and morbidity (Ferket, 2011). The micronutrients, vitamins, trace elements, amino acids, vaccines and functional feed additives can be injected to help the high-metabolism and fast-growing of broiler embryos (Bello, Hester, Gerard, Zhai, & Peebles, 2014;Foye, Ferket, & Uni, 2007;Goel, Bhanja, Mehra, Majumdar, & Pande, 2013;Goel, Bhanja, Mehra, Mandal, & Pande, 2016;Hassan, 2018;Lee et al, 2010;Macalintal, 2012;Pender et al, 2017;Sogunle, Elangovan, David, Ghosh, & Awachat, 2018;Zhai, Bennett, Gerard, Pulikanti, & Peebles, 2011).…”

In ovo injection of nano‐selenium (Se) produced by lactic acid bacteria (LAB–nano‐Se) was investigated on the hatchability, immune responses and the histopathological alterations in hatched chicks. The eggs (18 day age) were injected with 0.5 ml of 0.9% NaCl (normal saline, NS), while the control group was kept without injection. In the third, fourth and fifth groups, the eggs were injected with 0.5 ml of NS and LAB–nano‐Se at 10, 20 and 30 μg/egg. The results revealed improved growth performance in groups injected with LAB–nano‐Se when compared to the control treatment. The highest final weight and weight gain were noticed in 20 μg LAB–nano‐Se/egg group (p < .05). The feed conversion ratio was reduced in all treated groups when compared to the control group (p < .05). Groups injected with LAB–nano‐Se showed enhanced hatchability of the whole incubated eggs (p < .05). Total lipids and cholesterol levels were decreased significantly in groups treated with LAB–nano‐Se at 10 and 20 μg/egg when compared to the non‐treated group. At the same time, globulin was increased by LAB–nano‐Se in ovo injection. Furthermore, the total antioxidant capacity, catalase, glutathione peroxidase, superoxide dismutase increased in groups treated with LAB–nano‐Se at 10 and 20 μg/egg with insignificant (p > .05) differences with those treated with LAB–nano‐Se at 30 μg/egg using in ovo injection technique. Also, higher total blood protein and phagocytosis were significantly observed in groups treated with at 10, 20 and 30 μg LAB–nano‐Se/egg. The histopathological images of hatched chicks revealed that nano‐Se presented normal effects on liver and kidney tissues and restored the parameters as mentioned earlier. To conclude, LAB–nano‐Se exhibited beneficial effects in hatched chicks through improving immune and antioxidant activities as well as histopathological effects by using in ovo technique.

“…WBC or leukocytes play an important role in nonspecific or innate immunity and their counts can be considered as an indicator of the health status of broilers. LYM is an important leukocyte cell of the immune system that is involved in defending the body against both infectious diseases and external infectious microorganisms [40]. LYM count was found to be zero, while NEU counts were similar in all the groups.…”

Evaluation of Struvite Recovered from Swine Wastewater as an Alternative Phosphorus Source in Broiler Feed

et al. 2019

The objective of this study was to evaluate the feasibility of reutilizing phosphorus (P) recovered as struvite from swine wastewater as an alternative to commercial P sources in broiler feed. The recovered struvite was pre-treated as microwave irradiated struvite (MS) and incinerated struvite (IS) to reduce the NH4-N concentration in recovered struvite before application. A preliminary study on the growth performance and blood metabolites of broiler chickens was then performed to assess the effect of MS and IS by comparing with commercial monobasic dicalcium phosphate (MDCP, control). A total of 204 male Ross 308 broiler chickens (mean body weight (BW) of 80±5 g) were randomly allotted to each of 12 pens. The growth performance and blood metabolites analysis of broiler chickens showed no significant difference among the test materials (p > 0.05). However, the apparent total tract digestibility of crude fat was significantly higher in MS and IS treated groups compared to the control (p < 0.05). The digestibility of crude ash in control was significantly lower than that in MS (p < 0.05). The results suggested that P recovered from swine wastewater as struvite can be reutilized as an alternative P source in broiler feed without adverse effects on growth performance and blood metabolites through proper pre-treatment. To our knowledge, this is the first study to evaluate the potential of using struvite in animal feed. This study provides primary evidence for the safety and efficacy of using pre-treated struvite as an alternative source of P in animal feed and will encourage further studies with more rigorous design.
