Abstract

To investigate the effect of feeding rare earth (RE) on the performance of breeder hens a feeding trial with sixteen thousands of 158 day old Ross broiler breeder hens was conducted for thirty weeks. A mixture of RE- chlorides containing mainly La, Ce, and Pr was mixed into corn-soy based diet at two levels, 300 and 600 mg/kg, All the hens were housed in flat layer houses and the ratio of male to female was maintained at one to ten. Dietary supplementation of the of RE at a level of 300 mg/kg made the hens reach egg production peak higher by about 6% and earlier by about two weeks. As a result, it made higher hatchable egg production by 3.5%. It also reduced dramatically the mortality of both male and female breeders(P<0.05). Egg weight was slightly increased but egg qualify was not much influenced by dietary supplementation of RE. Egg albumin hight and Haugh unit were significantly improved while egg shell thickness, egg breaking strength and yolk color were similar to those of the control. Experimental results appeared to show a good possibility that egg fertility and hatchability were improved by feeding RE. Dietary supplementation of RE at a level of 300 mg/kg should be acceptable but not the 600 mg/kg level for breeder hens. Further studies on the effect of RE on egg fertility and hatchability appears to be necessary.

희토(稀土) 또는 rare earth(RE)라고 하는 것은 15개 란탄족 원소와 이트륨(Y) 그리고 스칸듐(Sc)을 합친 17개 원소를 총칭하는 화학 용어이다. 일부 희토 원소들의 생화학적 작용과 생물학적 기능이 인정됨에 따라, 산란계와 종계에 대한 급여 효과와 급여 수준을 알아보기 위하여 평사에서 산란초기 육계 종계(Ross SP) 16,231수를 대상으로 염화 희토 혼합물$(RECl_3)$을 가지고 30주 동안 사양 시험을 실시하였다. 본 시험에서 희토 사료 첨가는 300 mg/kg와 600 mg/kg, 두 수준이었는데, 후자는 여러 가지 시험 결과로 미루어 적정 첨가 수준을 초과하는 양으로 생각되었으며, 희토 300 mg/kg의 사료 첨가는 종계의 생산 능력을 크게 개선할 수 있는 가능성을 보여주었다 희토 급여 초기 약간의 스트레스가 있는 듯 하였으나, 피크 산란율에 도달하는 기간을 단축하고, 피크 산란율을 높게 그리고 길게 지속하는 효과가 있었으며, 산란 곡선의 탄력을 좋게 유지하였다. 희토 300 mg/kg의 사료 첨가는 부화에 이용할 수 있는 종란 생산을 3.5% 정도 증가시켰다. 또 하나 관찰된 괄목한 만한 결과는 희토가 종계의 폐사율을 크게 감소시켰다는 사실이다. 희토 사료 첨가는 숫 종계 폐사율을 33.2% 그리고 암 종계 폐사율을 46.5% 감소시키었다. 희토의 난질에 대한 괄목할 만한 효과는 관찰되지 않았다. 난각의 색이나 두께와 강도, 난황색 등은 대조구나 처리구 간에 차이가 없었고, 난중, 난백고, Haugh unit등은 유의하게(P<0.05)는 개선되는 경향을 나타냈다. 희토 급여의 수정을 및 부화율에 대한 본 시험의 결과는 기대했던 바와 같은 개선은 없었다. 34주령, 38주령, 그리고 50주령 모두 3회에 걸쳐 부화 시험을 실시하였는데, 38주령 때에만 소폭 유의한 수정율과 부화율 증가가 나타났고(P<0.05), 전체적으로는 대구나 희토를 급여한 것이나 차이가 없었다. 이 현상은 희토를 급여하지 않은 대조구의 계군에는 숫 종계 폐사율이 높아 대조구에는 혈기 왕성한 젊은 수탉이 지속적으로 편입된 반면, 희토를 급여한 계군에는 노계 수탉이 수용되어 번식능력이 낮았을 것으로 사료되므로 올바른 비교가 될 수 없을 것으로 생각되었다. 본 시험의 결과 종계 사료에 희토의 사료 첨가로 종계의 빠르고 높은 산란 피크 도달과 향상된 산란 지속성 유지, 그리고 현격한 종계 폐사율 감소 등 생산성을 개선하는 효과가 있음을 보여주었다. 그러나 희토가 수정율이나 부화율에 미치는 영향은 앞으로 좀더 연구가 필요하다.
