Slow-release urea in supplement fed to beef steers BABT
Gonçalves,Ana Paula; Nascimento,Carolina Fernanda Moysés do; Ferreira,Fernanda Altieri; Gomes,Rodrigo da Costa; Manella,Marcelo de Queiroz; Marino,Carolina Tobias; Demarchi,João José Assumpção de Abreu; Rodrigues,Paulo Henrique Mazza.
Replacing regular urea (RU) by slow-release urea (SRU) at two levels of non-protein nitrogen (NPN) in concentrate, offered with low-quality roughage, was evaluated in beef steers on dry matter intake (DMI), ruminal fermentation parameters, plasma urea nitrogen (PUN), total tract apparent digestibility of diets and in situ degradability of nitrogen sources. Eight ruminally cannulated steers were allocated into two 4x4 Latin squares, totalizing four treatments: 40 NPN/0 SRU: 40% of concentrate crude protein (CP) as NPN, resulting from 0% of SRU and 100% of RU; 40 NPN/50 SRU: 40% of concentrate CP as NPN, resulting from 50% of SRU and 50% of RU; 40 NPN/100 SRU: 40% of concentrate CP as NPN, resulting from 100% of SRU and 0% of RU; 80 NPN/100 SRU: 80% of...

Enhanced mucosal re-epithelialization induced by short chain fatty acids in experimental colitis BJMBR
Aguilar-Nascimento,J.E.; França-da-Silva,L.R.; de-Oliveira,A.F.; Gomes-da-Silva,M.H..
The short chain fatty acids (SCFA) are the best nutrients for the colonocytes. Glucose is poorly used as a fuel but may be transformed into SCFA by colonic bacteria. The aim of this study was to investigate the effect of SCFA or glucose on experimental colitis. Colitis was induced in 30 Wistar rats by colonic instillation of 4% acetic acid. Five days later they were randomized to receive twice a day colonic lavage containing saline (controls, N = 10), 10% hypertonic glucose (N = 10) or SCFA (N = 10) until day 8 when they were killed. At autopsy, the colon was removed and weighed and the mucosa was evaluated macro- and microscopically and stripped out for DNA assay. Data are reported as mean ± SD or median [range] as appropriate. All animals lost weight but...

Neutral detergent fibre in piglet diets: performance and gastrointestinal implications Ciência e Agrotecnologia
Nepomuceno,Rafael Carlos; Watanabe,Pedro Henrique; Freitas,Ednardo Rodrigues; Carvalho,Luiz Euquerio de; Oliveira,Emanuela Lima de; Veira,Alini Mari.
ABSTRACT The intestinal health of piglets depends on the balance between diet, microflora and mucosal integrity. Disruption of this balance can compromise the digestive functions, leading to diarrhoeal frame and decline in performance of piglets. However, the level and type of fibre can limit digestive disorders. Thirty newly weaned piglets were used to evaluate the levels of neutral detergent fibre (NDF) in diets regarding performance, pH, viscosity and concentration of short chain fatty acids of digestive contents, gastrointestinal transit time, morphology of the intestinal mucosa, weights of organs and occurrence of diarrhoea. NDF level had quadratic effect on weight gain and feed conversion ratio of piglets, estimating best results at the level of...

Evaluation of iron bioavailability in a mixture of cereals, seeds, and grains ("Human Ration") Ciênc. Tecnol. Aliment.
Enes,Bárbara Nery; Alves,Natália Elizabeth Galdino; Valdés,Samanta Thomas; Silveira,Carlos Mário Martins; Costa,Neuza Maria Brunoro; Ribeiro,Sônia Machado Rocha; Pires,Shaila Turbay; Martino,Hércia Stampini Duarte.
Iron bioavailability was evaluated in three mixtures of cereals, seeds, and grains ("Human Ration"): light, regular, and homemade provided to rats. The animals received an iron depletion diet for 21 days, followed by a repletion diet containing 12 mg·kg-1 of iron for 14 days. The hemoglobin regeneration efficiency and the relative biological value did not differ between the light mixture and control group. The iron bioavailability of the light mixture of cereals, seeds, and grains and the control group were 99.99±27.62 and 80.02±36.63, respectively, while the regular and homemade mixtures of cereals, seeds, and grains showed lower iron bioavailability, 50.12±35.53 and 66.66±15.44, respectively; the iron content of the diet with light cereal mixture light...

Staple food crops from Brazilian Biofortification Program have high protein quality and hypoglycemic action in Wistar rats Ciênc. Tecnol. Aliment.

Abstract Biofortified staple food crops have become an effective tool by which to address micronutrient deficiencies in many at-risk populations. The effect of these food crops on the micronutrient status has been evaluated, however there is no studies investigating their protein quality, neither by themselves or in a food combination. Thus, this study investigated the effect of combinations of beans and rice, target for biofortification, with high carotenoids content crops (sweet potato and pumpkin) on protein quality, intestinal function and glycemia. Eight groups were evaluated (n=6): 1) rice + Caupi bean (RCB); 2) rice + Pontal bean (RPB); 3) rice + Caupi bean + pumpkin (RCBP); 4) rice + Pontal bean + pumpkin (RPBP); 5) rice + Caupi bean + sweet potato...

Effects of Flammulinavelutipes Stem Base on Microflora and Volatile Fatty Acids In Caecum of Growing Layers under Heat Stress Condition Rev. Bras. Ciênc. Avic.
Wang,S; Mahfuz,S; Song,H.
ABSTRACT The present study was undertaken to investigate the effects of Flammulinavelutipes stem base (FVS) on growth performance, microbial flora and volatile fatty acids of growing layers under heat stress condition. A total of 72 ISA Brown hens were randomly divided into six treatments: thermoneutral temperature control group (CON), heat stress control group (HS), heat stress antibiotic group (ANT) as positive control and heat stress FVS groups (20, 40 or 60 g/kg FVS). The experimental period had a duration of 28 d (days 84-112). On day 98, daily gain average was significantly higher (p<0.05) in the FVS groups than in the HS group. The number of bands in the FVS groups were higher (p<0.05) than in the HS group on day 98. The microbial similarity...

Intake, digestibility, rumen characteristics and microbial protein synthesis efficiency in bovine and bubaline fed sugar cane silage with additives R. Bras. Zootec.
Maeda,Emilyn Midori; Zeoula,Lucia Maria; Jobim,Clóves Cabreira; Cecato,Ulysses; Rigolon,Luiz Paulo; Kazama,Ricardo; Jacobi,Guido; Carvalho,Acir Felipe Grolli.
Intake and total and ruminal digestibility, ruminal characteristics and microbial synthesis efficiency in bovine and bubaline fed sugar cane silages treated with microbial additive Lactobacillus buchneri (inoculate) and the addition of: cassava byproduct meal at 250 g/kg; soybean hulls at 250 g/kg; and urea at 33 g/kg, in natural matter were evaluated. The forage:concentrate ratio was 600:400 g/kg. Bubaline body weight (BW) was 403±49 kg and bovine BW was 492±10 kg. The experimental design consisted of two 4 × 4 Latin squares in a 4 × 2 factorial arrangement. The average DM intake did not differ between species, and the diet with urea showed lowest intake (13 g/kg BW). Among the diets, the one with soybean hulls addition increased the total digestibility...
