This study was designed to investigate the effects of multi-enzyme on diarrhea and immune responses of weaned pigs. A total 36 weaned pigs (5.92 ± 0.48 kg BW; 28 d old) were randomly allotted to 2 dietary treatments (3 pigs/pen, 6 replicates/ treatment) in a randomized complete block design. The dietary treatments were a typical diet based on corn and soybean meal (CON) and CON with 0.1% multienzyme (Multi; mixture of β-mannanase, xylanase, α-amylase, protease, β-glucanase, and pectinase). Pigs were fed their respective diets for 6 wk. Frequency of diarrhea, levels of packed cell volume (PCV), white blood cells (WBC), immunoglobulins, cortisol, tumor necrosis factor-α (TNF-α), transforming growth factor- β (TGF-β), and C-reactive protein (CRP) were measured. Multi group tended to decrease (p<0.1) diarrhea frequency than CON group during 2 wk after weaning. Lower values of PCV on d 3 (p<0.05) and d 7 (p<0.1) were found in Multi group compared with CON group. There were no significant differences on WBC number and immunoglobulin (Ig) M and A between Multi and CON groups. However, Multi group tended to increase (p<0.1) Ig G on d 7 than CON group. Moreover, Multi group showed modulated immune responses, indicated by decreased levels of cortisol (p<0.05) on d 7 and 14, TNF-α on d 3 (p<0.05) and d 7 (p<0.10), TGF- β on d 2 (p<0.05) and d 7 (p<0.10), and CRP (p<0.10) on d 3 and 7 after weaning compared with CON group. Consequently, inclusion of multi-enzyme in diets for weaned pigs improved gut health and modulated immune responses of weaned pigs.
本试验旨在研究复合酶对断奶仔猪腹泻及免疫应答的影响。共36头断奶猪(5.92±0.48 kg BW);试验采用完全随机区组设计，随机分为2个饲粮处理(3头猪/栏，6个重复/处理)。饲粮处理为典型的玉米豆粕(CON)为主饲粮和添加0.1%复合酶(Multi;β-甘露聚糖酶、木聚糖酶、α-淀粉酶、蛋白酶、β-葡聚糖酶和果胶酶的混合物)。各组猪分别饲喂饲粮6周。测定腹泻次数、堆积细胞体积(PCV)、白细胞(WBC)、免疫球蛋白、皮质醇、肿瘤坏死因子-α (TNF-α)、转化生长因子-β (TGF-β)、c反应蛋白(CRP)水平。断奶后2周，与对照组相比，多药组腹泻次数有降低的趋势(p<0.1)。与CON组相比，Multi组第3 d和第7 d PCV值均显著降低(p<0.05)。Multi组与CON组WBC数、免疫球蛋白(Ig) M、A无显著差异。但与CON组相比，Multi组在第7天Ig - G有升高的趋势(p<0.1)。与CON组相比，Multi组断奶后第7、14天皮质醇(p<0.05)、第3、7天TNF-α (p<0.05)、第2、7天TGF- β (p<0.05)、第3、7天CRP (p<0.10)水平均有所降低。因此，在断奶仔猪日粮中添加多酶可改善仔猪肠道健康并调节其免疫反应。

Pigs were fed their respective diets for 6 wk. Measurements were growth performance, morphology of ileum, apparent ileal digestibility and apparent total tract digestibility of dry matter, crude protein, and energy of weaned pigs. There were no significant differences on growth performance during overall experimental period. No differences were found for the morphology of ileum and nutrient digestibility between CON and Multi groups. Therefore, the results in the current study indicated that multi-enzyme supplementation in diets had no effects on growth performance, intestinal morphology, and nutrient digestibility of weaned pigs.

In general, an increase in consumer income increases interest in safe foods and increases consumption of environmental friendly foods. Meanwhile, even in Malawi, interest in safe food and environmentally friendly food has been increasing due to increase in per capita income, but research related to this has not been done yet. The purpose of this study is to estimate the value of environmentally friendly foods in Malawi consumers. For this purpose, we surveyed the consumption patterns and estimated the value of organic chicken for consumers visiting supermarkets. As a value estimation technique, Contingent Valuation Method (CVM) was used. Probit model analysis showed that price, expenditure on regular chicken, and knowledge of organic food affect the willingness to pay for organic chicken. CVM analysis shows that Malawi supermarket consumers are willing to pay MK2,514 (3.59) dollars per kilo of organic chicken, which is 25.7% higher than the average price of a regular chicken. Thus, Malawi supermarket consumers can deduce that they have a higher value for environmentally friendly food than regular food. These findings can be used in formulating policies on food safety by government officials, organic chicken meat marketing strategies by supermarket mangers, decision making to enhance organic food production by producers, in order to develop organic food industry.
