    Effect of Immunocastration Vaccine Administration At Different Doses on Performance of Feedlot Holstein Bulls
    (2018) Öztürk, Yahya; Bolacalı, Memiş
    The aim of the study is to determine the effect of immunocastration vaccine administration at different doseson fattening performance of feedlot Holstein bulls. In this research, 94 Holstein male calves assigned to the 4treatments. Control group; 1 mL of 0.9% saline solution was subcutaneously injected to intact bulls on 1st and60th days of the feedlot as placebo. On the same days of the feedlot, Immunocastration vaccine (Bopriva®) attwo doses of 1 mL and 1 mL for Trial-1 group, 1.5 mL and 1.5 mL for Trial-2 group, 1.5 mL and 1 mL forTrial-3 group were subcutaneously injected to bulls. The feedlot lasted 180 days. Immunocastration vaccineadministration at different doses did not affect the live weights (LWs) and cold carcass yields of feedlotHolstein bulls (P>0.05). However, it reduced fattening performance between 61-120 days (P<0.05) and 1-180days (P<0.01). As a result, it was decreased the fattening performance that administration of Bopriva® atdifferent doses as a GnRH vaccine in Holstein male bulls; whereas it was determined that numerically increasein average daily live weight gain was found in the Trial-2 group than the other groups to which theimmunocastration vaccine was applied.

    Effect of Non-Genetic Factors on The Reproductive Performance and Milk Yield Characteristics of Hair Goats
    (2019) Bolacalı, Memiş; Öztürk, Yahya; Yılmaz, Orhan; Küçük, Mürsel; Karslı, Mehmet Akif
    The aim of this study was to determine the potential effect of non-genetic factors on certain productioncharacteristics of Hair goats raised under semi-intensive management and dry- sub humid conditions, and toinvestigate phenotypic correlations between these traits. A generalized linear model was used to investigate theeffect of non-genetic factors on gestation length (GL), number of services per conception (NSPC), lactationlength (LL), lactation milk yield (LMY) and daily milk yield (DMY), while the Chi-square method was used toevaluate other fertility parameters. The pregnancy rate, birth rate and single-birth rate in the Traditional Groupwere higher, while the infertility rate and NSPC were lower, than those in the Artificial Group (P<0.001).Furthermore, it was determined that LL, LMY and DMY increased (P<0.001), the NSPC decreased (P<0.001),and birth and twinning rates fluctuated (P<0.01) as age increased. The best fertility and milk yield characteristicswere in the ?5 year-old-goats and live weights of 45.0-49.9 kg. In addition, it was determined that kid yield wasincreased in the goats synchronized with intravaginal sponges impregnated with fluorogestone acetate and inthose bred via the traditional method.

    Investigation of some morphological traits of boer x hair f1 crossbred and pure hair goat kids raised in semi-intensive conditions
    (Universidad de la Frontera, 2017) Bolacali, Memis; Öztürk, Yahya; Yilmaz, Orhan; Küçük, Mürsel; Karslı, Mehmet Akif
    The aim of the study was to determine various morphological characteristics from birth to the age of 150th day of Boer x Hair goat F1 crossbred (BH) kids and pure Hair goat (HG) kids raised in semi-intensive conditions and reveal factors such as the effects of genotype, dam age, dam’s live weight, year, birth type and sex on this parameter. This study was applied between the years 2011-2012 in Çatak in the Van region and between the years 2013-2014 at the Yuzuncu Yil University Research and Practice Farm. Various body measurements; wither height, back height, rump height, sacrum height, body length, chest length, chest depth, chest circumference, circumference of leg, cannon bone circumference, chest width, front-rump width, mid-rump width were determined 29.8, 28.4, 28.7, 26.2, 28.7, 17.0, 13.3, 30.4, 26.9, 5.2, 5.9, 6.0, and 8.7 cm at birth, respectively; 43.8, 43.8, 44.6, 40.6, 43.6, 22.2, 19.3, 51.7, 41.4, 6.6, 9.2, 9.3, and 11.3 cm at 60th day, respectively; 56.1, 53.4, 54.4, 47.5, 53.3, 27.3, 24.1, 61.4, 49.6, 7.3, 10.6, 11.1, and 13.2 cm at 150th day, respectively for BH kids; 27.3, 25.9, 29.3, 25.3, 27.1, 15.9, 12.3, 29.0, 21.3, 5.1, 5.0, 5.6, and 7.4 cm at birth, respectively; 40.4, 40.1, 42.9, 37.6, 40.5, 22.3, 18.4, 48.1, 36.4, 6.0, 7.9, 9.1, and 10.8 cm at 60th day, respectively; 50.3, 49.2, 51.0, 45.7, 50.4, 27.5, 22.9, 57.3, 43.4, 6.5, 9.5, 10.7, and 11.9 cm at 150th day, respectively for HG kids. When all of the data was considered, it was concluded that the BH kids are much better than the HG kids for both morphological and zoometric values. © 2017, Universidad de la Frontera.
