L. S. Palomar ABSTRACT Muscovy duck and native chicken were used to compare the acceptability of smoked duck cured at 2 vs 3 days, 55° vs 70° salinity and with vs without refrigeration in a clay pot. Results indicate that 2-day curing is better than 3-day curing in smoked duck with 55° salinity. It is …

S. C. Bantugan and J. R. Escano ABSTRACT Bone meal supplement slightly improved the reproductive performance of melengestrol acetate (MGA)-synchronized native cattle. Synchronized estrus was higher among cows (80%) and among heifers (90%) in the bone meal supplemented group compared to 80% among cows and 60% among heifers in the control group. The overall breeding …
R. M. Gapasin ABSTRACT The reaction of Golden Yellow cassava differed at varying inoculum levels of Meloidogyne incognita and M. javanica. Initial populations of approximately 10,000 and 20,000 eggs of M. incognita significantly reduced (P = 0.05) the root and top weights of cassava over the control; however, reduction in tuber weight was not significant …

J. C. Bouwkamp and L. E. Scott ABSTRACT Total yield and yields of sweet potatoes measuring 5-9 cm diameter (No. I size) and 2.5-5 cm diameter (No. 2 size) were found to be highest at the closest spacing studied (30 cm between plants, 90 cm between rows) after a full season’s growth (120 days). This …
