Implementation of agricultural residues for oyster mushroom culture has been accepted world-wide. In this study, we used wheat straw, barley straw, maize stem residue, and lawn residue as substrates coupled with wheat bran, rice bran and soybean powder as complements for the growth of P. florida. Wheat and barley straws which contained a high fiber and C/N ratio had the best growth period, fruiting body weight, yield, and biological efficiency. Assessment of substrate and complement combinations indicated that the lowest growth period was obtained from barley straw enriched with rice bran (24.67 day). However the highest fruiting body number (36.33), fruiting body weight (31.17 g), yield (1039 g), and biological efficiency (207.8 %) belonged to wheat straw complemented by either wheat or rice bran. In conclusion, the highest fruiting body weight, yield, and biological efficiency was achieved by implementation of composts in which high fiber substrates and complements were combined.

Aims: We investigated most suitable substrate (wheat and rice straw) enriched with vermicompost and their different levels (10%, 25%, 50%, 75% and 100%) for enhancing production of milky mushroom.  Study Design: The experiment was designed by following single factor Randomized Complete Block Design (RCBD).  Place and Duration of Study: The experiment was conducted in a mushroom culture house to observe the growth and productivity of highly potential milky mushroom by using different vermicompost enriched substrate during March-October, 2017 Methodology: Based on the different treatment combinations the quantity of substrate and vermicompost on volume basis were used per packet with 5% spawn. Coco dust was used as casing material. After incubation, matured fruiting bodies were harvested and data were recorded on growth and yield parameters. Results: The addition of vermicompost with rice substrates improved the diameter of pelius 32-74%, thickness of pelius 26- 60%, diameter of stipe 24-55% and length of stipe 25 to 95% relative to the unsupplemented substrate. Similarly, vermicompost supplementation with wheat straw substrates increased the diameter of pelius 27-71%, thickness of pelius 11- 40%, diameter of stipes 21-56% and length of stipe 17- 72% relative to the unsupplemented substrate at any harvest. Supplementation of vermicompost reduced the duration for spawn run 11-55% in wheat straw and 11- 49%  in rice straw compared with non-supplemented one. Furthermore, pin head initiation became quicker 26- 66% in wheat straw and 15- 61% in rice straw. In addition, total number of fruiting body increased from 6- 82% in wheat straw supplemented with different doses of vermicompost, while rice straw increased total number of fruiting body ranged from 17- 39% compared to unsupplemented one. The addition of 10%, 25%, 50% and 75% levels of vermicompost with wheat straw increased the fresh yield of C. indica by 23%, 54%, 121% and 73%, respectively compared to wheat straw alone; however, similar levels of vermicompost with rice straw increased the fresh yield of C. indica by 31% , 63%, 112% and 87%, respectively compared to rice straw alone. The biological efficiency of C. indica also did exhibit significant differences ranged between 65-160% among different levels of vermicompost supplementation with rice and wheat straw substrates. Conclusion: The result revealed that increasing the vermicompost level lead to a less biological efficiency and yield, but it remains higher than the control (straw alone). It is additionally conceivable that the application of vermicompost to substrates with lower levels would provide an even better yield, without adversely affecting the bioefficiency of the harvested mushrooms. These judges, however, need more work to validate reliability.

High Fiber Diet

Experiments were conducted to determine the effect of feeding a high (19.6%) or low (7.7%) fiber diet to meat- and egg-type chickens during the last 6 wk of their growing period followed by a high (12.4%) or low (6.2%) fiber diet during the breeding period. The addition of finely ground wheat straw at 40% of the ration during 15–21 wk of age resulted in a significant reduction in feed consumed, exclusive of the added fiber, per hen–day in both strains and a reduction in body weight gain per bird, but it had no effect on feed conversion efficiency. The addition of fiber also resulted in a significant increase in weight (and size) of various components of the digestive system in both strains when this was prorated to body weight. The carryover effects of feeding high fiber during the growing period were manifested by increased rate of lay and body weight gain in both strains, irrespective of the breeding period diet. However, pre-treatment on high fiber growing diet resulted in increased feed efficiency of both strains of hens fed a low fiber breeding diet, but not of the hens fed a high fiber breeding diet. The high fiber rations (20% wheat straw) fed during the breeding period depressed rate of lay and feed efficiency but did not affect the weight, quality, fertility or hatchability of the eggs. Mortality during the growing and breeding periods was not affected by the high fiber diet. Apparently chickens are capable of a high degree of anatomical and physiological adaptation to compensate for variation in nutrient concentration of their diet. Such adaptation during the growing period showed some beneficial effects on breeding period performance in meat- and egg-type chickens.

