Heat stress relief for broiler chickens: organic selenium and a vitamin C and E blend can enhance growth, nutrient digestibility, and blood parameters

This study aimed to evaluate the effects of dietary supplementation with organic selenium (OR-Se) and/or vitamins C and E on the rectal temperature (Rectal-T), growth performance, carcase yield, intestinal morphology, plasma thyroid hormone levels, and antioxidant status of broilers reared in hot environmental conditions. Under heat stress conditions (29.4 to 33.6 °C), 360 Arbour Acres chicks were fed in a (2 × 3) factorial design with two dietary levels of organic selenium (0 and 0.6 mg/kg) and three dietary levels of a mix of vitamins C and E (0, 200 and 250 mg/kg). Chicks were randomly assigned to six treatments (T) with three replicates of 20 birds each: the 1st group (T1): basal diet with no supplementation (control group); the 2nd group (T2): basal diet supplemented with 0.6 mg OR-Se/kg; the 3rd group (T3): basal diet with a mixture of vitamins C and E, 200 mg of each/kg diet (Vita-Mix A); the 4th group …

Efficacy of Dietary Supplementation with Zinc-Chromium Mixture, Organic Selenium, or Their Combinations on Growth Performance, Carcass Traits, and Blood Profiles of Broilers …

Simple Summary The need for methods to lessen the impacts of heat stress has increased due to climate change. The addition of trace elements to the food of chicks is an approach used to enhance production yield while boosting grill productivity. In livestock production, selenium is a crucial trace mineral for improved performance, physiological state, and health advantages. Numerous studies have examined the advantages and uses of both organic and inorganic selenium in poultry feeding. On the other hand, there is a dearth of knowledge on the use of organic selenium in heat-stress situations. In this work, we assessed the impact of dietary organic selenium on broiler growth performance, carcass characteristics, and blood profiles under heat stress, with or without a zinc-chromium mixture. According to the findings, adding organic selenized yeast improves the haematological, biochemical, and antioxidant status of broilers as well as their productivity. The weights and carcass qualities of the birds given Zn-Cr plus low or high Se levels were improved. In light of this, we concluded that the combined effect of feed additives (Zn-Cr and organic-Se) could reduce the effects of heat stress on broilers by increasing metabolic processes and enhancing growth performance. Abstract To determine the effects of organic selenium (0.0–0.6 mg and 0.9 mg Se/Kg diet) and Zn-Cr mixture (100 mg Zn/Kg diet plus 1.5 mg Cr/Kg diet) on broiler chicken performance, carcass traits, blood hematology, and biochemistry under heat stress conditions, this study was conducted. Under temperatures between 30.21 to 31.82 °C, 240 …

Efficacy of licorice extract on the growth performance, carcass characteristics, blood indices and antioxidants capacity in broilers

Some studies have suggested that dietary medicinal plants or herbs may have a variety of biological functions such as anti-inflammatory, antiallergic, antifungal, antioxidative stress, and anticarcinogenic activities. The present study was undertaken to assess the incorporation of the extract of licorice supplementation on the growth performance, carcass yield, blood indices, and antioxidative capacity in broilers. Three hundred twenty unsexed one-day-old Ross 308 broiler chicks were allocated randomly into four groups. Chicks in each group were randomly subdivided into eight replicates of ten chicks. The first group received a basal diet and was considered a control. The respective groups received a basal diet supplemented with 1, 2, and 3 g licorice extract/kg diet. The obtained results indicated that supplementation of licorice extract to broiler chicks resulted in heavier BW and weight gain and a better feed …

EVALUATION OF ORGANIC SELENIUM ON PRODUCTIVE PERFORMANCE, BLOOD BIOCHEMICAL PROPERTIES AND ANTIOXIDANT STATUS OF GROWING RABBITS UNDER HOT CLIMATE

