Publication The effect on carcass characteristics of different silage types used in the rations of fattening lambs(Hellenic Veterinary Medical Soc, 2023-10-01) Şengül, Ömer; Ak, İbrahim; ŞENGÜL, ÖMER; AK, İBRAHİM; Ziraat Fakültesi; Zootekni Bölümü; KEJ-7788-2024This study was carried out to investigate the effects on carcass characteristics of lambs fed with dif-ferent silage types(corn silage, sunflower silage and their mixtures) and their mixtures at different levels. In the study, rumen volatile fatty acids levels and rumen pH of the lambs used in the experiment were determined at the beginning and end of fattening. For corn silage and sunflower silages, aerobic stability and lactic acid bacteria and yeast-mold counts were determined. In the treatment, 40 Kivircik male lambs aged 2.5-3 months were used as animal material. Lambs were divided into 5 different silage groups (100% corn silage, 75% corn+25% sunflower silage, 50% corn si-lage+50% sunflower silage, 25% corn silage+75% sunflower silage, 100% sunflower silage) and it was planned to have 8 lambs in each group. The lambs were housed in individual compartments during the experiment and the animals were individually fed. Silages were given to the lambs ad libitum and in addition to silage 700, 900 and 1400 g concentrated feed were given daily between 0-21, 21-42 and 42-56 days, respectively. As a result, it can be said that feeding with different silage types does not have a significant effect on carcass characteristics of lambs, and silages prepared with corn silage, sunflower silage and their mixtures can be used successfully in lamb fattening.Publication Effect of royal jelly on puberty of ewe lambs(Polish Soc Veterinary Sciences Editorial Office, 2021-09-01) Sengül, Ömer; İbrahim, A.k; Emsen, Berna; ŞENGÜL, ÖMER; AK, İBRAHİM; Ziraat Fakültesi; Zootekni Bölümü; 0000-0001-5078-2002; AAH-2915-2021; EZK-6483-2022In this study, we investigated the effect of royal jelly on the puberty of female 1/4 Romanov x 3/4 Morkaraman crossbred lambs. Royal jelly was applied in two ways: orally and intravaginally. The rate of estrus as well as the day and time (in hours) of estrus were observed and determined by real-time ultrasonography (for pregnancy) and laparoscopic surgery (ovary examination). Three groups of lambs were observed. The first group, consisting of 15 female lambs, was treated intravaginally; in the second group, 15 female lambs were treated orally; and the third group, which served as control, consisted of 10 ewe lambs that were not treated with royal jelly. Estrus rates in the intravaginally and orally treated groups were 13% and 20%, respectively, whereas the control group showed no estrus activity. However, estrus interval in both groups was observed 3-5 days after the withdrawal of the treatment. All the animals had an active ovary when observed during estrus activity by ovary examination. Yearling 1/4 Romanov-bred ewes respond positively to royal jelly application. Increasing the doses and extending the duration of royal jelly application might yield better results.Publication Effect of dietary protein levels on some haematological and production parameters of breeding ostriches(Indian Veterinary Journal, 2004-03-01) Aydın, Coşkun; Zaugg, S. N.; Ak, İbrahim; AK, İBRAHİM; Galip, Nurten; Veteriner Fakültesi; Fizyoloji Ana Bilim Dalı; 0000-0002-6351-0740Nutrition is an important aspect of rearing birds commercially. Feeding costs contribute approximately 70-80% of total cost of ostrich production (Brand et al., 2000). There are still many gaps in the information on nutrient requirements of ostriches as well as utilization of nutrients in the different feed stuffs (Smith, 1995).A number of clinical and nutritional disorders can be assessed from clinical haematology and blood chemistry (Okatie-Eboh et al., 1989). Non-specific avian values are inadequate because hematological and biochemical status is a reflection of many factors including. species, age, diet and management (Bowes et al., 1989).This study was conducted to evaluate the effect of dietary protein levels on some haematological parameters and production performances of ostriches. In addition, this study begins the process of establishing reference values for haematological profiles of breeding ostriches in Turkey.Publication Effects of in-ovo injection of glutamine on late-term embryo development, hatchability, one-day old chick quality and small intestine morphological traits in broilers(Eugen Ulmer Gmbh Co, 2020-01-17) Sözcü, A.; Ak, İbrahim; AK, İBRAHİM; Ziraat Fakültesi; Zootekni Bölümü; CBP-9147-2022This study investigated the effects of in-ovo injection of glutamine on late term embryo development, hatchability, one-day old chick quality and small intestine morphological traits in broilers. Hatching eggs were obtained from a Ross 308 breeder flock at 36 weeks of age and were injected with glutamine into the air sac on day 17 of incubation. Six treatment groups were created as follows: negative control (no injection), positive control (injected with only distilled water), and four groups injected with different doses of glutamine dissolved in 0.5 ml distilled water, dose 1: 20 mg; dose 2: 40 mg; dose 3: 60 mg; dose 4: 80 mg. On day 20 of incubation, embryo weight, yolk absorption and embryo body and leg length were found to be highest in embryos given 40 mg of glutamine (P < 0.01). Chick hatching weight and relative chick weight were highest in the 40 mg treatment (dose 2) (45.9 g and 72.2% respectively). At hatch, villus growth in the duodenum, jejenum and ileum was stimulated by glutamine injection at dose 2 (40 mg). These findings showed that a 40 mg glutamine in-ovo injection gave the optimum increase in embryonic growth and liveability, chick quality and villus development in broilers.
