Epitheliogenesis imperfecta (EI) has been diagnosed in calves on a north Queensland beef cattle research station. There are five Bos indicus cross, inter se mated breed groups on the station: 1/2 Brahman, 3/4 Brahman, 1/2 Sahiwal, 3/4 Sahiwal and High Grade Sahiwal. The disease was confined to the three Sahiwal breed groups and caused calf losses over seven years from 1978 of 0.2%, 3.4% and 1.0% in the 1/2, 3/4 and High Grade groups respectively. The Sahiwal breed was identified as the origin of the gene responsible for the disease. The source of the gene within the Sahiwal breed was investigated, and several ancestors were identified as almost certainly being heterozygotes. Analyses of relationships of affected and non-affected calves to the 10 Sahiwals that were originally imported into Australia identified the one that was most likely the source of the El gene.

AbstractThe aim of this study was to rank diverse beef cattle genotypes for meat quality characteristics and to determine whether that ranking changed depending on the environment in which the animals were finished. Breed groups, ranging from 100% Bos indicus to 100% Bos taurus content, were derived from Indian zebu (Brahman), African zebu (Boran), British breeds (Hereford-Shorthorn), continental breeds (Charolais and Simmental) and Sanga (Tuli and Belmont Red). Heavy steers (>600 kg) were raised in a tropical environment and finished either on pasture or in a feedlot.For striploins (longissimus) from feedlot finished steers, cooking loss was greatest for zebu (Z) steaks, least for British (B) steaks (P < 0·001), and intermediate for the other breeds. For striploins from pasture finished steers and eye rounds (semitendinosus) from both pasture finished and feedlot finished steers, there were no breed differences in cooking loss.For both feedlot finished and pasture finished steers, striploin steaks from B steers were most tender, and Sanga (S) and zebu × continental cross (ZC) steaks were more tender than Z steaks. Warner-Bratzler initial yields suggested that the lower toughness of these breeds was due to lower myofibrillar toughness. Peak force minus initial yield suggested a smaller, opposite effect of increasing connective tissue toughness associated with increasing Bos taurus content. This breed effect on connective tissue toughness was more prominent in the eye round samples. In the feedlot finished steers, Z eye round was as tender as B eye round. In pasture finished steers, Z eye round had a peak force 1·3 kg lower than B in contrast to the results for striploin where Z was 1·2 kg higher than B. Sanga eye round followed the same trend as B relative to Z but to a lesser extent. From the feedlot, S eye round was more tender than Z eye round and from pasture, S eye round was the same as Z eye round. There was no evidence of heterosis f or any meat quality attribute.These results are best explained in terms of a model incorporating differential effects of breed on the myofibrillar and connective tissue components of toughness. The implications of this study are that the tenderness of grilling and roasting cuts of meat from the predominantly Brahman-based beef herd of northern Australia can be improved through crossbreeding with any of the taurine breeds studied.

Reproductive Rates

A breeding program was established at Swan's Lagoon Beef Cattle Research Station in the dry tropics of northern Queensland to evaluate the productivity of cattle which were genotypically at least one-half Bos indicus. Brahman or Sahiwal bulls were initially mated to B. taurus cows (predominantly Shorthorn) to produce the first filial generation (F1 1/2 Brahman and F1 1/2 Sahiwal). First backcross 314 Brahman and first backcross 314 Sahiwal were derived from crossing F1 1/2 Brahman or F1 1/2 Sahiwal cows to their respective sire breeds. This paper reports on the female reproductive rates and liveweight performance in 2 data sets: 1972-79, F1 1/2 Brahman v. F1 1/2 Sahiwal; 1975-83, first backcross 3/4 Brahman v. first backcross 3/4 Sahiwal. In both data sets, significant differences in fertility (pregnancy rate and calving date) between F1 or first backcross groups were infrequent, and where differences did occur, they were often inconsistent due to cross x year interactions. The difference between weaning rates and pregnancy rates (representing foetal and calf wastage) was 5 percentage units higher in Sahiwal crosses than Brahman crosses for lactating cows Year effects significantly (P<0.05) influencd both fertility and liveweight, demonstrating the extent of seasonal influences on cattle production in the dry tropics. Generally Brahman-cross cows were heavier throughout than their Sahiwal counterparts. Among lactating cows, F1 1/2 Brahman were 21 kg heavier at start of mating than F1 1/2 Sahiwal, while first backcross 3/4 Brahman were 29 kg heavier than first backcross 3/4 Sahiwal.

