ABSTRACTA study to determine the effect of auxin talcum on rooting of air layered malay apple (Syzygium malaccense (L.) Merr. & Perry) was conducted from March to May 2016. The experiment was arranged in a randomized complete block design with three replications, five branches per experimental unit. Auxin talcum treatment consisting of 7 level of auxin concentrations, i.e., (in ppm) 0 (control), 2000 IBA, 4000 IBA, 2000 NAA, 4000 NAA, 1000 NAA + IBA 1000 and 2000 IBA + 2000 NAA in the form of talcum-paste were applied in the upper region of the girdled branches prior to being covered with soil medium. The results showed that after two months, all treatments containing NAA, either singly or in combination with IBA produced 100% rooting, whereas the control treatment was only 22%. The IBA treatments singly at 2000 and 4000 ppm produced 44.4% and 55.6% rooting, respectively. The superiority of NAA upon IBA treatments was also shown by the higher number and length of primary roots as well as earlier root formation. The best treatment for Malay apple rooting was 4000 ppm NAA which produced 33.3 roots, and formed roots three weeks earlier than the control treatment.Key words: air layering, auxin, IBA, NAA, rootingABSTRAKPenelitian ini bertujuan mempelajari pengaruh formulasi pasta auksin yang mengandung IBA, NAA atau kombinasi keduanya terhadap pengakaran cangkok jambu bol (Syzygium malaccense L.)

Abstract This study presents a novel find of a Feed NSPase Enzyme, Natugrain TS, reducing finish pig hemorrhagic bowel syndrome (HBS) mortality. A total of 3,750 weaned pigs (28 kg), (PIC 337 x Camborough), were used in a randomized complete block design with pen as the experimental unit, treatment as the fixed effect, and block as the random effect (25 pigs/pen x 5 treatments x 30 replications). Pigs were blocked by sex and weight and were fed mash corn/soy/DDGs diets formulated to meet or exceed current NRC (2012) recommendations. Treatments were T1= 0 g/MT Natugrain TS, T2= 100 g/MT Natugrain TS, T3= 150 g/MT Natugrain TS, T4= 200 g/MT Natugrain TS and T5= 250 g/MT Natugrain TS. At the finishing phase, Natugrain TS significantly decreased intestinal E. coli log 10 (7.12, 4.95, 4.02, 3.21 and 3.25 log 10, P < 0.05, respectively), significantly decreased intestinal lesion score (0–5 score) (4.21, 4.02, 2.98, 2.25 and 2.26, P < 0.05, respectively). Microbiota was analyzed in fresh, manually collected, rectum fecal samples. Microbiota was separated into prevalent in Natugrain TS control (0) and 200 g/ton. In the control treatment, there was a prevalence of Desulfoyibrio, Oscillospira, Campylobacter, Anearoctruncus, Mogibacterium and Brachyspirae, etc., while in the 200 g/ton treatment there was a prevalence of Synergistales, Burkolderiales, Dehabacteriaceae, Bifidobacterium, Roseburia, Lactobacillus and Bacilli, etc. Natugrain TS significantly decreased mortality (4.8, 3.6, 2.7, 1.9 and 2.1 %, P < 0.05, respectively), significantly decreased specifically HBS mortality (3.50, 1.98, 0.68, 0.40 and 0.46%, P < 0.05, respectively). In conclusion, Natugrain TS changed the microbiome by breaking down arabinoxylans, decreasing intestinal E. coli and intestinal lesion score, changing the microbiota to prevalent Bifidobacterium, Roseburia, Lactobacillus and Bacilli, and Natugrain TS up to 200 g/ton specifically decreasing hemorrhagic bowel syndrome mortality from 3.5% to 0.5%.

