A review of canola meal as an alternative feed ingredient for ducks
Wickramasuriya, Samiru Sudharaka,Yi, Young-Joo,Yoo, Jaehong,Kang, Nam Kyu,Heo, Jung Min Korean Society of Animal Science and Technology 2015 한국축산학회지 Vol.57 No.9
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 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.

Objective: The present study examined the effects of exogenous emulsifiers and multienzyme supplementation into a low energy density diet on growth performance, visceral organ parameters, blood metabolites, ileal morphology, and nutrient digestibility in broiler chickens from hatch to 21 days. Methods: One hundred and sixty-eight one-day-old Ross 308 broiler chickens were allocated in a completely randomized design to 24 pens and each pen was assigned to one of four dietary treatments to give six replications with seven chickens in a cage. Dietary treatments were: i) positive control with standard energy level (PC); ii) negative control with 100 kcal/kg lower energy of the standard level (NC); iii) NC diet supplemented 0.05% calcium stearoyl-2 lactylate as an emulsifier (NC+E); and iv) NC diet supplemented with both 0.05% calcium stearoyl-2 lactylate and 0.05% multi-enzyme (NC+E+M). Corn and soybean meal-based control diets containing vegetable oil were formulated to meet the Ross 308 nutrition specification. Chickens were fed ad-libitum with the treatment diets and sampling was conducted on day 21. Results: Our results revealed that emulsifier and multi-enzyme supplementation into NC diets improved (p<0.05) feed efficiency of the broiler chickens compared to the broiler chickens fed NC diets from hatch to 21 days. Supplementation of emulsifier and multienzyme into NC diet improved (p<0.05) nutrient digestibility of the broiler chickens. However, emulsifier and multi-enzymesupplementation into diet did not influence (p>0.05) visceral organ weight, blood metabolites, and intestinal morphology in broiler chickens fed NC diets. Conclusion: Supplementation of emulsifier and multi-enzyme in the NC diet would support improving growth performance in young broiler chickens with improved feed efficiency and increased nutrient digestibility thereby curtailing the negative impact of energy reduction in the diets.

<P><B>SUMMARY</B></P> <P>Feed enzymes are used in poultry diets to enhance nutrient availability and thereby improve growth performances of the birds. The objective of the present study was to investigate the effect of dietary Multi-Carbohydrase (<B>MC</B>) supplementation on growth performance, blood metabolites, visceral organ weights, gut morphology, and nutrient digestibility in broiler chickens. A total of 168 one-day-old broiler chicks (47.5 ± 0.20 g) were randomly allocated into one of four dietary treatments in a 2 × 2 factorial arrangement with 6 replications per treatment. Dietary treatments were as follows: (1) positive control (<B>PC</B>; energy sufficient, 3,200 ME, kcal/kg); (2) negative control (<B>NC</B>; energy deficient, 3,100 ME, kcal/kg); (3) PC with MC (MC; Superzyme-CS™; 0.05%); (4) NC with MC. Greater ADG (<I>P</I> = 0.022) was observed with the birds fed MC for the entire period (1–35 d) compared to birds fed a diet without MC. Birds fed the NC diet supplemented with MC showed improved FCR (<I>P</I> = 0.037) compared to birds fed the NC diet during the starter period (1–21 d). MC supplementation increased dry matter (<I>P</I> = 0.029), crude protein (<I>P</I> = 0.015), and energy digestibility (<I>P</I> = 0.015) of the birds compared to those fed a diet without MC on day 21. Moreover, birds fed a diet with MC had increased (<I>P</I> = 0.037) dry matter digestibility on day 35 compared to its counterpart, regardless of dietary energy level. Therefore, our study indicated that MC improved growth performance along with nutrient digestibility in broiler chickens fed corn soybean-meal-based diets containing wheat and wheat by-products from hatch to 35 d of age, regardless of dietary energy level.</P>

