The influence of age and the reproductive status to the blood indicators of the ewes

Abstract

Abstract. The influence of age and the reproductive status has been researched in the blood serum of 75 Merinolandschaf ewes. We have detected statistically very high concentrations of Ca in the blood serum of pregnant and non- pregnant ewes comparing to those in lactation, while the opposite way has been noticed for the concentrations of P-inorganic and Na. Statistically much higher concentrations of K have been found in the lactating and non-pregnant ewes comparing to the pregnant ones. Statistically much higher concentrations of albumin and cholesterol have been detected in the blood of pregnant ewes comparing to the non-pregnant ones, while the opposite way has been noticed for the concentrations of total proteins. GGT activity was statistically much higher in the blood of ewes in lactation comparing to the non-pregnant ones and the CK and ALT activity in the pregnant ones comparing to those in lactation. The ewes up to one year old had statistically very significant high concentrations of P-inorganic, Na, Fe, glucose, AP, GGT, CK activities and in the older ewes the concentrations of cholesterol and total proteins. Due to that, it is necessary to, before the metabolic profile specification of ewes, take into consideration age and the reproductive status of the animals. For the age there have to be taken the concentrations of P-inorganic, Na, Fe, glucose, cholesterol and total proteins as well as AP, GGT, CK activities and for the reproductive status the concentrations of Ca, P-inorganic, Na, albumin, total proteins as well as the ALT, CK, GGT activities. These researches give basis for the regular therapy application and carrying out the prevention of the metabolic disturbances of ewes in the aim of reducing economy losses.

Blood Metabolic Profile and Certain Hormones Concentrations in Egyptian Buffalo During Different Physiological States

“…Serdaru et al (2011) found that, serum enzymes (AST, ALT and AlP) were significantly lower in the lactating buffaloes groups. Abdulkareem (2013) found that in buffaloes, AST activity was numerically higher (96.06±8.75-102.61±11.62 Unit LG 1 ) during postpartum periods in comparison with its value at calving (90.06±8.04 Unit LG 1 ) indicating that hepatic metabolism might be more stressed and tissue catabolism was more normal range pronounced during this period (Antunovic et al, 2004). However, because enzyme activities were within the normal range, integrity and functionality of liver tissue was obviously maintained during these periods.…”

Influence of physiological stage and parity on energy, nitrogen and mineral metabolism parameters in the Ouled Djellal sheep in the Algerian Southeast arid area

“…In case of pregnancy toxemia, blood glucose levels are lower than 20 mg/dl (Nelson and Guss, 1992). Antunovié et al (2004) noted high blood glucose in empty females compared to pregnant ones. This was also reported in cows (Otto et al, 2000), and in Sahal's goats studied by Sandabe et al (2004).…”

“…In a subsequent study, they described significant differences of uremia between empty and pregnant females (Antunovié et al, 2004).…”

“…A significant number of authors describe the mineral and biochemical indicators in the blood of the sheep (Pastrana et al, 1991a, b;Shinde et al, 1995;Klinkon and Zadnik, 1997) reported by Antunovié et al (2004). But, only a very small number of authors report about the influence of the reproductive status (Baumgartner and Penthaner, 1994;Ramos et al, 1994;EL-Sherif and Assad, 2001;Antunovié et al, 2002Antunovié et al, , 2004 and the parity as the important prerequisites for the biochemical indicators' interpretation in sheep.…”

In order to establish the metabolic profile of the sheep, it is necessary to know the influence of reproductive status as well as the parity.…”
