  • This study was carried out to enhance the nutritional value of whole crop corn silage and the utilization of animal waste as a ruminant feedstuffs. Whole crop corn were ensiled with cage layer excreta and concentrate. Treatments included whole crop corn silage (control), 10% cage layer excreta and concentrate-corn silage (CES lo), 20% cage layer excreta and 10% concentrate-corn silage (CES 20) and 30% cage layer excreta and 10% concentrate-corn silage (CES 30). The characteristics of silage fermentation was evaluated. Digestibility and palatability of the silage were observed through the feeding trial with four male Corridale sheep. The results obtained are summarized as follows: 1. Cage layer excreta-corn silage showed higher contents of crude protein and crude ash than control silage, while crude fibre content was significantlv lower than that of control silage (P(.01). 2. Total nitrogen and ammonia nitrogen content of the cage layer excreta-corn silage was significantly (P< .01) higher than that of control, but CES 10 silage was good in quality. 3. Lactic acid content of CES 10 silage was the highest, but that of CES 20 and CES 30 silage was lower than that of control. CES 20 and CES 30 silage was lower lactic acid content and higher pH than control. Therefore Flieg's score was wrose than that of control silage. 4. The numbers of total bacteria and lactic fermentation bacteria were estimated lo7-10' and 10"1OH, respectively, and there were no significant differences among treatments. Coliform numbers were not detected with CES 10 silage while were detected lo3 per gram in CES 30 silage. 5. Digestibility of crude protein, crude fibre and ADF was improved significantly in the animals fed the cage layer excreta-corn silage compared with animals fed the control silage. DCP and TDN were the highest in the CES 10 silage. 6. The intake of daily nitrogen and dry matter per metabolic body weight was the highest in animals fed the CES 10 silage.lage.

  • The effects of formic acid and formaldehyde treatment and methionine supplementation to ladino clover fibrous residue silage on eating and rumination behaviour were studied in sheep. From the ladino clover fibrous residue, two silage were prepared, either untreated or treated with formic acid and formaldehyde. Four experimental diets: untreated silage, treated silage, untreated silage with supplementation of methionine and treated silage with supplementation of methionine, were offered to four sheep at a restricted level of DM intake (2% of BW/d) twice daily in a two-way layout design. Methionine supplementation with the treated silage significantly (p < 0.05) reduced daily time spent eating, and consequently, markedly increased rate of eating. However, there was little effect of methionine supplementation on the daily time spent eating and eating rate for sheep offered untreated silage. Methionine supplementation with the treated silage reduced daily time spent ruminating, although the same effect was not observed for untreated silage. The rumination index (time spent ruminating/100 g DM eaten) was remarkably smaller (p < 0.05) with methionine supplement in feeding treated silage, although it did not differ for sheep offered untreated silage. There were no clear effect of methionine supplementation on the rumination efficiency (i.e. number of chews/bolus, bolus time and rumination chewing rate) both feeding untreated silage and treated silage.

  • This study was carried out to investigatigate feed cost of com-manure silage and growth performance of Korean native goats which was fed com-manure silage. The average weight about 11.6 kg of twenty one Korean native male goats (4 months used to determine the effect of the feeding trial. The goats were individually reared in metabolism cages and fed diet daily of 2% of the body weight on the dry matter basis. The treatments were divided into whole crop com silage(CS silage), whole crop com ensiled with cage layer manure (CLM; Com-manure silage or MS silage) and whole crop com silage supplemented with urea at feeding time (US silage). The content of crude protein, lactic acid and the ratio of ammonia nitrogen to total nitrogen ($NH_3-N/Total$ N) in MS silage were increased from 7.7 to 14.9%, 5.7 to 7.5% and 8.2 to 16.6%, and the differences were significantly (p < 0.05) different in all observations. Total body weight gain of those goats for 90 days was 6.0 kg (66.7 g/day; MS silage 4.3 kg (47.8 g/day; US silage) and 3.9 kg (43.4 g/day; CS silage), and feed conversion of MS silage (5.98) for 90 days was increased by far the best in the other groups and decreased about 30% in proportion to CS silage. Feed cost per 1 kg MS silage (1,606 won) was the lowest (p < 0.05) in the body weight gain and cut down expenses than fed CS silage by 37% of feed cost.

  • In order to solve the shortage of roughage supply for dairy farm in Korea, the mechanized model system for the production of winter cereal wrap silage in the fellow paddy field was developed in the previous studies. In this study, storage properties after long term storing of the winter cereal wrap silage were investigated. Also, the qualities of the wrap silage which was stored during 4 months were evaluated by sensory testings, analyzing chemical properties(moisture content, pH and organic acids) and investigating the increase of feeding value. The result of this study were summarized as follows; 1. After 300 hours storage, the acid level of the silage decreased slowly to 4.6 -4.8 pH. Also, the temperature was stabilized around 27-28$^{\circ}C$. The silage having below 5.0 pH is a desirable level for the most of good silage. 2. According to the sensory test and chemical property analyzation it was evaluated as the first class silage like a com silage. 3. Also, when the wrap silage are fed to the cattle, the cattle produced milk more 25% than that of conventional feed. 4. As an overall conclusion, winter cereal wrap silage in the fallow paddy field cm be one of the major roughage source in replacement of com and other conventional silage to dairy cattle in Korea.

