“…probiotic and/or betaglucan prebiotic at 1 to 7 days of age; those authors reported no group-wise difference in the parameters of the duodenum and jejunum in the small intestine. Bueno et al (2012) evaluated the influence of probiotic supplementation on the intestinal morphology of birds; they reported a significant treatment effect at 42 days of age in birds supplemented with probiotics, and the result of their study was confirmed in the later studies. Moreover, those authors reported that probiotic added in the diet caused a reduction of the duodenum CD as compared to that by a control diet without probiotic, which conflicts with the result of lower duodenum villus height in the control group without probiotic versus the treatment group with probiotics of Pelicano et al (2003).…”

This study aimed to assess the histomorphometry of the intestinal portions (duodenum and jejunum) in broilers supplemented with probiotic, and histological parameters of their immune system components. Rhizomucor spp. originated from samples of the intestinal content in Cobb 500 chickens was evaluated; these fungi were submitted to performance assay and selected based on in vitro probiotic characteristics. Complete randomized design was used (3 treatments × 7 replicates; 18 birds per experimental unit). One bird at 21 and 42 days of age was sacrificed in each unit and the organs were sampled. In all samples, fixation was conducted followed in order by dehydration and diaphanization; analyses were conducted by light microscopy and histomorphometry, and search was performed for spots indicating the lesion's presence. At 21 days, the duodenum villus height was higher in the group receiving Rhizomucor spp. probiotic, and the jejunum villus height was significantly increased in both the control and Rhizomucor spp. probiotic groups. At 42 days, difference of the duodenum crypt depth was observed in the group receiving commercial probiotic. With regard to the tissue changes of the intestines, spleen, and bursa, no histological alterations were observed at 21 days in all birds (100%) receiving Rhizomucor spp. probiotic, while alteration of the bursa was observed at 42 days in two animals. Inclusion of probiotic Rhizomucor spp. in the diet of broilers promoted an increase in the height of the villi after 21 days, and any influence of the probiotic was resolved after 42 days of age.

“…Therefore, the amount of nutrients needed for enterocyte repair and the rates of nutrient digestion and absorption remained similar. Bueno et al (2012) observed a significant (P <0.05) interaction in probiotic treatment and bird age compared with unsupplemented control birds. In Japanese quail, supplementation with probiotics increased crypt depth at 7 days old but reduced it at 35 days old.…”

This study evaluated the performance, immune response to vaccination, digestive organs, intestinal histomorphometry, and microbiological development in the diet and litter of Isa Brown strains at growing receiving phase alternative additives in the place of antibiotics. Four treatments were arrayed in a completely randomized design: T1) Basal diet without antibiotics, T2) Basal diet with antibiotics, T3) Basal diet with probiotics, and T4) Basal diet without antibiotics and water modified by a photoelectron generator. There were six replications of eight birds each and thus a total of 192 birds. Performance was evaluated for eight weeks and during this period blood samples were collected at 9, 12 and 15 weeks of age for serological evaluation. At the end of the experimental period, 24 birds were euthanized, collecting the intestinal tract and later performing histomorphometry. Microbiological analyses were performed in the experimental diets and in the material of the litter of the boxes. The results obtained were analyzed by analysis of variance and the contrast between treatment means when significant by Tukey’s test. The results indicate that the replacement of antibiotics with T3 or T4 did not interfere negatively (P >0.05) in the performance of the birds, immunological response, viscera analyses and intestinal histomorphometry. In addition, use of T3 and T4 might lead to more rapid decomposition of excreta and reduce antibiotic residue in the soil when the litter is used in crop production.Keywords: dileka, Gallus domesticus, histomorphometry, laying hens, probiotics, serum biochemistry, water

“…Moreover, herbal medicines (propolis), probiotics, symbiotics and organic acids are classi ed as performance-enhancing additives (Brasil, 2004) and it is notorious how these additives cannot express positive results due to the lack of sanitary challenge in poultry studies, in different experimental variables (Silva et al 2012;Bueno et al 2012;Bastos-Leite et al 2016). Because, good prophylactic conditions for raising animals and a minimum of stress (which is usually associated with nutritional, environmental or behavioral factors), do not present a su cient increase in bacteria to cause an imbalance in intestinal health, compromising productive performance (Fukayama et al 2005).…”

This study aimed to determine the effects of aqueous extract of red propolis (RP) as an alternative to synthetic antimicrobial for quails enhanced egg quality and maintained health status. A total of 120 laying quails with 52 days of age were were randomly allotted to dietary treatments and six replicates of five birds each in completely randomized design. There were four dietary treatments as following: Control (TC), with enramycin (TE), 1g RP/kg of feed (RP1), 2g RP/kg of feed (RP2) in concetrated diet raised for 63 days. The results of productive performance such as percentage of egg production, feed intake per quail per day, average egg weight, egg mass, foods conversions showed no significant difference between treatments. The quails fed with red propolis in fresh eggs showed darker yolk (P < 0.05), with higher intensity of red and lower intensity of yellow; as less than 6.0 pH yolk; microbiological characteristics analyzed on the surface of eggs and feces of quails was lower and less than compared with other treatments. It is possible to conclude that red propolis showed promising results to be used as a feed additive for laying quails, since it maintained the productive performance of these animals and caused qualitative improvements in the physicochemical and microbiological characteristics of the eggs.
