Effect of Flushing on the Kid Growing in the Hairy Goats
(Centenary University, 2017) Kor, D.; Demirel, M.
In this study, growing kids of Hair goats fed level of maintenance ration (MR), MR x 1.25, MR x 1.50 and MR x 1.75 were evaluated for 40 days including 20 days before mating period and 20 days after that. The birth weights of single female kids (3.08 kg) from goats fed the level of MR were found lower than single female kids from other feeding groups, significantly (P<0.05). The average daily gain (ADG) of twin male kids (0.161 kg) from goats fed the level of MR x 1.50 was observed higher than twin male kids from other feeding groups, significantly (P<0.05). Difference among the groups in the survival rate of the kids was not significant. However, the survival rate of kids from the goats fed level of MR remained at 86.36% while that of kids from the goats fed level of MR x 1.75 was determined 100%. In present study, the effect of flushing in the Hair goats has not become very decisive on the kid growing in terms of observed criterions. As a result, designing energy and protein levels of rations at more extreme points, utilizing different feedstuff in the rations and studying with genotypes that have higher genetic capacity in terms of fertility in researches should be suggested. © 2017, Centenary University.

The Effects of Different Types of Antioxidants (Se, Vitamin E and Carotenoids) in Broiler Diets on the Growth Performance, Skin Pigmentation and Liver and Plasma Antioxidant Concentrations
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2016) Karadas, F.; Erdogan, S.; Kor, D.; Oto, G.; Uluman, M.
This study investigated the effects of the addition of different antioxidants to broiler diets on their live performance, liver antioxidant composition and concentrations, immune response, and meat and skin color. A total of 945 three-day-old Ross 308 broiler chicks of both genders were randomly allocated to one of nine dietary treatments (n=105), with three replicates 35 chicks per pen, as follows: T1: control (commercially available corn-and soybean-based broiler diet); T2: selenium (control+0.5 mg/kg Sel-PlexTMSe yeast); T3: vitamin E (control+200 mg/kg Kavimix-E-50 a-tocopherol acetate); T4: lutein (control+100 mg/kg 5% Lutein Beads XB); T5: lycopene (control+100 mg/kg 5% Lyco Beads XB); T6: canthaxanthin (control+25 mg/kg 10% Carophyll (R) Red); T7: apoester (control+25 mg/kg 10% Carophyll (R) Yellow); T8: lutein+zeaxanthin (control+25 mg/kg Xamacol (R)); and T9: beta-carotene (control+100 mg/kg 10% Rovimix (R)). Feed (starter, grower, developer and finisher phases) and water were provided ad libitum for 42 days. Body weights, feed intake, feed conversion values and plasma carotene concentrations were recorded weekly, and liver antioxidant concentrations were recorded at the end of the experiment. Newcastle disease (LaSota) vaccination was performed on day 22. HI titers were measured on days 14, 21, 35 and 42 to determine the effects of the antioxidants on the immune system. The addition of selenium, vitamin E, and carotenoid supplements to the commercial broiler diet significantly increased antioxidant accumulation in the liver and the plasma. All antioxidants assessed significantly improved the immune response. Selenium and vitamin E supplementation also significantly improved total carotenoid concentrations in the plasma. The carotenoids enhanced skin and meat color. None of the supplements tested influenced growth (p>0.05).
Is It Possible That Pecan Nut (Carya Illinoinensis) Shell as an Organic Material May Be an Alternative Feed Additive
(Centenary University, 2018) Kor, D.; Karadaş, F.; Karageçili, M.R.
Consumption of natural foods has become important day after day and organic food production has also become popular as a result of increasing demand of consumer. Therefore; industry and science world, for organic animal food production focuses on the waste products generated in plant production and the availability of these natural products in animal nutrition has been increasingly discussed in recent years. The shell which is released during the production of pecan nut (Carya illinoinensis) is considered an organic waste material. Although there have been a lot of research on the pecan nut, in recent years the number of research articles associated with the nutritional composition and some phytochemical properties of pecan nut shell that related human and animal health is low and this shows that it is just beginning to be a subject of scientific work in this area. It has been underlined that pecan nut shell has high fiber content, antioxidant and antimicrobial properties according to reported data in the recent publications. In the view of such data, it may be thought that pecan nut shell can be used feed additive, like a prebiotic, supporting immune system and stopping the development of some pathogens. In addition; it is also interesting to note that there is the protective function of the pecan nut shell which suppresses the growth of some microorganisms that can cause health problems in humans due to the meat in cooked and preserved inappropriate conditions. Thus, it is concluded that pecan nut shell as a natural and a new product has potential subjected to research area of animal nutrition as feed additive. © 2018, Centenary University.
