“…Our results are inconsistent with those of Balikci et al (2007) who reported a gradual increase (p < 0.05) of cholesterol levels during pregnancy compared with values obtained at 45 th days postpartum. Hamadeh et al (1996) and Al-Dewachi (1999) pointed a high cholesterol levels in pregnant ewes compared to empty ones.…”

“…Furthermore, Krajnicakova et al (1993), Hamadeh et al (1996), and Nazifi et al (2002) have reported high levels of triglycerides during late gestation; a similar result is underscored by Balikci et al (2007) who noted a significant increase (p < 0.05) of triglyceride levels during pregnancy compared to 45 th days post partum, On 100 and 150 th days of gestation, these rates were higher among ewes who had two lambs, on the other hand, Tanaka et al (2007) found no significant difference of serum triglycerides during lactation or dry period. West (1995) recorded higher uraemia in pregnant ewes than in lactating or empty ones; other authors have found no effect of pregnancy on uremia (Scott and Robinson, 1976;Brozostowski et al, 1996;Meziane 2001).…”

“…The identification of metabolism change of such sheep in various reproduction phases, the determination of metabolic blood profiles, including serum mineral and biochemical parameters is necessary to study ruminant metabolism disorders and can provide useful information on the animal nutritional status (Balikci et al, 2007). Correspondingly, mineral content and biochemical *Corresponding author.…”

Investigations were conducted to determine the influence of physiological stage and parity on some indicators of energy, nitrogen and mineral metabolisms in sheep Ouled Djellal living in the Algerian Southeast arid area. The study was carried out on 100 clinically healthy multiparous and primiparous ewes, aged 2 to 7 years. The animals were divided into three ewe groups: Pregnant (P), lactating (L), and empty (E). Biochemical analysis of blood samples concerned the determination of the values of 11 metabolites [glucose, cholesterol, triglycerides, urea, total protein, albumin, calcium (Ca), phosphates (PO 4 ), sodium (Na), potassium (K), and magnesium (Mg)]. The results showed that pregnant ewes and multiparous ones have the lowest blood glucose levels and the highest proteinemia. However, the lowest total protein and albumin values were found in empty sheep. Cholesterol and triglyceride levels were the highest in lactating and primiparous ewes. In this study, the most important calcium levels were recorded in lactating ewes which showed the lowest magnesium levels. The pregnant ewes had the highest sodium levels and low phosphatemia. Potassium levels were comparable in all animals. Statistical analysis showed that the physiological stage has a significant influence (p < 0.05) on serum glucose, triglycerides, phosphorus and potassium levels and a highly significant effect (p < 0.001) on urea, and magnesium levels. No parity effect has been observed in our study.

The aim of the study was to evaluate the megakaryocyte lineage of bone marrow and coagulation parameters in fallow deer during the last month of pregnancy. The animals were managed in the barn-feeding system. Twenty female fallow deer, aged 2-3 years, divided into 2 groups were used in the study. Group 1 comprised the females in the last month of pregnancy, and the non-pregnant females were used as the control. All the animals were clinically healthy. Coagulation parameters were measured in all the deer: thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT), and plasma concentrations of fibrinogen, D-dimer, and antithrombin III. A quantitative assessment of bone marrow was carried out for the erythroblastic, myeloid, lymphoid, monocyte-macrophage, and megakaryopoietic cell lines. A detailed analysis of megakaryocyte lineage was performed after whole blood and platelet count.There were no significant differences in the erythroblast, granulocyte, monocyte-macrophage and lymphoid systems between the animal groups. Thrombocyte count in the pregnant deer was lower than that found in the control group. Bone marrow smears revealed a slightly decreased megakaryocyte count, while the megakaryoblast and promegakaryocyte counts were unchanged. The analysis of coagulation parameters showed increased levels of fibrinogen, thrombin time, prothrombin time and activated partial thromboplastin time in the pregnant animals. The study suggested a hyperactivation of the coagulation system with a slight reduction in the megakaryocyte count in bone marrow, and a reduction in platelet count in peripheral blood at the end of pregnancy.

“…Sendo assim, pode-se verificar que estes aditivos modificaram a produção de ácidos graxos voláteis no rúmen, entretanto, mantendose dentro da faixa fisiológica. Uma vez que estes ácidos graxos, são utilizados como substratos para a síntese de triacilgliceróis e glucose (RIBEIRO et al, 2004, BALıKCı;YıLDıZ;GÜRDOĞAN, 2007). Além disso, a média de atividade da enzima CK foi menor (P<0,01) no grupo GM2, indicando menor utilização desse tecido como fonte de proteína, uma vez que este tecido é importante reserva de aminoácidos para o organismo (SOBIECH; KULETA, 2002).…”
