Abstract Senturklu et al., (2018) defined merits of delayed feedlot entry while grazing in an integrated crop-livestock system (ICLS). In a three-year follow up study, yearling steers (n = 144) grazed either an ICLS or a native range system (NR). After 177.9 days, free-ranging ICLS and NR steers were fed cover crop hay bales 43.6 days to determine transition period bale-grazing on finishing performance, carcass measurements, and system net return. ICLS and NR gains did not differ (P = 0.24). ICLS 43.6-day bale grazing gain was greater (1.38 vs. 0.80 kg; P = 0.01). Feedlot arrival weight was greater for ICLS compared to NR (569.3 vs 530.1 kg; P = 0.04) and fed 95.7 days. Systems end weight (P = 0.19), gain (P = 0.57), ADG (P = 0.06), and gain cost (P = 0.71) did not differ. ICLS steer hot carcass weight (HCW: 444.8 vs. 419.2 kg; P = 0.03) and fat depth (1.35 vs. 1.17 cm; P = 0.04) were greater. NR steer dressing percent (62.48 vs. 61.83 %; P = 0.01) and muscling ratio to HCW (3.96 vs. 3.81 sq. cm.; P = 0.007) were greater. Choice quality grade did not differ (98.6 vs. 98.6; P = 1.00). Annual cow and steer winter feed cost were $752.00. ICLS grazing cost for NR was $115.30, pea-barley $74.98, unharvested corn $108.87, and cover crop $58.82 totaled $357.97 compared to $207.77 for the NR system. ICLS and NR steer bale and protein-energy supplement cost was $110.47 vs. 103.05, finishing cost $310.57 vs. 313.67 (P = 0.84), and total expense was lower for the NR system ($1531.01 vs. $1376.49). Carcass value was greater for the ICLS steers compared to NR steers ($2013.93 vs. $1921.67; P = 0.03). ICLS and NR systems’ net returns were ($482.92 vs. $545.18). NR system net return was $62.26 greater.

Field studies were conducted for three years in each of two successive experiments and analyzed to determine net return from stale seedbed plantings of soybean. Treatments in the first experiment were early May and late May/early June plantings in seedbeds that had combinations of tillage at various times between harvest and planting, incorporation of trifluralin, or no preplant tillage. Treatments in the second experiment were irrigated and nonirrigated stale or no-till seedbed plantings with weed control treatments that included POST cultivation plus combinations of preplant foliar-applied (PFA) glyphosate, PRE metribuzin, and POST herbicides. Results indicate that 1) early planting of soybean resulting from use of a stale seedbed will result in higher net returns when irrigation is used, 2) use of a wheat cover crop does not justify the expense, 3) soybean planted in a no-till seedbed will result in net return similar to that from plantings in fall-tilled, spring-tilled, or prepared seedbeds, 4) use of only a PFA herbicide plus POST cultivation in a stale seedbed planting where competitive weeds such as common cocklebur appear later will result in a significant reduction in net returns, and 5) use of PRE herbicides in conjunction with PFA herbicide and POST cultivation in a stale seedbed planting will result in the highest net return with the least input.

Economic analysis compared the returns of cropping systems and management practices for production of fall lettuce (Lactuca sativa L.) and spring cantaloupe (Cucumis melo) following summer cover crops. The cover crop treatments included: cowpea [Vigna unguiculata (L.) Walp.] incorporated into the soil in the fall, cowpea used as mulch in the fall, sorghum sudangrass [Sorghum bicolor (L.) Moench] incorporated into the soil in the fall, and a bare ground control. Lettuce and cantaloupe were managed using conventional, integrated, and organic practices. The effect of each cropping system and management practice on crop yield, cost of production and net return was determined. In 1999 and 2000, yield and net return were greatest for cantaloupe and lettuce when the cowpea cover crop was incorporated into the soil before planting. The effect of crop management practice varied with type of cover crop. When lettuce was planted into cowpea-incorporated treatment in 1999, conventional management had the highest cash return followed by integrated crop management. In 2000, organically-grown lettuce after cowpea incorporated had the highest net return followed by integrated crop management grown under cowpea incorporated treatments. In 1999 and 2000, integrated cantaloupe following cowpea-incorporated treatment had the highest yield and cash-return. A 20% price premium for organic produce increased the net returns for the organic-grown lettuce and cantaloupe. Organic lettuce following cowpea-incorporated treatments produced a high net of $2,516/ha in 1999 and $5,971/ha in 2000. The net returns due to 20% organic premium price varied between 1999 and 2000 in cantaloupe production. They were highest for organic cantaloupe after bareground with a net return of $4,395 in 1999 and $3,148 in 2000 for organic cantaloupe after sudangrass.

