  One 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), 2x108 cfu g-1) on 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°C reducing to 21°C by 3°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.

  One of the important modifications that have been made in animal feeding is the usage of the natural feeds and the feed supplements having any negative impact on human health. Therefore, there has been an increase in the usage of vegetable extracts together with the feeds in the broiler feeding. It is indicated that the vegetable extracts ameliorates the feed consumption and the benefitting from the feed and consequently have the positive impact on the live weight. This study is carried out in order to ascertain the usage opportunities of the artichoke extract (Cynara scolymus) that has positive productive effects on broilers' feed and the vegetable extract named Bedqen 40 that includes choline chlorite and their metabolic impacts on liver enzymes. The study was conducted while using 100 Ross 308 hybrid chicks for 42 days as control and experimental groups. In terms of the live weight at the end of the experiments, there is a significant statistical difference between the groups (p = 0.0425). In respect to the daily increase of live weight, the difference between the experimental group and the control group is statistically negligible (p≥0.1104). There is no difference in terms of the liver enzymes between the experimental group and the control group both at the start and the end of the experiment (p≥0.1792).

  As 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).

  This research was conducted to determine if there is a possibility of Poultry Manure (PM) ensiling with Apple Pomace (AP) and the possibility of the usage of produced silage as a nutritional stuff in the feeding of beef cattle. As a first step, PM, the weight of it was reference unit was blended with the AP at a ratio of 25 and 50%, ensilaged and the quality of the silage was examined. By the 60th day of the ensilaging process, pH values were 3.97 and 4.05 in the samples collected from 25 and 50% PM containing silage materials, respectively. The analyses of the same samples for the lactic, acetic and butyric acid ratios revealed as in 25% PM containing silage 1.727, 1.052 and 0.294% and in 50% containing silage 0.852, 0.693 and 0.877%, respectively. The second stage of the experiment was designed as 111 days of feeding trial and conducted with 8-10 months old Brown-Swiss male cattle with an average live weight of 333 kg and they were allocated into 3 groups, each of which composed of 8 animals. One of the groups was kept as a control. Silages containing 25 and 50% PM was provided as roughage to the remaining group, group I and II and they were used as trial groups. The control group was fed with a ration consisted of pelleted concentrate and wheat straw only. Lack of nutrients in the silages provided to the trial groups was completed with the similar concentrate and wheat straw given to the control group. At the end of the trial, the average live weight of the bulls in the control group, groups I and II were 452,456 and 461 kg and their daily weight gains were 1063,1108 and 1153 g, respectively. A statically significant difference with respect to daily weight gain was not observed among the groups. Throughout the experiment, the amount of dry matter for 1 kg weight gain in order of groups was 6.92, 6.74 and 6.27 kg and the cost of weight gain was 6578, 4775 and 4096 Turkish Liras, respectively. The examinations of rumen fluid for ammonium and urea nitrogen at the end of the feeding trial showed that the values were 10.6, 13.4 and 15.1 mg/100 mL and 12.3, 13.6 and 24.0 mg/100 mL in the groups, respectively and differences of these results were statistically significant (p<0.01). However, since the above values are below the toxic levels and toxic effects of these substances were not observed in the animals. Ammonia and urea nitrogen were also analyzed in the blood. At the end of the experiment while the blood ammonia values were 0.30, 0.34 and 0.52 mg/100 mL, respectively the respective urea nitrogen values were 5.75-9.30 mg/100 mL. The values for both parameters were higher in the animals of experimental groups compare to those of control group (p<0.01). Above results showed that preparation of silage by the addition of 25 and 50% PM to the AP is possible and the produced silages were consumed by the beef cattle without any negative effects on the weight gain and feed consumption and also provides an economic food supply.
