Blood Plasma Metabolic Profile of Aberdeen Angus Bulls during Postnatal Ontogenesis

Abstract

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.

Blood biochemical values in Japanese Black calves in Kagoshima Prefecture, Japan

“…Therefore, increased protein in blood might have reflected efficient and increased protein utilization, and development of immunity with growing. These agree with reports from other investigations [ 8 , 13 , 18 ].…”

“…Therefore, skeletal growth in Japanese Black calves might be higher than Shorthorn calves, and skeletal growth might have decreased with growing. The other researchers also reported the negative relationship between blood ALP and age in calves [ 3 , 18 ].…”

“…Serum biochemical reference values are used to establish normality [ 3 , 13 ] and to diagnose diseases [ 14 ] and development of ruminal function [ 7 , 19 ]. Although many reference values have been established for dairy calves [ 5 , 8 , 13 , 19 ], there have been few published references for beef calves [ 3 , 18 , 22 ]. In particular, the reports for Japanese Black calves have been very scarce.…”

The effect of clinoptilolite as a feed additive on selected rainbow trout ( Oncorhynchus mykiss ) haematological and biochemical parameters, before and after stress treatment

“…In general, glucose as an energy source is constantly required by all body cells and must be therefore maintained at adequate plasma levels (Yousefian et al, 2010). Hyperglycaemia is an expected result of stress (Hoffmayer & Parsons, 2001) and probably the most commonly used indicator of stress responses in fish, its duration depending on the fish's nutrition and water temperature (Pickering et al, 1982). Kanyilmaz and Tekellioğlu, (2016) reported that serum GLUC levels decreased linearly, whilst TAG increased quadratically with increasing dietary zeolite addition in gilthead seabream.…”

Changes in The Liver Transcriptome and Physiological Parameters of Japanese Black Steers During The Fattening Period

“…Blood ALP-mainly released from the liver and bones-is related to liver dysfunction and bone development in beef cattle 21,22 . In growing animals, blood ALP is mainly released from bone tissue; the main tissue that releases the ALP into the blood stream transforms into liver tissue and the overall release decreases with growth 23,24 . In Japanese Black calves, blood ALP concentrations are signi cantly lower in the late growing stage than in the early growing stage, likely due to the slower rate of bone growth with increasing age 23 .…”
