A REVIEW ON THE ENERGY VALUE OF SUGAR BEET PULP FOR RABBITS

Blas, Carlos de; Carabaño, R. (World Rabbit Science. ICTA. UPV, 1996)

[EN] Recent information about the energy value of sugar beet pulp (SBP) is reviewed in this papar. According to the results presentad, DE content of SBP depends on the tvpe of basál diet and the level of inclusion usad. ...
Characterization of Clostridium perfringens presence and concentration of its [alfa]-toxin in the caecal contents of fattening rabbits suffering from digestive diseases

Romero, Carlos; Nicodemus, Nuria; Jarava, Maria Luisa; Menoyo, David; Blas, Carlos de (World Rabbit Science. ICTA. UPV, 2011)

[EN] Digestive diseases are the main cause of morbidity and mortality in growing rabbits. Clostridium perfringens is a widely occurring pathogenic bacterium in enteric diseases of domestic animals and its pathogenicity ...
Composition, potential emissions and agricultural value of pig slurry from Spanish commercial farms

Antezana-Julian, Walter Orestes; Blas, Carlos de; García-Rebollar, P.; Rodríguez, C.; Beccaccia, A.; Ferrer Riera, Pablo; Cerisuelo, A.; Moset Hernández, Verónica; Estellés, F.; Cambra López, María; Calvet, S. (Springer-Verlag, 2016)

[EN] Pig slurry is a valuable fertilizer for crop production but at the same time its management may pose environmental risks. Slurry samples were collected from 77 commercial farms of four animal categories (gestating ...
DETERMINATION OF THE NUMBER OF REPLICATES REQUIRED TO DETECT A SIGNIFICANT DIFFERENCE BETWEEN TWO MEANS IN RABBIT TRAITS

García, J.; Nicomedus, N.; Carabaño, R.; Villamide, M.J.; Blas, Carlos de (World Rabbit Science. ICTA. UPV, 2001)

[EN] The number of replicates required to detect differences of variable size at severa! levels of significance, has been determined for growth, lactation and digestion traits from the equation : n ~ s2 x t2 x 2Jd2 • ...
Development of simplified sampling methods for behavioural data in rabbit does

Alfonso-Carrillo, C.; Martín, E.; Blas, Carlos de; Ibáñez, M.A.; García-Ruiz, A.I.; García-Rebollar, P. (Universitat Politècnica de València, 2017-03-30)

[EN] The aim of this study was to compare the results of different simplified sampling methods for behavioural data compared to reference records of 24-h in order to assess rabbit doe behaviours at different physiological ...
Effect of cage type on the behaviour patterns of rabbit does at different physiological stages

Alfonso-Carrillo, Clara; Martín, Erika; Blas, Carlos de; Ibáñez, Miguel Ángel; García-Rebollar, Paloma; García-Ruiz, Ana Isabel (Editorial Universitat Politècnica de València, 2014-03-28)

[EN] Interest in commercially farmed rabbit welfare has increased in recent years. As a result, new alternativehousing systems have been developed, although they require evaluation in order to demonstrate their potential ...
Effect of early feed restriction on performance and health status in growing rabbits slaughtered at 2 kg live-weight

Romero, Carlos; Cuesta, S.; Astillero, J.R.; Nicodemus, Nuria; Blas, Carlos de (World Rabbit Science. ICTA. UPV, 2010-12-30)

[EN] The effect of a time-limited access to the feeders (8 h per d from 9:30 to 17:30) on fattening performance and health status was studied in rabbits reared until 2 kg live-weight as typical in the Spanish market. For ...
Effects of nutrition on digestion efficiency and gaseous emissions from slurry in growing pigs: II. Effect of protein source in practical diets

Beccaccia, A.; Cerisuelo García, Alba; Calvet Sanz, Salvador; Ferrer Riera, Pablo; Estellés, F.; Blas, Carlos de; Garcia-Rebollar, Paloma (Elsevier Masson, 2015-11)

This research aimed to investigate effects of protein source in practical diets on nutrient excretion and potential emissions of ammonia (NH3) and methane (CH4) in pigs. Three experimental feeds were designed to substitute ...
Effects of nutrition on digestion efficiency and gaseous emissions from slurry in growing pigs: III. Influence of varying the dietary level of calcium soap of palm fatty acids distillate with or without orange pulp supplementation

Antezana Julián, Walter Orestes; Calvet Sanz, Salvador; Beccaccia, Amanda; Ferrer Riera, Pablo; Blas, Carlos de; García-Rebollar, Paloma; Cerisuelo García, Alba (Elsevier Masson, 2015-11)

[EN] The aim of this study was to establish the relationships between faecal fat concentration and gaseous emissions from pig slurry. Five diets were designed to meet essential nutrient requirements: a control and four ...