We investigated the effect of chemically disinfected wheat straw on the growth and yield of oyster mushroom (Pleurotus ostreatus). Various levels of treatments combined with different time (12, 18 and 24 hours) and dose of Formalin (250, 500 and 750ppm) and Bavistin (75ppm) were used, and the results were compared with the control. Compared to the control, almost all the treatments showed increased values, and among them significantly higher mycelium running rate, the lowest time from stimulation to primordial initiation and to harvest, number of primordial per packet, number of fruiting body per packet were found in treatment consists of 750ppm of Formalin with 75ppm of Bavistin for 18 hours. Length and diameter of the stipe, diameter and thickness of pileus, biological yield, economic yield, dry yield and biological efficiency were also significantly increased in this treatment. Wheat straw treated with 500ppm of Formalin with 75ppm of Bavistin for 18 hours performed best in terms of per cent protein and nitrogen content. However, weight of individual fruiting body was significantly higher when treated with 250ppm Formalin with 75ppm of Bavistin for 24 hours.As the sterilization of wheat straw using 750ppm of formalin with 75ppm of Bavistin for 18 hours could control pathogens and gave increased yield, this treatment might be useful as an economically effective treatment for the highest yield of oyster mushroom.

Stage 1

This study was conducted to determine the effects of low-protein diet prepared with different levels of defatted rice bran (DFRB) and weight stages on growth performance and nutrient digestibility of growing–finishing pigs. The animal experiment included three stages. A total of 240 growing pigs with an initial body weight of 28.06 ± 8.56 kg for stage 1 were allocated to five diets including one control group and four DFRB diets supplemented with 2.5%, 5%, 7.5% and 10% DFRB, respectively. The 192 crossbred pigs with initial body weights of 55.03 ± 7.31 kg and 74.55 ± 9.10 kg were selected for stage 2 and stage 3, respectively. Pigs were allocated to four diets including one control group and three DFRB diets supplemented with 10%, 15% and 20% DFRB, respectively. The results showed that with the increase in DFEB intake, the gain: feed was linearly increased (p < 0.05), and the average daily feed intake tended to linearly decrease (p = 0.06) in stage 1. Except for the apparent total tract digestibility (ATTD) of acid detergent fiber (ADF) in stage 3, levels of DFRB had significant effects on the ATTD of gross energy (GE), dry matter (DM), ash, neutral detergent fiber (NDF) and ADF in three weight stages. In stage 1, with the increase in levels of DFRB, the ATTD of NDF and hemicellulose were firstly increased and then decreased (p < 0.01). In stage 2, with the increasing levels of DFRB, the ATTD of DM, ash and cellulose were firstly increased and then decreased (p < 0.01). In stage 3, the ATTD of GE, DM, ash, NDF and hemicellulose decreased linearly with the increase in levels of DFRB (p < 0.01). Collectively, DFRB could be used as a replacement for corns and soybean meal, and weight stage is important to consider when adjusting the additive proportion.

Abstract Female hair sheep, 27 Dorper (DOR), 41 Katahdin (KAT), and 39 St. Croix (STC), were used to determine influences of nutritional planes before and after breeding on performance. There were 35 multiparous and 72 primiparous sheep, the latter 2.8±0.20 yr of age. Wheat straw [4% crude protein; dry matter (DM) basis] was consumed ad libitum and supplemented with approximately 0.25% initial body weight (BW) of soybean meal (SBM; Low) or a 1:3 mixture of SBM and rolled corn at 1% BW (High; DM). The supplementation period was 162 d, and with breeding of animals in 2 groups sequentially the pre-breeding period was 84 and 97 d and that after breeding began was 78 and 65 d. Wheat straw DM intake (1.75, 1.30, 1.57, 1.15, 1.80, and 1.38% BW; SEM=0.112), average daily gain (-46, 42, -44, 70, -47, and 51 g; SEM=7.3), and change in body condition score (-0.61, 0.36, -0.53, 0.27, -0.39, and -0.18 for DOR-Low, DOR-High, KAT-Low, KAT-High, STC-Low, and STC-High, respectively; SEM=0.058) were influenced (P &lt; 0.05) by supplement treatment. Birth rate (66.7, 93.5, 84.6, 95.5, 82.8, and 100.0; SEM=9.83) and individual lamb birth weight (4.50, 4.61, 4.28, 3.98, 3.73, and 3.88 kg; SEM=0.201) were not affected by supplement treatment (P = 0.063 and 0.787, respectively), although litter size (0.92, 1.21, 1.17, 1.86, 1.12, and 1.82; SEM=0.221) and total litter birth weight (5.84, 5.74, 5.92, 7.52, 5.04, and 6.78 kg for DOR-Low, DOR-High, KAT-Low, KAT-High, STC-Low, and STC-High, respectively; SEM=0.529) were greater (P &lt; 0.05) for High than for Low. In conclusion, although there was some compensation in wheat straw intake for the different levels of supplementation, SBM given alone rather than with cereal grain adversely affected body weight and condition and reproductive performance, the latter primarily through litter size but also via a trend for an effect on birth rate.

