The Effects of Dietary Omega 3 Fatty Acids on Commercial Broiler Behavior from Hatch to Market Weight

The objective of this experiment was to investigate how different dietary omega-3 sources affect commercial broiler behavior from hatch to market weight. One hundred and twenty male 308 Ross broiler chicks were enrolled into the study. Three dietary treatments were compared; Control, Flaxseed-and Fish-oil. Fifteen pens were randomly selected and onefocal-bird was watched continually for three periods of time. One behavior, two postures,and an unknown category were collected. Week by dietary treatment interaction was not significant for any broiler behaviors (P ≥ 0.49). There was no dietary treatment effect observed for any broiler behaviors (P≥ 0.32). There was no observed difference for percentage of time spent at the feeder between week 1 and 4 (P =0.14). However, there was a difference for percentage of time spent active (P \u3c 0.0001), inactive (P = 0.0004) and unknown (P = 0.01) between week 1 and 4. Within the context of this work, the selected omega-3 dietary sources did not affect broiler behavior between weeks 1 and 4. Independent of dietary treatment, broilers increased the percentage of time spent inactive by week 4 of the study

The Effects of Dietary Omega 3 Fatty Acids on Commercial Broiler Lameness and Bone Integrity from Hatching to Market

The objective of this experiment was to investigate how different dietary ω-3 sources affect lameness and bone integrity of commercial broiler chickens from hatching to finishing.One hundred and twenty male Ross308broiler chicks were assigned to three dietary treatments; control, flaxseed oil and fish oil for 4 consecutive weeks. From week 1 to 4, broilers were visually assigned a lameness score (2 non-lame to 5 non-ambulatory) anda bone integrity score (score 2 normal bones to 5 bird was non-ambulatory and was removed from the trial).There were no observed differences for the dietary treatmentand week interaction for lameness or bone integrity (P= 1.00). There wasno observed lameness or bone integrity differences (P≥0.93) between dietary treatments. There were no observed differences for lameness (P= 0.92) and bone integrity differences(P= 1.00) over the four consecutive weeks. In conclusion, regardless of dietary treatment, birds in this study were not lame and had normal bone integrity

CONTRIBUIÇÃO DE EDUCAÇÃO PERMANENTE SEMIPRESENCIAL NO CONHECIMENTO DE ENFERMEIROS SOBRE ESTOMIAS INTESTINAIS DE ELIMINAÇÃO

RESUMO Objetivo: avaliar a contribuição de um programa de educação permanente semipresencial no conhecimento de enfermeiros sobre estomias intestinais de eliminação. Método: estudo quase-experimental, do tipo grupo único, antes e depois, realizado com 51 enfermeiros de três hospitais de grande porte do Piauí, no período de agosto a outubro de 2014, nas seguintes etapas: identificação dos enfermeiros, exposição dos objetivos e convite para participação na pesquisa, pré-teste, programa de educação permanente semipresencial e pós-teste. Resultados: a média do número de acertos dos enfermeiros no pré-teste 25,5 (dp=4,2) foi menor do que no pós-teste 31,5 (dp=3,0) e essa diferença foi estatisticamente significante (p=0,000). Conclusão: neste estudo, o programa de educação permanente semipresencial contribuiu para melhorar o conhecimento dos enfermeiros sobre estomias intestinais de eliminação

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
