成长型饲料企业人力资源面临的问题及解决策略研究     

雷松松 《中国饲料》2021,1(7):147-150

企业的发展通常要遵循企业的生命周期理论,从企业最初创立进入生存期,到企业规模进一步增大进入成长期,再到企业成熟期和衰退期,每个生命周期阶段的生产经营和管理策略都有所不同。当企业进入成长期,其发展潜力进一步释放,生产销售数据呈现快速增长的趋势,企业的管理形式也逐渐趋向成熟。对于成长型的企业而言,人力资源管理水平和现状关乎着企业的发展速度和水平,是企业未来的战略资源。而成长型的饲料企业相比于大型、集团化企业,存在人才吸引力低、人才流失严重、人力资源管理水平低等问题,这会影响饲料企业的转型升级。因此,本文以饲料企业为研究对象,基于当前我国成长型饲料企业的发展历程和企业特点,深入分析饲料企业人力资源面临的问题,并针对性地提出解决策略,破除饲料企业人力资源对企业发展的限制,帮助企业进一步健康发展。 [关键词] 成长型饲料企业|人力资源|问题|解决策略  相似文献

我国不同奶业产区规模化牧场饲料结构分析     

刘浩  董晓霞 《中国乳业》2021,(3)

在奶牛养殖规模化水平不断提高,养殖成本日益增加,且区域间差异明显的背景下,饲料作为奶牛养殖主要投入品,了解其在规模化牧场生产成本中的结构对于优化奶牛日粮结构、降低养殖成本、缩小区域间养殖效益差距等具有重要意义。本文利用2018—2020年规模牧场月度调研数据,分析了我国规模化牧场饲料结构情况。研究发现,大城市周边产区和南方产区的精饲料和粗饲料的比例相对更加科学,华北产区仍有较大提升空间,并且玉米、豆粕、玉米青贮和苜蓿草在日粮中占有较大比重,达到84.62%;不同产区奶牛日粮结构具有明显差距,玉米青贮和苜蓿草在西北产区占比最高,玉米和豆粕在南方产区占比最高。注重发挥区域优势,加大优质粗饲料和可替代饲料的利用,有利于降低养殖成本,提高养殖的科学性和可持续性。  相似文献   

餐厨废弃物饲料化技术及其在动物生产中的应用

餐厨废弃物(food waste,FW)的资源利用受到广泛关注。FW焚化、填埋、堆肥、厌氧消化等技术因其面临的环境可持续性问题而受到越来越多的批评。饲料化技术可以将FW转化为高价值的饲料,从而减少固体废物的排放、养殖成本和环境污染,但该技术应符合减少、再利用和回收有机废物的处理原则。作者综述了FW的饲料化技术及其在动物生产中的应用。FW饲料化技术主要包括热处理、酶处理、藻类培养、昆虫过腹、发酵技术。其中热处理可以确保微生物安全性,是其他技术的预处理技术。藻类培养和昆虫过腹技术可以将FW转化为植物和昆虫蛋白,避免同源污染,但尚不清楚藻类和昆虫在FW利用过程中是否会造成污染物积累。酶处理和发酵技术可以将FW中大分子转化为小分子。酶的催化性能和稳定性容易受外界条件的影响,需要考虑特殊的酶制剂。发酵技术的机械化程度和资源利用率高,其核心是微生物,需要筛选有效的、能充分利用FW的微生物。目前FW在畜牧业中的应用较少,在其生产和应用中要特别注意用量和使用时间。为了使FW饲料真正作为动物饲料进入食物链,研究人员必须对不同动物(含不同生长阶段)的生长性能和产品特性进行研究,以确保动物健康及动物产品对人类健康没有负面影响。  相似文献

Vachellia karroo leaf meal: a promising non-conventional feed resource for improving goat production in low-input farming systems of Southern Africa     

E Monday Idamokoro  Patrick J Masika 《African Journal of Range and Forage Science》2016,33(3):141-153

Among a vast number of forage trees, Vachellia karroo (Acacia karroo) remains one of the most widely distributed indigenous plant legumes in Southern Africa. The plant possesses some striking attributes, such as rapid growth rate, drought tolerance, adaptation to alkaline and acidic sterile soils, and resistance to a variety of edaphic and temperature changes. In past years V. karroo was recognised to be a major threat to rangeland productivity owing to its invasive nature. Research interest has shifted from its eradication as an unwanted plant to its utilisation as a feed resource for livestock. Extensive utilisation of V. karroo is mainly hindered by the presence of tannins and spines. Prospects to lessen the adverse effects of the anti-nutritional influences are now recognised. Vachellia karroo possesses desirable fatty acid profiles, and high protein and mineral contents that can improve animal performance. Presently, the use of V. karroo for goat production in communal areas is restricted owing to limited evidence for its nutritional value as animal feed. The present review, therefore, seeks to demonstrate the utility potential of V. karroo to improve growth performance, carcass characteristics, chevon quality, meat fatty acid profiles and as a natural anti-helminth for goats raised under an extensive system of production.  相似文献   

Formulation challenges of organic poultry diets with readily available ingredients and limited synthetic methionine     

