Different fractions of maize plant and whole mixed fodder were analysed for their chemical composition and dry matter digestibility (DMD). Highest crude protein (CP) values were found in leaves as compared to the other portions. Younger plants contained more CP as compared to the matured ones. The crude fiber (CF) content of various fractions of the plant ranged between 19.12 to 35.60% with maximum values in the bottom portion of the stem. Matured plants contained more CF. The analysis of cell wall constituents indicated that the maximum values for neutral detergent fiber (NDF) were found in the bottom portion and in the whole mixed plant. The highest levels of acid detergent fiber (ADF) were observed in bottom fraction followed by whole mixed plant, whereas the other plant fractions did not show any differences. Variation in acid detergent lignin (ADL) values existed in different fractions of the plant and the lowest were in the top portion of the stem. Although there existed a variation in the mineral composition of different fractions of the plants, the results were non significant. Maximum DMD was found in leaves followed by the whole mixed plant, middle and bottom portion of the stem. The values of DMD were higher in younger plants as compared to the matured ones. It may be concluded that younger plants and the upper portion of the plants have a higher nutritive value as compared to the matured plants and lower portion of the plants.

This study was carried out to investigate the effects of three different locations of Sorghum ${\times}$ sorghum hybrid (SSH) silage on nutritive values and qualities of SSH square bale silage (SSBS) and gunny bag silage (GBS). SSH "SS405" was sown at early May, harvested at heading stage and ensiled. Samples of SSH silage used in this study were collected in three different locations (outer, middle and inner). The content of crude protein (CP) in GBS showed a slightly decreased trend, as compared to SSBS. However, the contents of neutral detergent fiber (NDF) was significantly different between SSBS and SBS (p<0.05). However, The contents of CP, NDF, acid detergent fiber (ADF) and total digestible nutrient (TDN), and in vitro dry matter digestibility (IVDMD) were not different between the parts of SSH silage. Nutritive values of SSBS and SBS were not influenced by inoculation of lactic bacteria. The content of lactic acid in SSBS was decreased as compared to SBS, but there was no significant difference between SSBS and SBS. The content of acetic acid in SSBS was significantly decreased (p<0.05), as compared to SBS. In addition, the contents of lactic acid, acetic acid and butyric acid were not different between the parts of SSH silage. Therefore we suggest that nutritive values and quality of SSBS and SBS were not influenced by parts of sampling collected from these silages.

This study was performed to investigate the nutritive values of white panicled rice (Oryza sativa L., WPR) silage manufactured with WPR grown in reclaimed paddy field of Bigumdo of Korea in 2011. The WPR used in this study were collected in 1,000 ha of reclaimed paddy field of Bigumdo and was harvested at dough stage and ensiled. The yield of whole crop rice (WCR) grown in region received the most severe damage (MSD) was lower as about 800 kg/ha as than that in region of normal growth (NG). The content of crude protein and total digestible nutrient in WCR of MSD slightly increased, as compared to that in WCR of NG, but the contents of acid detergent fiber and neutral detergent fiber significantly decreased (p<0.05). The pH in WCR silage of MSD and NG ranged from 4.5 to 5.0 and pH decreased by the inoculation of lactic bacteria (p<0.05). The content of lactic acid in WCR silage of MSD and NG increased by the inoculation of lactic bacteria (p<0.05), but the content of acetic acid and butyric acid decreased (p<0.05). Flieg's score in WCR silage of MSD and NG inoculated lactic bacteria increased from 2 to 3 grade, as comparing to non-inoculation of lactic bacteria. Therefore, this study suggests that WPR can be utilized as forage.

In order to provide basic data to predict changes of milk components in milk yield, this study was conducted to compare nutritive values of diets collected from organic dairy farms (ODF) and conventional dairy farms (CDF) of Chungnam and Jeonbuk in Korea. The contents of crude fat, crude fiver, neutral detergent fiber, and acid detergent fiber in diets of ODF were significantly (p<0.05) higher compared to those of CDF. The contents of crude protein and crude ash in ODF were also higher (p<0.05) than those of CDF. The contents of calcium, ferrum, and phosphorus in diets of ODF were similar to those of CDF. The contents of potassium, magnesium, and iodine in diets of ODF were higher (p<0.05) than those of CDF. The contents of total saturated and unsaturated fatty acids in diets of ODF were higher (p<0.05) compared to those of CDF. The contents of oleic acid, linoleic acid, and linolenic acid in diets of ODF were higher (p<0.05) compared to those of CDF. However, the contents of myristic acid, palmitic acid, and stearic acid in diets of ODF were lower (p<0.05) compared to those of CDF.

To provide the basic data on the utilization of chlorella as a method to improve the quality of forage, we examined the effect of the addition of lactic acid bacteria (LAB) and chlorella on the change of nutritive value, quality and microbes on Italian ryegrass and alfalfa mixture silage (IRG-Alfalfa silage). The nutritive values of IRG-Alfalfa silage were not significantly different in all treatments. The pH of IRG-Alfalfa silage decreased in both LAB and chlorella treatments. Further the content of lactic acid in the LAB treatment increased as compared to the control, and also significantly increased in the treatment of LAB with chlorella (p<0.05). In addition, the number of LAB increased in lactic acid bacteria treatment as compared to the control, and also increased in the treatment of LAB with chlorella (p<0.05). Therefore, we suggest that LAB and chlorella would improve the quality of IRG-Alfalfa silage.

