This study was conducted to investigate the effects of 10 weeks supplementation of Quebracho tannins(QT; 0 [control], 100 [QT100] or 200 g/[cow$d] [QT_(200)]) to 30 multiparous postpartum buffalo cows(10 cows per group) on milk yield and composition, blood metabolites and reproductive performance.Supplementation of QT100 had no significant effect on milk yield, whereas QT_(200) decreased(P els decreased(P eld, but no significant effects were found on percentages of milk fat and protein. Contrariwise, yields of milk fat, lactose and milk protein were decreased(P eld were decreased(P < 0.05) with QT100 supplementation. Moreover, QT tended to numerically reduce total number of ovarian follicles, number of small follicles, peripheral progesterone concentration and conception rate. Supplementation of QT_(200) numerically increased number of large follicles, mean diameter of large follicle, number and diameters of corpora lutea. The inclusion of QT_(200) shortened days open(DO) and decreased number of services per conception.Contrariwise, QT did not show significant effects on serum total protein, albumin, globulin, glucose,cholesterol and triglycerides concentrations. Supplementation of QT100 caused an increase(P < 0.05) of serum urea compared with that in control and QT_(200) groups. Generally, QT decreased(P < 0.05) serum creatinine concentration. Therefore, the supplementation of a commercial QT to early lactating Egyptian buffalo cows displayed negative consequences on their productive and reproductive performances.

This study was conducted to investigate effects of supplementing two doses of quebracho tannins (QT;100 or 200 g/cow/d;QT100 or QT200) pre and post parturition to thirty Holstein dairy cows on Dry Matter Intake (DMI), milk yield and composition, blood metabolites and reproductive performance for 12 weeks. There were no significant changes in DMI due to QT at transition period of dairy cows. QT supplementation at either level decreased (P 0.05) the total number of ovarian follicles, number of large follicles, diameter of largest follicle, number of small follicles, number and diameter of corpus luteum, and progesterone concentration. The inclusion of QT increased days open and number of services per conception, which consequently decreased conception rate, compared to the control cows. QT100 decreased (P

ON HYPERSTABILITY OF THE BIADDITIVE FUNCTIONAL EQUATION

引用

Acta Mathematica Scientia 2017年第6期37卷 1727-1739页

作者： Iz-iddine el-FASSI Janusz BRzDEK Abdellatif CHAHBI samir KABBAJ Department of Mathematics Faculty of SciencesIbn Tofail UniversityBP 133KenitraMorocco Department of Mathematics Pedagogical UniversityPodchorazych 230-084 KrakowPoland

We present results on approximate solutions to the biadditive equationf（x＋y,z-w）＋f（x-y,z＋w）=2f（x,z）-2f（y,w）on a restricted domain. The proof is based on a quite recent fixed point theorem in some function spaces. Our main results state that, under some weak natural assumptions, functions satisfying the equation approximately （in some sense） must be actually solutions to it. In this way we obtain inequalities characterizing biadditive mappings and inner product spaces. Our outcomes are connected with the well known issues of Ulam stability and hyperstability.
