In order to investigate the effect of combined animal-chemical fertilizer and zeolite on the biochemical properties of two cultivars of red bean (Phaseolus vulgaris L.), a factorial experiment with three factors in the form of a randomized complete block design with three replications was implemented in climatic conditions of Azna city in Lorestan province in spring of 2016 and 2017. Cultivar factor included two cultivars Goli (creeping) and Akhtar (standing); Animal-chemical compound fertilizer agent in five levels including 100:0, 75:25, 50:50, 25:75 and 0:100 Livestock:chemical ratio and zeolite agent in four levels including non-application of zeolite and consumption of 3, 6 and 9 tons zeolite per hectare. Livestock manure was obtained from rotten sheep manure and chemical fertilizer was obtained from urea. The results showed that with increasing zeolite consumption, shoot proline decreased but grain yield (2199 kg / ha) increased. In both Goli and Akhtar cultivars, the highest amount of shoot iron (375 and 403 mg / kg, respectively), grain iron (102 and 111 mg / kg, respectively) and grain yield (2341 and 2630, respectively) Kg / ha) from 50:50 animal treatment: chemical and six tons per hectare of zeolite was obtained, but the highest potassium content of shoots (1.40 and 1.39%, respectively) in flower cultivar from 0: 100 animal treatment: Chemical and non-use of zeolite; While in Akhtar cultivar, 0: 100 livestock: chemical and six tons per hectare of zeolite were obtained. In total, Akhtar cultivar with the application of 50:50 animal manure: chemical fertilizer and six tons per hectare of zeolite is recommended to achieve maximum grain yield and grain enrichment.

Coccidiosis is one of the important parasitic diseases in poultry industry. Diagnosis insubclinical cases is difficult, and usual OPG measurement method is not valuable forcorrect assessment of infected farms. This study tries to achieve the new factors forassessment of lesion scores via lesion scoring parameters along with maduramycincoccidiostat administration.75 Ross strain broiler chicks were randomly divided into 3groups including: negative control group, positive control group and maduramycin testgroup OPG rate evaluated at the day of 23 in 3 groups, and then 5 chicks were randomlysacrificed in each group and lesion score indices plus chick weight, the hole weight ofgastrointestinal tract, length and weight of small intestine were examined. Tukey andSheffer statistical tests, Pearson correlation and 't' tests were used for analysis of results.OPG rate in maduramycin test group were significantly decreased in comparison withpositive control, also the weight mean of positive control were significantly decreased incomparison with negative control and maduramycin test group (P < 0.001). The mean oflesion scores in maduramycin group were significantly decreased in comparison withpositive control. With regard to results, two indices of gut looseness, and gut mucosaldestruction rate should be considered for lesion score evaluation and necessity of effectiveanticoccidial drugs administration is recommended by farmers in prevention and controlof disease.
