“…These results indicate that kefir may improve carcass hygiene by influencing the microbial balance in intestine (Yaman et al, 2006) but has no effect on body measurements. Similarly, Yenice et al (2014) reported no significant increase in heart weight, but contrary to our results, they showed an increase in live and gizzard weight in kefir-supplemented groups. In our study, there was no significant increase or decrease in spleen and bursa weights, which might be related to feed intake, which remained unchanged in the kefir-treated groups.…”

Non-ruminants Full-length research article Effects of dietary supplementation of kefir on body measurements, weight of visceral organs, and gut morphology in geese ABSTRACT-This study was designed to evaluate the effects of adding kefir on body measurements, giblet weight, and gut morphological patterns of geese through drinking water. A total of 54 birds were divided into three groups, each comprising 18 birds, and each group was further divided into three subgroups containing six birds each. One group served as the control group, while the other two groups were given kefirtreated drinking water at the ratios of 2.5 and 7.5%, respectively. No significant effects of kefir supplementation on body measurements, spleen weight, bursa weight, and gut morphology were observed. It is concluded that kefir may be used in poultry feed with an inclusion rate of 7.5% without imposing any adverse effect on the measurements of body structures, weights of visceral organs, and gut morphology.

“…After the fixation, the tissues were subjected to alcohol, xylene and paraffin blocks, respectively. Subsequently, they were cut at 5 µm thickness of sections by microtome, glued to slides and examined under light microscope (Olympus BX51, Tokyo, Japan), after stained with Haematoxylin-Eosin (HE) [12] .…”

In this study, naturally infected by Gallid Herpesvirus type-1 in laying hens to be diagnosed by pathological and PCR methods. Sixty pieces of hens were collected in coops from Central Anatolia region. After necropsy, routine pathological processes were applied to the trachea/ larynx, sinuses, lungs and air sacs. All organs were also stained by immunoperoxidase method, and PCR methods were applied to formalin fixed paraffin embedded (FFPE) tissues. Immunohistochemically, the positivities were seen in trachea/larynx (78.3%), sinuses (61.6%), lungs (45%) and air sacs (50%). Positive reactions were observed, in mucous and gland epithelia especially located at intracytoplasmic and rarely intranuclear. PCR positivity was observed in the trachea/larynx in 15 (25%) cases, in infraorbital sinus in 11 (18.3%) cases, in lungs in 8 (13.3%) cases and in air sacs in 6 (10%) cases following the tests performed. Following these results, it is easily concluded that histopathology and immunoperoxidase method can usable for diagnosing of the ILT. However, PCR results made by FFPE tissues showed that this method is not adequate to diagnose the ILT alone.

Bu amaçla Orta Anadolu'da bulunan bazı illerdeki kümeslerden toplam 60 adet enfekte tavuk toplandı. Yapılan nekropsilerin sonrasında trake, larinks, infraorbital sinus, akciğer ve hava kesesi parçaları alınarak rutin patolojik işlemler uygulandı. Alınan tüm organlar ayrıca indirekt immunperoksidaz yöntemi ile boyandı ve organlara ait formolle fikse edilmiş parafine gömülü (FFPG) dokulara PZR testi yapıldı. İmmunohistokimyasal boyamalar sonucu trake/larinkste %78.3, sinuslarda %61.6, akciğerlerde %45 ve hava keselerinde %50 oranında pozitiflik gözlendi. Pozitif boyanmalar özellikle mukoza ve bez epitellerinde intrasitoplazmik nadiren de intranüklear olarak gözlendi. Aynı zamanda lümene dökülmüş eksudattaki hücre ve sinsityal dev hücrelerinin sitoplazmalarında da boyanmalar tipikti. Yapılan PCR testlerinin ardından trake/larinkste %25, infraorbital sinuslarda %18.3, akciğerlerde %13.3, hava keselerinde %10 oranında pozitiflik gözlendi. Bu sonuçların ardından hastalığın teşhisinde histopatolojik ve immunperoksidaz yönteminin rahatlıkla kullanılabileceği ortaya konmuştur. Ancak, FFPG dokulardan yapılan PCR yönteminin tek başına İLT'yi teşhis etmek için yeterli olmadığı gösterildi.

“…Cenesiz et al, (2008) reported that fermented dairy products (kefir, yogurt) works like commercial probiotics, dietary kefir supplementation increased growth of broilers and also, Boostani et al, (2013) reported that dietary yogurt supplementation increased growth performance. General effects of these dairy fermented food additives is that they increases growth of chicks (Boostani et al, 2013;Cenesiz et al, 2008;Karademir and Unal, 2009;Yaman et al, 2006) by increasing gut health (Yaman et al, 2006;Yenice et al, 2014). Fermented dairy products are functional foods for human nutrition, determined that they work like probiotic in the body.…”

The aim of this study was to determine the effect of dietary cereal based fermented functional food (CBFFF) supplementation on growth performance, duodenum histomorphology, internal organ development and cecum microflora of quails. In this study, a total of 100 mixed sex birds at 21 age of days were used as animal material. The birds were divided into 2 dietary groups as control (C) and 5 g/kg CBFFF supplementation (F) with 5 replicates (5 male average 64.33±0.32g and 5 female average 66.42±0.38g for each replicate. The experiment lasted 21 days. Live weight gain (LWG), feed intake (FI), and feed conversion ratio (FCR) determined weekly. At the end of the experiment, one female and one male bird were selected from each replicate (a total number of 20 quails) and their characteristics of cecum microbiota and duodenum histomorphology were determined. LWG, FI, FCR, inner organs, did not change among the groups. Lactic acid bacteria (LAB) and yeast count was tend to increase, Enterobactericaea was tend to decrease. E coli and Coliforms count in cecum decreased statistically. Villi length increased in F group than in the C group. To conclude, CBFFF decreased pathogenic bacteria in cecum and developed intestinal microflora and increased the digestion surface area in duodenum. Therefore, it can be said that 5 g/kg dietary CBFFF can use to improve cecum microflora and duodenum histomorphology in quails. But further studies should be conducted to determine probiotics effects of CBFFF on other animal species, doses or stress factors such as feed restriction, high fiber or low protein in diet etc.
