饲用酶制剂既能提高饲料的消化率和利用率,提高禽畜及鱼类的生产性能,又能减少禽畜排泄物中氮、磷的排泄量,保护水体和土壤免受污染。因此,饲用酶制剂作为一类高效、无毒副作用和环保型的绿色饲料添加剂,在21世纪具有十分广阔的应用前景。特此,本刊采访了夏盛实业集团有限公司杜仲平董事长和技术经理张博士,就酶制剂的实际应用、科技创新以及发展前景等问题为大家解答。 相似文献

"奶洒了,蛋打了",一把三聚氰胺打碎了全国消费者对食品安全的信心。突然间,饲料和养殖已不仅仅是一个行业,而成为了良心工程,质量、安全成为了一个行业,乃至国家和谐发展的基础。当然,我们不应该以一两家公司的做法来否定一个产业,但是我们必须承认的是各行各业对于产品质量都应该负起最起码的责任。在维生素行业,就有一个"对产品质量已经达到了苛求程度"的企业——兄弟科技股份有限公司。从2000年开始发展维生素K3项目,到如今成为国内甚至全球维生素K3老大,兄弟科技在维生素市场竞争日益激烈的今天,凭借着自身的优势在稳定维生素K3市场的同时,又展现出了在维生素B1领域的强劲发展势头。这一发展事实告诉我们,中国的维生素企业不仅能够在大品牌上做大做强(如维生素A和维生素E),在小品种(如维生素K3和维生素B1)上也一样能做大,并且在不久的将来逐渐做强。 相似文献

- In the case of pheasant chicks in particular it could be demonstrated that what is most commonly collectively termed degrees of “cannibalism”, picking of the back and wings, picking of the tail feathers, and picking of the cloaca (cannibalism in its restricted sense) are three, in the main, independent phenomena.
- At variance with results published by Sirén (1963a, b) no evidence was found in the experiments reported here that the amino acid arginine in any way influences the above mentioned phenomena. In fact, there was no evidence whatsoever indicating that nutritional factors play a rôle in any of the differences found.
- As far as the feather picking of back and wings (even to the degree that wounds were found) is concerned, behavioural factors are evidently active, since in sexed groups, the female batches picked significantly less than the male ones. The picking of tail and cloaca was not influenced by this measure. Back picking and tail feather picking did not influence the weight gain of the chicks, whereas picking of the cloaca, when occurring to any extent, significantly depressed weight gain.

Providing broilers diets formulated to a high amino acid density early in life improves subsequent growth performance and meat yield. Diets formulated to high amino acid concentrations beyond 5 wk of age may increase breast meat yield but may not be economically justified. This study examined growth, meat yield, and economic responses of broilers provided diets varying in amino acid density from 36 to 59 d of age. Birds were given a 4-phase feeding program: starter (1 to 17 d), grower (18 to 35 d), withdrawal-1 (WD1; 36 to 47 d), and withdrawal-2 (WD2; 48 to 59 d of age). All birds were fed a common, high amino acid density diet to 35 d of age (HH). Broilers were provided diets characterized as being high (H), moderate (M), or low (L) in amino acid density for the WD1 and WD2 periods. Dietary treatments were HHHH, HHHM, HHHL, HHMM, HHML, and HHLL from d 1 to 59, with H, M, and L representing the diets fed during each of the 4 periods (starter, grower, WD1 and WD2).Cumulative feed conversion was improved when the HHHH feeding regimen was fed, whereas other final live performance measurements were not affected. Decreasing amino acid density (HHLL and HHHL) limited yields of breast fillets, tenders, and total white meat when compared with the HHHH regimen. As amino acid density decreased from HHHH to HHHM, HHMM, and HHML, carcass yield and breast meat yield were not affected. In general, providing the HHHH feeding regimen increased economic gross feeding margin compared with the other dietary treatments. 相似文献

Integrated Resource Management-Standardized Performance Analysis (IRM-SPA) for fiscal yr 1995 was completed for 10 commercial cow-calf operations in southwestern Colorado. The ranches varied in size but operated in consistent production environments. Production and financial measures were examined and compared between operations. These included reproductive performance, weaning performance, and financial and economic costs for feed, grazing, and operating cost. Previous to a similar baseline analysis for fiscal yr 1994, the producers were not completely aware of the actual cost of production for their respective operations. The results of the analysis show that 7 out of the 10 operations had financial break-even values that were higher than the market price in the fall of 1995. Examples are provided for how a management tool like IRM-SPA can be used to identify critical control points for lowering costs in the cow-calf enterprise. IRM-SPA provides baseline data that can provide a starting point for monitoring progress of an individual operation, and it can serve a comparison with other operations within a region, production system, or the entire country, as shown in the presentation of these results. More importantly, it measures the cost per unit of production, which is an important variable that every cow-calf producer whose goals include continuing to participate in the beef production chain should know. 相似文献
