Öğe Effects of Dietary Humic Acid and Saccharomyces cerevisiae on Performance and Biochemical Parameters of Broiler Chickens(Academic Journals Inc, 2008) Celik, Kemal; Uzatici, Ahmet; Akin, Adil ErdemOne hundred and fifty broilers (1-day-old) were randomly allocated to 4 treatments. each of which had individual pens of 50 chicks and were used to investigate the effects of humic acid (HA) Saccharomyces cerevisiae (SC extract (YE), 2 x 10(8) cfu g(-1)) oil growth performance and immunity. All animals received the same basal diet based on corn and soybean meal and while HA was added to the basal diet at 0.25% and YE 0.25%, respectively. The following diet treatments were applied: (1) Basal diet + 0 additives, (2) Basal diet 0.25% HA kg of feed (3) Basal diet 0.25% YE kg of feed (4) Basal diet 0.25% HA+0.25% YE kg of feed. Each experimental group was fed ad libitum with its own diet for 42 days, During the experiment the chicks were reared at conventional ambient temperature (from 30 degrees C reducing to 21 degrees C by 3 degrees C/week) and relative humidity of 60-70%. Light was provided 24 h in a day. Performance data of each replicate was determined weekly during the experiment. All chicks were slaughtered when end of 6 weeks. Blood samples from 30 birds in each group was collected by branchial vein and were analyzed for Serum biochemical values, enzyme activities and performance characteristics were measured. Body weight, body weight gain, feed intake and carcass weight were positively influenced (p<0.05) by HA supplementation (0.25%) during the experiment. Difference among the groups in terms of gizzard, liver and biochemical parameters such as WBC, Heterophil, Lymphocyte, Monocyte, RBC, HCT were not statistically important among different treatment groups (p<0.05). But, Glucose and BUN levels were significantly decreased in groups HA and YE (p<0.05). ALP, ALT, Fe, Ca, P were not statistically significant among groups.Öğe Effects of replacement of soybean meal by cottonseed meal on laying performance and haemoglobin levels in practical diets for breeder japanese quail, Coturnix coturnix japonica(Asian-Australasian Association of Animal Production Societies, 2004) Erturk, M. Mustafa; Ozen, Nihat; Celik, KemalA 16 week feeding trial was conducted to evaluate the effects of replacement of soybean meal (SM) by extracted cottonseed meal (CSM) on laying performance and haemoglobin levels in practical diets for breeder Japanese quail (Coturnix coturnix japonica). One hundred ninety two quails (6 weeks old) were divided randomly into eight groups. The diets were isocaloric containing 2,900 kcal/kg of ME and isonitrogenous (% 20 crude protein) as fed basis. SM was replaced by 0, 2.5, 5.0, 7.5, 10.0, 12.5, 15.0 and 17.5% of CSM, respectively. Average egg production (quail day, %; quail house, %), egg weight (g), daily feed intake (g/bird), feed efficiency ratio (g feed/g egg) data indicated no significant differences among the treatments; while, blood haemoglobin levels (% g Hb) of 7th (15.0% CSM) and 8th (17.5% CSM) group were lower than the control (0% CSM) diet (p<0.05). This experiment indicated that 17.5% CSM could replace SM (providing 44% of SM protein) in practical diets of breeder Japanese quails without any significant impairment on laying performance.Öğe Effects of vitamin a supplementary in the feed to reduce toxic effects of aflatoxin B1 on Japanese Quails (Coturnix coturnix Japonica)(Asian Network for Scientific Information, 2003) Denli, Muzaffer; Celik, Kemal; Okan, FerdaA study was conducted to determine the efficacy of the antioxidant vitamin A, for reducing aflatoxicosis in Japanese quail (Coturnix coturnix Japonica) from hatch to 35 d of age. Sixty Japanese quail chicks were randomly divided into four groups, three treatments and one control. Control group was fed a basal diet while the treatment diets were supplemented with vitamin A (15,000 IU/kg feed), vitamin A (15,000 IU/kg) + low level of aflatoxin B1 (100 •g/kg) or aflatoxin B1 (100 •g/kg). The liver was swollen and a bright yellow color; microscopically fatty metamorphosis, necrotic areas and infiltration of polymorphonuclears were observed in aflatoxin B1 group and was not seen in any other groups. Compared to control, aflatoxin B1 (AFB1) reduced body weight gain (BWG) and feed conversion rate (FCR) by 9.3 and 7.6 % respectively. The addition of 15,000 IU/kg of vitamin A without aflatoxin B1 improved quail growth performance. Dietary vitamin A had affect on BWG and feed consumption (P<0.05) and reduced the toxic effects of AFB1, addition resulted less toxicity in the liver and kidney than AFB1 group. FC was found significantly important during third and fourth weeks in vitamin A and AFB1 added group (P<0.05) FCR was also better than AFB1group. The concentration of liver function enzymes serum glutamic pyruvic transaminase (GPT), serum glutamic-oxaloacetic transaminase (GOT), alkaline phosphatase (ALP) increased when AFB1 was added to the diet, whereas the supplementation of the diet Vitamin A partially decreased this negative effects. These results demonstrate that vitamin A plays a complex role in the process of chemical aflatoxicosis and when added at 15.000 IU/kg in the diet can provide protection against the harmful effects of AFB1 for experimental period in Japanese quail. © Asian Network for Scientific Information 2003.Öğe The effects of chlorsulfuron and feed containing ascorbic acid on some serum parameters in Albino rabbits(Medwell Journals, 2014) Uzatici, Ahmet; Coskun, Baver; Celik, Kemal; Duman, CanAs all around the world, pesticides are used in the country to control the harmful organisms. As is known, however, use of pesticides takes a toll on humans, animals and the environment health-wise and insensible and intensive use causes residues in food, soil, water and air. Even though the use of pesticides creates an increase in quantity product-wise, they are potential toxic materials for humans and animals. In this research, New Zealand Albino rabbits (75 days old, 2 kg average live weight) were given chlorsulfuron and vitamin C through feed for 45 days, their liver enzyme activities were monitored and it was checked whether or not the liver was damaged. In the research, levels of GGT and ALK.P in the serum samples received from trial group animals were observed to be sensible in comparison to the control group (p<0.05). © Medwell Journals, 2013.Öğe The efficacy of mycotoxin-detoxifying and biotransforming agents in animal nutrition(Academic Press Ltd-Elsevier Science Ltd, 2020) Celik, Kemal[Anstract Not Available]
