Water table management is suggested to overcome these issues, if adopted by producers. But such adoption decisions often depend on the financial returns to producers. In this study, financial returns of a controlled drainage system were estimated over a subsurface drainage system using a private accounting stance. The BMP provided an additional return to producer of CAD $10,287 per ha over the life of the project, associated with a benefit-cost ratio of 1.6, making it financially desirable on economic grounds. </span></p> Mariela Marmanillo, Suren N.

(Black Austrolorp x Barred Playmouth Rock) https://j.ideasspread.org/index.php/as/article/view/1084 <p>The present study was conducted at Bataan Peninsula State University Abucay Campus to evaluate the growth performance and hematological profile of <em>Gallus domesticus</em> Linn. (Black Austrolorp x Barred Playmouth Rock) chicken fed formulated diets of varying inclusions of lesser duckweed (<em>Lemna minor</em> Linn.). Three formulated treatments diets of homogenous crude protein level were prepared: 0% duckweed (control), 10% duckweed, and 15% duckweed inclusion. Five chickens (average weight 202.5 g) per replicate were reared in a single factorial experiment and the feeding trial was carried-out for three months. Chicken fed diet containing 15% duckweed meal treatment had significantly (<em>P</em> &lt; 0.05) higher body weight (1,425.88 ± 55.24 g) compared to chicken fed normal diet (1,223.48 ± 174.47 g). Mean cost to produce a kilogram of meat was significantly cheaper in the treated diets (<em>F</em> = 4.82; <em>P</em> &lt; 0.05). Mean values of hematological variables were not significantly different among treatments.</p> Hermogenes M. Paguia, Rina Q. Paguia, Jesus Rex A. Pinsel, Steve Zaballa, Abigail G.

Few studies were conducted in terms of the agronomic characteristics of the Madre de Agua prior to utilization as feeds and most studies conducted were mainly conducted to feed monogastric animals. The study intends to produce data for the agronomic characteristics of Madre de Agua as planted and produces a shaded portion of the upland area in BPSU Abucay Campus, Abucay, Bataan. The following parameters were gathered; Plant Height, Leaf to Stem Ratio, Herbage Yield, and Dry Matter Yield and Soil Analysis. Moreover, the following baseline data were used: the area with an elevation of 141.1 feet above sea level with an average rainfall of 296.45mm and temperature ranges from 26<sup>o</sup>C to 30<sup>o</sup>C during the duration of the study. Fertilizer requirements are based on the result of BSWM soil analysis (30g/tree ammonium phosphate, 169g/tree Urea, and 4kg/tree organic fertilizer) applied during and after transplanting with adequate irrigation.&nbsp; The study was carried out using systematic random sampling for plants. The result of agronomic characteristics in upland conditions showed that the average plant height of Madre De Agua was 110.50 cm, Leaf to Stem Ratio was 65.82%/34.18% per plant, herbage yield was 556.50 grams per plant, dry matter yield (oven dry) was 87.57% per plant. The established area for the production of the Madre de Agua will be utilized to provide a continuous source of feed to small ruminants and other monogastric species for future research in animal production.</span></p> Abigail Garcia Abuan, Christian M.

Using Waxed Paper Bags https://j.ideasspread.org/index.php/as/article/view/1114 <p>The present study was conducted in Brgy. Dangcol, Balanga City, Bataan to evaluate the effect of bagging the whole panicle (cluster) of carabao mango fruit with waxed paper bag as compared to traditional method of bagging and without bagging in terms of fruit yield and quality as well as in cost-benefit analysis. Results revealed that fruits bagged per cluster using waxed paper (T3) obtained the highest number of marketable fruits (130.60) and highest total weight of 34.21 kg while the number and weight of XL fruits with no bag (T1) were significantly higher as compared to those bagged in cluster using waxed paper (T3). Insect damage was observed in fruits bagged per cluster using waxed paper bag (T3) while there is a scab in fruit with no bag (T1). Meanwhile, there is a wind scar observed in the two bagging methods (conventional bagging method and fruits bagged per cluster using waxed paper bag). All bagging treatments were comparable in terms of physical and chemical characteristics except for peel color which is lighter green in bagged fruits. In terms of income, mango fruits bagged per cluster using waxed paper bag (T3) had the highest gross income of PhP 3,056.27 while the highest net income and ROI was recorded in fruits bagged in conventional method (T2) earning PhP 616.09 per tree with 27.23% ROI. The conventional method (T2) also obtained the lowest cost per tree (PhP 2,262.36) while the lowest cost per kilogram (PhP 73.05) and cost per fruit (PhP 19.14) was recorded in mango trees bagged per cluster using waxed paper bag (T3).</p> Cherrilyn E Ventura, Leslie R.

Once the gravity of the fertilizer in the storage box is greater than the suction of the electromagnetic sucker, the fertilizer discharging board is automatically opened for fertilizer discharge, and the metering pulse signal is accumulated once. Meanwhile, the fertilizer guide plate is driven by the electromagnetic commutator to reverse the material, and then another storage box is started for fertilizer storage and metering. In this approach, online detection of fertilizer flow can be realized by repeatedly guiding and reversing and metering the incoming fertilizer. According to the single metering fertilizer quality and the number of metering pulse signals, the fertilization amount can be calculated in real-time.The performance of the device was verified by bench test. The test results indicated that: The established fertilizer application detection model is a quadratic function (R<sup>2</sup>&gt;0.98), and the verification error was less than 3.73% in the detection of alternating cycle fertilizer discharge; the coefficient of determination (R<sup>2</sup>) and the root mean square error (RMSE) reached 0.992 and 9.858 respectively, indicating high detection accuracy of the device is.</p> Yang Chuan Ke, Li Jia Nian, Wang Xiao Cheng, Li Dao Ran, Wang Guo Xuan ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://j.ideasspread.org/index.php/as/article/view/1122 Fri, 28 Oct 2022 00:00:00 +0800 Implementation Selection to Increase Body Weight Fancy Mice https://j.ideasspread.org/index.php/as/article/view/1119 <p class="text"><span lang="EN-US">Use laboratory animal for research purposes is often used especially in the fields of health research, food, agriculture, and livestock. The laboratory animal that is often used as research objects include rabbits, mice, guinea pigs, monkeys, and rats. Research in the field of livestock in animal breeding requires a long time to research and a large number of animals so mice can be used to apply it. The goal of research is determine effect of the selection program on parameters of mice body weight including weaning weight and adult weight. The research was held with Fancy mice keeping and selection implementation of weaning weight 21 days age (WW21) and 35 days age (AW35) which starts from 0 generation until 2<sup>nd</sup> generation. The data used in the selection of Fancy mice on 0 generation until 2<sup>nd</sup> generation each of 327 tails, 330 tails, and 263 tails. The result of the selection of Fancy mice to WW21 increased obtained WW21 G0 to G1 is 3.69 gram and WW21 G1 to G2 is 2.09 gram. Selection of Fancy mice to AW35 that result in AW35 G0 to G1 is 5.14 gram and AW35 G1 to G2 is 4.92 gram, which means selection is impacting increased WW21 and AW35 Fancy mice.</span></p> Meireni Cahyowati, Endang Baliarti, Sumadi Sumadi ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://j.ideasspread.org/index.php/as/article/view/1119 Fri, 11 Nov 2022 00:00:00 +0800