This experiment was conducted to compare the fresh yield and dry matter yield, and nutritive values of whole crop barley treated with Urea (200 kg/ha, T2) and ammonium sulfate fertilizer as 200 kg/ha (T3), 300 kg/ha (T4) and 400 kg/ha (T5) at the Bae-Ho reclaimed tideland. Korea from 2003 to 2005. Salt contents of soil in the ammonium sulfate plots (T3, T4, T5) were lower than those of T2. The fresh yields of ammonium sulfate plots (T3, T4, T5) were higher than those of T2 as 62% (p>0.05), 41% (p>0.05) and 23% (p<0.05), respectively. The dry matter yield of T3, T4 and T5 (ammonium sulfate) was significantly (p<0.05) higher at 5,080 kg/ha, 4,667 ka/ha, 4,040 kg/ha, respectively. The total digestible nutrients (TDN) yield tends to have a similar result. Crude protein (CP) content was highest in T3 and CP trends to decrease as the level of ammonium sulfate was increased. Total digestible nutrient (TDN) were high in T3 and T4. The sodium content of T3 and T4 were lower than T2. Based on the study, it was more desirable to use ammonium sulfate (200 kg N/ha) rather than Urea as fertilizer on reclaimed land in terms of forage production and nutritive value.

The potential nutritive value was studied on leaves of seven fodder trees in Central Sudan during dry season at two distinct periods, the early dry and the late. The chemical composition, mineral concentration, in vitro organic matter digestibility (IVOMD), in situ OM or nitrogen degradability and estimated metabolizable energy showed a wide variation among fodder tree species and between different periods of the dry season. Crude protein (CP) ranged from 285 to 197 g/kg DM at early dry season, with a significant reduction in late dry season. Ziziphus spina-christi and Balanites aegyptiaca showed the least reduction in CP content. The NDF, ADF and lignin were about 200, 160 and 19 g/kg DM, respectively at the early period, and significantly increased at the late period of the dry season, except for lignin of Z. spina-christi. For mineral concentration, all fodder tree leaves were rich in calcium but poor in phosphorus. In situ OM degradability significantly decreased at the late period of dry season, but values remained as high as over 600 g/kg OM. At both periods, Z. spina-christi showed the highest value, while the lowest was recorded in Acacia seyal. The IVOMD showed a similar trend to those of in situ OM degradability, except for A. seyal. The nitrogen degradability was highest in B. aegyptiaca and lowest in Z. spina-christi at both periods. A significant and positive correlation had existed between CP and IVOMD or in situ OM degradability (r=0.68, p<0.05; r=0.77, p<0.05, respectively). Also, a significant but negative correlation was found between condensed tannins and nitrogen degradability (r=-0.87, p<0.01). Results demonstrated that Z. spina-christi potentially has a good nutritive value as dry season feed or supplement, while A. seyal tends to be less promising. A. nubica and B. aegyptiaca may be a useful source for degradable protein, even though it may have a limited supply of energy to animals. A. tortilis, A. mellifera and A. ehrenbergiana may have potential value for a supplementation of energy or protein, if they were harvested in the early dry season or in wet season as preserved feed. It is highly recommended to supplement with an appropriate amount of phosphorus when these fodder trees were used.

This experiment was conducted to determine the effects of cutting height on the yield and nutritive value of brittle culm rice. A brittle culm cultivar, KL501, was compared with a non-brittle culm rice, Seomjinbyeo. The cultivars were grown in paddy until flowering stage at which the first cutting was made followed by the second cutting on October 20. Cutting regime conducted were 0, 5, 10 and 20cm from the surface. Herbage yield, TDN and other nutritive values were measured. As the higher cutting height, crude protein, fat and NFE (nitrogen free extract) contents were increased and crude fiber and ash content were decreased at the first cutting, while those at second cutting were increased except NFE content. Fresh and dry matter yield at 10cm cutting height, Seomjinbyeo was 4.45 and 1.16t /ha, KL501 was 4.71 and 1.14t /ha, respectively. TDN content of first cutting was increased as the higher cutting height, but that of second cutting was decreased. TDN yields of Seomjinbyeo and KL501 at 10cm cutting height were highest by showing 0.63t /ha and 0.61t /ha, respectively.

To evaluate the nutritive values of outdoor mass cultivated Spirulina platensis both chemical analysis and bioassay were carried out using adult cockerels. Blue-green algae, Spirulina platensis contained about 71g /l00g DM of crude protein with balanced amino acid profiles although methionine is liable to he limiting to animals. Compared to fish meal, calcium content and calcium : phosphorus ratio of the Spirulina were not suitable in terms of animal requirements. Reasonable amount of y-linolenic acid(C18: 3 $\omega$6) in Spirulina platensis draws a clinical attention due to its historically recognized pharmacotheraputic functions. Metabolizable energy contents of Spirulina were 3.67 and 3.11 mcal /kg DM for TMEn and AMFn, respectively, which therefore, can he a reliable energy source for poultry. True amino acid availabilities of essential amino acids of Spirulina platensis were higher than 90% for poultry, which is better than comparative ingredient like fish meal. Overall data from both chemical analysis and bioassay demonstrated that the Spirulina platensis could he a favorable protein feedstuffs for poultry.
