Purpose - Feeds comprise the majority of swine production expenses, and it has been the goal of livestock farmers to acquire feeds with the best value. This paper identified and analyzed the feed supply sourcing practices and strategies of commercial swine farms in a major hog-producing municipality in Bulacan, a province in the northern Philippines. Design/Methodology/Approach - Small, medium, and large commercial swine farms from Sta. Maria municipality in Bulacan province, 34 in all, were the study subjects. A descriptive method of inquiry/investigation was employed in the study using questionnaires in data gathering. Data was analyzed through mean, mode, frequency counts, and cross tabulation while a Chi-square Test of Independence and Cramer’s V were also used to scrutinize relationships between significant data results. Findings - Four feed supply sourcing strategies were identified in the study, namely (1) self-production of feeds (64.7% of the farms), (2) buying unbranded feeds (23.5%), (3) buying branded feeds only for piglets’ pre-starter and booster feeds while self-producing the rest (23.5%), and lastly, (4) buying feeds from commercial feed mills (11.8%). As the scale of an operation increases, self-production of feeds becomes more prominent due to its overall lower cost, while for farms with a smaller scale of operation, buying unbranded feeds is the more dominant practice due to its lower capital requirement and the relatively lower cost of unbranded feeds compared to those branded. Balance (quality and price) is the decision criterion mostly used by swine farms when choosing feed suppliers. Scale of operation, type of ownership, and years in operation are significant variables associated with the feed sourcing strategy used by commercial swine farms. Research Implications - Few studies focus on the feed supply sourcing of swine farms. Many of the recent studies focus on production, success factors, profitability, technologies, and new farming systems. This study addresses the feed supply sourcing research gap by focusing on the different practices and strategies pertaining to the feed supply sourcing of commercial swine farms. Such insights have crucial and strategic trade implications on the part of feed ingredient and feed suppliers in the country, and it defines specific opportunities for government support as well.

Biomechanical and Anatomical Validity of the Short Posterior Arch Screw

Objective: This study was conducted to clarify the validity of the short posterior arch screw (S-PAS). The S-PAS is inserted only in the pedicle-analogue portion of the posterior arch. The S-PAS screw length is almost half that conventional C1 lateral mass screws inserted via the posterior arch (via-PAS). S-PAS reduces the risk of vertebral artery injury (VAI) because it never reaches the transverse foramen. Although the biomechanical validity of various C1 lateral mass screws (C1LMS) analyzed in young specimens have been published, that of unicortically inserted C1LMS such as the unicortical Harms screw, S-PAS, and via-PAS for elderly patients is concerning because of the high prevalence of osteoporosis in the elderly. Methods: Nine fresh frozen cadavers (average age at death, 72.1 years) were used for pullout testing. The bone mineral density of each specimen was evaluated using quantitative computed tomography. Results: The pullout strength of via-PAS (1,048.5 N) was significantly greater than that of the unicortical Harms screw (257.9 N) (p<0.05). The pullout strength of S-PAS was 720.3 N, which was also significantly greater than that of the unicortical Harms screw (p<0.05). Conclusion: The via-PAS and S-PAS are valid surgical options, even in elderly patients. Along with sufficient biomechanical strength, the S-PAS screw prevents VAI.

Bladder cancer (BC) is one of the most common human cancers. There is an interest in controlling and treating BC and other types of cancer via the use of natural substances and/or combination chemotherapy. Modified forms of pectin have been reported to possess anticancer bioactivity related to the interaction of galactosyl, a main component of pectin, with galectin-3, a carbohydrate-binding protein that is overexpressed on many types of cancer cells. In this study, the antiproliferative effect on BC of novel modified pectins extracted from olives was evaluated. Pectoliv extracts, with high polyphenol content associated to polysaccharides rich in pectin, exhibited an important antiproliferative capacity in vitro against four human BC cells lines, RT112, T24, J82, and SCaBER. Pectoliv treatment reduced the expression of galectin-1 and galectin-3 and significantly inhibited the agglutination of erythrocytes. Thus, Pectoliv may have the potential for development as a novel galectin-3 inhibitor.
