Objective: This study was conducted to screen scrotal hernia in domesticated swine from selected breeders in the Philippines. This defect is associated with a cytosine to thymine mutation in the BCL-2 associated X protein (BAX) gene of swine. Methods: Genetic screening was done by DNA extraction followed by amplification and digestion using polymerase chain reaction-restriction fragment length polymorphism, amplifying the 416 bp region of the BAX gene that was subjected to digestion using the Ear I enzyme. Sequencing was also conducted to validate the results. Results: Results revealed that out of 538 samples tested, 411 (76.4%) of the samples were found to be normal whereas the remaining were carriers of the mutation in which 80 (14.9%) were heterozygous mutants and 47 (8.7%) were homozygous mutants. Pietrain breed was found to have the highest incidence. Conclusion: Having a scrotal hernia eliminates the chances of using the boar as a breeder stock because the following generations arising from it would most likely exhibit herniation. It is therefore advised to establish a genetic screening method for Scrotal Hernia in the Philippines to eliminate the negative gene from the herd.

Nutritional status of macro minerals (Ca, Mg and P) in goats grazed on the native pasture was investigated for 2 years in Luzon Island, Republic of the Philippines. Three regions in Luzon Island (Los Banos; Southern area, Munoz, Nueva Ecija; Central area and Baguio; Northern area) were objected to collect the samples of forages and blood of goats on the pasture. The average values in Ca, Mg and P contents of all the forage samples were 0.29-1.32, 0.13-0.56 and 0.15-0.45% of dry matter, respectively, and these figures almost exceeded the required dietary levels for sheep. There was no obvious changes in mineral content of forages between the seasons of rainy and dry, or among regions. In blood Ca level, more than a half of goats (57.9%) without supplement showed the level below the lower limit, and the low level was not improved even when they fed with some supplemental concentrates. The plasma levels of Mg and P were satisfactory, referring to the lower limit of normal level in goats. It is, therefore, necessary to decide the requirement and to establish a most suitable technique for supplying Ca to grazing goats in Luzon Island.

우리나라 장미산업의 국제화에 대비하여 필리핀 코르딜레라 고냉지 지역에서 생산된 장미의 품질, 수량 및 우수 품종을 연구, 소득 분석을 요약하여 아래와 같이 산업화의 기초자료를 얻기 위해 본 실험을 수행하였다. 절화 내 질적 실험에서는 대비종에 비해 특히 'Jacaranda' 품종은 개화기간 46일, 13일정도의 꽃받침 휨 정도보다 짧은 것으로 나타내므로, 광질, 조사기간 및 온도 등이 영향을 제일 많은 영향을 받는 것으로 볼 수 있었다. 절화 시 'Vicki Brown'와 'Jacaranda' 품종은(개화기간 49일, 13일 꽃 받침 휨 정도 이내) 중, 단초 절화로 분류되는 다른 품종에 비해 단축되는 경향을 보았다. 'Jacaranda', 'Vcki Brown', 'Golden Times', 'Champagne', 'Osiana' 및 'Queen Elizabeth' 품종은 전정에서 46.7일에서 50.77일까지 조기 개화되었으나 'Tineke' 품종은 전정 41일 후에 꽃 받침 휨 정도가 0.5cm에 이르게 되어 개화형성이 늦어짐이 뚜렷하였다. 여기에서 상위 10품종 장미의 순수익은 'American Orange' 품종 $77072, 'Yellow Island' 품종 $39322, 'Frosty Pink' 품종 $27130, 'Champagne' 품종 $24516, 'Coral Pink' 품종 $23992, 'Lara Pink' 품종 $22961, 'Lara Orange' 품종 $17856, 'Grand Gala' 품종 $17645, 'Golden Times' 품종 $20163 및 'Lady X' 품종 $19452 등이다.
