Growth and Development of the Lymphoid Organs as Affected by Inorganic and Organic Zinc in Broilers Chickens
No full textZinc is one of the important minerals that affect the immune system. It should be incorporated in the diet since the effects of deficiency are very pronounced. However, the levels and sources are still unknown particularly in the growth and development of the lymphoid organs. Hence, this study was conducted. Two experiments were conducted following a completely randomized design for a period of 36 days. Experiment 1 utilized zinc oxide while 2 made used of zinc methionine. Results revealed that the different levels of zinc oxide did not affect the average weight and number of lymphatic nodules of the Bursa of Fabricius and thymus. The same organs involuted between 15-28 days and 11-21 days, respectively. The spleen, however, was unaffected. In Experiment 2, it shows that the average weight and number of lymphatic nodules of the bursa of Fabricius and thymus were not affected by the different levels of zinc methionine. Bursa involuted from days 8-28 while thymus, between 11-21 days. Increasing spleen's weight pattern was noted only in the control group beginning on day 11 and peak on day 28. The study concludes that the growth and development of the lymphoid organs were not affected by zinc inclusion in the diet. It recommends that supplementation must be accompanied by good management practices
Effects of Different levels of Zinc in the Performance and Meat Zinc Contents of Broilers
No full textZinc is one of the most deficient microminerals. For poultry, NRC (1994) recommended 40 ppm only but, commercial feeds contain more than 100 ppm resulting to toxicity. Zinc oxide is commonly used inorganic forticant but, its safety is questionable compared to organic counterpart. Generally, the study aimed to determine the effects of different levels of zinc oxide and zinc methionine in the performance of broilers and their meat content at 36 and 42 days. To address the latter, two experiments (experiment 1, zinc oxide and experiment 2, zinc methionine) were conducted and gathered data were analysed using ANOVA. Results showed that in both experiments, the performance and meat zinc contents were not affected but, the parts were affected showing highest zinc content in the liver, followed by the thigh and legs, and the wings. Lowest amount was noted in the breast. Fortification, up to 36 days of feeding was found to be enough. In fortification programs, it is recommended to use organic minerals
Soybean-Genistein as Endocrine Disruptor on Estrous Cyclicity and Ovarian Follicular Development in Albino Rats (Rattus norvegicus)
No full textEndocrine disruptors are chemicals that interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife. One example of endocrine disruptor is phytoestrogen which is a group of naturally occurring compounds that have been reported to cause fertility problems in animals. The major phytoestrogen in soy products is genistein, which has potent estrogenic activity both in vitro and in vivo. Previous findings have demonstrated that the control of primordial follicle development and subsequent folliculogenesis appears to be mediated by local production and action of specific paracrine factors. Preliminary studies also have shown that steroid hormones like estrogen play a critical role in the onset of primordial follicle assembly. These findings led us to further look into the effects of genistein on estrous cyclicity and ovarian folliculogenesis specifically on pre-antral and antral follicular development including their possible effects on ovarian morphometry of sexually matured female albino rats. The objectives of the study was to determine the effects of genistein on estrous cyclicity and ovarian folliculogenesis specifically on pre-antral and antral follicular development including their possible effects on ovarian and uterine morphometry of sexually matured female albino rats. Furthermore, the study elucidated its effect on the apoptosis of granulose and theca cells resulting to follicular atresia. A total of 24 female albino rats approximately 2-3 months of age of almost the same size were used in this study
Awareness, knowledge, attitude, and practices (A-KAP) assessment of the One Health approach in health sciences education webinar series participants in select universities in the Philippines
No full text# Background
A three-day One Health training program for undergraduate and graduate students, as well as professionals in One Health-related fields, was conducted by the Philippine One Health University Network (PhilOHUN), in collaboration with the Southeast Asia One Health University Network (SEAOHUN), through a webinar series. To measure the impact of the training on the awareness, knowledge, attitude, and practices (A-KAP) related to the topics covered in the program, this study was conducted.
# Methods
A quasi-experimental design was employed to evaluate the effect of the One Health training program on the A-KAP of the participants. An online questionnaire developed based on the content of the training modules was administered to the participants before and after the training program. The attendees who accomplished both the pre- and post-training A-KAP assessment questionnaire were included as study participants; of the 225 attendees, 119 respondents qualified. The difference between the pre- and post-training mean A-KAP scores of participants was determined using paired t-test.
# Results
Findings showed that the Awareness of the participants (P\0.05) after taking part in the training.
# Conclusions
The significant differences in awareness and knowledge suggest that the training modules contain relevant topics, which were effectively transmitted during the program. For Attitude and Practices, it may be premature to determine the impact of a single activity, although it is expected that these will change over time. Nevertheless, the training program can be used as a springboard for introducing One Health concepts to a wider audience and a continuing initiative to influence the development of appropriate attitudes and practices for current and future One Health practitioners
A Study on Knowledge, Attitudes, and Practices on Rabies in the Philippines
No full textIn 2007, the Philippine government passed the Anti-Rabies Act to address rabies in the country. However, rabies is still a major public health concern in many provinces. This study aimed to evaluate the knowledge, attitude, and practices (KAP) of residents on rabies, the Anti Rabies Act, and responsible pet ownership (RPO) in Pampanga, Philippines. A cross-sectional survey was done from October 2017 to February 2018 in 92 randomly selected barangays in the province. Questionnaires were adapted from similar studies. Logistic regression was used to identify factors associated with KAP. Results showed that most people have good knowledge of the Anti-Rabies Act, RPO, and moderate knowledge of rabies. Their attitude toward rabies was appropriate, and on RPO, moderate. The RPO practices by most dog owners were good and moderate for most cat owners. Moreover, the subjects’ area of residence was a significant factor in their knowledge of RPO, and pet ownership status was a significant factor in their RPO attitude. In general, respondents showed satisfactory knowledge; however, there is a need to intensify information and education campaigns in rural areas
