Ruminant Livestock

The importance of copper (Cu) for the proper functioning of many biological systems is well recognized. Copper deficiency significantly affects ruminant livestock production in large areas of Canada as well as many other parts of the world. Selected aspects of recent research into Cu deficiency in ruminants have been reviewed, including the biochemistry and physiology of Cu deficiency as well as the metabolism of Cu. Because of the wide occurrence of Cu deficiency in ruminants grazing in areas of high molybdenum (Mo) and/or sulfur (S), research on the mechanisms of interference in Cu metabolism has received wide attention. Similarities in the physiological effects of the combination of molybdate and sulfide (or sulfate) and of thiomolybdates in ruminants, strongly suggest that thiomolybdates are primarily involved in the induction of Cu deficiency. Thiomolybdates appear to induce Cu deficiency by (i) limiting Cu absorption, (ii) binding Cu in albumin, thus delaying Cu uptake by the liver, (iii) depleting liver Cu, (iv) altering liver Cu and Cu from other tissues to a less available form, (v) increasing biliary Cu excretion, (vi) limiting reabsorption of biliary Cu, (vii) increasing urinary Cu excretion, and (viii) increasing endogenous secretion of Cu. Copper, S and/or Mo have also been identified as factors in the etiology of polioencephalomalcia and abmosal ulcers but the mechanisms involved are not clear.

The survival of the extensive livestock system, the practice for most farmers in the livestock industry in Ghana depends heavily on the natural pastures as forage resource. To efficiently use the rangelands, knowledge of the species composition, especially that of poisonous plants is essential. Documented knowledge in Ghana is scanty; documentation and dissemination of the knowledge resource would enable a wider access and wider benefit to stakeholders. A study was conducted in Ghana on poisonous plants with the aim to discover the existence and diversity of poisonous plants and associated antidotes affecting livestock for documentation and preservation of knowledge. 70 different items were cited; 22 were poisonous plants for which antidotes were not cited, 28 were poisonous plants with known antidotes and 32 antidotes. There were 575 citations of plants from 194 reported cases of suspected plant poisoning, categorized as poisonous plants for which no antidotes were cited (146), poisonous plants with cited antidotes (147) and antidotes (282). 50 plants species were identified and belonged to 29 plant families. Some plants were known only by local names. There was an extensive knowledge of the diversity of poisonous plants and antidotes within the ecological zones along with possible antidotes.

Abstract The relationship between nutrition, production and environmental aspects of ruminant livestock production systems is a complex and highly nuanced subject that has long suffered from oversimplification and assumptions associated within these practices. However, with the advent of new and evolving models and a growing understanding of these complexities and their interactions with each other, there has been a large and welcome growth in recent literature regarding new and emerging technologies, and insights that will allow for appropriate and impactful changes in livestock management that will affect overall change for the benefit of society as a whole. The primary means through which environmental impacts may be modified are separated into four distinct, but interconnected mechanisms, which include 1) improvements in use of dietary nutrients, 2) use of dietary additives that impact certain functions in the digestive tracts of the animal, 3) improvements in genetics, and 4) improvements in productive efficiency. While it is obvious that there are significant overlaps between these practices, it is imperative to consider all these aspects to prevent “leakage” of impacts to other industries and processes. In this presentation, we will review recent developments in all of these areas with a specific emphasis on the use of energy in ruminant production systems.