Massey University assumed management responsibility for "Riverside", a 723 ha sheep and beef cattle farm 8 km north of Masterton in Master-ton in March 1978. The farm is leased to the University under the terms of the will of the late Mr Sydney Campbell to assist in the accumulation, expansion and dissemination of knowledge about agriculture, with particular emphasis on agriculture in the Wairarapa. A lo-year farm development programme instigated in 1978 resulted in the sale of the beef herd and the winter stocking rate of sheep being increased to 15.1 suiha by 1984 (9.7 sulha in 1978). In 1985 stocking rates were sharply reduced following a severe drought and the current mixed 2-year bull beef and breeding ewe policy was introduced. Recent research has focused on drought-tolerant pasture species. In late 1992 sheep and beef cattle farmers (n=lOO) were surveyed to identify local information needs and how Riverside could continue to serve the region's research and extension requirements. Information related to fertilisers and farm management were most frequently rated as the most imporant current needs. Keywords: extension, research, Riverside, teaching, Wairarapa

Background: The linear type traits are the one of important tools for selection of milch cattle. The lifespan of cattle mostly depends on these linear type traits particularly feet and udder related traits. So it is necessary to measure the linear type traits and effect on longevity of Sahiwal cattle. Methods: The experiment was conducted on 86 Sahiwal cattle maintained in Bull mother experimental farm and government cattle breeding farm, Anjora, Durg (C.G.). The linear type traits in Sahiwal cattle were measured as per the recommendation of International committee for animal recording (ICAR). Result: The different linear type traits were studied the average value of stature 125.39±0.534, Chest width 27±0.49, rump angle 12.75±0.97, rump width 17.32±0.29, rear leg set (side view) 146.03°±0.91, rear leg set (rear view) -3.74±0.15, udder depth 18.97±0.43, udder cleft 2.77±0.95, rear udder height 24.06±0.45, fore udder attachment 130.50±1.75° and front teat position 3.61±0.13 cm. these linear type traits mainly affects the longevity and survivability of Sahiwal herds. The most of the traits were found to be intermediate type it leads to increase the longevity and fewer reproductive problems in the Sahiwal herds.

Objective: Haematuria may be transient for a number of benign conditions, particularly a urinary-tract infection (UTI). We set out to determine if a negative repeat urinalysis at the time of urological assessment for patients with haematuria could predict negative investigations and whether investigations could be tailored by this test. Methods: This was a retrospective analysis of records for all patients attending a haematuria clinic between 16 September 2013 and 12 September 2014. This included patients with visible and non-visible (microscopic) haematuria. Results: There were 1138 patients, 599 with visible haematuria (VH) and 460 with non-visible haematuria (NVH). Seventy-two patients were excluded. A total of 546 patients had a positive repeat urinalysis for blood; 438 patients had a negative repeat urinalysis when tested at the haematuria clinic, 298/599 for VH and 140/460 NVH. For those who had negative repeat urinalysis, urothelial cancer was found in 15/298 VH and 1/140 NVH. The one patient with negative repeat urinalysis and NVH was found to have a grade 2 (high grade) bladder tumour. The negative predictive value for a negative repeat urinalysis in transient haematuria was 0.95 for VH and 0.99 for NVH. Twenty-nine patients with VH and repeat negative urinalysis on assessment had a positive urine culture suggesting a UTI as a cause. None of these patients was found to have urothelial cancer ( p = 0.0413). Conclusion: Patients who experience transient VH and subsequent repeat negative urinalysis in the absence of infection have a 5% chance of urothelial cancer and should still be investigated. For those with transient NVH, the probability of finding a urothelial cancer is <1%, although we did find a high-grade bladder tumour in this group. If patients have a positive urine culture and a negative repeat urinalysis following treatment, they could be spared haematuria investigations.

Analysis Of Performance

The need to speed up the rate of genetic progress in beef cattle, particularly in economically significant traits such as growth and carcase merit has always been recognised by the Meat and Livestock Commission. This is achieved through the Beefbreeder Pedigree Recording Service which records over 1,000 pedigree herds in Great Britain. Traditionally, analysis of performance records from pedigree herds has been carried out using within herd contemporary comparisons.Average pedigree beef herd size in Great Britain is typically less than 20 cows which limits accuracy and scope for genetic improvement when making within herd selection decisions.

In June 1980, 190 Kimberley Shorthorn steers from five properties in the Kimberley were divided into three age categories. Half were sent to Chapman Research Station (CRS) in the agricultural area of Western Australia and the remainder stayed at Ord Regeneration Research Station (ORRS) in the Kimberley. Animals in both locations grazed for either one or two pasture growing seasons and a third group was fed a concentrate ration based on grain after the first growing season. Cattle lost between 20-30 kg in handling and transport south which, together with the reduced initial grazing season, led to gains of only 50 kg while those in the north gained around 100 kg. In the second grazing season at both locations animals gained around 140 kg. Animals at ORRS laid down more fat than those at CRS. Animals fed on concentrate rations in the agricultural area grew significantly faster, but had poorer food conversion and were leaner compared with those fed in the Kimberley.