Abstract In hot and arid regions, drought stress is considered as one of the main reasons for yield reduction. To study the effect of drought stress, iron spray on the yield and yield components of corn, an experiment was carried out during the crop seasons of 2013 on research Farm in Faizabad of Iran, as a split plot within randomized complete block design with three replications. The main plots with irrigation factor and four levels were considered: level A) 50 ml evaporation from pan evaporation; level B) 100 ml evaporation from pan evaporation; level C) 150 ml evaporation from pan evaporation and level D) 200 ml evaporation from pan evaporation. Sub plots were considered with iron spray in three levels, included level A) 80 g/ha, level B) 130 g/ha and level C) 180 g/ha. The drought stress reduced seed yield, the 1000-kernels weight (TKW), the number of seeds per ear, the number of seeds per row in ear, the number of rows per ear about 39%, 6%, 31%, 14% and 27% less than control treatment, respectively. Using iron, as compared with control treatment, causes the increase of 1000-kernels weight from 295 to 311 g and the increase of seed yield from 5188 to 7078. The results obtained from the present research showed that iron spray has fairly improved the effects caused by drought stress.

Abstract Litter sizes in commercial pig production have increased substantially over recent years; however, farrowing pen sizes have generally not changed over the same time period. The objective of this study was to evaluate the effect of farrowing pen size on piglet pre-weaning growth and mortality. Differences in pen size were created by varying the width of pens of the same length, increasing the creep area available to the piglets. The study used a total of 1,786 litters in a randomized complete block design to compare two Farrowing Pen Size treatments (FPS): Standard (pen width 1.52 m) and Increased (pen width 1.68 m). Litter sizes were equalized across treatments (12.9 ± 1.95 piglets) at 24 h after birth using cross-fostering. Litter weights were collected at birth and weaning (21.3 ± 2.08 d); pre-weaning mortality was recorded. The experimental unit was the litter; models included FPS and replicate. Farrowing Pen Size had no effect (P &gt; 0.05) on litter size at birth (12.8 and 13.0 for the Standard and Increased FPS, respectively), after cross-fostering (12.9 for both treatments), or at weaning (11.2 and 11.3, respectively). There was no effect (P &gt; 0.05) of FPS on total litter or average piglet weight at birth, after cross-fostering, and at weaning. These results suggest no benefit in piglet performance from increasing the width of farrowing pens. As litter sizes continue to increase in commercial production, further research is warranted to re-evaluate the impact of farrowing pen size on pre-weaning mortality.

Abstract Integrating trees into pastures, a practice known as silvopasture, may benefit livestock in the summertime through the provision of shade. The purpose of this project was to compare the behavioral patterns of sheep grazing in silvopastures and open pastures. Black walnut (Juglans nigra L.) and honeylocust (Gleditisia triacanothose L.) based silvopasture systems were compared with open pastures in a randomized complete block design with three blocks over two summers. Behavior measures were recorded within a replicate within a week, and these measures were taken sequentially within three experimental periods. Ewe lambs (n = 3) within each experimental unit were equipped with a wideband audio-recording device to detect prehension events. Time-lapse cameras documented sheep behavior every 60 s. In the silvopastures, the lambs spent over 90% of daylight hours within shade from trees. Lambs in silvopastures spent more time lying down than animals in the open pastures (P ≤ 0.01), while lambs in the open pastures spent more than 2 h longer each day standing (P &lt; 0.0001). Lambs in the black walnut silvopastures spent more time grazing (488 ± 14 min · d−1) than lambs in the honeylocust silvopastures (438 ± 14 min · d−1; P = 0.0493) and lambs in the open pastures (417 ± 14 min · d−1; P = 0.0026). There was no difference in grazing time for lambs in the latter two systems (P = 0.5597). Spectral analysis of the imagery revealed that the lambs in the black walnut silvopastures grazed more frequently than the lambs in the other systems for both years. The acoustic analysis, though limited by recorder durability to 47 complete recordings, revealed no difference in total bites taken per day (P ≥ 0.7222) or in the morning (P ≥ 0.2069), afternoon (P ≥ 0.5816), and evening periods (P ≥ 0.9337). Silvopastures provide an opportunity to improve lamb comfort in the summer.

