Preparation of wastelage with poultry droppings and rice straw (Oryza sativa L.) as a cattle feed

Abstract

The use of poultry droppings as a feed ingredient may not only reduce waste and environmental pollution but also provide inexpensive feed components for ruminants. An experiment was conducted to prepare wastelage in the field laboratory of Animal Science Department, Bangladesh Agricultural University, Mymensingh. Rice straw (Oryza sativa L.) was mixed with 0%, 10%, 20% and 30% caged layer excreta (CLE) and 5% molasses in each treatment on dry matter (DM) basis and ensiled in air tight container under room temperature. After 60 days, ensiled mixture was opened. All the wastelage had desirable smell, light brownish color, soft texture and no fungal growth was found. Results revealed that PH, DM, crude protein (CP), crude fiber (CF), ash, in vitro organic matter digestibility and metabolizable energy were significantly (p<0.05) influenced by different levels of CLE. The highest CP (5.97g/100g DM) was observed in wastelage with 30% CLE (p<0.05) followed by 20% and 10% CLE. The PH level, DM, Ash and CF contents were decreased linearly (p<0.05) from 4.8 to 4.11, 78.00 to 55.63, 25.08 to 17.70 and 22.57 to 14.95%, respectively as the level of CLE increased from 0 to 30%. In all treatments, EE content was not significantly influenced by the different level of CLE. The in vitro organic matter digestibility (IVOMD) and metabolizable energy (ME) also increased significantly (p<0.05) with the increased level of CLE and maximum value (57.51%, and 8.12 MJ/Kg DM, respectively) was obtained in wastelage with 10% CLE, which is statistically identical with 20% CLE. Therefore, it could be speculated that ensiling rice straw with up to 20% CLE improved the feeding value of wastelage.Asian J. Med. Biol. Res. September 2018, 4(3): 251-258

Culture and production of Lucilia sericata Meigen (1826) larvae for rearing stinging catfish Heteropneustes fossilis (Bloch, 1794) using poultry waste

“…These organic and inorganic nutrients in waste contribute to the growth of microalgae and the biosynthesis of significant amounts of protein, lipids, carbohydrates, and ash Melo et al, 2018). Chicken manure can encourage the growth and synthesis of additional protein, lipids, and carbohydrates by bacteria, fungus, microalgae, and fly larvae (Hasnol et al, 2020;Cammack and Tomberlin, 2017;Islam et al, 2018). Fly larvae, especially flies (Lucilia sericata), can use these nutrients as a cheap alternative (Zhang et al, 2021;Mazza et al, 2020;Parry et al, 2020;Firoozfar et al, 2011).…”

Utilization of poultry droppings in terms of non-waste technology

“…In [7], the analysis of manure processing technology is carried out, which allows producing several types of the final product, unifying production, reducing economic costs and optimizing labor costs. The study [8] showed that poultry waste can be used as a suitable renewable medium for the growth of Chlorella sp. Consequently, the author analyzed the use of poultry waste, but unfortunately this technology and its advantages are not disclosed.…”

Preparation of wastelage using poultry droppings with maize stover and its nutrient content as ruminant feed

“…When properly ensiled, wastelage is free of salmonella type microorganisms and parasitic nematodes, free of noxious odors, palatable to livestock, and economically competitive as an animal feed. (Mavimbela, 2000;Islam et al, 2018).…”
