饲草饲料资源开发对青海省海东市经济发展的影响

畜牧产业是青海省海东市重要的传统产业,历来受到政府重视。饲草饲料资源开发对畜牧产业的发展提供重要支撑,但由于农民不了解,干部不重视等因素,影响饲草饲料资源开发及产业发展。随着现代化工业体系的建立,科学技术的发展,推动饲草饲料技术的发展。饲草饲料资源开发对地区农业资源循环利用、农民增收、经济发展的作用越来越凸显。饲草饲料资源开发是发展现代畜牧业的必然趋势,是拉动产业链条、调整农业结构、改善生态环境的需要,对地区经济发展有积极促进作用。青海省海东市在饲草饲料资源开发中仍存在一系列的问题,需要探索有效对策,促进海东市饲草饲料产业的发展和海东市的经济发展。 [关键词]饲草饲料|资源开发|青海省|海东市|经济发展     

成长型饲料企业人力资源面临的问题及解决策略研究

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     

低聚果糖与低聚半乳糖在婴幼儿配方乳粉中的精准化应用

母乳是婴幼儿营养配方的金标准,而低聚糖是母乳重要的活性成分。我国母乳喂养婴幼儿平均每天摄入3.5~6.4 g母乳低聚糖,而婴幼儿配方乳粉（以下简称“婴配粉”）喂养婴幼儿平均每天摄入的低聚果糖与低聚半乳糖仅0.6~3.0 g。为精准模拟母乳低聚糖的作用,低聚果糖与低聚半乳糖的含量至关重要。因此,低聚果糖与低聚半乳糖在婴配粉中的添加量有必要适当提高。     

低血糖生成指数液态奶的开发及测试

为获得营养均衡的调制牛奶,满足人体的多种营养需求,添加多种维生素和矿物质,设计出一款适用于糖尿病人、亚健康人群、体重管理、皮肤管理等人群饮用的低血糖生成指数（Glycemic Index,GI）的牛奶。稳定性试验结果表明,静置12 天后,牛奶无显著脂肪上浮,体系稳定性良好;人体GI值试验结果表明,调制牛奶的餐后血糖值上升和下降均较葡萄糖餐后血糖值平稳,有较好稳定餐后血糖的效果,表明开发的调制牛奶为低GI食品（GI值=22.86）。人体饱腹感试验结果显示,和普通纯牛奶对比,调制牛奶具有显著提高饱腹感的效果。     

宁夏回族自治区养殖粪污资源化利用现状调查与分析

畜禽粪污资源化利用,是农村生态环境保护工作的重点和难点,对于改善农村生态环境质量、提高农业绿色发展水平、促进农产品增产提质具有重要意义。本文为进一步了解宁夏回族自治区（简称“宁夏”）畜禽粪污资源化利用现状,在宁夏银川市、石嘴山市、吴忠市、中卫市、固原市5 市,对四大产业主导区畜禽养殖产业基本情况、全区及各市不同类型和规模的畜禽养殖粪污资源化利用现状及问题、不同养殖类型和规模的资源化主推技术及典型案例等情况进行了实地调研。结果表明：2020年,宁夏畜禽存栏总量2 046.0 万头（只）,其中,奶牛57.4 万头、肉牛120.7 万头、羊596.1 万只、生猪90.0 万头、家禽1 181.8 万只。畜禽粪污产生量3 025.3 万吨,全区粪污资源化利用总量为2 961.6 万吨,综合利用率达到97.9%,规模养殖场设施配套率达99.0%,该地区畜禽粪污综合利用主要途径有肥料化利用、能源化利用、清洁再生回用等。

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

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.     

Improved development of somatic cell cloned bovine embryos by a mammary gland epithelia cells in vitro model

Previous studies have established a bovine mammary gland epithelia cells in vitro model by the adenovirus-mediated telomerase (hTERT-bMGEs). The present study was conducted to confirm whether hTERT-bMGEs were effective target cells to improve the efficiency of transgenic expression and somatic cell nuclear transfer (SCNT). To accomplish this, a mammary-specific vector encoding human lysozyme and green fluorescent protein was used to verify the transgenic efficiency of hTERT-bMGEs, and untreated bovine mammary gland epithelial cells (bMGEs) were used as a control group. The results showed that the hTERT-bMGEs group had much higher transgenic efficiency and protein expression than the bMGEs group. Furthermore, the nontransgenic and transgenic hTERT-bMGEs were used as donor cells to evaluate the efficiency of SCNT. There were no significant differences in rates of cleavage or blastocysts or hatched blastocysts of cloned embryos from nontransgenic hTERT-bMGEs at passage 18 and 28 groups (82.8% vs. 81.9%, 28.6% vs. 24.8%, 58.6% vs. 55.3%, respectively) and the transgenic group (80.8%, 26.5% and 53.4%); however, they were significantly higher than the bMGEs group (71.2%, 12.8% and 14.8%), (p < 0.05). We confirmed that hTERT-bMGEs could serve as effective target cells for improving development of somatic cell cloned cattle embryos.     

Predicting Acceptability of Jaguars and Pumas in the Atlantic Forest,Brazil

Jaguars and pumas are threatened species in Brazil’s Atlantic Forest, especially at the borders of protected areas. This article assessed the influence of emotions, attitudes, existence value, and agency credibility on acceptability of big cats among rural residents living adjacent to two protected areas in this forest. Data from self-administrated questionnaires (n = 326) indicated those with positive attitudes toward big cats (β = .28, p < .001), those who valued the existence of big cats (β = .14, p < .05), those who would feel sorrow if big cats disappeared (β = .21, p < .001), and those who considered the managing agency as credible (β = .16, p = .002) were more accepting of big cats. The model provided theoretical and practical insights into large carnivore conservation. For example, given the significance of agency credibility, a positive relationship between park authorities and residents is crucial for big cat conservation.
