호밀은 월동작물 중에서 추위에 가장 강하고, 낮은 온도에서 빨리 성장하는 특성을 가지고 있어 다른 작물보다 한 달 빠른 4월 중 하순에 수확이 가능하다. 이런 장점으로 호밀을 월동기온이 낮아 겨울작물 재배가 어렵거나 벼를 빨리 이앙하는 지역에서 풋베기용이나 사일리지용 조사료로 많이 재배되고 있다. 그러나 호밀은 도복에 약하고, 이삭이 나온 이후 사료의 질이 떨어지기 때문에 수량이 많고 사료가치가 좋은 호밀 조사료를 생산하려면 세심한 관리가 필요하다.

This study was conducted to investigate the effect of addition of lactic acid bacteria inoculants on quality of rye silage harvested at early heading stage. The nutritive values in lactic acid bacteria (LAB) inoculated group showed similar results to control. The pH of rye silage in LAB inoculation significantly decreased as compared to control (p<0.05). In addition, the content of lactic acid in LAB inoculation significantly increased (p<0.05), but the content of acetic acid in LAB treatments decreased. In addition, lactic acid bacterial counts in LAB inoculation significantly increased as compared to control (p<0.05). Therefore, we suggest that rye silage could be improved by LAB inoculation.

This study was conducted to investigate the effect of novel Lactobacillus plantarum KCC-10 and KCC-19 on the quality and fermentation characterization of rye silages. The study was conducted at the National Institute of Animal Science, Cheonan province in Korea and consisted of three treatments: control without lactic acid bacteria, treatment with L. plantarum KCC-10 and treatment with L. plantarum KCC-19. The amounts of acid detergent fiber and neutral detergent fiber as well as the in vitro dry matter digestibility in KCC-10 and KCC-19 were similar to the control. The pH of rye silage in L. plantarum KCC-10 and KCC-19 treatments decreased compared to the control (p<0.05). The amount of lactic acid in L. plantarum KCC-10 and KCC-19 treatments increased (p<0.05), but the amounts of acetic acid and butyric acid in KCC-10 and KCC-19 treatments decreased (p<0.05). In addition, the number of lactic acid bacteria in L. plantarum KCC-10 and KCC-19 treatments increased compared to the control (p<0.05). Therefore, we suggest that rye silage was improved by the addition of L. plantarum KCC-10 and KCC-19.

The present study was conducted with four ruminally fistulated cattle to examine the fermentation characteristics and effective degradability (ED) in the rumen, and whole tract digestibility and TDN values of various silages (whole crop rye, RS; whole crop barley, BS; Italian ryegrass, IRGS and sudangrass, SGS) which were produced in Korea. The pH of rumen fluid were not greatly affected by silage at most times after feeding but SGS decreased (p<0.049) the ruminal ammonia-N concentration as 7.28 mg/100 ml at 3h after feeding compared to other silages. An acetate proportion from SGS feeding was higher at 1h (p<0.018), 3h (p<0.004) and 6h (p<0.019) after feeding than those from other silages. The propionate ($C_2$) proportion, however, was greater (p<0.001~p<0.042) for the RS and BS than the corresponding values of other silages up to 6h after feeding while the lowest $C_2$ proportion was observed from SGS. The butyrate proportion was lowest (p<0.007~p<0.027) in the cattle fed BS at 1~6h after feeding among silages. An ED of dry matter (DM) in the rumen was highest (P<0.048) for RS as 59.64%, and was reduced in the order of BS (56.12%), IRGS (55.64%) and SGS (54.02%). Similar tendency was observed in the EDs of crude protein (p<0.014) and organic matter (OM, p<0.039). The whole tract digestibility of DM (p<0.032), neutral detergent fiber (NDF, p<0.034) and OM (p<0.041) of SGS was greatly reduced. The TDN value based on whole tract digestibility of silages was highest for RS as 61.1%, and TDN values of BS, IRGS and SGS were 57.1%, 57.9% and 50.7%, respectively. Based on the results obtained from the present study, components in various whole crop silages produced in Korea might affect the ruminal VFA proportion, and especially, NDF content could greatly influence on the TDN value of silage calculated based on the NDF content.

