한인규,이봉덕,최진호 ( In K . Han,B . D . Lee,J . H . Choi ) 한국축산학회 1973 한국축산학회지 Vol.15 No.2

Experiments were carried out with 280 each of Starcross layer chicks and Starbro broiler chicks to examine the nutritive value of a local antibiotic byproduct (Vigofac) as a source of Unknown Growth Factor (UGF) and to determine its optimum levels in broiler and chick starter diets. The results obtained are summarized as follows; Crude protein content of Korean Vigofac was 20-24% and it was rich in all essential amino acids but methonine. It also contained a considerable amount of oxytetracycline and vitamin A. 2. Supplementation of both chick starter and broiler starter diet with Vigofac gave a little improvement in growth rate at the feeding level of 1%. However, supplementation of more than 1% of Vigafac depressed the growth rate, although statistical significance was not found. 3. It was found that there was an effect of Vigofac on feed efficiency (P$lt;0.05). It might be concluded that Vigofac can be used at a level as high as 7%$gt; although the greatest efficiency was obtained at 1% level. 4. Nitrogen retention and utilizabilities of dry matter, crude fat and nitrogen free extract were relatively high with chicks fed 5% level of Vigofac. 5. The present data suggest that Vigofac can replace the same amount of corn, wheat bran or perilla oil meal in chicken diets without any adverse effect.

한인규,오상집,하종규,김춘수 ( In K . Han,Sang J . Ohh,Jong K . Ha,Chun S . Kim ) 한국축산학회 1978 한국축산학회지 Vol.20 No.2

Two experiments were conducted to study the effects of use of Feedrectar on the growing performances of young pigs (Expt. I) and broiler chicks (Expt. II). In the Experiment I, 200 crossbred baby pigs weighing approximately 11㎏ of body weight mere used in five treatments of Feednectar 0%, Feednectar 0.05%, Feednectar 0.1%, sucrose 2% and a palatability-testing groups during 4 weeks of experimental period. In the Experiment II, a total of 270 broiler chicks of Shaver strain were employed in three treatments consisted of 0%, 0.05%, 0.1% of Feednectar for a period of 8 weeks. The results obtained are summarized as follows: 1. It was found that the body weight gain of young pigs (9.4%) and broiler chicks (5.6%) was significantly (P$lt;0.05) improved when the Feednectar was added is the rations of these experimental animals at the level of 0.1%. 2. The amount of feed consumed by the experimental pigs and chicks was also consider ably (P$lt;0.05) increased as the level of Feednectar in the diets increased. 3. Present data indicated that the feed efficiency of animals fed Feednectar was also improved, although no statistical significance was found between treatments except 0.1%, Feedneetar fed broilers that showed significant difference at the level of 5%. 4. It was apparent that the addition of Feednectar at the level of 0.1% would be recommendable for better growing performances of early weaned pigs and broiler chicks. 5. Palatability test conducted by young pigs revealed that the addition of either Feednectar or sugar could improve the palatability of experimental diets. 6. Shark color of broiler chicks was slightly improved by the use of Feednectar, although the significant difference was not found. 7. It was found that the experimental chicks fed Feednectar utilized the dry matter, crude protein, crude fat and carbohydrate in the diet more efficiently than control group. 8. Protein loss in the rations of pigs and broilers was alway less for Feednectar added diet than control diet during the storage period.

