“…In recent years, there has been an increase in researchers' interest in establishing reference intervals for different breeds, sexes, and age groups of the Brazilian sheep flock (Batista et al, 2009;Meira Jr et al, 2009;Santana et al, 2009;Madureira et al, 2013;Carlos et al, 2015;Lima et al, 2015;Souza et al, 2016). However, even in these studies, animals in the growth phase are categorized as a generalized age group, without a specific assessment of the changes in metabolic dynamics within the neonatal and growth periods.…”

Ruminants Full-length research article Dynamics of biochemical parameters in lambs during the first four months of life ABSTRACT-We aimed to verify whether age influences the biochemical profile of healthy lambs during the first four months of life by characterizing the dynamics of its parameters and verifying whether there are differences between the profiles of growing animals and the reference values established for adults. Blood samples of 34 ½ White Dorper × ½ Suffolk female lambs were collected at 30, 60, 90, and 120 days of age, and the serum concentrations of total proteins, total globulins, albumin, urea, creatinine, bilirubins (total, conjugated, and unconjugated), total cholesterol, triglycerides, glucose, gamma-glutamyltransferase, aspartate aminotransferase, and creatine kinase were determined. Descriptive statistics of these parameters were performed to compare them with the reference intervals used for adult sheep. Age influenced the dynamics of all the biochemical parameters between 30 and 120 days of age. Moreover, except for the total, conjugated and unconjugated bilirubins, total cholesterol, and aspartate aminotransferase means, the values of the lambs differed from the reference intervals established for adults. In conclusion, there is an influence of age on biochemical parameters in healthy female lambs in the first four months of life, and often the biochemical parameters of young animals differ from those of adults. Therefore, the interpretation of tests performed on growing animals should be made based on specific reference intervals for this age group.

“…As in this study, Cosenza et al (2013) described the mean value of 116.46±1.88mmol/L chloride in healthy, but non-pregnant or lactating ewes. The chloride levels did not mean a pathological process, but could be linked to the mineral salt intake of the ewes during pregnancy (Souza et al 2016), which occurred ad libitum from the salt trough and was added to the feed. Souza et al (2016) described reference values for Dorper ewe electrolytes in Bahia considering gender and age, showing that the lower limit of chloride values of animals aged 12 to 24 months (73,57-142,37mg/dL) was higher than a,b,c,d Means followed by the same lower case letter in the columns did not differ statistically by the Tukey test (P>0.05); A.B Means followed by different upper case letters in the row differed statistically by the t-test (P<0.05); HCO 3 -= 20 to 25mmol/L (Kaneko et al 2008), 19 to 25 mmol/L (Ortolani 2003), Lactate = 1 to 1.33mmol/L (Kaneko et al 2008).…”

“…The gestational period involves several anatomical, hormonal, and metabolic changes due to the preparation for delivery and early lactation. These changes may cause metabolic disorders such as pregnancy toxemia (PT), which affects ewes and goats in the third and final period of pregnancy (Campos et al 2010, Souto et al 2013, Souza et al 2016. Santos et al (2011) studied PT in ewes and found metabolic acidosis explained by ketonemia due to excessive production of ketone bodies (acetoacetate, acetone, and beta-hydroxybutyrate), which is a consequence of lipoxidation.…”

Comparison of electrolyte and acid-base balances of Dorper breed ewes between single and twin pregnancies

et al. 2019

During pregnancy there are modifications in the metabolic profile of sheep that may predispose to the occurrence of metabolic disorders, of which pregnancy toxaemia (PT) is highlighted. Blood gas analysis is detects changes in acid-base and electrolyte balance effectively. The objectives of this study were to study the acid-base and electrolyte balance of sheep during gestation and in the immediate peripartum (up to 48 hours postpartum), comparing single gestation with twins. Sixty healthy sheep of Dorper breed, two to five years old were raised in a semi-intensive system and were divided in two experimental groups: Group 1: 30 ewes, with ultrasonographic diagnosis of single fetus gestation; Group 2: 30 ewes, with ultrasonographic diagnosis of twin pregnancy. The experimental moments were defined as: MI-immediately after artificial insemination (control); MG30 - 30 days of gestation; MG90 - 90 days of gestation; MG120 - 120 days of gestation; MG130 - 130 days of gestation; MG140 - 140 days of gestation; MP - lambing; MPP1 - 24h postpartum; MPP2 - 48h postpartum. At all times 1mL of blood was collected per jugular vein puncture for blood gas evaluation in a portable equipament (I-Stat®). The pH, carbon dioxide pressure (PCO2), bicarbonate (HCO3-), base excess (BE), sodium (Na+), potassium (K+), chloride (Cl-), ionized calcium (Ca+2), lactate, anion gap (AG) were mensured and strong ion difference (SID) were calculed. This work showed that there were changes in acid-base and electrolyte balance in pregnant ewes, due to the decrease in BE, HCO3-, TCO2 and increase of lactate and AG during gestation, but the pH remained normal and did not present any difference among moments in both groups. Comparing the groups, single-gestation ewes presented higher alkaline expenditure at delivery than twin-gestation, evidenced by lower levels of BE and HCO3-. Lower Na+ levels were observed in prepartum; drop in K+ values with advancing gestation; hyperchloremia and hypocalcemia during gestation according to the reference standards for species; decreased iCa+2 levels in the final third of gestation in both groups. It was concluded that the ewes of this study were healthy until the last moment analyzed (48h postpartum), although have shown greater consumption of the alkaline reserve in the peripartum, being more explicit in the single gestation animals. In addition, this situation can be physiological and result in increased energy demand during gestation, more exacerbated by peripartum.

“…The bodies of thoracic vertebrae T5-T6 and T12-T13 were merged. Hematological examination revealed normochromic and normocytic anemia (HT 30.90%) (normal values ranges from 27% to 45%) (BYERS & KRAMER, 2010), while calcium and phosphorus (7.1mg/dL and 5.2 mg/dL, respectively) (normal values ranges from 6.62 to 13.48 for calcium and 3.72 to 12.11 for phosphorus) (SOUZA et al, 2016) concentrations and biochemical parameters were within normal limits for the species. There was no bacterial growth in the synovial fluid.…”

This research described the radiological, clinical and pathological aspects of hypertrophic osteoarthropathy in a seven-year-old Santa Inês ram. The main clinical features were lameness of the thoracic and pelvic limbs, rigid, cracking and enlarged of the humeroradial, humeroulnar and tibiofemoral joints, cervical spine stiffness, and severe lordosis of the thoracolumbar vertebrae. Dyspnea, nasal discharge and abdominal breathing were also observed. On radiographic examination of the thoracic and pelvic limbs, osteoarthrosis with the formation of osteophyte bridging, intra-articular calcification and periosteum reaction were observed. At necropsy were reported bilateral osteophytosis in the humeroradial, humeroulnar, tibiofemoral and interphalangeal joints, and fusion of the bodies of thoracic vertebrae T5-13 T6 and T12-T13. Microscopically, extensive areas of fibrosis were observed in the lungs and the affected joints were thickened by well demarcated and perpendicular orientated woven and trabecular bone proliferation in the epiphysis. The periosteum was also expanded by fibrous connective tissue that extended into and between the new proliferated bone. Based on these findings, hypertrophic osteoarthropathy, which is an unusual condition in sheep, was diagnosed.
