Open Access : A review of canola meal as an alternative feed ingredient for ducks
( Samiru Sudharaka Wickramasuriya ),( Young Joo Yi ),( Jaehong Yoo ),( Nam Kyu Kang ),( Jung Min Heo ) 한국동물자원과학회(구 한국축산학회) 2015 한국축산학회지 Vol.57 No.29
This review provides an overview of the published data on the canola meal and its suitability for duck as an alternative plant-origin protein source to soybean meal. Canola meal is a legume origin protein source containing comparable amino acid profile to soybean meal and rich in essential minerals and vitamins. Nonetheless, it is known to contain less in energy content than soybean meal. Factors like field conditions and processing methods creates compositional variations among canola meal. Presence of anti-nutritional factors such as phenolic substances, phytate and glucosinolates which are known to reduce growth performance in livestock animals, are the major drawbacks for canola meal to be a competitive plant-origin protein source in the feed industry. This review is focused to address i) nutritional characteristics and feeding value of canola meal for ducks and ii) impacts of feeding canola meal on performances of ducks.

The effect of Multi-Carbohydrase (MC) supplementation on growth performance, visceral organ weights, blood metabolites, jejunum morphology, nutrient digestibility, and carcass parameters of broiler chickens fed nutrient-deficient corn soybean-meal based diets containing high levels of non-starch polysaccharides from wheat and wheat by-products was investigated. A total of 378 one-day-old Ross 308 broiler chickens were randomly assigned to one of seven dietary treatments to give six replicates per treatment (nine birds per pen). Dietary treatments were as follows: (1) positive control (PC; commercial standard diet); (2) negative control 1 (NC-1; PC-120 kcal/kg metabolizable energy); (3) NC-2 (PC-3% standardized ileal digestibility [SID] amino acids). The remaining four dietary treatments were formulated with the addition of MC (MC; Superzyme-CS™) into two negative controls along with two supplementation levels of MC (i.e., 0.025% and 0.05%, respectively). Improved body weight, average daily gain, and feed conversion ratio (p < 0.05) were observed in broiler chickens fed a reduced energy diet supplemented with MC compared to birds fed NC-1 diet from days 1-35. Additionally, birds fed a reduced energy diet with 0.05% MC showed comparable (p > 0.05) growth performance with birds fed PC for 35-day post-hatch. Furthermore, the addition of MC into reduced amino acid diets improved (p < 0.05) growth performance. Broiler chickens fed MC supplemented nutrient-deficient diets showed a greater (p < 0.05) villus height to crypt depth ratio than birds fed diets without MC on days 21 and 35. Similarly, improved (p < 0.05) nutrient digestibility was observed in birds fed reduced energy diets supplemented with MC compared to birds fed NC-1 on days 21 and 35. Our results suggest that MC supplementation into reduced energy or reduced amino acid diets containing wheat and wheat by-products has the potential to improve growth performance and nutrient digestibility while maintaining healthier gut morphology in broiler chickens from 1 to 35 days of age.

본 논문은 유채박에 관련한여 발표된 정보들의 개요와 더불어 오리에게시 대두박을 대체할 식물성 단백질 공급원으로써의 유채박의 적합성을 제시하고자 작성 하였다. 유채박은 두과 식물 단백질 사료로 대두박과 유사한 아미노산 함량을 가지조 있으며 또한 필수 미네랄과 필수 비타민을 다량 함유하고 있다. 비록 상대적으로 대두박에 비해 에너지 함량이 낮은 것으로 알려졌으나, 토양의 환경과 가공 방법은 유채박의 구성 영양소에 변화에 영향을 미치는 것으로 알려졌다. 유채박의 phenolic substances, phytate 그리고 glucosinolate와 같은 항영양요소들은 동물의 성장은 저해 시키는 것으로 알려져 있는데, 이것은 유채박이 원료 사료로써의 가치를 시키는 중요한 요소로 지목 되고 있다. 본 논문은 1) 유채박의 영양적 특성과 오리 사양 시 유채박의 원료사료로써의 가치 그리고 2) 유채박 급이 시에 오리의 성장률과 도체품질에 대한 영향에 대하여 중점적으로 논하고 있다.

The production performance and egg quality traits among five strains of Korean native chickens (KNC) were evaluated in conventional cages. A total of 240 KNC were housed in a controlled environment. Each strain had 12 replicates with 4 chickens per cage. Feed intake, body weights, egg production and egg quality were measured at 24, 28 and 32 of weeks. Egg quality parameters were analyzed using 150 eggs. Results indicated significant (P<0.05) difference in average body weights, egg production and egg weight among five strains of KNC. In contrast, KNC strains effect was non-significant (P>0.05) for feed efficiency. The difference among those KNC strains on egg shell color, egg shell strength and egg shell density were not different (P>0.05) at the age of week 24 while it was significant (P<0.05) at the age of week 28 and 32. There was no effect (P>0.05) on egg length and egg shape index from five strains of KNC. The significant difference (P<0.05) was observed in egg width with KNC strains during early ages (week 24 and 28) and it was not significant (P>0.05) at the age of 32 weeks. Regarding internal quality parameters, albumen height and Haugh unit were significantly (P<0.05) affected with KNC strains while the effect on yolk color was not significant (P>0.05). Based on the egg weight and the production performance, GS-10 KNC strain was superior when compared with the other strains.
