    EFFECT OF SUPPLEMENTATION OF OVINE OVIDUCTAL CELLS WITH LH AND OESTRADIOL-17 beta ON EMBRYO DEVELOPMENT
    (INDIAN VETERINARY JOURNAL, 2008) Ciftci, H. B.; Zulkadir, U.; Boztepe, S.; Ozturk, A.; Dag, B.; Yetisir, R.
    In sheep, towards the end of follicular phase of the oestrus cycle, plasma concentration of E 2 increases and this increase is followed by an increase in LH secretion. The secretion of E 2 and LH can affect the secretary function of the oviductal cells and hence facilitate embryonic development in vitro. Therefore, the aim of this study was to measure the effect of supplementing the oviductal cells with Luteinizing Hormone,(LH) and oestradiol 17 beta (E(2)) on embryo development.

    Genetic analysis of Test Day Milk Yields of Brown Swiss cattle raised at Konuklar State Farm in Turkey, using MTDFREML
    (SOUTH AFRICAN JOURNAL OF ANIMAL SCIENCES, 2009) Zulkadir, U.; Aytekin, I.
    A total of 3696 Test Day Milk Yield (TDMY) records of Brown Swiss cows raised at Konuklar State Farm in the Konya Province of Turkey were used for estimating phenotypic and genetic parameters for TDMY. The phenotypic and genetic parameters were estimated by an MTDFREML programme using a Single Trait Animal Model (STAM). The model included additive direct effects, maternal permanent environment and errors as random effects, parity, year and season of calving as fixed effects, and days in milk (DIM) as a covariate. Genetic parameters and breeding values for TDMY in kg were estimated. The TDMY least square mean was estimated as 15.64 +/- 5.82 kg, and the direct heritability (h(a)(2)), maternal heritability (h(m)(2)) and the repeatability (r) of TDMY were calculated as being 0.28 +/- 0.09, 0.04 +/- 0.54 and 0.31 +/- 0.01, respectively. The effects of parity and year-season of calving on TDMY were significant.
