“…anaemia presented a significant reduction in serum IGF-I compared to calves with optimal iron concentration on day 10. The results obtained in our study are similar to other studies that investigated metabolic and endocrine changes during iron deficiency in veal calves (Ceppi and Blum 1994;Blum and Hammon 1999;Podhorský et al 2007). The IGF-I status markedly depends on energy and protein intake, as also shown in calves (Hammon and Blum 1998;Blum and Baumrucker 2002).…”

“…Although the positive correlation provides no indication of cause and effect, we consider that sufficient iron is required for normal secretion of IGF-I. Indeed, in situations of iron deficiency in rats, iron is a critical determinant of IGF-I regulation (Tran et al 2012), and previous research has also shown that iron deficiency reduces GH-mediated IGF-I secretion (Ceppi and Blum 1994). Nevertheless, conversely to what was observed in the iron deficiency state, parenteral administration of iron in calves during the early postnatal period resulted in a rise of serum IGF-I concentrations (Moosavian et al 2010).…”

Relationship between serum iron and insulin-like growth factor-I concentrations in 10-day-old calves

Newborn calves are often deficient in iron and progressive reduction in blood iron concentration occurs over the first weeks of life. Some reports indicate the importance of interactions among iron and components of the insulin-like growth factor system. The aim of the study was to determine if there is a relationship between serum iron and insulin-like growth factor-I concentrations in neonatal calves. Blood samples were collected from 16 female Holstein-Friesian calves on day 10 of age. Erythrogram determination and measurements of serum iron, total protein, albumin, total iron binding capacity and serum insulin-like growth factor-I concentrations were performed. Haematological values were measured using an automatic analyzer, biochemical properties were determined spectrophotometrically, insulin-like growth factor-I concentration was measured by radioimmunoassay. Calves were divided into 2 groups according to iron concentrations; the first group of iron-deficient calves (n = 8, Fe < 10 μmol/l) and the second group of calves with optimal iron concentration (n = 8, Fe > 18 μmol/l). Blood indicators in all calves from the first group followed a pattern typically observed in anaemic calves. Insulin-like growth factor-I concentrations were significantly (P < 0.01) lower in the first group compared to the second group. However, insulin-like growth factor-I very strongly correlated with iron in calves from the second group compared to iron-deficient calves (r = 0.624; P < 0.01 and r = 0.478; P > 0.05, respectively). Based on our results, iron seems to have an important relationship to secretion of insulin-like growth factor-I in 10-day-old calves. This is the first report about such relationship in this age group of animals. Calf, haematology, IGF-I, iron deficiency

“…In all the sampling periods, the serum Fe was lower than the reference value of 10-29 μmol/L for adult cattle reported by Radostis et al (2000). According to the literature, calves with Fe deficiency present reduced insulin concentrations (Ceppi and Blum 1994). Glucose levels in this study were slightly higher than the reference values reported for adults (1.9-3.8 mmol/L; Radostis et al 2000) even if no statistical differences were detected among sampling periods.…”

An evaluation of blood chemistry profile in relation to specific stages of livestock cycle can help better understand variations in physiological conditions in order to adjust management systems to animal needs. In addition to basal hematological investigation, the acid-base balance and blood gases are essential tools in evaluating metabolism in calves. The relationship between blood gas parameters, diet and growth should be further investigated.The aim of this study was to evaluate changes in acid-base status, blood gases, serum chemistry and hematological parameters in veal calves at different periods of livestock cycle.One hundred twenty-eight healthy cross breeding calves were enrolled in a farm in North-East Italy. Blood samplings were carried out from the jugular vein on day 1 (t1), 60 (t2) and 150 (t3) after arrival. Blood gas analysis was performed and hematological parameters were evaluated. One-way ANOVA and Tukey-Kramer post-hoc test were performed to assess differences between blood parameter values at the different periods.The main differences in blood gas parameter levels during the livestock cycle concerned pH, Base Excess and HCO 3 with higher values recorded in t3. Urea, creatinine, gamma-glutamyl transpeptidase and bilirubin mean values were significantly higher in t1 than in t2 and t3. Aspartate aminotransferase increased from t1 to t2 and t3. Alkaline Phosphatase was higher in t2. Fe levels severely dropped in t2 and in t3, and the decrease led to a restrained but significant reduction in haemoglobin values. A correspondent decrease in the other haemocytometric parameters was found.

“…There was a marked growth response to the administration of iron even in calves that were fed hay and grain in addition to milk [15,16]. It seems that sufficient iron is needed for normal appetite, secretion of IGF-I and tri-iodothyronine, and glucose utilization [20,27,28].…”

The present study was designed to evaluate the effects of parenteral iron on red blood cell parameters, performance, and health in dairy Holstein calves. Twenty neonatal calves were equally divided at random into two groups, one of which served as controls. Care was taken to ensure homogeneity of sex, age, and general health status of the animals. The controls received a normal diet and water ad libitum, while the study animals were injected with 1 g iron as Fe-dextran 2 days after birth. A daily record was kept of the calves' weight and growth parameters. At periods of 24-48 h after birth and at 14, 28, and 42 days of age, jugular blood was drawn from all the experimental and control animals to measure the packed cell volume, red blood count, hemoglobin, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and iron levels. At the start of the experiments, there were no significant differences between these parameters between the two study groups (p > 0.05). With time, significant differences were seen between most of the values measured (p < 0.05) except for the mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and iron level. Significant differences were seen for total weight gain and mean daily weight gain, which were higher in the iron-supplemented group (p < 0.05).
