Abstract/ Executive Summary:

In this experiment, wastelage was prepared by ensiling Oat forage (Avena sativa) with fresh caged layer excreta (CLE) at varying proportions to investigate the feeding values of wastelage for cattle and protect environment from poultry droppings. Oat forage was mixed with 0, 20, 40 and 60% CLE and 5% molasses in each treatment on dry matter (DM) basis and ensiled in air tight plastic container under room temperature. After 56 days, ensiled mixtures were opened. All the wastelages had desirable aroma, yellowish green color, soft texture and were mould free. The pH, DM, crude protein (CP), crude fiber (CF), ether extra ct (EE), ash, nitrogen free extract (NFE), in vitro organic matter digestibility and metabolizable energy were significantly influenced by levels of CLE. The percentages of DM, CP and Ash (37.34, 18.95 and 14.45, respectively) were highest in wastelage with 60% CLE (p<0.05) followed by 40 and 20% CLE. The pH, CF and NFE were decreased linearly (p<0.05) from 4.5 to 3.90, 19.91 to 17.81% and 52.34 to 44.71%, respectively as the level of CLE increased from 0 to 60%. In all treatments, the EE content was not significantly influenced by the different level of CLE. The in vitro organic matter digestibility and metabolizable energy also increased significantly (p<0.05) with the increase of CLE and maximum value (65.5% and 9.10 MJ/kg DM, respectively) was obtained in wastelage with 40% CLE, which was statistically identical with 60% CLE. The results suggest that ensiling Oat forage with up to 60% CLE improve the feeding value of wastelage.

Start Date: 10-01-2012

End Date: 15-03-2012

Program Area: Animal Health and Management

Commodity: Cattle

Objectives:

1. To determine the optimum proportion of CLE that will improve the nutritive value and keeping quality of oat forage with an ultimate view to find out a convenient option of proper disposing of poultry droppings as well as to prepare a low cost feed for ruminants.

Methodology:

Caged layer excreta and oat forage were collected from Poultry Farm and field of Goat and Sheep Farm, respectively, Bangladesh Agricultural University, Mymensingh. For collection layer droppings, polyethylene sheet was placed under the cage of birds. During collection enough care was taken so that the droppings would be free from feather, sand or other materials. Molasses and air tight plastic containers were purchased from local market. Wastelage was prepared in the Goat and Sheep farm, Department of Animal Science, Bangladesh Agricultural University, Mymensingh during the period from 10th January to 15th March 2012. Oat fodder was harvested at the milk stage and 3 hours wilting to increase the dry matter content up to 35 percent. After wilting, fodders were chopped by 5 to 7 cm long. Then wastelage was prepared by mixing previously chopped fodder with fresh poultry droppings in varying ratios; 95: 0, 75: 20, 55: 40, 35: 60 and 5% molasses in each treatment. For proper mixing, first caged layer excreta and molasses were mixed then finally mixed with fodder. When fodders were properly mixed with caged layer excreta and molasses, these were placed into air-tight plastic containers which were previously marked according to the treatment. Finally plastic containers were kept in a room (25 to 28°C) for 56 days (8 weeks) for successful ensiling. pH of wastelage was determined by digital pH meter after putting 2g sample in 50 ml distill water. Dry matter was determined by drying the wastelage at 65°C for 48 h. Crude Protein (CP) was measured using Kjeldahl method (N × 6.25) while other proximate constituents, ether extract (EE), ash, crude fiber (CF) and nitrogen free extract (NFE). In vitro organic matter digestibility (IVOMD) and metabolizable energy (ME) content of wastelage were done. All data were analyzed using ‘MSTAT’ and ‘SPSS’ computer package program for a Completely Randomized Design, and differences among the treatment means were determined by Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

The results suggest that ensiling Oat forages with up to 60% caged layer excreta and 5% molasses significantly improves the nutritional values of wastelage and may be a feasible means of preserving and converting layer excreta, into a palatable and nutritious feed for cattle. In addition, this approach may also solve the disposal problem of poultry droppings in large poultry industries by utilizing it as an animal feed.
