Blood Plasma Metabolic Profile of Aberdeen Angus Bulls during Postnatal Ontogenesis

et al. 2010

Selected indicators for the metabolic profile of blood plasma in 22 Aberdeen Angus bulls reared by the extensive method were monitored during postnatal development (from 4 to 564 days of age), including total proteins, albumin, urea, creatinine, glucose, cholesterol, triacylglycerols, bilirubin, alkaline phosphatase, alanine transaminase, aspartate transaminase, tyroxin, triiodothyronine, calcium, inorganic phosphorus, magnesium, potassium, sodium, chlorides, copper, zinc and iron. In assessing the relationship of age to the indicators of the internal environment, values of correlation coefficients for total proteins (r = -0.70; p < 0.01), albumin (r = -0.56; p < 0.01), urea (r = -0.73; p < 0.01), glucose (r = -0.38; p < 0.01) and triiodothyronine (r = -0.82; p < 0.01) were established. Significant relationships were shown between the temperature of the external environment and the amount of total proteins (r = -0.38; p < 0.01), urea concentration (r = -0.41; p < 0.01), ALP (r = 0.58; p < 0.01) and ALT (r = 0.45; p < 0.01) activity. Temperature also showed a significant impact on the concentration of P (r = 0.57; p < 0.01), K (r = -0.69; p < 0.01) and Zn (r = 0.33; p < 0.01). The work yields important information on changes in the indicators of the metabolic profile of the blood plasma of bulls during postnatal development under defined nutritional and temperature conditions that can be used as reference values for evaluating health status as well as nutrition level.

“…However, serum urea-N levels were lower (P , 0.001) and creatinine tended to be lower (P , 0.10) in the group FR than in the group C. In addition, creatinine increased with time (P , 0.001). In young growing ruminants, these two metabolites are deemed to be important indicators of the protein nutritional state (Cabaraux et al, 2005). In particular, the amount of creatinine released in the blood is related to the growth rate of the muscular tissue, as the precursor creatinine is mainly contained in the skeletal muscles (Doornenbal et al, 1988).…”

the effect of rearing system (confined (C) v. free ranging (FR)) and season (spring v. summer) was evaluated on behaviour, immune and blood parameters and beef production (experiment 1). From February to August 2008, the effect of rearing system was only evaluated on beef production (experiment 2). A total of 12 Podolian young bulls were used each year. They were slaughtered at 18 and 15 months of age in 2007 and 2008, respectively. Herbage mass and pasture composition were monitored during the 2 years. Pasture availability, in terms of herbage mass and composition, as well as its seasonal development, was similar in the 2 years. In the first experiment, FR animals spent more time walking ( P , 0.05), feeding ( P , 0.001) and standing ( P , 0.01) and showed a lower number of agonistic ( P , 0.05) and non-agonistic social interaction than C animals ( P , 0.01). Significant lower concentrations of serum urea nitrogen ( P , 0.001) and creatinine ( P , 0.10) in FR animals indicated a lower protein nutritional status due to inadequate protein availability at pasture. As a consequence, average daily gains ( P , 0.05), slaughter weight ( P , 0.05) and body condition score ( P , 0.01) were lower in grazing animals as compared with C bulls. Cellular immune responsiveness was higher in FR animals ( P , 0.05). Similarly, antibody titre to keyhole limpet hemocyanin was higher in FR bulls at the 2nd and 3rd month after antigen injection ( P , 0.05), whereas it tended to be higher at the 4th month ( P , 0.10). In both experiments, grazing negatively affected meat colour in terms of lightness. Eighteenmonth-old bulls also showed lower final weight, weight gain and body conditions when kept outdoor: a possible consequence of nutrient deficits, as suggested by the metabolic status of FR animals. The same animals, however, benefited from FR in terms of natural behaviour expression and immune responsiveness. When the experiment was replicated the subsequent year, on animals slaughtered at 15 months of age, no differences between the performances of FR and C animals were detected. The earlier slaughter age system was also proportionally less dependent on external inputs as grazing was not extended to the dry season when herbage mass availability was lower.

“…Em estudo de vacas em terminação Cabaraux et al (2005) não encontraram relações significativas nas concentrações de glicose plasmática, N-amino e uréia. O mesmo ocorreu com as concentrações de T3, T4 e IGF-I quando comparadas durante o período de acabamento.…”

“…Os autores consideraram que estes níveis mais baixos de IGF-I circulante, quando comparados aos valores de novilhas Angus e Hereford, podem ser resultado de migração do hormônio para os tecidos periféricos por causa do maior desenvolvimento muscular em raça de dupla musculatura.Os valores encontrados porEllenberger et al (1989) para novilhos com 430 kg de peso vivo não diferiram entre si e foram maiores, 214,9 ng/mL para animais controle e 227,3 ng/mL para o grupo compensando, que os valores observados porCabaraux et al (2005), mas ainda inferiores aos observados no presente trabalho.No entanto,Ellenberger et al (1989) observaram queda nas concentrações ao longo do tempo, sendo que aos 510 kg de peso vivo os valores dos animais que sofreram restrição foram superiores aos do grupo controle.No estudode Hayden et al (1993), houve aumento linear nas concentrações de IGF-I, tendo o grupo restrito valores inferiores ao grupo sem restrição. Aos 60 dias de realimentação os valores estavam próximos a 350 ng/mL.…”
