Effects of graded levels of crude glycerine addition to diets on growth performance, carcass traits and economic efficiency in broiler chickens

The aim of the current study was to evaluate the effects of graded levels of crude glycerine addition to diets on growth and economic performance, carcass yield, organ weights and moisture levels of meat in broiler chickens. For this purpose, a total of 270 one day old male chicks (Ross 308) were randomly divided into 3 equal groups which fed with isocaloric and isonitrogenous diets with graded levels (0%, 5% and 10%, respectively) of crude glycerine. Each of experiment group was constituted by 5 subgroups with 18 birds each. The birds had ad libitum access to feed and water until termination of the experiment at d 42. Results indicated that 5% dietary crude glycerine addition improved body weight, body weight gain and feed conversion ratio compare with birds fed with basal diet at d 42 (P<0.01). Similarly, dietary 10% crude glycerine supplementation also increased growth performance and improved FCR in broiler chickens at 28th and 42nd days of experiment (P<0.05 and P<0.001, respectively). Moreover, birds fed with 5% dietary crude glycerine had showed over 20% higher relative economic efficiency compare than birds fed basal diet. As a conclusion, dietary crude glycerine addition improved growth and economic performance and Feed Conversion Ratio of broilers in both supplementation levels

EFFECTS OF MOLDSTOP (R) ON AFLATOXICOSIS IN QUAILS

ALTINTAS, Levent/0000-0002-5148-723XWOS: 000262248800015This study was conducted to evaluate the toxic effects of anatoxin (AF) oil the growth performance of quails, and to determine the preventive efficacy of MOLDSTOP (R) (calcium formate, calcium propionate, citric acid, sorbic acid, acetic acid, and carrier). A total of 60 one-clay-old quails (Coturnix coturnix japonica) of both sexes were equally divided into four experimental groups each comprising of five replicates of three birds. The supplementation of diet with AF decreased significantly (P<0.001) the feed consumption. The 0.5% addition of MOLDSTOP (R) to the AF diet did not significantly prevent or reduce negative effect of AF on feed consumption at any time period. Light microscopic examination demonstrated that the addition of MOLDSTOP (R) did not decrease flat deposition Caused by the toxin, and besides, an electron microscopic examination indicated the reorganisation in the endoplasmic reticulum and increase in the number of ribosomes and polisomes compared to the AF plus MOLDSTOP (R) group. The data indicated that the addition of MOLDSTOP (R) to diets containing AF did not prevent the negative effects of AF observed in the quail
