Abstract:
AbstractThe Longhorn cattle breed has a long and prestigious history, dating back prior to the livestock pioneers of the 18th century. It was, for a period, the improved breed of choice in the Midland Counties. But the breed gradually fell from favour and, by the early 1970s, only 6 significant Longhorn herds remained in the UK. However, the Longhorn was one of many rare breeds to benefit from the growth of the rare breeds movement in the 1970s, led by the Rare Breeds Survival Trust. A number of factors have helped the breed to recover, including: an active breed society providing registrations and analyses based on these, promoting the breed, organising sales and shows and providing an important social framework for breeders and supporters; creation of a semen bank; niche marketing of meat and hides and the use of the breed in conservation grazing.

Walter Shandy’s fecundity is called into question in several chapters of Tristram Shandy, and so is the ability of his bull. This note draws a socio-historical connection between Walter’s and the bull’s fertility and a common cattle breed likely known by Sterne.

Abstract:
Congenital ocular disease occurs uncommonly in cattle, with multiple abnormalities reported only sporadically in the literature. This report describes a case of anterior segment dysgenesis resulting in glaucoma in a 4-month-old Texas Longhorn steer. On clinical exam, bilateral buphthalmia was present and intraocular pressures exceeded 47 mm Hg in both eyes. On histopathologic examination, the iridocorneal angle and filtration apparatus were distorted due to collapse of the ciliary cleft and anterior displacement of the anterior portion of the ciliary body. No evidence of inflammation or other causes of glaucoma were recognized.

Abstract:
Our objective was to describe key phenotypic characteristics of a population of Rarámuri Criollo (RC) cattle introduced from the Copper Canyon of Chihuahua, México into the Southwestern United States almost two decades ago. We recorded 26 phenotypic traits of 37 RC individuals including mature cows, first-calf heifers, and mature bulls raised at the USDA-ARS Jornada Experimental Range in southern New Mexico. This herd of RC cattle exhibited intermediate body sizes compared to the smaller Corriente and larger Texas Longhorn and Florida Cracker cattle. Coat colors were similar to those described for other Criollo biotypes but horn shape and size of RC appear to be different than that of other US-based Criollo breeds. Though smaller than commercial beef breeds, RC cattle appear to be well-matched to the Southwestern US environments as evidenced by previous studies that evaluated their grazing behavior, weight gains, and carcass quality. Rarámuri Criollo cattle are a genetic resource whose conservation could be critically important for climate change adaptation of ranches in the desert Southwest.

Abstract:
SummaryCharacteristics of lactation performance, based on AM milk offtake and conformation, of Ankole cattle were studied during one year in 37 herds with 606 recorded cows in Mbarara district in southwestern Uganda. Recording of AM milk offtake was undertaken in eight areas of Mbarara district which represent different production systems and vegetation types.The 467 cows with complete lactation cows yielded, on average, a total AM offtake of 252 and 325 kg over first and second or higher lactations, respectively. These offtakes were higher than other African indigenous populations in pastoral systems. Mean body weight was 292 and 341 kg for first and second or higher parities, respectively. Average body measurements for all parities were 161 cm for heart girth, 129 cm for height at withers and 193 cm for body length.The daily AM milk offtake varied from 1.1 kg in the Ruhengere area characterized by thorny Acacia thickets to 1.9 kg in the bush-cleared Kanyanya area with improved pastures. Although the Ankole cows performed best on the improved pastures, their future may relatively be more favourable in the original non-cleared bush areas because of the gradually increasing competition from exotic dairy breeds and their crosses.

Abstract:
Summary Gene frequencies of rbc antigens were determined in Holsteins and Colombian (criollas) cattle living at 3,000 m, and in cattle descended from fighting bulls (Vacas de lidia) living at 2,500 m. These frequencies were compared with those of Holsteins, cattle native to Florida (scrub cattle), longhorns, and native cattle from Brazil (caracu cattle) living at sea level. The criollas, Vacas de lidia, scrub cows, longhorns, and caracu are descendants of original Iberian stock introduced to the Americas. We found that despite common ancestry (scrub cattle, longhorns, criollas, and caracu), genetic differences may have been derived through years of demographic isolation. The most remarkable blood-group differences were found in the high prevalence of the B system phenogroup (heritable group of antigenic factors) BQA'G'34 in the Vacas de lidia, and of the S system phenogroup U1H' in these cattle and in caracu. Furthermore, the gene frequencies differed in the Holsteins maintained at moderately high altitude (descended from Holsteins kept at sea level), and may have been reflective of the need to adapt to moderately high altitude and chronic hypoxemic conditions. Blood group polymorphism was found in all groups of cattle, although it was reduced in the Vacas de lidia, possibly because their breeding has been carefully controlled and they appear to be highly inbred.

Abstract:
Assisted reproductive technologies (ART) that have come to stay and are still being improved upon in developed countries are still in their infancy stage in developing countries like Nigeria. Nigeria’s cattle population is estimated to be around 18.4 million. The number is far insufficient to meet the country’s demand for meat, milk, and other cow products, let alone contribute to GDP. N’dama and Muturu are both Nigerian breeds that are resistant to trypanosomosis. They are humpless longhorn and humpless shorthorn types of beef cattle. The dairy and beef cow industries’ inadequate adoption of ART is partly to blame for Nigeria’s low cattle output. Sex determination, multiple-ovulation and embryo transfer (MOET), oestrus synchronization, artificial insemination (AI), in vitro fertilization (IVF), cloning, and genetic engineering are all examples of assisted reproductive technologies. It has been reported in humans, rodents and domestic animals, abnormal fetuses, newborns and adult offspring arise from ART. Improper matching of breeding animals mostly leads to overfat calves. This review centers on the applications and potentials of ART in the production of trypanotolerant N’dama and Muturu cattle breeds. Some unorthodox medicines which have proven effective in human reproduction can circumvent the shortfalls in the adoption of ART.
