Preparation of Wastelage with Poultry Droppings and Oat Forage (Avena sativa) as a Feed for Cattle

Abstract

Abstract: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.

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

“…CP content increased with the ensiling time increase when maize stover ensiled with nitrogen source CLE (Kayongo et al, 1986). Khatun et al (2013) and Al-Rokayan et al (1988) agree with the present findings. Both of them, reported that the crude protein of forages ensiled with broiler litter increased with increased proportion of poultry litter.…”

“…The Ash content was decreased significantly (p<0.05) with the increase of CLE. This result is not supported by Al-Rokayan et al (1988), Flachowsky and Hennig (1990) and Khatun et al (2013) who observed a linear increase in ash with increased proportion of broiler litter. It may be happened due to processing method or other environmental factors.…”

“…Among all the treatments, T 1 (10% CLE) and T 2 (20% CLE) had good smell but T 3 (30% CLE) had pungent smell which was not acceptable by cattle. A pleasing aroma, good color and soft texture was obtained when poultry droppings were ensiled with maize forage (Harmon et al, 1975), citrus pulp or weeds (Hadjipanayiotou, 1982) and Oat forages (Khatun et al, 2013). The P H of wastelage is shown in Figure 1.…”

“…Snijders and Wouters, (2004) reported DM loss of 81% in ensiled maize stover. DM content was reduced from 28.0 to 26.4%, with increasing the ensiling time from 2 to 4 months (Man and Wiktorsson, 2003. But, Khatun et al (2013 reported that the increasing level of DM in ensiled Oat forage with increased level of caged layer excreta.…”

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

“…Ensiling of chopping maize stover along with poultry droppings and molasses may produce a good quality wastelage for feeding cattle having desire palatability, nutrient content and digestibility. (Harmon et al, 1975;Khatun et al, 2013). Panna et al (2019) found that 30% and 45% poultry dropings are acceptable for preparing wastelage.…”
