  • An experiment was conducted to study the nutritional quality of whole crop corn silage ensiled with cage layer manure in sheep. Treatments were designed as a $3{\times}3$ Latin square with 16-day periods. Sheep were allotted in one of three diet-treatments, which were whole crop corn silage (CS), whole crop corn+30% cage layer manure (CLM) silage (based on DM; MS) and rice straw+concentrate (SC) mixed at 8:2 ratio (on DM basis). Silage ensiled with CLM significantly increased (p<0.05) digestibilities of crude protein, NDF and ADF, TDN over the other treatments. Ruminal pH in sheep fed SC was significantly (p<0.05) higher than that of the other diets at 0.5, 1, 2, 4 and 8 h after feeding. Ruminal ammonia nitrogen concentration of the MS treatment was significantly (p<0.05) higher than that of the other treatments at 0, 1, 2 h after feeding. The MS treatment highly increased (p<0.05) feed intake, digestibility of organic matter and crude protein, nitrogen intake and retained nitrogen. The MS treatment highly increased (p<0.05) purine derivative (PD) excretion leading to higher microbial protein synthesis.

  • With the purpose to utilize cage layer manure (CLM), whole crop corn forage was ensiled with 30% CLM (MS silage) and without CLM (CS silage). MS silage was significantly (p < 0.05) higher in pH value, total VFA, propionic and butyric acids, and the ratio of ammonia nitrogen to total nitrogen, but lower (p < 0.05) in lactic acid and water soluble carbohydrate (WSC) contents than CS silage. Digestibility was evaluated using Shiba strain Japanese goats. Urea was supplemented to CS silage at feeding to adjust nitrogen intake to MS silage (US silage). There were no differences in digestibilities of dry matter (DM) and energy among the three silages. However, US silage showed higher (p < 0.05) digestibility of crude protein, but digestibilities of NDF, ADF, hemicellulose and cellulose were higher (p < 0.05) in MS silage. Nitrogen retention was positive in US and MS silages, but it was negative in CS silage. Voluntary feed intake of goats was 11.02, 12.03 and 13.34 g of DM per metabolic body weight ($kg^{0.75}$) for 10 minutes, for CS, US and MS silages, respectively.

  • In situ degradability and fermentation characteristics in the rumen of goats fed whole crop corn forage ensiled with (MS silage) or without (CS silage) 30% of cage layer manure (CLM) were investigated. The two silages were well preserved. To adjust nitrogen intake of CS silage to that of MS silage, the 3rd group of goats was given urea with CS silage at feeding time (US silage). Each goat was given a diet of 2% of the body weight (dry matter basis) daily. In situ degradability of dry matter (DM) and crude protein (CP) of MS silage in the rumen were higher than those of CS and US silages. Total potentially degradable portions of DM and CP in MS silage were also higher than those in CS and US silages. Blood urea nitrogen and rumen ammonia nitrogen concentration of goats fed US and MS silages were significantly (p<0.05) higher than those of goats fed CS silage. Acetic, propionic and butyric acids in ruminal fluids of goats fed MS silage were significantly (p<0.05) higher than those of goats fed CS and US silages.

  • 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.
