The effect of age at the first mating and herd size on the lifetime productivity of sows
(Institut national de la recherche agronomique (França)EDP Sciences, 2003)The effect of age at the first mating and herd size were evaluated in the reference Spanish Databank (BDporc) of 37 698 sows born between 1991 and 1995 and with individual lifetime records. The data included dates of births ... -
Urinary excretion of purine derivatives as an index of microbial protein synthesis in the camel (Camelus dromedarius)
(Cambridge University Press, 2004)Five experiments were carried out to extend knowledge of purine metabolism in the camel (Camelus dromedarius) and to establish a model to enable microbial protein outflow from the forestomachs to be estimated from the ... -
A cryopreservation procedure for the rumen protozoon Entodinium caudatum: estimation of its viability by fluorescence microscopy
(Blackwell Science, 2004)Aims: To study the viability of a culture of the rumen protozoon Entodinium caudatum after a cryopreservation procedure by a fluorescence microscopy staining method. Methods and Results: Fluorescence method is based on ... -
Urinary excretion of purine derivatives in Bos indicus 3 Bos taurus crossbred cattle
(Cambridge University Press, 2005)Four experiments were performed to study the kinetics of purine metabolism and urinary excretion in Zebu crossbred cattle. Fasting excretion was established in Expt 1, using eighteen male Bos indicus £ Bos taurus crossbred ... -
Protein recycling in growing rabbits: contribution of microbial lysine to amino acid metabolism
(Cambridge University Press, 2005)To study the absorption of microbial lysine in growing rabbits, a labelled diet (supplemented with 15NH4Cl) was administered to six animals (group ISOT); a control group (CTRL, four rabbits) received a similar, but ... -
Comparison of fatty acid profiles of edible meat, adipose tissues and muscles between cocks and capons
(Institut national de la recherche agronomique (França)EDP Sciences, 2005)The effect of caponisation on fat composition by parts (wing, breast, thigh, and drumstick) and tissues (skin, subcutaneous adipose tissue, intermuscular adipose tissue and muscle) was examined in the present study and ... -
Interrupció del creixement en la hibernació del gripau corredor (Epidelea calamita) en zones semiàrides
(Institució Catalana d'Història Natural, 2005)Les particularitats de les poblacions amfíbiques que viuen en zones semiàrides sotmeses a un alt estrès ambiental es posen de manifest mitjançant estudis d’esqueletocronologia. L’estudi pretén avaluar la correlació histològica ... -
Relationship between rainfall and Neospora caninum-associated abortion in two dairy herds in a dry environment
(Wiley, 2005)The possible direct relationship between climate variations and abortion in Neospora caninum-infected cows has not been studied. The objective of this study was to determine whether climate changes could be a risk factor ... -
Estimation of the additive and dominance variances in South African Landrace pigs
(South African Society for Animal Science, 2006)The objective of this study was to estimate dominance variance for number born alive (NBA), 21- day litter weight (LWT21) and interval between parities (FI) in South African Landrace pigs. A total of 26223 NBA, 21335 LWT21 ... -
Genetic parameters for canalisation analysis of litter size and litter weight traits at birth in mice
(BioMed Central, 2006)The aim of this research was to explore the genetic parameters associated with environmental variability for litter size (LS), litter weight (LW) and mean individual birth weight (IW) in mice before canalisation. The ... -
Preliminary study on the effect of exposure to low temperature on the viability of both mixed and monocultures of rumen protozoa
(Institute of Environmental Sciences, Jagiellonian University, 2006)The effect of low temperatures on the viability of rumen protozoa was studied. In Trial 1, samples of mixed rumen contents were diluted and cultured at 38, 15 and 5°C for 2, 4 and 6 h, respectively. Viability of Isotrichidae ... -
Kinetics of the appearance of cereal alkylresorcinols in pig plasma
(Cambridge University Press, 2006)Alkylresorcinols (AR) are phenolic lipids found in high amounts in wholegrain wheat and rye. They may be important as bioactive components and/or biomarkers of wholegrain wheat and rye intake. AR absorption was studied ... -
Effect of growth selection on morphology in Pirenaica cattle
(Institut national de la recherche agronomique (França)EDP Sciences, 2006)Twelve variables were identified to define morphology in 109 calves sired by eight Pirenaica bulls widely used in artificial insemination. The effect of selection for weight at 210 days of age (W210) was detected from the ... -
