With the development of artificial intelligence (AI) and 5G technology, an ecosystem of digital content is gradually becoming intelligent, immersive, and convergent. However, there is not enough ultra-realistic content for the ecosystem. For ultra-realistic content services, creative content technologies using AI are being developed. This paper introduces the trends in and prospects of creative content technologies such as 3D content creation, digital holography, image-based motion recognition, content analysis/understanding/searching, sport AI, and content distribution.

단위가축영양 : 생약제제 ( Miracle20(R) ) 가 육계의 생산성과 영양소 이용률 , 소장내 미생물 균총 및 면역기능에 미치는 영향

An experiment was conducted to investigate the effects of supplementary herbal products [Miracle20^ⓡ(M20)] on the performance, nutrient digestibility, small intestinal microflora and serum IgG level in broiler chickens. One thousand one-day-old broiler chickens(Ross^ⓡ) were assigned to five treatments: control(T1), 50ppm chlorotetracycline(CTC; T2), 0.2% M20-S(T3), 0.2% M20-D(M20-S fortified in Angelica gigas, Dioscorea japonica and Schizandra chinensis; T4), 0.2% M20-A(M20-S minus Schizandra chinensis and plus Plellidendron amurense; T5). Each treatment had four replications (two for each sex) of 50 birds. Growth performance was not significantly affected by dietary treatments. The herbal products supplementation tended to improve the weight gain of male broiler chicks, but showed no significant difference. Nutrient digestibilities and ammonia gas level on the litter were not significantly affected by treatments. The colony forming unit(CFU) of CI. perfringens in small intestine was significantly lower in treatments T2 and T5 at 26 days of age while the CFU of E. coli was significantly lower in T3 compared to T1 at 42 days of age(P$lt;0.05). The level of serum IgG tended to increase with dietary herbal products supplementation. These results indicate that dietary herbal products(M20) do not significantly affect growth performance and nutrient digestibilities in broiler chickens but have positive effects on small intestinal microflora and serum IgG level.

단위가축영양 : 사료 내 Cu 및 Zn - Methionine Chelates 첨가가 육계의 생산성에 미치는 영향
홍성진(S. J. Hong),임희석(H. S. Lim),백인기(I. K. Paik) 한국축산학회 2002 한국축산학회지 Vol.44 No.4
An experiment was conducted to investigate the effects of supplemental copper or/and zinc methionine chelates(Cu-Met or/and Zn-Met) on the performance, nutrient digestibility, serum IgG level, gizzard erosion, and the contents of Cu and Zn in liver and excreta of broiler chickens. One thousand d-old broiler chickens (Ross^R) were assigned to 4 treatment; control, 100 ppm Cu in methionine chelate(Cu-Met), 100 ppm Zn in methionine chelate(Zn-Met) and 100 ppm Cu plus 100 ppm Zn in methionine chelate(Cu-Zn-Met). Each treatment had five replications of 50 (25 male + 25 female) birds each. Average weight gains of chicks fed chelated Cu or/and Zn were significantly higher than that of chicks fed the control (P<0.05). Moreover, feed conversion rates of chicks were better in the chicks fed chelated Cu or/and Zn than in the chicks fed the control (P<0.05). The birds fed the chelated Cu and Zn(Cu-Zn-Met) tended to perform the best growth rate and feed conversion rate. Nutrient digestibilities were not affected by the dietary treatments. Serum IgG level of chicks fed Cu-Zn-Met was significantly higher than that of chicks fed the control (P<0.05). Gizzard erosion index was not significantly different among the treatments. The contents of Cu and Zn in liver were not significantly affected by the dietary treatments. The excreta contents of Cu or/and Zn were significantly high in the birds fed supplementary Cu or/and Zn. It was concluded that dietary supplementation of Cu or/and Zn in methionine chelated form improved growth and feed conversion efficiency of broilers.
