Extract

The July 1973 issue of the New Zealand Journal of Agriculture discussed the Tama revolution. No mention was made of the possibility of nitrite poisoning in cattle grazing ‘Grasslands Tama’ (tetraploid westerwolds) ryegrass. There have been deaths from nitrite poisoning in cattle grazing Tama ryegrass and other crops in many districts this year, and this experience with a brief discussion on nitrite/nitrate poisoning is presented for the guidance of those who may be considering Tama ryegrass as a fodder crop.  相似文献   

The bacteriology and serology of ewes inoculated with viable Brucella ovis organisms

A series of 10 farm trials was conducted in which the lambing performance of ewes immunised against polyandroalbumin was compared with that of untreated ewes in the same flock. The trials show that polyandroalbumin treatment is a reliable method of increasing lambing and tailing percentages in New Zealand flocks. An average of 39 extra lambs born per 100 ewes tupped was achieved on farms where ewes were given two treatments about four weeks apart and rams were introduced 18–26 days after the second dose. On farms where rams were introduced less than 12 days after this booster injection an average of 19 extra lambs born per 100 ewes tupped resulted.

On farms where rams were introduced at 18–26 days post booster injection an average of 35 extra lambs were tailed for every 100 ewes tupped.

The response for immunization increased in direct relation to the liveweight of the ewes at tupping.  相似文献   

A study of the pattern of staphylococcal contamination of the udders of cows in a dairy herd

Abstract

Extract

The results of the 1965–6 New Zealand national mastitis survey (Anon., 1967 Anon Ann. Rep. Res. Div. N.Z. Dept. Agric. 1966–67 1967 77 78  [Google Scholar]) indicated that β-haemolytic staphylococci were the most common bacteria isolated from the milk of dairy cows. Effective control of β-haemolytic stapyhlococci on a national scaledepends ultimately upon an understanding of population changes of this organism within the cow and within the herd.  相似文献

Zinc sulphate was added to the drinking water of Angus cows and calves grazing an area considered marginal for copper nutrition of cattle. Mean daily intakes of approximately 12–15 mg Zn/kg live-weight further depressed already low plasma copper concentrations to levels considered to indicate copper deficiency. The plasma copper concentrations in untreated animals increased during the trial indicating adequate copper intakes during this period, but the high zinc intakes of treated animals prevented this seasonal rise. Injection of copper glycinate (0.24 g/animal) alleviated the depression of plasma copper associated with the high zinc intakes. The zinc supplements had little effect on plasma zinc concentrations.  相似文献

Serum samples collected from dogs routinely presented at a clinic between June 1974 and October 1980 were tested for the presence of haemagglutination inhibition (HI) titres to canine parvovirus. The first positive titre (> 1:320) was demonstrated in serum collected in October 1979. The first confirmed clinical case of canine parvovirus enteritis was diagnosed by the authors in July 1979.

In addition, between 1st December 1980 and 1st March 1981, serum samples were collected from 106 healthy dogs which were presented for canine parvovirus vaccination for the first time. Twenty-four dogs (approx. 23%) showed HI titres > 1:320 indicating probable previous canine parvovirus infection. Therefore approx. 80% of dogs in the clinic area were at risk at that time and vaccination should have protected them from infection.  相似文献   

Control of lice on cattle with dursban     

R.S. Buchanan M.Agr.Sc. Ph.D.  P.G. Coles Dip.Sheep 《New Zealand veterinary journal》2013,61(9):197-202

Extract

A number of spray formulations of organophosphorus insecticides that kill both nymphal and adult stages of lice on cattle are available to the farmer. To achieve high levels of control, two applications of these materials 14 to 17 days apart are recommended. The second application controls nymphs emerging from eggs already present at the first application and unaffected by it.  相似文献   

Post-parturient haemoglobinuria in cattle: A Heinz body haemolytic anaemia

Abstract

Extract

During the late summer and spring of the four years 1967 to 1970 many dairy herds throughout the Northland region? ? The Northland region is here regarded as that part of the North Island of New Zealand lying north of Auckland city. There are about 600,000 dairy cattle in this region. experienced outbreaks of a form of post-parturient haemoglobinuria. Clinically the disease was indistinguishable from that reported overseas. In 1970 the first cases occurred in mid-July and the incidence declined sharply towards the end of September, although in both 1969 and 1970 cases were still occurring towards the end of October. In some herds over 40% of the cows showed clinical evidence of the disease. Younger lactating cows, particularly 2- and 3-year-olds, were the more severely affected and most cases occurred 2 to 4 weeks post-partum. The most characteristic clinical feature of the disease was an anaemic state. Practising veterinarians reported that affected animals frequently showed haemoglobinuria, hyperpnoea, pyrexia, icterus, anorexia and decreased milk yield (either singly or in combination), and that occasional animals died with the disease. Intercurrent infectious disease (usually mastitis) was present in some of these fatal cases, while in others there was a history of forced exercise (usually droving with dogs) immediately prior to death.  相似文献

This subject will be covered in three sections, first, a brief history of how the idea of using trained dogs to help the blind was conceived, then the present-day methods of training guide dogs, and, finally, how the blind person is trained with their guide dog to work together as a team.  相似文献   

A note on the evaluation of tuberculin tests     

R. Jardine B.Agr.Sc. Dip.Math.Stats. 《New Zealand veterinary journal》2013,61(3)

Abstract

Extract

Sir,—Robertson (1963a Robertson, T. G. 1963a. N.Z. vet. J., 11: 6–6. [Taylor &; Francis Online] , [Google Scholar]), in discussing the evaluation of tuberculin tests, neither distinguishes between absolute and comparative evaluation nor recognizes that the evaluation of an ancillary test is merely a special case of comparative evaluation. The consequence of these shortcomings is his quite unwarranted conclusion (p. 8) that “the use of statistics based on the classification of slaughtered reactors only is of no value whatsoever in evaluating a test”. This statement is true only in the context of absolute evaluation.  相似文献
