Commonwealth Contributions and British Requirement of Fruit
Commonwealth contributions to the British diet 83 Thus, the supplies of bacon from Commonwealth sources are unlikely to increase as fast as supplies from home production, and supplies from European sources are already increasing. There is, however, one new possibility in the future, the production of pigs as part of the grain-sorghum scheme in Queensland. It is too soon as yet to estimate the potentialities of this scheme, but one word of caution is necessary. Sorghum can be used to replace only such foods as maize in the fattening of pigs. Adequate supplies of protein-containing foods for sows and weaners will, therefore, be the limiting factor in this form of pig production. The success of the scheme will thus depend upon one or both of two factors, the discovery of new supplies of feeding-stuffs containing animal protein, and the more efficient use of present supplies. There is no doubt that feeding-stuffs containing animal protein have been used very wastefully in the past and could be used far more efficiently in the future. The discovery of cheap sources of vitamin q2 also would help with the large-scale production of store pigs for fattening on sorghum.
Australia's Contribution to the British Diet
Commonwealth contributions to the British diet 53 a great agricultural country and having large manufacturing plants as well, she can never hope to buy as much as she sells. Thirteen and a half million people cannot buy as much as fifty million, but they can produce food for Great Britain in large quantities. The key to the situation is the question of a more plentiful supply of dollars for the purchase of essential foods in friendly Canada.
Genetics of the phenotypic evolution in sheep: a molecular look at diversity-driving genes
Background After domestication, the evolution of phenotypically-varied sheep breeds has generated rich biodiversity. This wide phenotypic variation arises as a result of hidden genomic changes that range from a single nucleotide to several thousands of nucleotides. Thus, it is of interest and significance to reveal and understand the genomic changes underlying the phenotypic variation of sheep breeds in order to drive selection towards economically important traits. Review Various traits contribute to the emergence of variation in sheep phenotypic characteristics, including coat color, horns, tail, wool, ears, udder, vertebrae, among others. The genes that determine most of these phenotypic traits have been investigated, which has generated knowledge regarding the genetic determinism of several agriculturally-relevant traits in sheep. In this review, we discuss the genomic knowledge that has emerged in the past few decades regarding the phenotypic traits in sheep, and our ultimate aim is to encourage its practical application in sheep breeding. In addition, in order to expand the current understanding of the sheep genome, we shed light on research gaps that require further investigation. Conclusions Although significant research efforts have been conducted in the past few decades, several aspects of the sheep genome remain unexplored. For the full utilization of the current knowledge of the sheep genome, a wide practical application is still required in order to boost sheep productive performance and contribute to the generation of improved sheep breeds. The accumulated knowledge on the sheep genome will help advance and strengthen sheep breeding programs to face future challenges in the sector, such as climate change, global human population growth, and the increasing demand for products of animal origin.