저질 조사료의 사료가치 개선방안에 관한 연구

Approximately 450 scientific articles including over 20 review papers (mostly published in the last 2 decades) have been reviewed to evaluate and compare the nutritional characteristics of treated and untreated low quality roughages (mostly crop residues). Attempts have also been made to explain the possible mechanisms for the improvement in nutritive value of treated lignocellulosic materials and to expose some problems associated with various treatments. (1) Over 2,000 million metric tons of crop residues are produced every year in the world. Wheat straw (25.3%), rice straw (22.8%), corn stover (15.8%), sugar cane residues (14.4%) and barley straw (8.3%) are the major crop residues. Of total production of crop residues, Asia, North America, and Europe are producing 46%, 19% and 13%, respectively. Forty types of low quality roughage have been examined with regard to improving their nutritive value by various treatments. These can be listed as follows. A. Crap residues and agricultural by-products: Rice straw, oat straw, wheat straw, barley straw, corn stover, corn cobs, sunflower stover, sugar cane top, cassava wastes, cassava leaves, sorghum stover, millet stover, peanut hull, soybean residues, cotton by-product, cotton straw, pea straw, rice hull, sugar cane bagasse, cotton hull, and alfalfa stem. B. Wood and wood by-products: aspen, poplar, spruce, black ash, American basswood, yellow birch, eastern cottonwood, American elm, silver maple, sugar maple, red oak, white oak, quaking aspen, white birch, soft maple, and ponderosa pine. C. Native herbages: wild (native or range) grasses. D. Animal wastes: cow manure, poultry manure. (2) Most crop residues and low quality rough ages are nutritionally known to be low in energy, crude protein, calcium, phosphorus, some trace minerals and carotene and quite high in crude fiber, ADF, cellulose, hemicellulose, lignin and silica. Their digestibilities of cellulose and bioavailability of energy are low and voluntary feed intake is also low. Thus, most untreated lignocellulosic materials could not be classified as maintenance feeds of animals. (3) Since the Beckman method of sodium hydroxide treatment was developed in 1921, more than 30 treatment procedures were found to be effective in improving the nutritive value of low quality roughages. A. Physical treatments: soaking, grinding, steam pressure, explosion, irradiation, pelleting, and supplementation. 8. Chemical treatments: Beckman NaOH, wet chamber NaOH, Dip NaOH, spray NaOH, urine, urea, anhydrous ammonia stack, aqueous ammonia, calcium oxide (lime), calcium hydroxide, potassium hydroxide, sodium carbonate, sulphur dioxide, sodium chlorite, ozone, chelating metal caustic swelling, hydrogen peroxide, peracetic acid. C. Physico-chemical treatment: sodium hydroxide and pelleting. D. Biological treatments: fermentation, enzyme, silage, manure·silage. (4) Present review data reveal that chemical (36.2%), biological (36.2%), physical (31.1%) and physico-chemical treatments (30.3%) could all significantly improve the dry matter digestibility of low quality roughage. It was found that percent improvement in feed intake for the physico-chemical treatment (51.20 was much higher than biological (40.8%), physical (32.5%) or chemical (31.0%) treatments. Physical (84.4%), chemical (84.9%), physico-chemical (51.5%) and biological (148.4%) treatments of crop residues had a more striking effect on the percent improvement in performances of ruminant animals than on the percent improvement in DM digestibility or feed intake. Supplementation (physical), sodium hydroxide, ammonia, urea/urine (chemical), silage and/or manure·silage (biological) treatments were the most practical and beneficial ways to improve the nutritive value of crop residues. Effects of various treatments on the chemical composition, digestibilities, characteristics of cell walls, feed intake, VFA production, ruminal pH, performance of animals and feed cost are summariz

In order to compare the nutritive values of locally produced tricalcium phosphate (TCP) with that of imported tricalcium phosphate(TCP), dicalcium phosphate(DCP) and that of bone meal when no fish meal was supplied, a total of 350 White Leghorn laying hens of 65 weeks old were fed for a period of 5 weeks. The results obtained are summarized as follows. 1. No differences were found in egg production rate, egg mass arid feed efficiency between various phosphate supplements, however, the control group receive no fish meal showed considerable decrease in egg weight, production rate and egg mass. 2. There was no difference in egg shell thickness, and content of Ca and P among various phosphate supplements, however, egg-shell thickness of control group was slightly thinner than that of inorganic phosphate fed group. The contents of Ca and P of egg-shell for the control group were lower than other groups. 3. The crude ash content of tibia was slightly decreased for both bone meal group and the control group, however, there were no differences between tricalcium phosphate groups and dicalcium phosphate group in the content of crude ash of tibia. The calcium and phosphorous contents of tibia of hens fed various phosphate supplements were higher than those of control group. 4. No difference were obtained in nutrient utilizability among various sources of phosphorus fed groups, However utilizability of dry matter and crude protein were slightly decreased for the control group. 5. The decrease in body weight during experimental period was observed for all then groups, especially was notable for the control group. The mortality observed during experimental period was not different among calcium phosphate groups, however, was slightly higher for the control group than the other groups. The results obtained from the present experiment showed that there were no differences in the nutritive value of locally produced TCP when was compared with imported DCP or TCP. It was also suggested that supplement of inorganic phosphorus for layers maybe very important when no fish meal was used in the laying rations.
