title: Effects of the Inclusion of Dietary Organic Acid Supplementation with Anti-Coccidium Vaccine on Growth Performance, Digestibility, Fecal Microbial, and Chicken Fecal Noxious Gas Emissions

description: ABSTRACT A total of 792 conventional healthy 1-day-old Ross 308 broilers chicks (mixed gender) with average body weight of 42.30±1.14 g (mean ± SD) were used in the experiment, which lasted for 35 days. Chicks were randomly allotted into one of four treatment diets, each one having 11 replicate cages with 18 birds each, being fed corn-soybean meal (SBM) based diets. Dietary treatments were CON (basal diet with unvaccinated birds); OA = CON + 0.1% organic acids; ACB = CON + anti-coccidium vaccine; OAACV = CON + 0.1% organic acid + anti-coccidium vaccine. Significant results were observed, with improved body weight (p=0.059; 0.064; 0.034) during days 1-7, 8-21, and overall, respectively. Significant effects were also observed on the feed conversion ratio (p=0.037) through the overall experiment, with no effects on feed intake on OAACV as compared to other treatment groups. Total track digestibility of dry matter (p=0.049) improved significantly in the OAACV treatment group. Additionally, beneficial effects were observed in the OAACV treatment group, with improvements in fecal microbial population (increased lactobacillus) and reduced NH3 gas emissions. Broilers fed the OAACV treatment tended to display reduced drip loss in the meat samples analyzed on days 5 and 7 (p=0.067, 0.072). In summary, our findings revealed that dietary inclusion of organic acid supplementation with anti-coccidium had a beneficial effect on broilers affected by coccidian infection, also improving growth performance, digestibility, fecal Lactobacillus counts, and reducing NH3.

title: Detection of Mycoplasma Synoviae and Other Pathogens in Laying Hens with Respiratory Signs in the Rearing and Production Phases

description: ABSTRACT The present study aimed to investigate the occurrence of Mycoplasma synoviae (MS), M. gallisepticum (MG), Ornitobacterium rhinotracheale (OR), Avibacterium paragallinarum (AP), Pasteurella multocida (PM) and Infectious Bronchitis Virus (IBV) in laying hens with respiratory clinical signs in two phases of production. 140 tracheal swabs and 140 blood samples were collected from laying hens in the rearing and production phases, the chickens belonged to six farms (A-F) located in the state of São Paulo, Brazil. The samples were analyzed by PCR for MG, MS, OR, AP, PM and IBV and by ELISA for MG and MS. The highest frequencies observed by PCR were for MS at farms B and C with 95 and 100% positivity, followed by MG at farms D and E with 35% and 65%, IBV with 35% at farm F and ORT with 15% at farm A. All flocks were positive for MG and MS in serology. Although MG and IBV have been detected, this can be explained by the vaccination protocols, since live attenuated vaccines are widely used for immunization against these pathogens. It was also possible to detect OR and AP thorugh PCR in some flocks. The occurrence of several etiological agents that cause respiratory diseases in laying hens was confirmed by PCR and serology, with MS being the most prevalent and being present in all farms studied.

title: Levels of Polyamines in Feces of Laying Hens Fed with Agave Fructans (Agave Tequilana, Weber) in Association with the Quality and Production of Egg

description: ABSTRACT In this study two experiments were carried out, the effect of a diet supplemented with fructans of Agave tequilana Weber, was analyzed in Hy-line hens in regards to their egg quality and production as well as on the levels of the polyamines, putrescine, spermidine and spermine in their feces. In the first study 300 Hy-line W-36 hens per group, which were aged 36 weeks, were randomly separated as follows for each of the three treatments. One group of 100 hens was fed with a diet supplemented with 0.1% fructans. Another group of 100 hens was supplemented with 0.2% fructans and a group of 100 hens without any fructans was added as a control group. Feed consumption was lower in the supplemented groups compared to the control group (p&lt;0.05). Egg yolk quality was measured using Haugh units. The quality of the shell was studied using an Egg Force reader (g pressure/mm2). Putrescine levels was measured in 10 animals in each group. In the second study, 1,155 laying hens, aged one day from the Hy-line W-35 genetic line were also randomly divided into three groups containing 385 hens in each one (A, B, C). Egg laying levels and weight was measured during 35 weeks. The egg laying percentage increased considerably in hens ingesting supplemented diets (p&lt;0.05) and the egg weight was greater mainly in the supplementation with 0.1% fructans (p&lt;0.05). Thus, it was shown that diet supplementation with fructans of agave improves egg quality and homeostasis and food consumption in the Hy-line hen.

title: Effect of Essential Oil and Organic Acid on Performance, Gut Health, Bacterial Count and Serological Parameters in Broiler

description: ABSTRACT A total of 1500 day old broiler chicks were grouped into five treatments; each treatment group further consisted of six replicates. Group A was given a control diet having antibiotics. Group B and C were offered essential oil blend at the proportion of 0.1 g/kg and organic acid at the dose rate of 1g/kg. Group D was given both essential oil 0.1 g/kg and organic acid 1g/kg in combination. Group E was offered only a basal diet without antibiotics and considered as a negative control. The trial lasted for 35 days. Results indicated that the body weight gain and feed conversion ratio (FCR) exhibited significant improvement but insignificant in the case of feed consumption. Bodyweight and FCR were better in group B, followed by C. Carcass characteristics like eviscerated weight and giblet weight were also improved in group B while dressed weight showed insignificant results. Total cholesterol and high-density lipoproteins (HDL) were unaffected by the treatments; however, increased blood glucose levels and decreased low-density lipoproteins (LDL) concentration were significantly noticed. Treatment groups have no effect on antibody titer against ND at the end of the trial. In gut morphology, significantly higher villus height was observed in group C, but villus width and crypt depth remained unaffected. In conclusion, essential oil and organic acids have improved performance, carcass parameters, serum biochemistry, gut health, and decreased bacterial count.

title: SH151165.07FU

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.
