“…T ransition period in ewes, 4 weeks around the time of lambing, is physiologically stressful and is considered as a crucial stage in the production cycle of sheep (Pastrana et al, 1991). During that period, significant metabolic and immunological challenges occur to meet the requirements of the animal, as approximately 75 -80% of the fetal growth occurs in the last 4-6 weeks of pregnancy, with consequent significant productive and reproductive disorders (Sormunen-Cristian and Jauhiainen, 2001;Overton and Waldron, 2004;Balıkcı et al, 2007).…”

“…The stress of parturition, the onset of lactation, and the high turnover of fluids, salts and soluble organic materials, are the main stressful conditions for ewes at the transition period (Sormunen-Cristian and Jauhiainen, 2001;Guo et al 2007;Constable et al, 2017). Thus, minerals' metabolism particularly calcium and phosphorus, undergoes substantial changes to maintain colostrum and milk synthesis (Yokus et al, 2004).…”

This technical research article investigated the changes in the hemato-biochemical profile in Barki ewes during the transition period. A total of 15 healthy pregnant Barki ewes (age, 4.9 ± 0.7 years old; weight, 38.5 ± 4.9 Kg) were randomly selected for the current study. Blood samples were collected from the selected ewes via jugular vein puncture during the transition period at five different time points; 4 and 2 weeks prior the estimated date of delivery (EDD), at the parturition time, then at 2 and 4 weeks post-partum. Red blood cells (RBCs) count and packed cell volume (PCV) were significantly (P<0.05) decreased 2 weeks before the EDD and at the parturition time. Mean corpuscular volume (MCV) was significantly (P<0.05) decreased 4 weeks post-partum. The neutrophil count and neutrophil/lymphocyte ratio were significantly (P < 0.05) increased 2 weeks post-partum. The level of β-hydroxy butyric acid (BHBA) and concentration of non-esterified fatty acid (NEFA) in the serum were significantly (P<0.05) increased 2 weeks before EDD, at the parturition time, and 2 weeks post-partum. Both cholesterol and triglyceride levels increased significantly (P<0.05) 2 weeks before EDD and at the parturition time. Leptin level was significantly (P<0.05) decreased at 2 weeks and 4 weeks post-partum. Glucose level increased significantly (P<0.05) at the parturition time then decreased significantly (P<0.05) at 2 weeks post-partum, after which it increased again 4 weeks post-partum. Total protein level was significantly (P<0.05) increased 2 weeks post-partum. The level of both calcium and inorganic phosphorus was significantly (P<0.05) decreased at the parturition time and 2 weeks post-partum. The results revealed that Barki ewes showed profound physiological alterations during the transition period which are not necessarily indicative of a disease, but reflect physiological variations. Therefore, metabolic profile test was needed to determine the nutritional status of Barki ewes, and to take the possible preventive measures that increase ewes’ productivity and predict health disorders.

“…Higher (P<0.05) lipid peroxidation values were observed during the 90 th day of pregnancy followed by 15 d before expected day of lambing and lower values were recorded on 15 th day of pregnancy. This could be explained by the fact that, 80% of foetus growth occurs in the last 2 months of pregnancy, so ewes exhibit a dramatic increase in metabolism during this period [ 27 ]. The rapid growth of foetus during the last 6 weeks of pregnancy causes an increase in fatty acid consumption from the mother’s fat reserve and production of hydrogen peroxide that has been enhanced by intense lipolisys and mobilization of fatty acids from the body deposits during pregnancy [ 28 , 29 ].…”

Guar meal (GM) can be considered as an alternative protein source for the livestock and has a potential value as a feed to animals with a high protein content ranging between 45–55%. A study was conducted to evaluate the effect of partial replacement of groundnut cake (GNC) with guar meal (GM) on reproductive efficiency, hormone profile, antioxidant status in Deccani ewes fed sorghum stover based complete feed blocks (SSCFB). Twenty-one non-pregnant Deccani ewes (b. wt. 23.34 ±0.40 kg; 2–4 years old and body condition score 2.51±0.56) were randomly divided into three groups to contain 7 animals each in a completely randomized design. Three dietary treatments viz. S1: conventional feeding (sorghum stover and concentrate mixture fed separately in 50:50 ratios to meet the requirement), S2: SSCFB with GNC as protein supplement in concentrate mixture and S3: SSCFB with GM replacing GNC nitrogen of S2 at 50% level. The ewes were synchronised for estrus with progesterone impregnated intravaginal sponges and naturally mated. The ewes were fed at the rate of 3.1 and 3.7% of their body weight from 1st day of experiment—to 108th day of gestation and from 108th day of gestation to till lambing, respectively. The replacement of 50% of GNC nitrogen with GM and densification of diet had no effect (P>0.05) on average DMI (g), antioxidant status, progesterone concentration, conception rate, non return rate, no of matings per service, lambing rate, body weights of lambs at birth, 15 and 30 days of age. GNC can be partially replaced by GM in the ewes diet without any adverse effect on reproductive parameters, antioxidant status, progesterone concentration and weight of lambs.

“…The energy requirements of pregnant ewes increase significantly towards the end of gestation, during which 70 to 80% of foetal growth occurs (Sormunen-Cristian and Jauhiainen, 2001). Similarly, during the first 2 weeks of lactation, the export of nitrogen and energy in milk is very high and the animals can not ensure it without the mobilization of their reserves (Tissier and Thériez, 1978).…”

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.
