Application of an open circuit indirect calorimetry system for gaseous exchange measurements in small ruminant nutrition

Criscioni Ferreira, Patricia Fabiola (Universitat Politècnica de València, 2016-05-16)

[EN] The main objective of this Thesis was to study the energy metabolism in small ruminants under different nutrition sceneries. As methodology we utilized indirect calorimetry instead of direct calorimetry or feeding ...
Calcium concentration in vitrification medium affects the developmental competence of in vitro matured ovine oocytes

Succu, Sara; Berlinguer, Fiammetta; Leoni, Giovanni G.; Bebbere, Daniela; Satta, Valentina; Marco Jiménez, Francisco; Pasciu, Valeria; Naitana, Salvatore (Elsevier, 2011-03-01)

Composition of free and adherent ruminal bacteria: inaccuracyof the microbial nutrient supply estimates obtained using freebacteria as reference samples and 15N as the marker

González, J; Arroyo, J.M.; Ouarti, M; Guevara-González, J.; Rodríguez, C.A.; Alvir, M.R.; Moya Salvador, Vicente Javier; Piquer Querol, Olga (Cambridge University Press, 2012)

Previous studies have indicated that 15N enrichment of solid-associated bacteria (SAB) may be predicted from the same value in liquid-associated bacteria (LAB). The aims of this study were to confirm this and to measure ...

Raimundo Giménez, Ángeles (Universitat Politècnica de València, 2011-09-06)

SE UTILIZARON 12 OVEJAS (6MANCHEGAS-6GUIRRAS) QUE TRAS PASAR UNA FASE DE ADAPTACIÓN ( 13 DIAS) Y OTRA EXPERIMENTAL (13 DIAS) EN LA QUE SE REALIZARON MEDIDAS DE DIGESTIBILIDAD, BALANCES ENERGÍA Y RESPIROMETRÍA NO SE ...
Effect of subclinical mastitis on proteolysis in ovine milk

Marti-De Olives A.; Le Roux, Yves; Rubert-Alemán J.; Peris Ribera, Cristófol Josep; Molina Pons, Mª Pilar (American Dairy Science Association, 2011)

The aim of this work was to evaluate the effect of intramammary infection (IMI) on the endogenous proteolysis of milk. Four control checks were carried out in the half-udder milk of 10 ewes that acquired unilateral subclinical ...
Effects of the comminution rate and microbial contamination of particles in the rumen on in situ estimates of protein and amino acid digestion of expeller palm kernel and rapeseed meal

Gonzalez, J.; Arroyo, J.M.; Mouhbi, R.; Guevara-Gonzalez, J.; Moya, V.J.; Piquer Querol, Olga (Wiley, 2014-05)

BACKGROUND Microbial corrected effective in situ estimates of ruminal undegraded fraction (RU) and intestinal effective digestibility (IED) of dry matter (DM), crude protein (CP) and amino acids (AA) of expeller palm kernel ...
Estudio preliminar para determinar las necesidades de mantenimiento en ovejas de raza Manchega y Guirra

Fernández Martínez, Carlos Javier; López Luján, Mª del Carmen (2011)

[EN] Twelve sheep of two races were used, six of each race, Manchega and Guirra; two and a half years old, not pregnant, dried and fed under maintenance. Sheep were weighted at the beginning and end of the trial consisting ...
