“…There have been many studies on the effect of DF concentrations on broiler performance, but fail to be consistent across studies. Sadeghi, Toghyani, and Gheisari () observed that 30 g/kg DF sources from sugar beet pulp and rice hulls in the diet reduced daily weight gain in broiler chicks from 1 to 14 days. Conversely, diets containing 3% oat hulls increased body weight gain or ADG in broiler (Jiménezmoreno, Gonzálezalvarado, Gonzálezserrano, Lázaro, & Mateos, ; Mateos, Jimenezmoreno, Serrano, & Lázaro, ), and even 2.5%–5% DF in the diet had no significant effect on ADG in young broiler.…”

This study investigated the effect of dietary fibre (DF) supplementation on hepatic fat deposition of Cherry Valley meat ducks. A total of 600 1-d-old ducks were randomly allotted to five dietary fibre diets (1.46 (basal diet), 3.09, 4.15, 6.18 and 7.52% (analysed)) for 14 days. Growth performance decreased with increasing DF concentrations, when the DF level more than 6.18% the average daily gain (ADG) and feed conversion ratio (F/G) markedly decreased in meat ducks. Meat ducks supplemented over 4.15% DF had lower percentage of liver reported to live weight, liver lipid contents, hepatic triglyceride and total cholesterol concentrations as well as decreased serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentrations at 14 days. The transcription of fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC) and sterol-regulatory element-binding protein-1 (SREBP-1) in liver was significantly reduced by DF, while no any significant difference was found about the effect of DF on hepatic peroxisome proliferator-activated receptor α (PPARα), adipose triglyceride lipase (ATGL), transcription as well as caecal digesta short-chain fatty acids (SCFA). Data suggested that dietary fibre supplementation decreased hepatic lipid deposition and improved characteristics of liver health via inhibiting hepatic FAS, ACC and SREBP-1 expression in meat ducks.

“…Probably, the combined effect of lighter BW at the onset of egg production and reduced ADFI early in the egg cycle resulted in lower egg production in these pullets (Leeson et al, 1997;Pérez-Bonilla et al, 2012a In this respect, Almirall et al (1997) reported a reduction in egg production in hens fed a cereal-soybean meal diet diluted with 7.5 or 15.0% SBP, although in this research all hens received a common feeding program during the rearing phase. Similar reduction in BWG and feed efficiency has been reported in broilers by González-Alvarado et al (2010) and Sadeghi et al (2015) with the inclusion of 3% SBP in the diet. Sadeghi et al (2015) reported also an increase in intestinal viscosity and a reduction in villus height of the duodenum and ileum mucosa when 3% SBP was included in the diet.…”

Agradecimientos¡Y yo que pensaba que esto era la parte fácil de la tesis! No paran de venirme a la cabeza nombres de personas a las que tengo algo que agradecer por haberme ayudado de una manera u otra durante estos cuatro años y medio.Si estás leyendo esto y no encuentras tu nombre, pero crees que debería estar, perdóname, sois tantos que no es difícil que alguno se me escape. Creéme si digo que te lo agradezco de corazón.En primer lugar, porque seguramente sean los primeros en leer estas líneas, me gustaría agradecer a todos y cada uno de los miembros del tribunal que han aceptado evaluar esta tesis y estar presentes el día de mi defensa. Gracias por buscar un hueco en vuestras apretadísimas agendas y ayudarme en este momento tan importante.A los doctores Hans Stein y Edgar García Manzanilla, por aceptarme en sus respectivos grupos. Nunca olvidaré la conjuntivitis que cogí en Estados Unidos por limpiar la nave con agua a presión con las lentillas puestas, ni tampoco el miedo que llevaba en el cuerpo cada vez que conducía por las maravillosas carreteras irlandesas.Bromas aparte, gracias a los dos por permitirme vivir dos de las mejores experiencias de mi vida.A todos los profesores del departamento que de una manera u otra me han ayudado a lo largo de estos años. Ya sea porque he tenido la suerte de ser su alumna durante el desarrollo del máster o porque me han recibido con una sonrisa cada vez que me surgía alguna duda y acudía a ellos. La primera a Rosa Carabaño, que para algo es la jefa, gracias por preocuparte de que todo se haga como tiene que hacerse y por procurar el bienestar de los becarios precarios. A Carlos de Blas, por no tirarme algo a la cabeza cada vez que acudía a él a preguntarle las mismas dudas de estadística. Nos costó mucho hacer entender a Gonzalo que con un control había que hacer un Dunnett y no el Index of contents 4 "general model". A Mª Jesús Villamide, Javier García y Nuria Nicodemus, porque gracias a ellos me sé de memoria cómo funcionan las naves de los Campos de Prácticas y cómo se hacen la mayoría de los análisis de laboratorio. A María Alvir, por tener siempre una sonrisa en la cara, así da gusto empezar los lunes. A Javier González, por amenizarnos los cafés con sus historietas. A David Menoyo, por su paciencia y ayuda con las siembras y conteos microbiológicos, después de dos años conseguimos terminar de contar. A Rosa Lázaro, por sus consejos durante más de 4 años y porque gracias a ti sé lo que es el Brill y tengo a quién acudir cuando me dé cuenta de que realmente no sé usarlo. A todos vosotros, un millón de gracias.A Carlos Rodríguez, por la infinita paciencia que tiene con todos los que vamos a llamar a su puerta. Sabes que si tú no estuvieras el departamento sería un caos. ¿Quién si no le enchufaría el teclado a Gonzalo cuándo tuviera una crisis histérica porque el ordenador no funciona?A Andrés, por su ayuda en el laboratorio en innumerables ocasiones. ¿Cuántas horas de sueño de más llevaremos en el cuerpo porque Andrés estaba a las 7 de la mañana en el laboratorio hac...

BackgroundEnzyme supplementation and the inclusion of fibre in the barley‐based diets have been some of the alternatives proposed to improve productivity in the absence of growth promoters.ObjectiveThis study was performed to investigate the effect of adding sunflower hulls (SFH), a multi‐enzyme carbohydrate, and feed forms (mash and pellet) on performance and some physiological parameters in broiler chickens fed barley containing diets.MethodsTreatments were two feed forms (mash vs. pelleted), and four diets consisted of a barley‐based diet (control, CTL) or test diets which contained either SFH at 30 g/kg, enzyme (ENZ; 0.2 g/kg) or combination of SFH and enzyme (SFH + ENZ).ResultsThe results showed that average daily feed intake and average daily gain were significantly increased in chickens that were fed ENZ (p < 0.05). The highest digestibility of ether extract (EE) was observed in the treatment containing SFH and SFH + ENZ (p < 0.05). The highest population of Lactobacillus spp. was observed in the treatment containing SFH (p < 0.05). The villus height and villus height to crypt depth ratios of duodenum and jejunum were significantly higher (p < 0.05) in broilers fed pellet diets compared to the mash.ConclusionIt can be concluded that pellet diets reduce digesta viscosity and harmful microorganisms (Escherichia coli), increase growth performance, and improve intestinal morphology in barley‐based diets. Moreover, SFH and ENZ had favourable effects on EE digestibility and caecal microbial population of broilers fed with barley containing diets.