《The Journal of Applied Poultry Research》2016,25(3):443-454

Organic agriculture has increased greatly over the past several years as consumer demand for these products has risen. Organic meat production, including poultry, has grown especially quickly, resulting in increasingly stringent guidelines being put in place to ensure safe, uniform, and ideal products for these consumers. Feed formulation and manufacturing for organic poultry in the United States are strictly regulated by the United States Department of Agriculture National Organic Program. Currently, no synthetic amino acids are allowed to be used in organic poultry diets in the United States except for limited quantities of synthetic methionine since it is typically considered the first or second limiting amino acid in corn and soybean meal based poultry diets and it is a critical nutrient for maintaining bird growth and productive performance, especially regarding egg size in laying hens. The aim of the review herein is to discuss the impacts that current organic regulations on synthetic methionine have on diet formulation when using readily available ingredients. High levels of crude protein must be used to meet bird methionine requirements with this restriction in place, which both increases feed costs and can have negative impacts on bird health and on air quality and the surrounding environment due to increased ammonia emissions. Atypical feed formulation strategies have been explored to address this issue, including such methods as feeding alternative ingredients and providing forage materials. Another possibility would be to use an average lifetime maximum inclusion rate for synthetic methionine, which may allow for better flexibility to provide sufficient methionine throughout various phases of growth and production since the requirements of the bird change with age.  相似文献   

Deoxynivalenol in chicken feed alters the vaccinal immune response and clinical biochemical serum parameters but not the intestinal and carcass characteristics          下载免费PDF全文

K. Ghareeb  W. A. Awad  Q. Zebeli  J. Böhm 《Journal of animal physiology and animal nutrition》2016,100(1):53-60

This study was conducted to investigate the impacts of deoxynivalenol (DON) feeding either alone or in combination with a microbial feed additive (MFA) on the immune response to a viral vaccine and serum clinical chemical parameters. Forty 1‐day‐old boiler chicks were weighed and randomly divided into four groups, 10 birds in each group: (i) control group fed with basal diet; (ii) DON group fed with basal diet artificially contaminated with 10 mg DON/kg feed; (iii) DON + MFA group fed with basal diet contaminated with 10 mg DON/kg feed and supplemented with 2.5 kg of MFA/ton feed; and (iv) MFA group fed with basal diet supplemented with 2.5 kg of MFA/ton feed. At 35 days of age, birds were slaughtered and blood was collected for investigating the antibody titre against infectious bronchitis virus (IBV) and clinical chemical parameters. The results showed that DON reduced (p = 0.032) the titre against IBV, decreased (p = 0.005) the level of alanine transaminase (ALT) (4.2 ± 0.5 U/l) compared with control birds (6.4 ± 0.5 U/l), increased (p = 0.002) the serum cholesterol concentration (144 ± 6 mg/dl) compared with their control counterparts (123 ± 5 mg/dl) and increased (p = 0.074) the amount of circulating triglycerides (62.25 ± 7.50 mg/dl) compared with controls (39.55 ± 4.74). These results indicate that dietary DON altered the humoral immune response to viral vaccine and affected the serum clinical biochemistry. However, DON in combination with MFA did not affect serum IBV titre. Taken together, DON in the feed of broilers produced an impairment of the success of IBV vaccine and affected the health of birds.  相似文献   

Effect of dietary probiotic,prebiotic and synbiotic supplementation on performance,immune responses,intestinal morphology and bacterial populations in broilers          下载免费PDF全文

This study was conducted to investigate the effects of probiotic (Primalac), prebiotic (TechnoMos) and synbiotic (Primalac + TechnoMos) supplementation on performance, immune responses, intestinal morphology and bacterial populations of ileum in broilers. A total of 240 one‐day‐old broiler chicks were randomly divided into four treatment groups which included 60 birds. Control group did not receive any treatment. The chicks in the second, third and fourth groups were fed probiotic (0.9 g/kg), prebiotic (0.9 g/kg) and probiotic (0.9 g/kg) plus probiotic (0.9 g/kg; synbiotic), respectively, at entire period. Daily feed intake, daily weight gain and feed conversion ratio were evaluated. The birds were immunized by sheep red blood cell (SRBC) on days 12 and 29 of age and serum antibody titres were measured on days 28, 35 and 42. Newcastle vaccines administered on days 9, 18 and 27 to chicks and blood samples were collected on day 42. Intestinal morphometric assessment and enumeration of intestinal bacterial populations were performed on day 42. The results indicated that consumption of probiotic, prebiotic and synbiotic had no significant effect on daily feed intake, daily body weight gain, feed conversion ratio, carcass traits, intestinal morphology and bacterial populations of ileum (p > 0.05). Consumption of prebiotic increased total and IgM anti‐SRBC titres on days 28 and 42 and antibody titre against Newcastle virus disease on day 42 (p < 0.05). Synbiotic increased only total anti‐SRBC on day 28 (p < 0.05). It is concluded that consumption of prebiotic increased humoral immunity in broilers. Therefore, supplementation of diet with prebiotic for improvement of humoral immune responses is superior to synbiotic supplementation.  相似文献
