Item Effects of functional feed additives on total antioxidant status, lipid peroxidation and blood ındicators of Japanese quails (Coturnix coturnix japonica)(Uludağ Üniversitesi, 2016-04-08) Vahdatpour, Tohid; Monadi-Sefidan, Alireza; Maheri-Sis, Naser; Sandoghchian-Shotorbani, SiamakThe purpose of present research was to investigate effects of a probiotic, a prebiotic and two synbiotics consumption on total antioxidant (TAO) capacity, malondialdehyde (MDA) level, percentages of heterophils, lymphocytes, heterophils /lymphocytes (H/L) ratio as a stress indicator, and albumin, globulin and albumin/globulin (A/G) ratio as a oncotic pressure indicator of blood in Japanese quails. The experimental diets consisted of a basal diet without additive (control), protexin® as a probiotic, fermacto® as a prebiotic, mixed of protexin® and fermacto® as a synbiotic, and Biomin-IMBO® as a other synbiotic, were added to the basal diet and with water were available ad libitum from 1 to 42 days of age of quails. The consumption of these additives had not significant effect on TAO capacity in females and on MDA in both genders, but consumption of prebiotic caused enhancement of TAO capacity of males (P<0.05). The H/L ratio of females fed by additives especially Biomin-IMBO® were lower comparison to control group (P<0.05). The blood albumin was enhanced in males fed by additives especially mixed of protexin® and fermacto® as synbiotic (P<0.05). The A/G ratio was increased by consumption of additives especially with each two synbiotics (P<0.05). The results show that the combination of probiotic and prebiotic as synbiotic is benefit additive for quails feeding. The synergetic effects of synbiotics in improving of live benefit microbial, absorption of necessary nutrients and providing of suitable environment in the gastrointestinal tract are important for health of blood indicators in Japanese quails.Item The effects of ıntramuscular ınjections of vitamin b12 on production performance of dairy cows in early lactation fed dietary supplements of rumen-protected methionine(Uludağ Üniversitesi, 2016-04-08) Safarkhanlou, Morteza; Maheri-Sis, Naser; Ebrahimnezhad, Yahya; Salamatdoust Nobar, RaminTo study the effects of rumen-protected methionine and vitamin B12 as well as their interactions on production performance of dairy cows in early lactation, 16 Holstein cows in early lactation in experiment with randomized complete block design with the 2×2 factorial arrangement used for 42 days. In this experiment, there were four treatments, which in each treatment is placed two cows primiparous and two cows multiparous. Treatments included: 1) The group receiving the basal diet, 2) The group receiving the basal diet with vitamin B12 injections, 3) The group receiving the basal diet with rumen-protected methionine, 4) The group receiving the basal diet with vitamin B12 injections and rumen-protected methionine. The results showed that in the use of vitamin B12 and rumen protected methionine, there is no significant difference between the experimental groups in the dry matter intake, milk production, energy corrected milk, 4% fat corrected milk, fat, protein, lactose, solids, solids-non-fat and urea. Analysis of variance showed that the experimental unit in the second and sixth weeks of experiment there were statistically significant differences in dry matter intake. Use of vitamin B12 can increase the milk production in early lactation, but this increase was not significant and in the case of vitamin B12 associated with methionine this effect is more evident.
