Abstract

The objective of this experimental was to investigate the effect of dietary Cu-sulfate and Cu-soy proteinate on productive performance and small intestinal microflora. A total 1,000 Hy-Line Brown laying hens (35 weeks old) were randomly allotted to 1 of 5 dietary treatments: Control, Cu-sulfate 50, 100 (50, 100 ppm Cu supplementation as Cu-sulfate) and Cu-SP 50, 100 (50, 100 ppm Cu supplementation as Cu-soy proteinate). Each treatment was replicated 4 times with fifty birds per replication, housed in 2 birds cages. Fifty birds units were arranged according to randomized block design. Feeding trial lasted 5 weeks under 16L : 8D lighting regimen. Hen day egg production was significantly (P<0.05) higher in Cu treated groups than control. Feed intake, broken and shell-less egg production was not significantly influenced by treatment. Eggshell color, eggyolk color, haugh unit, and eggshell thickness were not significantly influenced by treatment. However, eggshell strength was significantly (P<0.05) greater in Cu treated groups than control. Concentration of copper of liver was significantly (P<0.05) greater in Cu treated groups than control. Concentration of zinc and iron of liver were not influenced by treatments. Population of Cl. perfrigens and Lactobacilli in the small intestinal content were significantly (P<0.05) influenced by treatments. Population of Cl. perfrigens decreased and that of Lactobacilli increased in the Cu supplement groups. In conclusion, dietary Cu sulfate and Cu-soy proteinate similarly improves egg production, eggshell strength, and favors intestinal microbial population of laying hens.

본 실험은 Cu-sulfate와 Cu-soy proteinate(Cu-SP)가 산란계의 생산성과 소장 내 미생물 균총에 미치는 영향에 대하여 조사하기 위해 실시하였다. 사양 시험은 35주령의 산란계(Hy-Line Brown) 1,000수를 선별하여 A형 2단 4열 케이지에 대조구 포함 총 5처리구로 구성하여 처리당 4반복, 반복당 50수씩(2수 수용 케이지 25개) 난괴법으로 임의 배치하였다. 시험 기간 동안 물과 사료는 자유 섭취하게 하였으며, 일반적인 점등관리(자연일조 + 조명; 16 hr)를 실시하였다. 시험구는 대조구, Cu-Sulfate 50(Cu-sulfate로 Cu 50 ppm), Cu-sulfate 100(Cu-sulfate로 Cu 100 ppm), Cu-SP 50(Cu-soy proteinate로 Cu 50 ppm), Cu-SP 100(Cu-soy proteinate로 Cu 100 ppm) 총 5처리였다. 일계 산란율(Hen-day egg production)은 구리 첨가구들이 대조구와 비교하여 유의적(P<0.05)으로 높았으나. 사료 섭취량은 처리 간에 유의적인 차이는 나타나지 않았다. 사료 요구량은 처리구 간에 유의적인 차이는 나타나지 않았지만, 구리 첨가구들이 낮은 경향(P=0.08)을 보여 주었으며, 연파란율은 처리구 간에 유의적인 차이는 나타나지 않았으나, 난각 강도는 구리 첨가구들이 대조구와 비교하여 유의적(P<0.05)으로 증가하였다. 간 내 Cu 함량은 Cu-sulfate 100과 Cu-SP 100 첨가구가 대조구와 Cu-sulfate 50과 Cu-SP 50 첨가구와 비교하여 유의적(P<0.01)으로 높았으며, Cl. perfringens는 구리 첨가구들이 대조구와 비교하여 유의적(P<0.01)으로 감소하였으나, 유익균인 Lactobacillus는 Cu-sulfate, Cu-SP 50 ppm 첨가구들이 대조구와 Cu-sulfate, Cu-SP 100 ppm 첨가구와 비교하여 유의적(P<0.05)으로 높았다. 결론적으로 Cu-sulfate와 Cu-SP는 산란계 산란율 개선에 있어서 비슷한 효과를 나타내었다.