The present study was conducted to examine the fermentation characteristics and effective degradability (ED) in the rumen, and whole tract digestibility of whole crop silage based TMR in comparison with conventional separate feeding of concentrate and roughage. Three ruminally fistulated non-lactating Holstein cattle were used in a 3 $\times$ 3 Latin square design. The cattle were fed 8kg of whole crop barley silage based TMR (BS-TMR) or 8kg (DM basis) of whole crop rye silage based TMR (RS-TMR) twice (08:00 and 18:00) daily in an equal amount. The cattle were also fed concentrate (5.6kg) and rice straw (1.4kg) seperately (DM basis, Control) twice daily in an equal amount. The both silages were included in TMR at 20% level (as fed basis). pH in the rumen fluid was not influenced by the diets but was slightly higher from TMR than from control. No difference was found in ammonia-N concentration between diets. Total VFA concentration was relatively increased in the cattle fed RS-TMR to the other diets up to 6h post feeding. The proportion of acetate was increased in the TMR feeding at right before feeding (0 h, p<0.005) and 9 h (p<0.048) post feeding compared with control. Propionate proportion was increased (p<0.046) in both TMRs while butyrate proportion was increased (p<0.029) at 1h post feeding compared to other diets. Effective degradability (ED) of DM and CP of RS-TMR was relatively increased to other diets, and EDNDF of both TMRs was higher than that of control diet due to the increased parameters b (p<0.039) and c (p<0.006) in TMR treatments. Whole track digestibility of most components in the TMRs was slightly increased compared to that in control diet, and RS-TMR had a tendency to be increased whole track digestibility except for NDF compared to BS-TMR. Based on the results observed from the present study, nutrient availability of whole crop silage based TMR looked slightly better than conventional separate feeding of concentrate and rice straw, mainly due to the improved stabilization of fermentation in the rumen and increased NDF digestibility of whole crop silage in TMR.

Feeding trial was conducted with 80 Hanwoo steers (7.5 months of age, 204.4 kg body weight) for 680 days from growing period to late fattening period to examine the feeding value of whole crop barley silage TMR (BS-TMR) and whole crop rye silage TMR (RS-TMR) on body gain, feed cost, slaughter characteristics and quality characteristics of $longissimus$ $dorsi$ muscle. Dietary treatments were conventional separate feeding of concentrate and rice straw (control), feeding BS TMR up to middle fattening period and same diet as for control during late fattening period (BS-TMR I), feeding BS-TMR for whole experimental period (BS-TMR II), feeding RS TMR up to middle fattening period and same diet as for control during late fattening period (RS-TMR I) and RS TMR for whole experimental period (RS-TMR II). Sixteen castrated calves were assigned to each treatment (4 pens, 4 heads per pen). Pens in each treatment were randomly distributed. Feeding both BS silage TMR and RS silage TMR slightly increased body gain of Hanwoo steers at the stages of growing and early fattening, and increased (P<0.0001) at middle fattening compared to feeding control diet while control diet tended to increase body gain at late fattening stage compared to feeding BS-TMR I, BS-TMR II and RS-TMR I diets. Total body gain was slightly increased in Hanwoo steers fed both I and II for BS and RS TMR compared to that in control diet. Feed cost per kg gain per head was relatively low in the Hanwoo steers fed silage TMRs to that fed control diet. Carcass weight, back fat thickness and $longissimus$ $dorsi$ area of Hanwoo steers tended to increase but lowered (P<0.047) yield index by feeding silage TMRs. Feeding BS TMR slightly decreased marbling score but no difference was found in the number of head over grade 1 between diets. Control diet tended to improve yield grade compared to silage TMRs. Chemical composition, water holding capacity, drip loss, cooking loss and pH, color and fatty acid composition of $longissimus$ $dorsi$ were not affected by experimental diets and feeding duration of silage TMRs. Shear force, however, was increased (P<0.046) by silage TMRs without difference between them compared to control diet. Based on the results of the current study, BS TMR and RS TMR could improve body gain and reduce feed cost without deteriorating meat quality compared to separate feeding of concentrate and rice straw. Overall feeding value was similar between BS TMR and RS TMR.
