“…FRIEDRICHS et al (2012) concluded that adoption of these guidelines by the entire veterinary community would provide easier communication and information dissemination. It is particularly important for herd health monitoring, as rearing and feeding conditions often cause variations in the concentrations of many serum/plasma metabolites, and their "exit" from the reference range in the published literature (BRAUN et al, 2010;KJELGAARD -HANSEN and LUNDORFF JENSEN, 2010).…”

Haematological and blood biochemical variables are key elements for routine assessment of animal health status, with implications in animal production and food safety. However, only reliable reference intervals of haematological and biochemical blood variables can provide the basis for accurate interpretation of the obtained blood results. Haematological and biochemical blood values critically dependent on living conditions, region, husbandry, rearing location, and diet. The aim of this study was to determine the reference intervals for selected important and informative haematological and blood biochemical variables for females of the Croatian indigenous sheep breed, Lika pramenka. We used several advanced statistical methods and assessed their applicability for determination of relevant reference intervals under conditions specific to indigenous sheep breeding. The results show that the reference intervals from the available literature are orientational but not adequate for the specific challenges encountered in raising indigenous breeds in their natural habitat. This was illustrated by the large number of clinically healthy animals with blood variable values falling outside the reference intervals given in the sources available previously.

“…The main ketone body found in blood of pregnant sheep is β-hydroxyburate; its concentration can be used to detect animals at risk to develop HELMINTHOLOGIA, 50, 3: 161 -166, 2013 Potential association between trematode infections and development of pregnancy toxaemia in sheep -1 should be considered to distinguish animals at risk to develop the disorder. Otherwise, if the number of foetuses carried had been determined, then β-hydroxybutyrate concentration should be measured only in the blood of animals carrying multiple foetuses; in this case, the cut-off value to be used for identifying animals at risk is 1.1 mmoL L -1 (Sargison 1995(Sargison , 2007Braun et al, 2010;Brozos et al, 2011). Objective of the work was to study a potential association between trematode infections in pregnant ewes and concentrations β-hydroxybutyrate.…”

Potential association between trematode infections and development of pregnancy toxaemia in sheep

et al. 2013

Objective of the work was to study a potential association between trematode infections in pregnant ewes and concentrations β-hydroxybutyrate, which is a ketone body found in animals with pregnancy toxaemia. After administration of a long-acting nematocide, 80 pregnant sheep, infected with trematodes, were allocated as follows; primigravidae ewes in group P-A remained untreated and in group P-B were given netobimin; multigravidae ewes in group M-A remained untreated, in group M-B were given netobimin and in group M-C were given rafoxanide. We collected faecal samples for trematode epg counting and blood samples for measurement of β-hydroxybutyrate concentrations. Mean faecal epg counts of D. dendriticum and F. hepatica decreased significantly after netobimin administration; mean faecal epg counts of F. hepatica, but not of D. dendriticum, decreased significantly after rafoxanide administration. Between P-A and P-B, the difference in mean blood β-hydroxybutyrate concentrations was significant (P = 0.036) immediately after lambing. Between M-A or M-C and M-B, it was significant (P ≤ 0.002) 28 days after trematocide administration and immediately after lambing; between M-A and M-C, no significant difference was evident. Immediately after lambing, mean blood β-hydroxybutyrate concentration in primiparous/multiparous ewes with Dicrocoelium faecal output ≤150 epg was 0.21/0.64 mmol L -1 , respectively, and in primiparous/multiparous ewes with Dicrocoelium faecal output >150 epg was 0.40/0.93 mmol L -1 , respectively (P = 0.704/<0.001, respectively). Mean blood β-hydroxybutyrate concentration in group P-C/M-C ewes with Fasciola faecal output of <16/<30 epg was 0.47/0.68 mmol L -1 , respectively; that in group P-C/M-C ewes with Fasciola faecal output of ≥16/≥30 epg was 0.56/0.85 mmol L -1 , respectively (P = 0.620/0.278, respectively). The results indicate that more trematode-infected adult ewes were found to have increased β-hydroxybutyrate blood concentrations and point out to a potential role of liver trematode .... infections in predisposing adult ewes to pregnancy toxaemia.

“…In fact, the hypothalamic pacemaker, directly innervated from retina, results as the principal factor involved in determining circadian rhythms (Moore Ede et al 1986). In normal conditions, albumin variations are affected by numerous factors such as heat haemoconcentration that can take to an increase of its value (Braun et al 2010). In this case, the opposite trend shown for the two small ruminant species is attributable only to a difference, found by other authors, in melatonin pattern.…”

“…Growing interest is rising about the serum proteins, which concentration reflects the physiological conditions of an animal and results as an important diagnostic tool to assess animal health (Castillo et al 1997, Castillo et al 1999, Antunovic et al 2004, Alberghina et al 2010. Different studies investigated the more frequent pathologies and their relationship with the serum protein variations (Yarim et al 2009, Braun et al 2010. In ruminants, the serum protein contents, which differ between sheep and goat, were assessed as necessary to study metabolic disorders (Alberghina et al 2010, Waziri et al 2010.…”

The aim of this study was to assess the seasonal trend of the serum protein content of sheep and goats. The tested animals were six female goats (Maltese breed) and six female sheep (Valle del Belice breed). All animals were clinically healthy and not pregnant or lactating before or during the study. On blood samples, collected through an external jugular venipuncture every 30 days for 12 months, electrophoresis was performed using a semiautomated AGE system and then electrophoretic curves with the relative protein concentrations were analyzed. One way for repeated measure analysis of variance (ANOVA) was applied to determine the effect of time and by means of cosinor rythmometry, mesor (mean level), amplitude (half the range of oscillation) and acrophase (Φ, time of peak) were determined. The results showed a seasonal rhythm on Albumin and Alumin/Globulin ratio for sheep and goats, with different acrophases, winter for goats and spring for sheep. A seasonal rhythm was shown also in Alpha 2 globulins by sheep and in Beta globulins by goats. The difference in the acrophase can be attributed to a different production pattern of melatonin in goat, so the liver production of albumin is major during the winter that has a longer scotophase.
