生长育肥阶段与猪场的养殖经济效益有着直接的关系。虽然育肥阶段是整个生猪养殖过程中饲养难度最低,对环境的要求也不高的一个阶段,但是在实际的育肥过程中仍会出现育肥猪增重缓慢的现象,会严重影响生猪养殖的经济效益。引起育肥猪增重缓慢的因素是多方面的,包括仔猪质量的好坏、环境因素、饲养管理因素、饲料因素、疾病因素,以及中毒因素,要想提高育肥猪的增重速度,就需要分析育肥猪增重缓慢的主要原因。 相似文献

正冬季是育肥猪饲养的关键阶段。一般情况下,冬季的生猪出栏价格比较高,如果能够提升育肥猪的体重和猪肉品质,就能提升养殖企业的经济效益。但从整体来看,冬季育肥猪的饲养管理要求比较多,困难比较大,这就需要养殖人员提升育肥猪的管理能力。本文从多角度简要分析了冬季育肥猪的饲养管理技术。1选择合适的育肥猪品种冬季环境气温比较寒冷,对育肥猪的要求比较高。养殖 相似文献

规模化生产中,把保育期结束后用以商品化生产的猪称为生长育肥猪,其饲养管理是整个养猪生产过程中的一个重要阶段.饲养管理水平直接决定生长育肥猪的生产性能,从而影响养殖企业的经济效益.加强生长育肥猪的管理不仅能提高日增重和饲料转化率,还能在尽可能短的时间内生产出大量优质猪肉.文章针对实际生产中现代规模化猪场如何做好生长育肥猪的饲养管理作综合阐述. 相似文献

近年来,随着猪肉需求量的不断增大,我国生猪养殖产业得到了快速的发展。散养是我国普遍存在的一种生猪饲养方式,与集约化以及规模化养殖相比,散养猪需要较长的生长周期,其养殖密度较小,同时生猪运动量较多,因而猪肉口感更佳。但是在实际的饲养过程中,由于缺乏专业的养殖技术,饲养管理较为粗放,导致生猪疫病问题较多,因而必须要制定一个切实可行的疫病防控措施,使散养猪管理工作具备更高的安全性以及可靠性,进而帮助养殖户获取更高的经济效益。 相似文献

育肥猪肠道疾病问题是当前规模化猪场最常见的问题之一,其病因复杂导致防控难度增加,常见发病原因分为病原性因素与非病原性因素两种。病原性因素如病毒、细菌、寄生虫等;非病原性因素如生产管理、饲料营养、应激等外部环境引起。在我国当前的养殖环境下,病原性因素引起的猪肠道疾病占据大多数,常见的导致育肥猪腹泻的疾病的病原微生物如细胞内劳森菌(引起猪回肠炎)、猪密螺旋体痢疾、大肠杆菌、沙门氏菌、寄生虫及部分病毒性疾病等的感染在我国的猪场广泛存在,这些病原微生物会导致育肥猪群发生急性或慢性消耗性腹泻,使育肥猪发生成活率降低、饲料报酬下降、生长速度减缓、僵猪和残次猪比例升高等情况,给生长育肥猪的正常生长和出栏造成了很大的危害。文章通过对育肥猪肠道疾病的发病原因、发病特点与危害以及防控等方面进行了简要的阐述,以供参考。 相似文献

非洲猪瘟疫情对中国生猪产业可能产生巨大且长期的影响。一方面因为生猪饲养量大幅度减少,造成供给不足;另一方面,尽管猪肉消费在短期受到了一定程度的抑制,但由于消费偏好无法短期内改变,猪肉“刚需”仍然存在。预计2019年中国猪肉供需缺口将在1000万t左右,全年猪价将呈现“先抑后扬”态势,生猪价格将可能在近两年内都处在较高水平。猪价上升可能通过产业链波及至食品全行业,导致物价水平整体上涨。建议加大生猪生产扶持力度,调动生猪养殖积极性;明确政府管理权责,确保猪肉稳定供应;遵从产消对接、区域互补原则,以农牧结合为前提,构建生猪生产消费均衡区域布局。 相似文献