AbstractAgricultural waste disposal is one of the main concerns in today's world that can cause environmental pollution. Utilisation of agro-waste materials to grow mushrooms is an eco-friendly method to reduce pollution. Therefore, various agricultural waste materials, such as wheat straw, rice straw and cotton waste, were utilised for the production of milky mushroom. Among the substrates used in this study wheat straw showed superior substrate for the production of milky mushroom. The agronomic traits studied such as total yield, number of fruiting bodies, the maximum diameter of pileus and stalk length, biological efficiency, protein contents, phosphorous and potassium contents were observed on wheat straw substrate. Peat moss, loam soil and spent mushroom substrate were used as casing materials. Among the casing materials used, the highest yield and biological efficiency were observed on peat moss. The results also indicated that the addition of supplements with the substrate improved yield and yield contributing characteristics. Among the tested supplements (wheat bran and rice bran), wheat bran was the best supplement for wheat straw substrate to cultivate milky white mushroom.

This research aims to analyze the physical and sensory characteristics of cookies’ formulations using mocaf-oats-rice bran’s flour mixture. Five formulations used in this research consist of mocaf-oats-rice bran’s flour mixture namely F1 (100%-0%-0%), F2 (70%-15%-15%), F3 (50%-25%-25%), F4 (30%-35%-35%), and F5 (0%-50%-50%). The result showed that all cookies formulation included in the category of “high fiber” except for cookies Formulation 4. The highest value of hardness was cookies Formulation 1 and significantly different from the other formulations. Decreasing mocaf flour composition in the mixture and increasing additional oats and rice bran composition have a significant correlation on cookies’ hardness. Based on sensory evaluation using rating preference, it was found that the highest rating for color, texture, and overall parameters obtained by cookies Formulation 4, while the highest rating for taste parameter obtained by cookies Formulation 5. Cookies’ formulation that recommended to use as utilization of mocaf flour was Formulation 4 because it had the highest rating for overall parameter, as well as highest rating for color and texture.

Olive Mill

Two-phase olive mill waste (TPOMW, “alperujo”) is a highly biotoxic sludge-like effluent of the olive-oil milling process with a huge seasonal production. One of the treatment approaches that has so far received little attention is the use of TPOMW as substrate for the cultivation of edible mushrooms. Fifteen fungal strains belonging to five species (Basidiomycota), that is,Agrocybe cylindracea,Pleurotus cystidiosus,P. eryngii,P. ostreatus, andP. pulmonarius, were evaluated for their efficacy to colonize media composed of TPOMW, which was used either raw or composted in mixtures with wheat straw in various ratios. Qualified strains exhibited high values of biological efficiency (e.g., 120–135% forPleurotusspp. and 125% forA. cylindracea) and productivity in subsequent cultivation experiments on substrates supplemented with 20–40% composted TPOMW or 20% raw TPOMW. Only when supplementation exceeded 60% for raw TPOMW, a negative impact was noted on mushroom yields which could be attributed to the effluent's toxicity (otherwise alleviated in the respective composted TPOMW medium). Earliness and mushroom size as well as quality parameters such as total phenolic content and antioxidant activity did not demonstrate significant differences versus the control wheat-straw substrate. The substrates hemicellulose content was negatively correlated with mycelium growth rates and yields and positively with earliness; in addition, cellulose: lignin ratio presented a positive correlation with mycelium growth and mushroom weight forA. cylindraceaand with earliness for all species examined. TPOMW-based media revealed a great potential for the substitution of traditional cultivation substrates by valorizing environmentally hazardous agricultural waste.

Three experiments were carried out with replacement ewe lambs to determine the influence of feeding rations containing three levels of protein, each at two levels of digestible energy. The three levels of protein were approximately 8, 9.5, and 11 per cent in the first two experiments, and 6, 9, and 12 per cent in the third experiment.Increasing the amount of protein in the ration resulted in an increase (p <.05) in the apparent digestibility of the protein, but no change in the percentage of protein retained or in the digestibility of the dry matter and gross energy. Increasing the digestible energy content of the ration by substituting corn starch for wheat straw or oat hulls reduced (p <.05) the digestibility and retention of protein in Experiments 2 and 3, but had no effect in Experiment 1.Body weight gains and wool growth of lambs fed rations containing wheat straw or oat hulls did not increase to so great an extent as those fed corn starch. This would indicate that energy was a limiting factor for maximum production in the lower digestible energy rations. In general, weight gains and wool production increased (p <.05) when the daily intake of D.C.P. was increased from approximately 0.10 to 0.13 pounds. Increasing the D.C.P. from 0.13 to 0.16 pounds (0.19 in Experiment 3) caused no further increase in body gains but increased (p <.05) wool production.On the basis of these results, the average D.C.P. requirements of a ewe lamb weighing 85 pounds and consuming 1.3 pounds T.D.N. was 0.13 pounds (0.16 pounds when wool production was considered).