The effect of organic selenium (OR-Se) based on Selenomethionine produced by Saccharomyces cerevisiae (Alkosel® NCYC R397) on the growth performance, carcass traits, blood hematological and biochemical indices and antioxidant status of growing rabbits under high ambient temperature. In an 8-week experimental period, a total of 48 New Zealand White rabbits were randomly distributed into 4 groups. Animals were allotted into 4 groups: control (basal diet) and T1, T2, T3 that were fed the basal diet supplemented with 0.4, 0.8 and 1.2 mg OR-Se/kg diet, respectively. Results showed that stressed rabbits in OR-Se-supplemented groups had a significant improvement (p<0.01) in growth parameters (except feed intake), dressing percentage and abdominal fat. In addition that, the supplemented groups (T2, T3) recorded higher levels (p<0.05) in red blood cells, hemoglobin, and packed cell volume. And these groups had a notable increase (p<0.05) in serum total protein and globulin and a decline in total cholesterol and triglycerides. In connection supplemented OR-Se statistically (p<0.01) increased serum total antioxidant capacity and declined Malondialdehyde compared with the control. Our findings of this study concluded that the supplementation of growing rabbit diets with OR-Se under hot times can alleviate the adverse effects of heat stress by improvement of the antioxidant status that reflected on growth performance, carcass characteristics and blood parameters.

Effect of dietary organic selenium on productive performance of broiler chickens under summer conditions

This work was conducted to evaluate the effect of dietary organic selenium (OR-Se) supplementation on growth performance, carcass traits, nutrient digestibility, blood metabolites, and antioxidant capacity of broiler chicks that reared in a high temperature environment. A total number of 320 one-day old unsexed chicks (Cobb-500) were raised during summer season under temperature ranged between 29.9 to 33.3 °C. Birds were randomly assigned to four treatment groups of 80 chicks each, with four replicates each of 20 chicks, kept in floor pens. The 1st group (T1) was fed basal diet, while the 2nd, 3rd and 4th groups (T2, T3, and T4) were fed diets supplemented with 0.3, 0.6 and 0.9 mg OR-Se/kg diet, respectively. The obtained results indicated that, groups supplemented with 0.6 and 0.9 mg OR-Se (T3 and T4) significantly improved growth parameters (body weight, body weight gain, feed conversion ratio), and nutrients digestibility. Also, these groups had higher (P< 0.05) carcass weight and lower (P< 0.05) abdominal fat. Besides, blood parameters including red blood cells, haemoglobin and haematocrit concentrations of chicks in these groups were clearly increased in comparison with chicks (T2) or the control group (T1). Furthermore, adding OR-Se to broiler diets statistically enhanced lipid profile, liver enzymes, kidney function, and antioxidant activity under high temperature environment. It could be concluded that dietary supplementation with OR-Se (0.6 and 0.9 mg/kg diet) had a positive effects on productive performance of broilers by improving growth performance, digestibility of nutrients, blood metabolites, and antioxidant capacity of …

Modulatory Effects of Arctostaphylos uva-urs Extract In Ovo Injected into Broiler Embryos Contaminated by Aflatoxin B1

Simple Summary The poultry industry is of great importance worldwide; however, mycotoxins contamination, especially aflatoxins, has harmful effects on poultry production. Therefore, finding out new strategies to alleviate aflatoxin contamination is an important trend of research. In our study, we focused on the in ovo injection techniques using the methanolic extract of brae beery “Arctostaphylos uva-ursi” (Ar. uu) to modulate the aflatoxinB1 (AFB1) adverse effects in broiler embryos. As a result, 0.1 g of Ar. uu in ovo injection alleviates AFB1 embryotoxicity by enhancing chicks’ physiological responses and optimizing antioxidant status, which is reflected in a low mortality rate and heavier relative weight of the hatched chicks. The in ovo injection of AFB1 + Ar. uu significantly declined AFB1-induced toxicity in embryos and increased broiler chicks embryo’s survival by 62.5%, increased relative embryo weight by ∼65.25% compared to eggs injected with AFB1 alone. Regarding immune responses, the in ovo injection of Ar. uu enhances the embryo’s humoral immune responses and regulates oxidative stress biomarkers. In general, the in ovo injection of Ar. uu modulates broiler chicks’ embryotoxicity caused by AFB1. Abstract In ovo injection of nutrients can modulate the embryo’s physiological responses against aflatoxin B1 (AFB1) embryotoxicity. This hypothesis was tested using in ovo injection of Arctostaphylos uva-ursi (Ar. uu.) methanolic extract. The total polyphenols, total flavonoids, total antioxidant capacity, and GC-MS analysis were all assessed in the Ar. uu. methanolic extract. A total of 180 ten-day-old …
