“…Since oxygen diffusion from the maternal to foetal blood depends largely on the difference in oxygen tension between the two compartments (Guyton and Hall 1996), the higher MCH could assist in maintaining or even increasing the oxygen carrying capacity of the dam and consequently, enhancing oxygen supply to the foetus. However, in contrast to the finding of this study, Fonteque et al (2010) and Mohammed et al (2014) reported that physiological status does not affect MCH and MCHC values Saanen goats and ewes, respectively.…”

ABSTRACT:The current study was aimed at evaluating the effect of heat stress (during the hot-dry period) on some physiological variables, haematology and erythrocyte osmotic fragility (EOF) in bucks, pregnant (single and twin) and lactating Red Sokoto (RS) goats. Forty apparently healthy adult goats were used for the study and were allotted to four groups [bucks (n = 10), pregnant (n = 10) dry (n = 10), and lactating (n = 10) does]. The pregnant goats were further re-grouped according to number of foetuses (single foetus, n = 5 and twins, n = 5). The temperature-humidity index and physiological variables measured were significantly higher in the afternoon compared to morning hours. Pregnant does had higher respiratory and pulse rates than the dry does, but no significant change (P > 0.05) in rectal temperature was observed between groups. On the basis of sex, bucks had lower (P < 0.05) mean corpuscular volume (MCV) than other groups, in addition to having higher (P < 0.01) mean corpuscular haemoglobin (MCH) and total leucocyte counts than dry does. Pregnant does exhibited significantly lower (P < 0.05) packed cell volume, but significantly higher (P < 0.05) MCH and mean corpuscular haemoglobin concentrations (MCHC) than lactating does. Does with a single foetus had significantly lower (P < 0.05) MCV, but higher MCHC than does with twin pregnancies. Using EOF as a biomarker of oxidative stress, erythrocytes of bucks were significantly more resistant to hypotonic haemolysis than those of dry, pregnant and lactating does, with no significant difference in EOF between does of different groups. The erythrocytes of single and twin pregnancies showed similar haemolysis pattern. In conclusion, sex, lactation, and the number of foetuses carried by pregnant does significantly influences physiological and haematological variables in RS goats during the hot-dry season. Also, during heat stress, the changes in physiological variables seem to enhance favourable adaptation by preventing an increase in rectal temperature even in twin pregnancies.

“…We observed a higher PCV in lactating compared to pregnant does. Lower prepartum, but higher postpartum PCV has been reported in goats (Azab and Abdel-Maksoud 1999) and ewes (Obidike et al 2009;Mohammed et al 2014). In goats, blood volume expands in parallel with increases in body weight during pregnancy (Olsson et al 2001).…”

On the other hand, in another study, the authors reported elevated postpartum Hb and Hct values as compared to the prepartum period [15] . In this study, postpartum RBC indices (RBC, Hct, Hb, and MCV) were found to be lower than levels in 1 wk (±2 days) before expected parturition.…”

Erythrocyte indices, total iron binding capacity (TIBC) and unsaturated iron binding capacity (UIBC) values provide important information for the diagnosis of anaemia in iron deficiency conditions and inflammatory diseases. The aim of this study was to evaluate the serum iron status and its relation with haematological indexes before and after parturition in sheep. Blood samples were collected from pregnant (n=30) and non-pregnant aged-matching Ivesi sheep (n=30), housed under the same conditions, at 1 week (wk) (±2 days) before expected parturition, in parturition (baseline), at day 1 and at 1, 2, 3, 4, 6, 8 and 12 th wk subsequent to the parturition, to determine the serum levels of iron (SI), TIBC and UIBC as well as the haematological parameters. Erythrocyte (RBC) count, haematocrit (Hct) and haemoglobin (Hb) values dropped at 12 wk (P<0.05) according to 1 wk (±2 days) before expected parturition and during parturition. Mean corpuscular volume concentrations were also found lower (P<0.05) at 4-12 wk after parturition, in comparison with their baselines. After the parturition, SI concentration decreased at day 1 (P<0.05) and then remained low (P<0.05) during the study. TIBC was higher for the first 2 wk, but was lower at 6-12 wk compared with its baseline (P<0.05). UIBC values were in parallel to TIBC values after the parturition. In conclusion; negative effects on leukocytes of metabolic stress after delivery should be taken into consideration, as it can trigger the potential problems during this period. In postpartum period, SI levels along with erythrocyte indices can be useful parameters to follow the iron loss by fetus and colostrum. Incompatible results of TIBC and UIBC levels with SI and erythrocyte indices in this study showed that TIBC and UIBC may not be useful biomarkers to evaluate serum iron values, particularly in postpartum period.

“…In this study haemoglobin and PCV values were not significantly different between late pregnant and early lactating goats. In another study, it was found that blood values in sequentially monitored sheep and goats generally reflected a rise in these values in late gestation and parturition, declining in the periparturient period, and declining further in early lactation (El Sherif and Assad, 2001;Iriadam, 2007;Mohammed et al, 2014;Sharma et al, 2015;Manat et al, 2016). Animals in sequential studies are usually managed under experimental conditions such as similar diets and adequate anthelmintic control which were not controlled in this study.…”

“…Regarding age and physiological stage, higher Hb and PCV values are reported for 6-12 month old lambs (Mohammed et al, 2014) and kids (Mbassa and Poulsen, 1992) compared with pregnant and lactating animals. Pregnant goats from hot climates however, can exhibit higher PCV values than lactating animals, attributed to haemoconcentration (Habibu et al, 2014).…”

A study was conducted to determine hematological values of 153 grazing goats, pertaining to physiological stage, in the late dry and late wet seasons of Central Trinidad. Goats had lower (P<0.01) haemoglobin (Hb) and packed cell volume (PCV) values in the wet than in the dry season. 41% of goats in the wet season exhibited a non-regenerative anaemia (Hb<80 g/L; PCV<0.22 L/L; reticulocyte count <1%). At one particular farm location lowest forage and serum copper levels and an accompanying highest incidence of non -regenerative anaemia was observed. Also, hemoglobin and packed cell volume values varied (P<0.001) including lymphocyte (P<0.001) counts among growing goats compared with other physiological stages. Significant variations occurred among these stages in the white blood cell count (P<0.05) in goats. A moderate basophilia and eosinophilia was found in both seasons in goats. Highest haemoglobin and packed cell volume, white blood cell counts and lymphocyte values in growing goats compared with other stages was probably age related. Copper supplementation including adequate anthelmintic control is recommended for the prevention of anaemia and to optimize goat and sheep production of Central Trinidad.
