GROWTH PERFORMANCE OF BROILERS FED MICRO-PELLET BOOSTER DIET ON THE FIRST SEVEN DAYS OF BROODING Thea Pamela S. Ponce, Veneranda A. Magpantay, Edwin S. Luis
Abstract
One hundred day-old broiler chicks were raised for 35 days to determine their growth performance when fed micro-pellet booster diet on the first week of brooding. Booster mash (BM) and micro pellet booster (MPB) were fed to two separate groups at brooding stage. Birds were fed similar diet thereafter. Production parameters were compared using t-test. Results showed that body weight and feed consumption were significantly better in broilers given MPB. Feed conversion ratio (FCR) of MPB fed broiler was significantly better during the brooding stage compared to BM but FCR for the whole production cycle was unaffected. Likewise, livability and dressing percentage were not significantly different. Performance efficiency factor showed that MPB diet improved the grade but the difference was insignificant. Moreover, results of the proximate analysis of feeds indicated that the BM and MPB diets had different nutrient densities which could have affected the performance. Income over feed and chick cost was found to be 10% lower for broilers given MPB diet. Results showed that the use of MPB during the first seven days significantly increased the body weight and feed consumption. However, its use as a replacement to BM is proven to be uneconomical under Philippine condition.

PARTIAL SUBSTITUTION OF COMMERCIAL SWINE FEEDS WITH MALUNGGAY (Moringa oleifera) LEAF MEAL UNDER BACKYARD CONDITIONS Sonia P. Acda, Hazel Grace D. Masilungan, Babylyn A. Moog
Abstract
Two feeding trials were conducted to evaluate the potential of malunggay (Moringa oleifera) leaf meal (MLM) as partial substitute for commercial hog pre-starter and starter diets of weaned pigs. Sixteen and 15 crossbreed weaned pigs were distributed randomly to four and three treatments in feeding trials A and B, respectively, following a completely randomized design. Commercial feeds served as the control diet in both feeding trials; substituted with 2, 3 and 4% MLM for treatments 2, 3 and 4, respectively in feeding trial A. In B, substitution with MLM was increased to 5 and 10% for treatments 2 and 3, respectively. Results showed no significant differences among treatments in all performance parameters measured. The average body weight, average daily gain, average daily feed intake and feed conversion ratio of pigs fed diets with up to 10% MLM were statistically comparable to those fed 100% commercial feeds. Therefore, the commercial hog pre-starter or starter feeds could be partially substituted with MLM up to 10% without detrimental effect on the performance of weaned pigs. When malunggay is readily available in the backyard where the animal raiser could prepare the MLM, the feed cost to produce a kilogram body weight gain could be reduced by as much as PhP 4.28 to PhP 6.84/kg BWG with 10 and 4% MLM, respectively. COMPARATIVE PERFORMANCE OF SMALL, MEDIUM AND LARGE SWINE COMMERCIAL FARMS Renato S. A. Vega, Elpidio M. Agbisit, Jr., Dyna D. Andam, Beatriz R. Garcia, Anne Valera, Art T. Calud, Edwin C. Villar Abstract

Twenty four commercial farms with three-year performance data were grouped into small (n=5; mean=133 sow level), medium (n=4; mean=331 sow level) and large (n=15; mean=1,295 sow level) farms to compare farm productivity and efficiency. Using General Linear Model, the effects of farm sizes, year, quarter, months nested within quarter, interactions of farm sizes by year and by quarter were determined. The desirable (preferably high values) parameters include average birth weight (ABW), average weaning weight (AWW), average 30-day weight (A30DW), adjusted 180-day weight (A180DW) and average daily gain (ADG). The undesirable (preferably low values) parameters include adjusted 90-kg age (A90KA), average age of regular slaughter hogs sold (AARSHS), farm efficiency, feed cost per kilo of live animals sold...