随着养殖水平不断提高以及居民对猪肉制品消费和需求的不断增加,我国生猪养殖规模的不断扩大,目前生猪存栏量、出栏量均较前期有所提高。我国养猪业在不断发展的同时,也在面临着前所未有的困难和挑战,其中对养猪业和养殖者来说最大的难题,就是猪病的种类不断增加,以及随之不断提升的预防和治疗的难度与成本。特别是对于生长育肥猪来说,一旦患病,便会给养殖者带来巨大的经济损失。文章对目前生猪养殖业中生长育肥猪常见且危害较大的几种疾病的临床表现和防控进行了简要综述。 相似文献

养殖环境对生猪的健康生长有至关重要的影响,会严重威胁不同年龄和不同猪的健康生长和繁殖。生猪养殖中如果不能严格控制养殖环境,易造成种公猪的精液质量下降,精子活性降低,母猪不能正常发情,隐性发情。不规律发情,影响母猪正常排卵,使繁殖率显著下降。对于养殖场的育肥猪养殖环境还会影响整体的育肥效果,使饲料的成本显著增加,不利于提高养殖效益。因此在发展生猪养殖中,注重做好养殖环境的控制,减少各种污染物的产生,确保生猪健康生长。该文主要论述养殖环境对不同年龄阶段猪的影响,并提出养殖环境的改善措施。 相似文献

This experiment was conducted to investigate the effect of fermented peanut shell on production performance, carcass traits, meat quality and economic benefits of fattening pigs.100 fattening pigs (Duroc×Landrace×Yorkshire) with an average weight of 50 kg were randomly divided into 5 groups with 4 replicates per group and 5 pigs per replicate.The control group was fed with corn-concentrates-based feed, groups 1 to 4 were fed with the basal diets supplemented with 10% fermented peanut shell, 20% fermented peanut shell, 30% fermented peanut shell and 15% fermentation of corn stalk, respectively.The trial lasted for 66 days.The results showed that ADFI in control group, group 2 and group 3 were significantly higher than that in group 1 and group 4 (P<0.05), ADG in control group and group 3 were significantly higher than that in group 1 and group 4 (P<0.05), there was no significant difference in F/G among all groups (P>0.05).Diarrhea frequencies in groups 1 to 4 were extremely significantly lower than that in control group (P<0.01).There were no significant differences in carcass quality, slaughter rate, backfat thickness and eye muscle area among all groups (P>0.05), lean meat percentage in group 2 was significantly lower than that in control group and group 1 (P<0.05).There were no significant differences in marbling, meat color, tenderness, intramuscular fat, water loss and cooked meat percentage among all groups (P>0.05), water losses in groups 1 to 4 were lower than that in control group, but the differences were not significant (P>0.05).According to the economic benefit analysis showed that in pig from 50 to 90 kg, average profit of each pig in control group was 47.60 yuan, average profits of each pig in groups 1 to 4 were respectively 56.40, 60.40, 78.80 and 58.80 yuan, while group 3 was optimal.Based on the analysis of the above result, the fermented peanut shell had no bad effect on growth performance, carcass traits and meat quality of pigs, and it could effectively reduce the diarrhea frequency of pigs, improve the system of hydraulic of pork, when the fermented peanut shells were appropriatly applied in pigs feed, which could effectively reduce the breeding cost, and improve the economic benefit. 相似文献

The present study investigated risk factors for mortality in grow-finishing pigs of 137 pig herds belonging to one integration company during a period of 2.5 years. Mortality data, expressed as the number of dead pigs divided by the number of pigs placed in the fattening unit were investigated retrospectively. The following potential risk factors were evaluated: type of pig herd, season and year of placement in the fattening unit, pig density in the municipality, management practices (density of the pigs in the barn, origin of the pigs), housing conditions and feeding practices. The overall average mortality percentage was 4.70%. Three variables in a multivariable regression model were significantly associated with mortality: season of placement in the fattening unit, origin of the piglets and duration of the fattening period. Pigs placed in October, November and December, were at higher risk than pigs placed in other months. Herds that purchased pigs from a merchant, used pigs from other herds with an excess of piglets for filling their fattening units or herds that purchased pigs from more than five origin herds also suffered higher mortality. The mortality also increased in case of longer duration of the fattening period. This study documented for the first time that in addition to seasonal effects and a longer duration of the fattening period, purchasing feeder pigs from one or a limited number of herds is of crucial importance to achieve low mortality in the grow-finishing pigs. 相似文献
