Farelo de gérmen de milho desengordurado na dieta de poedeiras comerciais de 28 a 44 semanas de idade Defatted corn germ meal in diets for laying hens from 28 to 44 weeks of age

Um experimento foi conduzido para avaliar os efeitos da inclusão de farelo de gérmen de milho desengordurado na dieta de galinhas de 28 a 44 semanas de idade. Foram utilizadas 240 poedeiras Hy-Line W36 distribuídas em delineamento inteiramente casualizado, com seis níveis de farelo de germen de milho desengordurado (0, 6, 12, 18, 24 e 30%),cada um com cinco repetições de oito aves. No período experimental, que durou quatro ciclos de 28 dias, foram avaliados os parâmetros de desempenho das aves (consumo de ração, produção de ovos, peso médio do ovo, massa de ovo e conversão alimentar) e de qualidade dos ovos (gravidade específica, índice de pigmentação da gema, porcentagem de gema e albúmen, porcentagem e espessura da casca e unidade haugh). Os níveis de farelo de gérmen de milho desengordurado tiveram efeito linear negativo sobre o consumo de ração e o índice de pigmentação da gema e efeito quadrático sobre a conversão alimentar. A inclusão de farelo de gérmen de milho desengordurado na dieta não influenciou as outras variáveis estudadas. O farelo de gérmen de milho desengordurado pode ser incluído em níveis de até 21,2% em rações para galinhas poedeiras.<br>This experiment was conducted to evaluate the effect of including defatted corn germ meal in diets for laying hens. It was assigned two hundred and forty laying hens to a randomized design, with six diets and five replicates of eight hens per diet. Experimental diets were formulated by inclusion of defatted corn germ meal at 0, 6, 12, 18, 24 and 30% level. The period experiment was carried out for four 28-day cycles and performance (feed intake, egg production, egg weight, egg mass and feed conversion) and the egg quality (egg specific gravity, yolk color, yolk and albumen percentages, shell percentages, shell thickness and Haugh unity) were the evaluated parameters. Negative linear effect was observed for feed intake and yolk pigmentation by increasingly including defatted corn germ meal in diets for laying hens. Quadratic effect of defatted corn germ meal for feed conversion was also observed. No statistical differences were observed for any other parameters. Defatted corn germ meal can be included at 21.2% in laying hens diets

Desempenho e qualidade dos ovos de poedeiras semipesadas alimentadas com dietas contendo óleos de soja e canola Performance and eggs quality in laying hens fed diets with soybean and canola oils

Objetivou-se analisar a influência da adição de níveis crescentes de óleo de soja e canola sobre os índices de desempenho e qualidade interna e externa dos ovos de poedeiras comerciais semipesadas da linhagem Bovans Goldline durante cinco períodos de 28 dias. Foram utilizadas 280 aves com 18 semanas de idade, em um delineamento inteiramente casualizado, com sete tratamentos em um esquema fatorial 2 × 3 + 1 (dois tipos de óleo e três níveis de óleo mais um testemunha adicional) com cinco repetições e oito aves por unidade experimental. Os níveis de óleo de soja e de canola não alteraram o consumo de ração, os pesos dos ovos, de albúmen, de gema e de casca, as porcentagens de albúmen, de gema e de casca e a gravidade específica dos ovos. Houve influência significativa da interação tipo × nível de óleo sobre a produção de ovos e a conversão por massa e por dúzia de ovos. Com o aumento do nível de óleo de soja, os resultados obtidos para estas variáveis melhoraram, entretanto, a conversão por massa de ovo piorou com o aumento dos níveis de óleo de canola. A adição de óleo de soja promoveu desempenho melhor que o obtido com óleo de canola.<br>The objective of this study was to evaluate the influence of soybean and canola oil added in crescent levels on production performance indexes and internal and external egg quality of brown commercial layers of the strain Bovans Goldline during five periods of 28 days. Two hundred and eighty hens with 18 weeks old were distributed in a completely randomized design, with seven diets in a 2 × 3 + 1 factorial arrangement (oil type and oil level, and an additional control), with 5 replicates of 8 hens per experimental unit. The soybean and canola oil levels did not affect the feed consumption; egg, albumen, yolk and shell weights; albumen, yolk and shell percentages, neither the specific gravity. There was an interaction between type and oils levels on egg production and mass conversion and per egg dozen. Better results for those characteristics were obtained as soybean oil increased. However, the egg mass conversion was negatively influenced by increase of canola oil. The addition of soybean oil promoted better performance as compared to canola oil

International Nosocomial Infection Control Consortium report, data summary of 50 countries for 2010-2015: Device-associated module

•We report INICC device-associated module data of 50 countries from 2010-2015.•We collected prospective data from 861,284 patients in 703 ICUs for 3,506,562 days.•DA-HAI rates and bacterial resistance were higher in the INICC ICUs than in CDC-NHSN's.•Device utilization ratio in the INICC ICUs was similar to CDC-NHSN's. Background: We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. Methods: During the 6-year study period, using Centers for Disease Control and Prevention National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregate of 3,506,562 days. Results: Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8 per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associated pneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples, frequencies of resistance of Pseudomonas isolates to amikacin (29.87% vs 10%) and to imipenem (44.3% vs 26.1%), and of Klebsiella pneumoniae isolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27% vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs. Conclusions: Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported in CDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the reduction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICC's main goal to continue facilitating education, training, and basic and cost-effective tools and resources, such as standardized forms and an online platform, to tackle this problem effectively and systematically