Abstract This study examined the effect of 1-monoglycerides and 1,2-diglycerides of butyric-, caproic- and caprylic acid (SILOHealth™ 104L [monoglycerides]) and avilamycin on day 14 and 21 post weaning performance of E. coli (GN-Ent and O157:H7) day 5 challenged piglets fed corn/soy diets that met or exceeded current NRC (2012) recommendations. A total of 96, Choice Genetics CG32, piglets were used in a randomized complete block design with pen as the experimental unit, treatment as the fixed effect, and block as the random effect (4 piglets/pen x 3 treatments x 8 replications). Pigs were blocked by sex and weight and were orally dosed with 5 ml (1x109 CFU/g, strain GN-Ent and O157:H7) E. coli d 5 after weaning (Ec). The treatment were: NC with Ec; T1=NC + 3 kg/MT monoglycerides; T2=NC+ 80 ppm avilamycin. Least significant difference was used to compare means of treatment. Mortalities and pen removals were weighed and recorded. The E. coli infection model was effective in causing E. coli mortality of 25% at d14 post weaning and 33% at d21 post weaning in NC. T1 and T2 reduced mortality versus NC at d14 (25, 3 and 0%, P < 0.05) and d21 (33, 4 and 0%, P < 0.05), increased ADG at d14 (203, 255 and 259 g, P < 0.05) and d21 (456, 511 and 515 g, P < 0.05), decreased FCR at d21 (1.90, 1.85 and 1.83, P < 0.05), and decreased intestinal E. coli, log 10 of CFU/g, versus NC (4.1, 2.2 and 2.1, P < 0.05). Monoglycerides and avilamycin performance, mortality and intestinal E. coli log 10 were not significantly different at P < 0.05. In conclusion, the use of monoglycerides improved ADG, reduced FCR, reduced mortality and reduced intestinal E. coli log 10 at day 14 and 21 post weaning versus NC and monoglycerides were not significant different (P < 0.05) than avilamycin.

The effect of different rates of boron application on wheat cv. Bijoy was studied through a field experiment at    Bangladesh Agricultural University (BAU) farm, Mymensingh during 2009-10 rabi season. The BAU farm belongs to    Old Brahmaputra Floodplain agroecological zone (AEZ 9). Texturally the soil was silt loam, with 7.2 pH, 0.81%    organic matter and 0.15 mg kg-1 available boron content. The experiment was laid out in a randomized complete    block design with five boron rates and four replications. Boron rates were 0, 0.75, 1.5, 2.25 and 3.0 kg ha-1, with boric    acid as a source. Every plot received blanket doses of 115 kg N, 25 kg P, 75 kg K and 15 kg S ha-1 from urea, TSP,    MoP and gypsum, respectively. Treatment receiving B @ 2.25 kg ha-1 produced the highest grain yield (4.22 t ha-1) which was statistically identical with that obtained with 1.75 kg B ha-1. However, the crop response curve showed    1.90 kg ha-1 to be the optimum boron rate for the maximization of wheat yield. The lowest grain yield (2.84 t/ha) was    recorded with control treatment. There was a positive relationship between grain yield and number of grains spike-1.   Boron had significant influence on N, P, K, S and B uptake by the crop which, in deed, was more influenced by crop    yield and less by nutrient concentration, except N and B uptake where concentration had more influence than yield.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.10987   J.