SUMMARYA study was conducted in Suba area, central highlands of Ethiopia, to assess the net return, land and labour productivity, and the return to scale of cereal farming practice. Seventy-five farmers belonging to three local wealth classes (poor, medium and rich) were randomly selected and interviewed about inputs and outputs related to cereal farming for the production year 2007/2008. Farm soil properties were investigated to check the variability in soil quality among the wealth classes. Benefit:cost ratio (BCR), net returns and annual profit were used to indicate the worthiness of the cereal farming activity. The return to scale was estimated by using the Cobb–Douglas production function. The results show that cereal farming is a rewarding practice, with the rich households gaining more profit than the poor. Farm size was the most important variable that affects the net return. There is an increasing return to scale. However, it is unlikely that farmers will have more land than they own at present because of the land shortage problem in the country caused by the increasing human population. Thus, attention should be given to minimizing the costs of production through proper regulation of domestic fertilizer costs and increasing labour productivity especially for the poor and medium households. The use of manure and compost as an additional fertilizer should also be promoted.

Abstract The objective of this study was to determine the best nutritional strategy for weaned calves at dry-to-rainy transition and rainy season and their effects on the growing phase. One hundred sixteen Nellore weaned males (initial BW of 173±23 kg; 10 months) were used in a randomized complete block design (blocked by BW) in a 2×2 factorial arrangement of treatments (divided in 12 lots with 9 or 10 animals/lot). Factor 1 was the strategy in the dry-to-rainy season transition (period I; pasture vs. drylot) and factor 2 was the strategy for the rainy season [period II; mineral salt ad libitum (MS) vs. supplement 3 g/kg BW]; consisting of four treatments: pasture in period I and MS in period II; pasture in period I and protein-energy supplement in period II (PEII); drylot in period I and mineral salt in period II; drylot in period I and PEII. At period I, all animals received a protein-energy supplementation (5 g/kg BW). The experiment lasted 244 days. Data were analyzed using the PROC MIXED of SAS. In period I, animals from drylot had highest final BW and ADG (P < 0.01; Table 1). There was no interaction among factors (P ≥ 0.772) in period II. In period II, ADG and carcass gain were highest from pasture animals (P < 0.01). Final BW and HCW were similar (P >0.788) at the end of period II, showing that animals recovery BW. Among strategies at rainy season, animals fed PEII had greater final BW and ADG (P < 0.01). Overall growing phase, HCW and carcass gain were greater for animals fed PEII (P < 0.01). Regardless of the strategy used in the dry-to-rainy season transition, animals were able to equalize final BW at the end of growing phase. In addition, protein-energy supplement at rainy season improves animal performance at the end of growing phase.

AbstractWeed management is one of the primary challenges for producers transitioning from conventional to organic agriculture. Tillage and the use of cover crops are two weed control tactics available to farmers transitioning to organic management, but little is known about their interactive effects on soil quality during the transition period. We investigated the response of soils to tillage and initial cover crop during the 3-year transition to organic in a cover crop–soybean (Glycine max)–maize (Zea mays) rotation in the Mid-Atlantic region of the USA. The tillage treatment contrasted full, inversion tillage with moldboard plowing (FT) versus reduced tillage with chisel plowing (RT). The cover crop treatment contrasted annual versus mostly perennial species during the first year of the rotation. The experiment was initiated twice (Start 1 and Start 2), in consecutive years in adjacent fields. By the end of the experiment, labile carbon, electrical conductivity, pH and soil moisture were all greater under RT than under FT in both starts. Soil organic matter and several other soil attributes were greater under RT than under FT in Start 1, but not in Start 2, perhaps owing to differences between starts in initial field conditions and realized weather. Soil attributes did not differ between the two cover crop treatments. Combining our soils results with agronomic and economic analyses on these plots suggests that using RT during the organic transition can increase soil quality without compromising yield and profitability.

Abstract Background and Aims Fatigue is a symptom with a high prevalence in patients on hemodialysis therapy due to uremic toxins, anemia, associated comorbidity, and hemodialysis treatment per se. Our objective is to evaluate the prevalence of fatigue reported by patients and their association with the nutritional status. Method This was a prospective observational, multicenter cohort study. Prevalent patients on HD therapy for at least 90 days, older than 18, at the Baxter Renal Care Services were included between September 1, 2017, to November 30, 2017 with one-year follow-up. Socio-demographic and clinical characteristics of all patients were summarized descriptively, the nutritional status was evaluated by protein Energy waste (PEW). Patient reported fatigue was measured with high flux membrane and medium cut-off membrane (Theranova). A generalized linear binomial multivariable model was conducted to assess the effect of PEW on fatigue symptom controlling for some confounding variables. Results We found that the fatigue reported by the patients has a prevalence of 55% [95% CI: 52.2 to 57.7] in our population, there are no statistical differences due to the use of different types of membranes p= 0.911, and neither did we find that the nutritional status is an independent factor that explains this symptom. If we find that women and diabetics have a higher risk of fatigue; RR=1.17 [95% CI: 1.06 to 1.29] and RR= 1.19 [95% CI: 1.00 to 1.42] respectively. Conclusion The fatigue is a prevalent symptom in the chronic hemodialysis population; being a woman and the diagnosis of diabetes are risk factors associated with this outcome. PEW and the type of dialysis membrane used were not associated with this symptom. Studies evaluating the recovery time from post-dialysis symptoms and its relationship with the type of membrane are necessary.

