“…The increase in weight at slaughter and carcass might be caused by the increased nutrient digestibility, enzyme activity, and a favorable balance of the gastrointestinal microbiota induced by the addition of probiotics in the feed [3,35]. These data are in agreement with a previous work [36] showing an increase in carcass yield and relative weight of the intestinal tract, as well as a decrease in abdominal fat in the fermented canola meal group, compared with those of the groups receiving canola meal and canola meal with probiotics. The addition of probiotics in feed might lead to a higher carcass weight by increasing the availability of protein in the body [37].…”

“…The increase in the relative weight of the bursa of Fabricius is likely due to an increase in the lymphocyte levels induced by the addition of probiotic microbiota to stimulate the immune response of chickens [26,42]. The weight of other immune organs, such as the spleen and thymus, was not significantly different among treatment groups [36]. However, after probiotic administration, weighing lymphoid organs (spleen, bursa of Fabricius, and thymus) showed a significant change in the spleen relative weight on 42 days of age compared to the control group.…”

“…A significantly higher weight of immune organs (bursa of Fabricius) has been shown in animals fed with fermented canola meal and canola meal supplemented with probiotics compared with the weight in other treatment groups and control group [36]. The increase in the relative weight of the bursa of Fabricius is likely due to an increase in the lymphocyte levels induced by the addition of probiotic microbiota to stimulate the immune response of chickens [26,42].…”

Background and Aim: With the increased concerns about global protein supply, chicken meat, especially from male layer chicken, constitutes an alternative in terms of quality and carcass traits. Probiotics have been proposed for replacing antibiotic growth promoters (AGPs), which have been prohibited as poultry supplement feeds. The present study aimed to determine the efficacy of dietary supplementary probiotics during the starter period on growth performances, carcass traits, and immune organs of male layer chicken. Materials and Methods: In this study, one hundred and eighty 1-day-old male chicks from the strain ISA brown were used. They were divided into six groups according to the feed: 100% basal feed (T0), basal feed+2.5 g AGP/kg feed (T1), basal feed+probiotics 1 mL/kg feed (T2), basal feed+probiotics 3 mL/kg feed (T3), basal feed+probiotics 4 mL/kg feed (T4), and basal feed+probiotics 5 mL/kg feed (T5). Probiotics (Lactobacillus acidophilus, Lactobacillus plantarum, and Bifidobacterium spp.) were given at a concentration of 1.2×109 colony-forming unit/mL. Virginiamycin was used as AGP. ISA brown layer chicken was treated for 21 days. Growth performances (body weight, feed consumption, and feed conversion ratio [FCR]), carcass traits (weight at slaughter, weight of the carcass, breast muscles, liver, lungs, kidneys, and heart), immune organs (spleen, thymus, and bursa of Fabricius), and non-edible organs (head, legs, and wings) were analyzed. Results: Probiotic supplementation at 4 and 5 mL/kg feed (T4 and T5) during the starter phase improved the body weight, FCR, and feed consumption. The weight at slaughter, weight of the carcass, breast muscles, and liver from the T4 and T5 groups were significantly greater than those in the other treatment groups. In addition, the weight of the heart, lungs, and kidneys was increased in the T1, T2, T3, T4, and T5 groups compared with that measured in the T0 group. Furthermore, there were significant differences regarding the immune organs between the T0 and the other treatment groups. The weight of the head, legs, and wings was also greater in the probiotic and AGP supplementation groups (T1, T2, T3, T4, and T5) than that in the basal feed group (T0). Conclusion: Probiotic (L. acidophilus, L. plantarum, and Bifidobacterium spp.) supplementation at 4 and 5 mL/kg feed during the starter period can be used to improve the growth, carcass traits, and weight of immune organs in male layer chicken.

“…Interestingly, the authors showed a similar effect with unfermented rapeseed meals. Similar conclusions were reached by Elbaz [ 29 ], who observed the best intestinal health in birds fed with a fermented rapeseed meal compared to an unfermented one as well mix of rapeseed meal with probiotic and feed mixture without rapeseed. It is noteworthy that not all fermented protein alternatives carry positive effects as demonstrated by Choi et al [ 30 ] fermented seaweed fusiforme decreased Haugh’s units compared to fermented brown seaweed.…”

The most popular protein source in poultry feed mixtures is soybean. However, cheaper and more available alternative protein sources are being sought, and feed manufacturers more and more often turn their attention to the post-extraction meals of local oil plants, e.g., rapeseed. Therefore, the effect of fermented and non-fermented post-extraction rapeseed meal used as a feed additive for Japanese quails was investigated on the eggs’ quality. The study was performed on 280 females of Japanese quails fed with a mixture without rapeseed meal, with non-fermented post-extraction rapeseed meal (5%, 10% and 15%) and with fermented one (5%, 10% and 15%). During the experiment, eggs were collected from each group four times (every 4 weeks) and evaluated for their quality characteristics. The addition of 10% fermented rapeseed meal had the most beneficial effect on such eggs quality traits as egg weight, specific gravity, yolk index and color and albumen pH. However, in the majority of examined parameters, no significant differences were found between birds fed with soybean meal and those fed with fermented and non-fermented rapeseed meal (morphological elements proportions, yolk weight, albumen height and Haugh’s units, eggshell quality). This supports the thesis that the use of rapeseed meals instead of soybean meals may allow obtaining the proper quality of animal raw materials at a lower cost and with the use of local feed resources.

Effects of garlic and lemon essential oils on performance, digestibility, plasma metabolite, and intestinal health in broilers under environmental heat stress

et al. 2022

Background Natural feed additives play an important role in poultry production due to their safety and potential properties as an antioxidant and antimicrobial, as well as a growth stimulant. The present research was designed to assess the influence of dietary supplementation of either garlic, lemon essential oil, or their mixture on performance, nutrient digestibility, plasma constituents, immunity, and oxidative status, as well as intestinal development assessed by microbiota—histomorphology development in broilers under environmental heat stress. Methods A total of 480 broiler chicks (Ross 308) at one-day-old were randomly divided into four groups (120 chicks/ group). The control group received the basal diet (CON), while the other three groups received the basal diet supplemented with 200 mg/kg garlic essential oil (GEO), 200 mg/kg lemon essential oil (LEO), and their mixture (GLO) 200 mg/kg diet, respectively for 35 days. Results The obtained results revealed that broilers fed essential oils as a mixture or individually had an improvement in average body weight, feed conversion ratio, carcass dressing, and an increase in digestive enzymes activities compared to the control group, furthermore, there was a reduction in the mortality rate and abdominal fat content. Adding essential oils as a mixture or individually led to a decrease in (P < 0.05) blood plasma triglycerides, cholesterol, low-density lipoprotein, and an increase in high-density lipoprotein. Broilers fed diets supplemented with essential oils as a mixture or individually had higher values of superoxide dismutase and glutathione peroxidase; while plasma malondialdehyde was lower (P < 0.05) compared to the control diet. Moreover, there was a significant enhancement in intestinal microbial content, and intestinal histological status of chickens fed with essential oils. Conclusions Conclusively, including the mixture of essential oils improved performance, nutrient digestibility, and digestive enzymes activities. It also enhanced immunity, antioxidant state, and lipid profile, and gut microbiota— histomorphology in broilers. It was proposed that the broilers diet be supplemented with a mixture of essential oils to a mitigation of the effects of heat stress.
