Performance and development of gastric compartments of calves fed with cheese whey and transition milk / Desempenho e desenvolvimento dos compartimentos gástricos de bezerros alimentados com soro de queijo e leite de transição

ABSTRACT: This study aimed to evaluate whether cheese whey associated with transitional milk or not, could serve as a suitable alternative to whole milk for calf rearing. For this, twenty-four male calves of crossbred Holstein-Zebu, were distributed in a completely randomized design with three treatments (8 calves per treatment) and fed for 60 days with one of the following liquid diets: i) 100% whole milk, ii) 50% whole milk and 50% cheese whey, and iii) 30% transitional milk and 70% cheese whey. There was no difference in food intake between treatments. The analysis showed that whole milk replacement did not alter the stomach weight or the ruminal cell proliferation when compared to treatment using 100% whole milk; however, the transitional milk/cheese whey group showed larger ruminal papillae. These results suggested that a transitional milk-cheese whey diet associated with solid food and proper nutrient complements might enhance the post-natal development of rumen papillae in calves, which might contribute to prepare them for weaning.

RESUMO: Objetivou-se avaliar se o soro de queijo associado ou não ao leite de transição poderia servir como uma alternativa adequada ao leite integral para a criação de bezerros. Para isso, 24 bezerros machos, mestiços Holandês-Zebu, foram distribuídos em delineamento inteiramente casualizado com três tratamentos (oito bezerros por tratamento) e alimentados por 60 dias com uma das seguintes dietas líquidas: i) 100% leite integral; ii) 50% de leite integral e 50% de soro de queijo, e iii) 30% de leite de transição e 70% de soro de queijo. Não houve diferença na ingestão de alimentos entre os tratamentos. A análise mostrou que a substituição do leite integral não alterou o peso do estômago ou a proliferação das células ruminais quando comparado ao tratamento com 100% de leite integral. No entanto, o grupo de soro de queijo/leite de transição mostrou papilas ruminais maiores. Esses resultados sugerem que uma dieta de soro de queijo com leite de transição associada a alimentos sólidos e a complementos nutricionais apropriados pode aumentar o desenvolvimento pós-natal de papilas no rúmen de bezerros, o que pode contribuir para prepará-los para o desmame.

A Meta analysis on Rehabilitation effect of early non-liquid diet in patients with mild acute pancreatitis / 中国实用护理杂志

Objective To evaluate the effect of early non-liquid diet for patients with mild acute pancreatitis by using Meta-analysis. Methods The randomized controlled trials(RCT) on early non-liquid diet intake for patients with mild acute pancreatitis were collected by computer searching the database of China National Knowledge Infrastructure(CNKI),Wanfang Periodical Database,CBM,Elsevier Scien Direct, cochrane library and PubMed from inception to February 2017, and analyzed by RevMan 5.2 software. Results Five RCTs were included in the study.The Results of Meta-analysis revealed that both the length of hospitalization after eating [MD=-1.48,95%CI-2.50~-0.47, P=0.004] and the total length of hospitalization[MD=-1.99,95%CI-(0.99-2.99),P=0.0001]in liquid diet group were less than that of non-liquid diet group,and the differences were statistically significant.There was no significant difference in the rate of the pain recurrence[RR=1.21,95%CI 0.77-1.91,P=0.40]and the rate of the elimination of oral feeding[RR=1.02,95%CI 0.45-2.30,P=0.96]because of pain,nausea or vomiting after refeeding,although all that rate in non-liquid diet was not lower than that of liquid diet group. Conclusions compared with liquid diet,early non-liquid diet intake for mild acute pancreatitis can shorten their hospitalization time, and it cannot be concluded that the non-liquid diet will increase the pain recurrence rate, and most patients have a better tolerance to non-liquid diet,and non-liquid diet can promote rehabilitation.

Comparison of two mouse models of alcoholic liver disease induced by oral ethanol gavage or Lierber-DeCarli ethanol liquid diet / 中国比较医学杂志

Objective To select a simple, stable and reliable mouse model of alcoholic liver disease. Methods The mouse models of alcoholic liver disease were induced by oral gavage ethanol or Lierber?DeCarli ethanol liquid diet for 8 weeks. The food intake and body weight were recorded. Pathological changes were examined using HE staining. Liver injury was assessed by the activities of serum ALT, AST, AKP and γ?GT, and serum and hepatic TC and TG. Results After modeling, both models showed significantly increased activities of serum ALT, AST, AKP, and contents of serum and hepatic TG (P<0?05), indicating the successful development of alcoholic steatohepatitis. However, oral ethanol gavage led to body weight loss and weak mental state. Ethanol liquid diet less affected the body weight and mental state. Ethanol liquid diet enhanced liver to?body weight ratio and serum TC, but oral gavage of ethanol did not. The changes of serum ALT, AST, serum and hepatic TG, and hepatic steatosis in the ethanol liquid diet models were more severe than those in the oral gavage ethanol models, suggesting that Lierber?DeCarli ethanol liquid diet led to more serious liver injury than oral gavage ethanol. Conclusions Lierber?DeCarli ethanol liquid diet model is better than oral gavage ethanol model, and is more suitable for studies on mechanisms and evaluation of hepato?protective drugs for alcoholic liver disease.

