串叶松香草饲喂特种野猪试验

许美解等在湖南衡阳地区试验，特种野猪每组10头，19～20千克开始试验，饲养150天，对照组全精料，试验组加10％、20％、30％鲜串叶松香草代替部分精料（以6千克鲜草代替1千克精料）。结果，以加20％串叶松香草组效果最好，与对照组比，日增重提高9．9克，每头猪节省精料28．6千克，头毛利增加88．71元。     

提高奶牛生产成绩的措施

1提高奶牛产乳量 脲酶抑制剂型奶牛预混料的应用。研究发现脲酶抑制剂型奶牛预混料的添加量为25×10-6。据报道，1995年在黑龙江省用503头牛做试验，试验组产奶量每头每天均20.1千克，对照组为17.47千克，增幅为15.05%，每产1千克奶试验组少用了69克精料。其中，牛乳中的乳蛋白含量和乳脂率都有所提高。据报道，1998年6月5日至8月5日在上海浦东唐镇奶牛场进行喂用脲酶抑制剂预混料的试验，试验组与对照组各选10头奶牛，饲喂结果表明试验组每头多产标准乳2.96千克/天，乳脂率增加0.29%，每产1千克奶，少用干物质9%，增产牛奶16.1%。     

芦苇是喂奶牛的优质粗料

1 试验方法选泌乳中后期的健康黑白花奶牛6头,按年龄、胎次、体重、泌乳月、产奶量、乳脂率等相近的原则分为两组,每组3头。按黑龙江省黑白花奶牛饲养标准配制日粮。对照组青贮玉米8千克,干草13千克,食盐0.15千克;试验组青贮芦苇8千克,干草13千克,食盐0.15千克。两组混合精料均为6.5千克(其中蛋白质饲料占34％),矿物质添加0.15千克。 1992年11月8日～12月8日为正式试验期。严格按照设计要求单槽定量喂饲,自由饮水和运动,每日早、午、晚三次挤乳。 2 试验结果     

青绿饲料替代部分精料饲喂奶牛试验

利用５０头泌乳母牛进行了为期４５天的青绿饲料替代部分精料的饲喂试验。结果表明，２０千克黑麦草替代２０％左右的精料既不影响产奶量和乳脂率，而且可降低饲料成本５０６％，提高经济效益９６９％。     

奶牛增乳预混料应用试验

我们于１９９７年１２月２６日至１９９８年３月１５日在山西省畜牧兽医研究所奶牛场对山西省饲料监察所研制的奶牛增乳预混料进行了为期８０天的试验。试验采用单因子重复交叉设计。试验结果表明：应用奶牛增乳预混料，头日平均产奶量比对照组增加０８３千克，提高５％，乳脂率提高０２个百分点，每产１千克奶消耗精料０４８千克，比对照组减少００４千克，降低７７％。整个试验期，奶牛头日产奶收入比对照组增加１４９元，头日饲料成本比对照组减少０１６元，两项合计，头日效益比对照组增加１６５元。     

加酶高粱青贮对奶牛产奶量的影响

本试验选择36头黑白花奶牛，按胎次、泌乳月、日产奶量基本一致进行逐头配对，分为试验组和对照组。试验组的牛每天饲喂20千克酶制剂处理的全株高粱青贮，对照组每天饲喂20千克全株玉米青贮藏，干草及混合精料成分和饲养量完全一致。试验期为34天。结果显示：试验组奶年日平均产奶量比对照组高2.72千克，平均日产奶量增加10.19%，极显著高于对照组奶牛日平均产奶量（p=0.0074）。说明用酶制剂处理可以显著改善青贮饲料的营养价值。     

养母猪致富快

我家饲喂一头母猪,1988年1月18日产小猪11头,3月20日出售最大的28.6千克,最小的24千克,平均每头25.5千克,全窝重28.05千克,以每千克5.40元售出,总收入1514.7元,除去饲料、医药等开支,获纯利1164.7元。6月5日母猪又产小猪13头。我觉得养母猪致富快。母猪从受胎到分娩一般要113天左右,在这期间应分三个阶段来喂养,即:受胎后的第一个月日粮中要多加一些精料,如豆饼之类,喂量可依母猪的膘情而定。第二个月酌情减少一些精料,多加一些蔬菜之类。最后一个阶段,也就是临产的前一个时期,多加一些精料,贝     

肉牛育肥的经济效益

江西省畜牧技术推广站娄佑武等以粗饲料为主,对42头平均18月龄的杂种公牛进行育肥试验.他们把稻草、花生藤铡短为2～3厘米,稻草用4%尿素氨化,花生藤在饲喂前1%氯化钠液浸泡8～12小时.采用日粮为稻草1千克,花生藤4千克,谷酒糟4千克,豆渣0.5千克,精料(玉米50%、麦麸20%、菜粕12%、棉粕12%、盐2%、预混料4%)1.94千克. 试验开始与结束各称重1次,每次8:00开始空腹称重,记录每头牛体重和采食量,结果试验牛平均日增重为1.08千克,料(精)重比平均为1.80.按肉牛毛重实际售价7.38元/千克计算,稻草、花生藤、酒糟、豆渣、精料每千克价格分别为0.24元、0.26元、0.05元、0.14元和1.32元,81天试验期内每头牛日盈利平均为3.01元.     