<P>A study was conducted to determine the apparent metabolizable energy (AME) requirement of Korean native ducklings for hatch to 21 d of age. A total of 336 one-day-old male Korean native ducklings were used in a completely randomized design having 8 dietary treatments to provide a range of AME content from 2,600 to 3,300 kcal/kg (i.e., 100 kcal/kg disparity). Eight experimental diets containing varying levels of AME were formulated to meet the NRC (1994) nutrient specifications. Ducklings were randomly allocated to 48 pens (6 replicates per treatment and 7 ducklings per pen) and were offered their respective diets on an ad libitum basis for the period of study. Body weight and feed intake were measured weekly to calculate feed conversion ratio, energy intake, and protein intake. Two ducklings per pen (n = 6) were euthanized via cervical dislocation to weigh empty body and drumsticks at the conclusion of the experiment. Data were fitted to both linear-plateau and quadratic-plateau models for estimation of the AME requirements for Korean native ducklings for hatch to 21 d of age. The estimated AME requirements were 2,953, 3,007, and 2,950 kcal AME/kg diet for maximum daily gain, daily feed intake, and for minimum feed conversion ratio, respectively.</P>

Objective: An experiment was conducted to investigate the response of laying hens fed corn distiller's dried grains with solubles (DDGS) that are naturally contaminated with deoxynivalenol (DON). Methods: One hundred and sixty 52-week-old Lohmann Brown Lite hens were randomly allotted to five dietary treatments with 8 replicates per treatment. The dietary treatments were formulated to provide a range of corn DDGS contaminated with DON from 0% to 20% (i.e., 5% scale of increment). All laying hens were subjected to the same management practices in a controlled environment. Body weight, feed intake and egg production were measured biweekly for the entire 8-week experiment. The egg quality was measured biweekly for 8 weeks. On weeks 4 and 8, visceral organ weights, blood metabolites, intestinal morphology, and blood cytokine concentrations were measured. Results: The inclusion of corn DDGS contaminated with DON in the diet did not alter (p>0.05) the body weight, feed intake, hen-day egg production, egg mass and feed efficiency of the laying hens. No difference was found (p>0.05) in the egg quality of hens that were fed the dietary treatments. Furthermore, hens that were fed a diet containing corn DDGS contaminated with DON showed no change (p>0.05) in the visceral organ weights, the blood metabolites, and the cytokine concentrations. The crypt depth increased (p<0.05) as the amount of corn DDGS contaminated with DON increased. Proportionately, the villus height to crypt depth ratio of the laying hens decreased (p<0.05) with the increasing level of corn DDGS contaminated with DON in the diet. Conclusion: The inclusion of corn DDGS contaminated with DON up to 20% in layer diets did not cause changes in egg production performance and egg quality, which indicates that DON is less toxic at the concentration of 1.00 mg DON/kg.

Objective: To evaluate calcium stearoyl-2 lactylate (CSL) performance as an exogenous emulsifier together with lipase for broiler diets. Methods: In total, 252 one-day-old Ross 308 broiler chickens were allocated in a completely randomized design to give 6 replications per treatment with 7 birds in each cage. There were six dietary treatments representing a 2×3 factorial arrangement consisted of two energy levels (standard energy [positive control, PC] and -100 kcal/kg of the requirement level [negative control, NC]) and three dietary treatments (without additives [CON], CON+CSL [CSL], and CON+CSL+lipase [CSL-Lipase]). Corn and soybean meal-based experimental diets containing vegetable oil were formulated. Growth performance, blood parameters, visceral organ weights, ileal morphology, nutrient digestibility, and cytokine gene expression were measured. Results: Birds fed a diet including CSL increased (p<0.05) lipase level in blood compared to birds fed a diet including CSL-Lipase on day 21. Similarly, higher (p<0.05) liver weight was observed in birds fed a diet including either CSL or CSL-Lipase on day 21. Birds fed NC diet with CSL improved (p<0.05) nutrient digestibility compared to the NC diet on day 21. However, birds fed a diet supplemented with CSL or CSL-Lipase did not affect (p>0.05) the weight gain, feed efficiency, ileal morphology, and cytokine concentrations during the experiment period, regardless of dietary energy levels. Conclusion: Our results indicated that CSL has a role in improving nutrient digestibility in young birds when supplemented to a corn-soybean meal based broiler diet.

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.