  • Preservation of forage crops as silage offers opportunity to avoid the high risk of rain-damaged hay in the humid south-central USA. Recent developments with baled silage or baleage make silage a less expensive option than typical chopped silage. Silage has been important in the region primarily for dairy production, but baleage has become an option for the more extensive beef cattle industry in the region. Silage samples submitted to the Louisiana State University Agricultural Center Forage Quality Lab from 2006 through 2013 were assessed for dry matter (DM) and forage nutritive characteristics of chopped silage and baleage of the different forage types from commercial farms primarily in Louisiana and Mississippi. Of the 1,308 silage samples submitted, 1,065 were annual ryegrass (AR) with small grains (SG), the warm-season annual (WA) grasses, sorghums and pearl millet, and the warm-season perennial (WP) grasses, bermudagrass and bahiagrass, providing the remaining samples. Concentration of DM was used to indicate an effective ensiling opportunity, and AR silage was more frequently within the target DM range than was the WA forage group. The AR samples also indicated a high-quality forage with average crude protein (CP) of 130 g/kg and total digestible nutrient (TDN) near 600 g/kg. The cooler winter weather at harvest apparently complicated harvest of SG silage with chopped SG silage lower in both CP and TDN (104 and 553 g/kg, respectively) than either AR silage or baleage of SG (137 and 624 g/kg for CP and TDN, respectively). The hot, humid summer weather along with large stems and large forage quantities of the WA grasses and the inherently higher fiber concentration of WP grasses at harvest stage indicate that preservation of these forage types as silage will be challenging, although successful commercial silage samples of each forage type and preservation approach were included among samples of silages produced in the region.

  • Two trials were carried out during two different grazing seasons to evaluate effect of grass silage supplementation, when amount of pasture is limited on dry matter intake (DMI), milk production, and gross energetic efficiency (GEE) of grazed lactating cows on a high forage-based diet. Fifty-one Holstein cows were randomly assigned to one of two dietary treatments: high pasture group or high silage group. In the spring flush, pasture and silage DMI, milk yield, milk fat percentage, and GEE were not different between the dietary groups. After the spring flush, pasture and silage DMI were higher for the high silage group than for the high pasture group. After the spring flush, although these were the higher total DMI of the high silage group than the high pasture group, milk yield was significantly (p<0.05) higher for the high pasture group than the high silage group. Milk fat percentage tended to be higher for the high silage group than the high pasture group. The GEE was significantly (p<0.05) higher for the high pasture group than the high silage group during after the spring flush. This study indicated that supplementation of grass silage, especially after the spring flush, can have a significant effect of increasing of forage intake and maintenance of the milk fat percentage; but not increase milk yield and GEE.

  • The effects of supplementation of organic citrus on the quality of rice straw silage was investigated in this study. The aim of the study was to improve the quality of rice straw silage using agricultural by-products and therefore to secure the good quality forage sources. Firstly, looking at chemical composition of citrus added rice straw silage, crude protein content appeared improved with the addition of citrus to rice straw silage compared to control while NDF and ADF contents decreased. pH of the silages were different between control(4.39) and treatments$(3.47\sim3.53)$. Lactic acid content was higher in citrus added silage(4.87mM) than in control (3.65mM). External quality of the silages was also better in citrus added silage when citrus added at the equal ratio with rice straw(1 : 1). This trend was the same as with pH and lactic acid content. Propionate was significantly higher in citrus addd silage but butyrate was significantly lower. DM and NDF disappearance rates in the rumen were highest when citrus added at the equal ratio with rice straw(1:1). In conclusion, supplementation of citrus to rice straw silage with equal ratio contributed the best to the improvement of the quality of silage and it may have been due mainly to abundant content of non-structural carbohydrate in citrus.

  • To investigate the effects of molasses addition at ensiling on nutritional quality of wilted napier grass, chemical quality and nutrient composition of the silages, digestibility and nitrogen retention at feeding trials were analysed using 4 goats in a cross over design. The results are as follows : 1. Molasses addition at ensiling decreased pH value (3.99) and ammonia nitrogen, and increased lactic acid content by 285% compared to non-additive silage (83.5 g/kg dry matter). 2. There were no differences in digestibilities of dry matter, crude protein, neutral detergent fiber, acid detergent fiber, hemicellulose and cellulose between the silage ensiled with molasses (MS silage) and the silage ensiled without molasses (WS silage). Urinary nitrogen excretion, however, significantly (p<0.05) decreased in goats fed the MS silage, and nitrogen retention was positive in goats fed the MS silages, but negative in goats fed the WS silage. 3. Acetic acid concentration in remained fluids in goats fed the MS silage was lower and propionic and butyric acid concentrations were higher than those in goats fed the WS silage. As water soluble carbohydrate content was higher in the MS silage than in the WS silage, a part of added molasses was still remained in the silage at the feeding trials and could be utilized for energy sources by the goats. Nitrogen may be also effectively utilized in goats fed the MS silage, because the silage were inhibited in proteolysis during ensiling.
