Sciences VétérinairesTags : profil biochimique vache laitière tarissement lactation alimentation biochemical profile dairy cow drying lactation diet ??????? ???????????? ???? ???? ????? ????? ??????? Index. décimale : 636 Sciences Vétérinaires Résumé : Our study has as main objective to establish a biochemical profile of blood and milk with different dietary intake (dry, early lactation). To make usual values available in the hand of veterinary practitioners so they can use them as an early diagnostic tool.
A second objective was to determine the relationship between dietary and quality of milk.
This research was conducted on 20 Holstein cows, aged 3 to 7 years, clinically healthy, multiparous from two dairy farms in the province of Constantine.
The blood of 15 days interval samples were conducted during the period from the
beginning of drying up until 3rd month of lactation. These samples have concerned some
blood parameters (glucose, triglycerides, cholesterol, total protein, albumin, urea,
creatinine, ALT, AST, calcium and phosohore).
A milk monthly interval sampling was carried out during the first months of lactation. These relate to the determination of certain biochemical parameters "" milk protein, lactose"" and the analysis of some physicochemical parameters “acidity, density, pH”.
Proteinemia, créatinimie and plasma ALT showed significant variation (p < 0.05) between the two farms of the study.
The triglycédérimie, the chlestérolémie, the protéinimie, uremia, crétinimié, serum calcium, plasma ALT activity and AST, the rate of protein substances and lactose rate showed significant variation across different stages of the study. While blood sugar, serum albumin, serum phosphate, acidity, density, pH, and the fat rate showed no significant variation.
The results obtained on the basis of the parameters indicate that the biochemistry of milk and blood may be an early detection tool of dietary errors.

Sciences VétérinairesTags : profil biochimique profil hormonal vache laitière gestation post partum biochemical profile hormonal profile dairy cow pregnancy ?????? ????? ??????? ?????? ???????? ???? ???? ??? ??? ??????? Index. décimale : 636 Sciences Vétérinaires Résumé :
The aim of this study is to determinate the usual values of some biochemical and hormonal parmeters during the gestation and during the period of post partum, in order to help practitioners to use this paraclinic tool.
A second objective is to study the effect of the physiological stage on certain blood
metabolites in dairy cattle. The present research was conducted on 10 cows, of Prim Holstein breed aged from 3 to 5 years, clinically healthy, multiparous, from two dairy farms located in the wilaya of Constantine.
Samples were realized at different physiological stages (beginning, middle and end of
gestation, prepartum, a day after calving and a month post partum). These samples focused on the assay of certain biochemical parameters (urea, creatinine, albumin, total proteins, cholesterol, calcium and phosphorus) and hormonal parameters (progesterone, oestradiol, prolactin)
Uremia, albunemia, proteinemia, cholesterolemina, calcemia, progesteronemia as well as the plasmatic concentration of oestradiol varied significantly (p<0.01). The plasmatic concentrations of creatinine showed slight variations (p=0,198 > 0,01), whereas those of prolactin did not show any variation (p=0,41 >0.05).
The obtained results on the base of blood parameters (biochemical and hormonal), indicate the necessity to monitor the metabolic profile of animals, in order to determinate the nutritive state, and to take preventive measures towards health troubles to increase the productivity.