Abstract The objective of this study was to compare and explain the variations in the production and nutritive value of canarana erecta lisa grass (Echinocloa pyramidalis Lam.) at different harvest intervals. The treatments corresponded to the cut intervals of 20, 27, 34, 41, 48, 55, 62, and 69 days. The experimental design was a randomized complete block design with three replications. Each experimental unit had 6m2 (3m ×2m). The variables studied included forage production, canopy height, and nutritive value o harvested forage. Forage production varied from 11517 to 12324 kg ha-1; Plant heights from 48.8 to 234 cm; Neutral detergent fiber (NDF) from 68.8% to 71.13%; Acid detergent fiber (ADF) from 36.20% to 44.15%; Crude protein (CP) from 11.43% to 5.85% and in “in vitro” dry matter digestibility (IVDMD) from 63.30% to 47.42%. These values indicated that the nutritive value of canarana erecta lisa was reduced at longer harvest intervals. It is recommended to harvest the grass at 35 days of regrowth favoring productivity, nutritive value and forage digestibility.

Abstract This study evaluated the metabolizable (ME) release of graded levels of phytase when fed to 35 kg pigs on mash corn/soy diets formulated to meet or exceed current NRC (2012) recommendations. A total of 280 male (PIC 337 x Camborough) pigs were used in a randomized complete block design with pen as the experimental unit, treatment as the fixed effect, and block as the random effect (4 pig/pen x 8 treatments x 10 replications). Pigs were blocked by sex and weight. Treatments groups consisted of PC, NC1=PC- 0.17% Ca, - 0.15% aP, -0.02% Na, -200 kcal/kg, T1=NC +1000 FTU/kg phytase+0.15 g/kg NSPase, T2=NC+1500 FTU/kg phytase+0.15 g/kg NSPase, T3=NC+2000 FTU/kg phytase+0.15 g/kg NSPase, T4=NC+2500 FTU/kg phytase+0.15 g/kg NSPase and T5=NC+3000 FTU/kg phytase +0.15 g/kg NSPase. TiO2 was used as the undigestible marker. Feed, rectum grabbed fecal samples were collected at 35 kg pigs. ME was 3407, 3213, 3301, 3329, 3345, 3354 and 3358 Kcal/kg, P < 0.05, respectively. The NC reduced the ME by 194 Kcal/kg versus the PC. 1000, 1500, 2000, 2500 and 3000 FTU/kg released 87, 116, 132, 141 and 145 Kcal/kg, respectively. Least cost formulation reduced net feed costs by $8.63, $9.22, $11.10, $11.90 and $12.39/ton, respectively. In conclusion, Natuphos E by breaking down phytic acid and Natugrain TS by breaking down NSPs released up to 145 Kcal/kg ME in pigs.

Abstract One of the factors limiting crop growth is weeds. The weeds lead to a reduced performance of the crops. Chemical control methods are considered appropriate for controlling weeds. Therefore, in the fight to control weeds in triticale, the performance of the dual-purpose herbicide sulfosulfuron(Apirus®), mesosulfuron + idosulfuron(Atlantis®), metsulfuron methyl+sulfosulfuron(Total®) with surfactant and isoproton + diflufenican(Panther®) from the sulfonylurea group, and narrow leaf herbicides clodinafobpropargyl( Topik®), pinoxaden(New Axial®), diclofop-methyl(Iloxan®), pinoxaden + clodinafob-propagyl (Traxos ®), fenoxaprop-pethyl + mefen-pyper-d-ethyl(PumaSuper®), tralkoksidim(Grasb®) with 1 liter oil, flam-prop-m-isopropyl(Suffix BW®), and control treatment without herbicides were evaluated. The test was carried out in a randomized complete block design with four replications. Spraying was carried out using a back sprayer. For evaluation of ocular damage, the European Weed Research Council (EWRC) standard method was used. According to the performed studies, the narrow leaves of wild oat and barnyard grass were the dominant weeds. Results showed that all herbicide, except the herbicide tralkoksidim, were effective in weed control. The triticale yield was maintained with the use of these herbicides and none of herbicide had an adverse effect on the crop. In the first weeks of herbicide use, the triticale leaves appeared pale but this problem resolved over time. It seems that the herbicides discussed in this paper can be used on the triticale plant.