苜蓿是饲喂奶牛的好饲料

苜蓿是一种营养价值高的优质豆科牧草,粗蛋白含量是羊草的 2.3倍,可消化粗蛋白含量是羊草的 3.2倍,接近混合精料。按北京市市场价,苜蓿、羊草、混合精料 100克可消化粗蛋白价格分别为 0.89、 1.71、 0.88元 (100∶ 192∶ 99)(见表 1) 　　本次饲用苜蓿、羊草的粗蛋白含量分别为 16.5％和 6.3％。 　　头日用 2.5千克苜蓿取代 2.5千克羊草作了试验,试验牛群 120头,对照牛群 100头,其他日粮及饲养管理条件完全相同 (见表 2)。 　　试前泌乳月、产奶量按相近原则采用配对法在试验、对照牛群中各选 47头进行产奶量及乳成分观察。产奶量试…     

生物活性制济对肉牛增重效果的试验分析

Complications and survival associated with surgical compared with medical management of horses with duodenitis-proximal jejunitis

REASONS FOR PERFORMING STUDY: Based on clinical observation, it is hypothesised that horses with duodenitis-proximal jejunitis (DPJ) that are treated surgically have a shorter duration, smaller volume, and slower rate of nasogastric reflux (NGR) compared to horses treated medically, are more likely to develop diarrhoea than medically managed cases, and have a higher incisional infection rate than a sample population of horses undergoing abdominal exploration for gastrointestinal disease other than DPJ. OBJECTIVES: To compare: 1) duration, volume and rate of NGR and the percentage of horses with diarrhoea between medically and surgically treated DPJ cases; and 2) incisional infection rate in horses with DPJ undergoing abdominal exploration to a sample population of horses undergoing abdominal exploration for gastrointestinal disease other than DPJ. METHODS: Medical records of cases with DPJ diagnosed 1995-2006 were reviewed. Information obtained included subject details, presenting clinical findings, treatment category (medical/surgical), complications (diarrhoea, incisional infection), and outcome (survival/nonsurvival). Data were analysed using a Chi-squared test and a mixed model analysis of variance. Level of significance was P<0.05. RESULTS: Compared to medical cases, surgical cases had significantly decreased survival, a longer duration and larger total volume of NGR, and were more likely to develop diarrhoea. The incisional infection rate for horses with DPJ undergoing abdominal exploration was 16% compared to 7% for the sample population of horses. CONCLUSIONS: Surgical treatment of horses with DPJ did not lead to resolution of NGR faster than medical treatment. Surgical cases were more likely to develop diarrhoea and did not have a significantly higher incisional infection rate than the sample population.     

Serum triglyceride concentration in dogs with epilepsy treated with phenobarbital or with phenobarbital and bromide

OBJECTIVE: To compare serum triglyceride concentrations obtained after food had been withheld (i.e., fasting concentrations) in dogs with epilepsy that had been treated long term (> or = 3 months) with phenobarbital or with phenobarbital and potassium bromide with concentrations in healthy control dogs. DESIGN: Cross-sectional study. ANIMALS: 57 epileptic dogs that had been treated with phenobarbital (n=28) or with phenobarbital and bromide (29) and 57 healthy, untreated control dogs matched on the basis of age, breed, sex, neuter status, and body condition score. PROCEDURES: Blood samples were collected after food had been withheld for at least 12 hours, and serum biochemical and lipid concentrations were determined. Oral fat tolerance tests were performed in 15 control dogs and 9 dogs with epilepsy treated with phenobarbital alone. RESULTS: 19 of the 57 (33%) epileptic dogs had fasting serum triglyceride concentrations greater than the upper reference limit. Nine (16%) dogs had a history of pancreatitis, and 5 of the 9 had high fasting serum triglyceride concentrations at the time of the study. A significant relationship was found between body condition score and fasting serum triglyceride concentration in all dogs, but serum triglyceride concentration was not significantly associated with phenobarbital dosage or serum phenobarbital concentration. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that dogs treated long term with phenobarbital or with phenobarbital and bromide may develop hypertriglyceridemia. Fasting serum triglyceride concentration should be periodically monitored in dogs treated with phenobarbital because hypertriglyceridemia is a risk factor for pancreatitis.

Long-term treatment with carprofen of 805 dogs with osteoarthritis

The pain-relieving effect of carprofen and tolerance to the drug were investigated in 805 dogs that were lame as a result of osteoarthritis. The dogs were of different breeds, ages and bodyweights and of both sexes, and were selected from 51 veterinary clinics. Each dog was treated orally by its owner with 4 mg/kg carprofen for 84 consecutive days. Twenty-four dogs were removed from the study because of side effects, and 55 left the study for reasons unrelated to the treatment. The condition of the dogs and the benefit of the treatment were evaluated by the veterinary surgeons and the owners after 14 days, and at the end of the period of treatment, when 194 of the dogs (26.7 per cent) were no longer lame, and 357 (49.2 per cent) had improved. The period for which the dogs had been lame before entering the study significantly (P<0.01) affected the results and the rate of improvement. Too much exercise during the 84 days of treatment caused some dogs to relapse.     

Prognostic factors associated with survival in dogs with lymphocytic-plasmacytic enteritis

Prognostic factors associated with survival in dogs with lymphocytic-plasmacytic enteritis (LPE) were investigated through a retrospective study. Using case records, 48 dogs diagnosed with LPE were classified as survivors (n = 32) or non-survivors (n = 16), and the clinical and clinicopathological parameters were reviewed between the 2 groups by using univariate and multivariate prognostic analysis. Compared to the hospital population, non-survivors had an overrepresentation of the Shiba breed. Results of univariate analysis indicated that anorexia, severe weight loss, packed cell volume, and total protein were significantly associated with survival for 6 months after diagnosis. In multivariate analysis, anorexia and hypoproteinemia were significantly associated with survival. Furthermore, initial response to treatment was strongly associated with poor prognosis. Based on these clinical and laboratory parameters such as anorexia, hypoproteinemia and initial response to treatment, it may be possible to predict poor prognosis in canine LPE.
