Study on Nutritive Values of Whole Crop Barley Varieties Grown in a Paddy Field

Abstract

This study was carried out to investigate the growth characteristics, yield, chemical compositions and nutritive yield of whole crop barley varieties harvested in a paddy field. The experimental design was arranged in a randomized block design with three replications. The treatments consisted of five whole crop barley varieties (Yuyeon, Youngyang, Wooho, Dami, Soman). The planting date was on 21 October 2009 and the samples were harvested on 21 May 2010. Dry matter yield was higher in Youngyang and Dami than other varieties (p<0.05). Crude protein, crude fat, crude ash, ADF and TDN were not significantly different. Crude fiber was the highest at Dami (31.4%), and Youngyang (31.4%) exhibited the lowest crude fiber compared to other varieties (p<0.05). NDF was higher in the order of Wooho > Dami > Soman > Yuyeon > Youngyang (p<0.05). Total mineral content was higher in the order of Youngyang > Wooho > Dami > Soman > Yuyeon (p<0.05). The contents of both essential and non-essential amino acids were not different among whole crop barley varieties. Yields of crude protein was the highest in Wooho (p<0.05), and yields of mineral, amino acid, free sugar and TDN were the highest in Youngyang. Based on the results from this study, it can be suggested that Youngyang and Wooho showed to have higher productivity and high nutritive values compared to other varieties.

Effects of seeding dates on dry matter yield and feed values of whole-crop barley cultivated in a paddy field

“…Total mineral content was highest for seeding date T1 ( p < 0.05) at 31,308 mg/kg and lowest for T5 ( p < 0.05) at 15,978 mg/kg. These values are lower than those reported by Kim and Lee [1], who determined mineral contents of between 39,027 and 51,914 mg/kg for whole-crop barley varieties. Generally, it is known that mineral content is affected by a range of conditions, including those of weather, soil, and fertilization [26–28].…”

“…The non-essential amino acid content trend was T5 > T4 > T3 > T2 > T1 ( p < 0.05). The range of total amino acids by seeding date was from 7,066 to 7,747 mg/100 g. These values are higher than those (5,971–6,499 mg/100 g) reported by Kim and Lee [1]. The total amino acid content was highest in T5 and lowest in T1.…”

“…However, in Korea, because there is a limited production capacity for forage and grains, dependency on foreign imports has been rising. The price of imported hay and grain can fluc-tuate markedly, depending on international supply capacity, and under such circumstances it is difficult for farmers to continue rearing livestock [1]. Therefore, to supply home-produced meat to customers in Korea, it is imperative to expand forage production capability to meet the demand for ruminant production.…”

“…However there was no differences in total free sugar content among T1, T2, T3 and T4. Total free sugar content is lower than that of silage corn, as reported by Lee (2012), and shows a similar content as barley, reported by Lee and Kim (2013). Generally, forage crop's free sugar content is a very important ingredient because it affects the silage fermentation (Lee and Lee, 2010;Lee 2012).…”
