Mycotoxin binders potential on histological of ovary mice exposed by zearalenone

Aim: This study was conducted to examine the potential of mycotoxin binder in ceasing zearalenone (ZEN) effect on mice reproduction. ZEN mycotoxin can induce reactive oxygen species that may cause damage and cell death. ZEN is estrogenic so that it may affect the reproductive organs failure. Materials and Methods: Mycotoxin binder administration to female mice exposed to ZEN was aimed to count the number of primary follicles, secondary follicles, tertiary follicles, de Graaf’s follicles, and the corpus luteum (CL). Negative control group (C) was not exposed to ZEN and without the administration of mycotoxin binders, while positive control group (C+) was exposed to 0.1 mg/mouse/day ZEN and without the provision of mycotoxin binders. Treatment groups (T1, T2, T3) were exposed to 0.1 mg/mouse/day ZEN and mycotoxin binders 0.5; 1; 2 mg/BW/day. Results: ZEN and mycotoxin binders administration was conducted for 10 days. The number of primary follicles, secondary, tertiary, de Graaf’s follicles and CL in negative control (C−) was 14.2±1.36, 11.2±0.28, 6.5±0.53, 7.5±0.74, and 2.3±0.35. The number in positive control (C+) group was as follows 7.1±0.12, 3.7±1.17, 3.8±1.21, 1.5±0.62, and 2.3±0.34. Results in treatment 1 (T1) were as follows 6.2±0.16, 5.2±0.16, 3.6±0.16, 2.6±0.19, and 2.6±0.10; in treatment 2 (T2) 7.8±0.28, 5.8±0.53, 3.7±0.26, 2.7±0.26, and 2.5±0.10; and in treatment 3 (T3) 8.4±0.34, 8.4±0.34, 4.6±0.34, 4.5±1.01, and 3.4±0.23. Conclusion: The number of follicles and CL more in line with increasing doses of mycotoxin binders. Required more than 2 mg/mouse/day mycotoxin binders to inhibit the effects of ZEN so that its can maintain the number of primary follicle, secondary follicle, tertiary follicle, the de Graaf’s follicle, and the number of CL in the ovary of ZEN-exposed female mice (Mus musculus).

Honeybee product therapeutic as stem cells homing for ovary failure

Aim: Complexity of the method of isolation, cultivation in vitro and the expensive cost of transplantation process of stem cells, it would require an innovation to homing and differentiation of stem cells and increase folliculogenesis. The stem cells homing was achieved through the provision of food or beverages derived from natural materials like honeybee product. Through honeybee product, there will be homing of stem cells and accompany with the sources from the body itself will take place in regeneration of the ovary. Materials and Methods: Female rats model of degenerative ovary was obtained through food fasting but still have drinking water for 5 days. It caused malnutrition and damage of the ovarian tissue. The administration of 50% honeybee product (T1) was performed for 10 consecutive days, while the positive control group (T0+) was fasted and not given honeybee product and the negative control (T0−) not fasted and without honeybee product. Observations were taken for homing of stem cells, raised of folliculogenesis, differentiation of stem cells, and regeneration of the ovarian tissue using routine H&E staining. Results: Homing of stem cells shown the vascular endothelial growth factor and granulocyte colony-stimulating factor expression; enhancement of folliculogenesis was indicated by an increase of follicle dee Graaf count; enhancement of differentiation of stem cells was indicated by growth differentiation factor-9 expression; and regeneration of ovarian tissue indicated by intact ovarian tissue with growing follicles. Conclusion: Honeybee product can be induced endogenous stem cells in regeneration of ovary failure due to malnutrition.

The improvement of eggs quality of Mojosari duck (Anas javanica) with soybean husk fermentation using cellulolytic bacteria of Spodoptera litura

Aim: This study was aimed to improve the quality of the eggs of Mojosari duck (Anas javanica) through complete feeding containing soybean husk was fermented using cellulolytic bacteria of Spodoptera litura. Materials and Methods: This study consisted of three stages: The first stages, isolation and identification of cellulolytic bacteria from S. litura; the second stage, the fermentation of soybean husk through the application of bacterial cellulolytic isolate from the first stage; and the third stage, the application of the best complete feed formulation from the second stage to Mojosari duck. Results: There are four dominant bacteria: Bacillus sp., Cellulomonas sp., Pseudomonas sp., and Cytophaga sp. Furthermore, the best reduction of the crude fiber of soybean husks is the use of Cellulomonas sp. bacteria. The final of the study, the quality of the eggs of Anas javanica, was improved, as indicated by cholesterol decrease from the yolk without the decrease of egg weight and eggshell thickness, although the decrease in egg yolk color was inevitable. Conclusion: Soy husk fermentation using cellulolytic bacteria of S. litura was added to complete feeding can be performed to improve the quality of the eggs of Mojosari duck.

Case Study : Dystocia on Beef Cattle in Kunir Regency of Lumajang District, East Java, Indonesia in 2015 and 2016

Dystocia defined as difficulty of birth. Cattle that experienced dystocia characterized by extended processing time of birth, difficult, and impossible to do without help of human stem. This study aimed to determine the number and causative factor of dystocia in beef cattle in Kunir sub district, Lumajang district. Data acquisition used primary data and secondary data. Primary data was obtained from direct observations about management of maintenance, then interviewed the farmers in Kunir sub district. Secondary data was data obtained from the recording belongs to animal health technical officer. The results showed that the prevalence of dystocia in Kunir district, Lumajang district as many as 63 cases or 11,6 % of 543 births. The result of the research is analyzed using chi square (χ2) method on SPSS 20.0 program and risk factors that increase the incident of dystocia were IB semen which greater than the cattle site, the position of the fetus and inertia uteri can result in weakness of the catrle at the age of older and more likely to give birth. Key words : Dystocia; beef catlle