Weed control, yield, quality, and net return in reduced-cost and standard weed control systems were studied in “Sunbelt runner’ peanuts (Arachis hypogaeaL.) planted in a twin-row pattern in 1982 to 85 at Tifton, GA, and 1982 to 84 at Headland, AL. Reduced herbicide rates and/or less expensive herbicides were used to decrease weed control costs. In years and locations where weed populations were low there were no differences in weed control, crop yield, or quality. The lowest cost treatment, which included three applications of paraquat (1,1′-dimethyl-4,4′-bipyridinium ion), caused reduced weed control at both locations in 1982 and reduced yield in 1982 and 1984. None of the systems consistently resulted in the highest weed control, crop yield, or quality. A system including reduced rates of preplant-incorporated herbicides followed by two applications of paraquat performed as well as the standard system but cost about 40% less. Due to low cost and generally high yields this system resulted in consistently high net returns. Results indicate that the potential exists for reducing herbicide inputs without sacrificing yield or quality.

Abstract Background Lyme arthritis commonly presents as an acute inflammatory monoarticular arthritis, frequently challenging to distinguish from septic arthritis. While management for Lyme arthritis focuses on antibiotic therapy, septic arthritis requires operative debridement plus antibiotic therapy. Delay in Lyme serology results may complicate decisions on surgical intervention in Lyme endemic areas. During the transition period of western Pennsylvania to a Lyme endemic region many children ultimately diagnosed with Lyme arthritis were managed by operative intervention due to diagnostic ambiguity. The impact of an operative intervention on outcomes of pediatric Lyme arthritis is unknown. Methods We conducted a retrospective chart review from 2008 to 2018 of patients admitted to UPMC Children’s Hospital of Pittsburgh and diagnosed with Lyme arthritis. We recorded the clinical presentation, laboratory data, details of hospitalization and follow-up, costs and outcome after therapy to compare the impact of antibiotic therapy alone (non-operative group) vs. antibiotics plus operative debridement (operative group). Results We identified 164 patients admitted for management of arthritis with the eventual diagnosis of Lyme arthritis. Fifty-two patients underwent operative debridement in addition to antibiotic therapy. Operative debridement plus antibiotics was associated with increased duration of admission, increased the cost of hospitalization, and increased PICC line placement compared with antibiotics alone. In patients for whom follow-up information was available, resolution of symptoms was documented in 62 of 66 patients in the non-operative group and 46 of 47 patients in the operative group with a median duration to symptom resolution of 17 and 23 days,, respectively. Conclusion Operative debridement for pediatric patients with Lyme arthritis was associated with increased cost and duration of hospitalization, and a greater number of procedures, while being similarly efficacious to non-operative management with antibiotic therapy alone.

The study was undertaken to find out the export potentialities of selected vegetables and import substitution of selected spices in Bangladesh. Seven hundred twenty vegetables and 320 spices growers, 25 suppliers, and 25 exporters were randomly selected for the study.Net margin analysis was done on both variable and total cost basis. Domestic resource cost (DRC) analysis was also done for estimating comparative advantage of the selected vegetables and spices. The study revealed that net returns were positive for all vegetables and spices producers. However, the highest net return was estimated for brinjal producers (Tk. 273799/ha) followed by bittergourd producers (Tk152145/ha). In the case of spices, the highest net return was received by ginger producers (Tk. 231399/ha) followed by onion producers (Tk. 122308/ha).Comparatively lower net returns were found for okra (Tk51830/ha) and garlic producers (Tk 99352/ha). Vegetables exporters received the highest net margin (Tk32852/ ton) from UK market which was higher than the Middle East market (Tk22869/ton).The highest benefit cost ratio (BCR) was calculated for brinjal (1.9) followed by ash gourd (1.8). For spices, BCR were 2.1and 1.8 for ginger and garlic respectively. Bangladesh had comparative advantage for producing all selected vegetables as the estimates of domestic resource cost (DRC) were less than one. The value of DRC for all selected spices were less than unity implied that the production of these spices would be highly efficient for import substitution. Therefore, the study have been undertaken to find out this issues.Bangladesh J. Agril. Res. 42(2): 321-341, June 2017
