Comparative studies on two types of large East African zebu (Bos indicus) Boran cattle, on a beef ranch in Kenya, have indicated that a Boran type bred by the Orma tribe has a superior response to tsetse fly challenge. The Orma Boran when compared with an improved Boran was found to have lower trypanosome infection rates and, when untreated, better control of anaemia and decreased mortality.

Compared to France, Italy, the Netherlands and Germany the production of white veal in the United Kingdom is relatively limited. Nevertheless, public interest in veal calf welfare appears to be lively. Although calves are sucklings of social-living ruminants, veal calves are not allowed to suck, to have a social life or to ruminate. This, added to anaemia in order to obtain white meat, and the high rate of morbidity caused by high density of the animals, sums up the welfare problems which arise. In principle, there are two types of housing: single housing in crates or group housing. Group housing is almost impossible for calves younger than six weeks, because of disease control and urine sucking. Even after this age it requires much skill and labour. Enforceable regulations within the European Economic Community concerning the amount of light in the fattening houses and the measurements of crates for individual housing are suggested. It is recommended that anaemia in young calves should be treated.

A five-and-a-half weeks pregnant Airedale terrier with a genital haemorrhage was presented. It had a history of oestrous irregularities. It was found to be anaemic and Escherichia coli was isolated from vaginal swabs. Oestradiol and progesterone levels were normal. Two fetuses were aborted on day 41 of gestation. Antibiotic treatment was given. The haemorrhage ceased but on day 61 an abnormal vaginal discharge was seen. A caesarean operation was performed from which resulted three dead and two live fetuses, which died within two days. E coli was isolated from the uterine content, although the bitch was still receiving antibiotics; it was also still anaemic. It is probable that the haemorrhage was caused by an endotoxin produced by the E coli. The anaemia in the bitch did not improve the chances of fetal survival.

Full blood counts and fibrinogen estimations were carried out on 11 clinically normal, adult African grey parrots. Reference values derived from these tests were used to identify abnormalities in the blood counts of 11 sick parrots thought to be suffering from bacterial infections. All sick birds showed higher than normal heterophil counts, paralleled in some cases by lymphocytosis, monocytosis, thrombocytosis and increased fibrinogen levels. Anaemia was present in two birds and several others showed minor red cell abnormalities. The findings indicate that clinical haematology can make a useful contribution to the differential diagnosis of infection in African grey parrots. The findings also suggest that the development of anaemia can be a significant complicating factor in infectious conditions in these birds.

Blood dyscrasias developed after drug therapy in three dogs. Two died, one with pancytopenic marrow failure and the other with non-regenerative anaemia and thrombocytopenia. The third dog developed pancytopenia but recovered. An adverse reaction to phenylbutazone was suspected as the cause in each case, although two of the dogs had also received other drugs which sometimes cause blood dyscrasias in humans.

Quinuronium sulphate was inoculated into splenectomised calves at various times in relation to artificial infection of the calves with Babesia divergens. When the drug was given one day before the parasites it had no effect on the course of the infection. However, when it was given at the time of onset of fever or haemoglobinuria, development of the infection was arrested. Two weeks after therapy, recrudescences of parasites invariably occurred. In the case of animals treated at onset of fever these recrudescences were accompanied by increasing anaemia. Treated animals resisted subsequent challenge but remained as carriers of the parasite.

The use of trypanotolerant livestock is considered to be an important strategy for the control of African animal trypanosomiasis. In order to define the extent of the differences in susceptibility and productivity, 10 Zebu cows (a breed considered trypanosusceptible) and 10 N'Dama cows (a breed recognised for trypanotolerance) were exposed to a natural field challenge from Glossina morsitans submorsitans Newstead. The animals were two-and-a-half to three years old and had not been previously exposed to trypanosomiasis. All Zebu died of trypanosomiasis within eight months of first exposure. In contrast, only three N'Dama died of trypanosomiasis; they had all been suckling calves before they succumbed 11 to 14 months after initial exposure. The prevalence, level and duration of parasitaemia were significantly less in the N'Dama, which, unlike the Zebu, did not become febrile during parasitaemia. The differences in parasitaemia were largely attributable to Trypanosoma vivax. The N'Dama also developed much less severe anaemia than the Zebu. The mean and standard deviation of the packed red cell volume of the N'Dama was not significantly different between eight months after exposure when all Zebu were dead, and 21 months when the experiment was terminated. The relative productivity of the N'Dama was impressive. In addition to reduced mortality, the N'Dama experienced no abortions and produced five calves, three of which were alive at the end of the experiment, at which time three of the surviving N'Dama were pregnant. In the Zebu, in marked contrast, abortions occurred both in early and late pregnancy and no live calves were produced. The study confirmed that N'Dama cattle are innately less susceptible to trypanosomiasis than Zebu cattle and can survive and be productive in endemic areas of trypanosomiasis where Zebu perish.

Of 472 piglets (56 litters), half reeived 200 mg and half received 100 mg of iron as iron dextran administered intramuscularly as a single dose into the ham muscles between the first and fourth day after birth. The piglets were weaned at about three weeks of age, at which time those given 200 mg of iron had higher values of all haematological components. However, there was no significant difference between the mean daily live-weight gains of the two groups, and 100 mg iron maintained haematological components above levels associated with anaemia. It is suggested that 100 mg iron as iron dextran is adequate for piglets weaned at three weeks of age.

The pathology of Trypanosoma vivax (stock Y-486) in East African goats (Galla cross Masai) and Friesian cattle was studied sequentially. In both goats and cattle parasitaemia was detectable six to seven days after inoculation with 1 X 10(5) trypanosomes. The goats were more susceptible than cattle as indicated by higher parasitaemias, more severe anaemia and death in 25 per cent of the goats. The major pathological changes occurred in the lymph nodes, spleen, eyes, pituitary gland, testicles and heart. There was marked, generalised lymph node enlargement associated with an increase in the number and size of lymphocytic follicles accompanied by germinal centre formation. The medullary cords of the lymph nodes were distended and distorted by the high population of plasma cells. Similar changes were noted in the spleen. However there was no evidence for extramedullary erythropoiesis in both organs. Inflammatory changes were noted in the eyes, pituitary glands, testicles and heart.

The mean (+/- sd) packed cell volume (PCV) of the lambs in a flock mated by 'out-of-season' breeding methods and housed throughout the last six weeks of pregnancy and the whole of the suckling period declined to 23.3 +/- 3.34 per cent when the lambs were a month old, but recovered spontaneously to reach values within the normal range (30 to 35 per cent) before they were weaned at two months. Clinical signs of anaemia were observed in only a few lambs at three weeks old but the PCV values of all the lambs were significantly lower at this time than at weaning. There was no relationship between the PCV values during the two to four weeks after birth and the growth rate of the lambs. The administration of 200 mg iron, as iron dextran, by intramuscular injection to the newborn lambs prevented the decrease in PCV, but had no measurable effect on the health or growth rate of the lambs throughout the suckling period.