Desempenho e parâmetros sanguíneos de bezerros leiteiros que receberam sucedâneo lácteo ou silagem de colostro / Performance and plasma metabolites of dairy calves fed a milk replacer or colostrum silage

O objetivo deste estudo foi avaliar o desempenho e os parâmetros sanguíneos de bezerros que consumiram colostro bovino fermentado sob condições anaeróbias. Após o nascimento, 18 bezerros da raça Holandês foram alojados em abrigos individuais e passaram a receber 4L da dieta líquida, sucedâneo lácteo ou silagem de colostro, divididos em duas refeições. O consumo de concentrado inicial e o escore fecal foram registrados diariamente, enquanto a pesagem e as colheitas de amostras de sangue para a determinação das concentrações plasmáticas de glicose, nitrogênio ureico, ácidos graxos livres, β-hidroxibutirato e proteínas totais séricas foram realizadas semanalmente. Os animais alimentados com silagem de colostro apresentaram menores consumo de concentrado, ganho de peso diário e peso vivo. Todos os parâmetros sanguíneos avaliados foram afetados pelos tratamentos, exceto a concentração plasmática de proteínas totais. O escore fecal foi afetado pelos tratamentos durante a segunda semana de vida, com animais alimentados com silagem de colostro apresentando fezes anormais e secas. O fornecimento de silagem de colostro como dieta líquida exclusiva não resultou em desempenho animal adequado, não sendo uma boa alternativa de substituto de leite.

The aim of this study was to evaluate the performance and plasma metabolites of calves fed colostrum fermented under anaerobic conditions as an exclusive liquid feed during the whole milk-feeding period. After birth, eighteen Holstein male calves were housed in individual hutches and fed four liters of liquid diet, milk replacer or colostrum silage, divided into two meals. The starter feed intake and fecal scores were recorded daily, and body weight and blood samples for the determination of plasma glucose, urea nitrogen, free fatty acids, β-hydroxybutyrate and serum total protein were taken weekly. Animals fed colostrum silage had lower intake of starter feed during the experimental period. Significant effects were also observed for average daily gain and body weight. All blood parameters measured were affected by the treatments, except the total protein plasma concentration. The fecal score was affected by treatments during the second week of life, with animals fed colostrum silage presenting abnormal and very dry feces. Feeding colostrum silage as exclusive liquid diet during the whole milk-feeding period resulted in inadequate animal performance, being considered a bad alternative as milk replacer.

A Clear Liquid Diet Is Not Mandatory for Polyethylene Glycol-Based Bowel Preparation for Afternoon Colonoscopy in Healthy Outpatients

BACKGROUND/AIMS: A dietary regimen consisting of a clear liquid diet (CLD) for at least 24 hours is recommended for colonoscopy preparation. However, this requirement results in problems in patient compliance with bowel preparation. The aim of this study was to evaluate the efficacy of a CLD compared with a regular diet (RD) for colonoscopy preparation using a polyethylene glycol (PEG) solution. METHODS: This was a multicenter, randomized, investigator-blind prospective study. A total of 801 healthy outpatients undergoing afternoon colonoscopy were randomized to either a CLD or RD in addition to a 4 L PEG regimen. RESULTS: The quality of bowel cleansing was not different between the CLD and RD groups in terms of the proportion with excellent or good preparation. In addition, no significant differences were observed between the two groups for polyp and adenoma detection rates and overall adverse events. Good compliance with bowel preparation was higher in the RD group than in the CLD group. CONCLUSIONS: A CLD for a full day prior to colonoscopy should not be mandatory for PEG-based bowel preparation. Dietary education concerning the avoidance of high-fiber foods for 3 days before colonoscopy is sufficient, at least for healthy outpatients.

Gastric Mucosal Injury after Ingestion of a Hot Liquid Diet via Gastric Feeding Tube / 대한소화기내시경학회지

When a patient complains of gastrointestinal symptoms such as nausea, vomiting, and upper abdominal pain after ingestion of a substance such as a corrosive agent and certain drugs which can cause mucosal injury to the esophagus and stomach, we always keep in mind gastrointestinal injury and should perform an endoscopic procedure promptly and use the appropriate treatment. It is well known that common corrosive agents which can cause gastrointestinal injury are acidic and alkaline chemicals, and the common causative drug for gastrointestinal injury is NSAID. However, it is not well known that consuming hot food and drinks can cause gastrointestinal injury also. Up to now, there have only been a few case reports of esophageal mucosal injury due to the consumption of hot food and drinks. Gastric mucosal injury after ingesting hot food and drinks is rare and has not been reported often. So here, we report a case of gastric mucosal injury after ingesting a hot liquid diet via gastric feeding tube.

Use of polyester pad as a new physical substrate for rearing Cochliomyia hominivorax coquerel (Diptera: Calliphoridae) larvae / Uso de manta de poliéster como substrato novo para criação de larvas de Cochliomyia hominivorax coquerel (Diptera: Calliphoridae)

Polyester pad was utilized as solid support for rearing Cochliomyia hominivorax Coquerel larvae in liquid diet and compared with the ground meat diet. There were no significant differences in the mean third instar larvae and pupal weights, number of pupae, emergence and rearing efficiency. The tests were conducted through four consecutive generations, presenting no detectable effect in any of the life history parameters. We propose that the polyester pad can be used as solid support for rearing C. hominivorax larvae in liquid diets and can be reutilized reducing the costs of mass rearing.

A utilização de manta de poliéster como substrato para a criação de larvas de Cochliomyia hominivorax Coquerel em dieta líquida foi comparada com dieta à base de carne moída. Não foram verificadas diferenças na média dos pesos de larvas de terceiro estágio e pupas, número de pupas formadas, emergência e eficiência de criação. Os resultados foram obtidos por quatro gerações consecutivas, não demonstrando interferência em nenhum parâmetro biológico avaliado. Propõe-se que manta de poliéster pode ser utilizada como suporte para a criação laboratorial de C. hominivorax em dieta líquida, reduzindo os custos de criação, uma vez que pode ser reutilizada.
