Abstract:

The term biotechnology has been defined as the application of biological organisms, systems or processes to manufacture and service industries (Anon, 1980) and is, therefore, more than the application of ‘genetic engineering’ techniques alone. The potential application of biotechnology to the agricultural livestock industry includes many wide ranging areas: animal health; breeding; livestock production; livestock nutrition and the nutritive value of feeds. The role of biotechnology in animal nutrition and feeding is of particular importance since feed costs account for a significant proportion

Abstract:

AbstractEnvironmental and economic performances of livestock production are related largely to the production of complete feeds provided on commercial farms. Formulating feeds based on environmental and economic criteria appears a suitable approach to address the current challenges of animal production. We developed a multiobjective (MO) method of formulating feed which considers both the cost and environmental impacts (estimated via life cycle assessment) of the feed mix. In the first step, least-cost formulation provides a baseline for feed cost and potential impacts per kg of feed. In the s

Fibrous feeds mostly of crop residues, green grasses, and tree foliages and leaves support bulk diets of farm animals being raised mostly by smallholders. The roughage DM produced (51056 million kg) surpasses its demand (49200 million Kg) by 3.77%, but losses and otherwise uses result in production deficit of 44.5%. An average 56.2% deficit of roughage DM and 80.0% of concentrate DM results in a very poor plane of nutrition for farm animals. It supports an average diet containing 6.75 MJME/Kg DM and 1.63% DCP with the feed produced or 7.74 MJME/Kg DM and 2.32% DCP with the feed available, whil

The main requirement for feeding livestock is its high intensity. The production of feed in accordance with the requirements of animals requires accurate measurement of their quantity and quality. Among the large number of traits that characterize plants, some of them can be considered as indicators that change in close connection with the productivity of animals. The concept of quality is close to the concept of feed nutrition.

Meat, milk, and egg contribute positively to the nutrition and health of humans; however, livestock requires a large number of resources, including land for fodder and grains. Worldwide millions of tons of vegetable waste are produced without any further processing, causing pollution and health risks. Properly managed vegetable waste could provide a source of feed for livestock, thus reducing feeding costs. In this regard, pumpkin waste (Cucurbita sp.) is an alternative.

Abstract:

Managing the mineral nutrition of free-range grazing livestock can be challenging. On farms where grazing animals are infrequently yarded, there are limited opportunities to administer trace element supplements via feeds and concentrates. In New Zealand, where the majority of sheep, cattle, and deer graze pasture year round, inadequate intake of cobalt, copper, iodine and selenium is prevalent. Scientists and farmers have developed efficient strategies to monitor and treat these dietary deficiencies. Supplementation methods suited to grazing livestock include long-acting injections, slow-relea

Abstract:

Milk, meat and eggs tend not to be regarded as an important source of PUFA. They are disproportionally high in SFA compared with their PUFA content, especially those from cattle and sheep, since their rumen microbes are responsible for the loss of over 90 % of PUFA intake by livestock. This need not necessarily be the case since the relative proportion of PUFA in these foods is dictated by livestock management, especially feeding, and this can be manipulated to boost their content of crucial long-chain n-3 fatty acids and conjugated linoleic fatty acids.

Abstract:

Environmental pollution is defined as the disruption of normal ecological balance with emmision of various substances and energy residues as a result of human activities. Animal production is one of the major human activity that enables this emission to increase significantly. Although ruminants play an important role in the effects of animal production on environmental pollutant emissions, the effects of poultry production and broiler production are also worth considering. As in all livestock types, the main factor that has a direct impact on environmental pollutant emissions is feeding for t

Grass is a complex crop and its value for agriculture must be assessed in terms of the quantity and quality of downstream livestock products (milk, meat and wool). In addition to being a natural low-cost feed for ruminants, grassland protects soil and water resources and enhances the landscape. Temperate grasslands support a major share of the world's milk and beef production but now there is increasing emphasis on sustainability in livestock farming systems rather than maximizing outputs. The economic sustainability of livestock producers in many developed temperate regions is increasingly li

AbstractThe present review summarises the potential nutritional and physiological functions of betaine as a feed additive in relation to performance criteria in livestock production. Betaine, the trimethyl derivative of the amino acid glycine, is a metabolite of plant and animal tissues. In plants, betaine is particularly synthesised and accumulated as an osmoprotectant against salt and temperature stress. In animals, betaine is the product of choline oxidation or it originates from nutritional sources. Over the past decades, numerous studies have been carried out to investigate the potential

Feed is one of the important factor that affect livestock productivity, so the availability of good quality feed is a requirement for livestock development in an area. In the tropical area, providing forage as a crucial feed for ruminants was hampered by fluctuating seasons. Likewise, the availability of agricultural waste as an alternative source of feed material experiences the same constraints, easily damaged, and bulky (voluminous). Therefore, feed processing technology is needed so that it is become durable, easily stored, and easily provided for livestock. One way to overcome this is to

A significant role is also played by the animal species, dosage, and the time and method of administration. The activity of these compounds is primarily focused on prevention of pathogen infections and, consequently, improvement of animal welfare. Probiotics compete with pathogenic b

Energy balance is the net result of the energy intake (nutrition) and expenditure (basic metabolic rate). The purpose of the daily feed intake is to provide energy and nutrients for maintenance, production and fill and maintain energy storages in form of glycogen and fat. Animals can adjust their feed intake to ensure their energy demand. Food intake regulation in animals and human is a very complex process, in which the digestive system, the central nervous system, the joining hormonal and non-hormonal factors, and the integrating hypothalamus take part.

The model predicts protein and fat deposition as well as the body weight of an individual broiler chicken from digestible nutrient intake over time.

Conjugated linoleic acids (CLA) have been shown to have anti-carcinogenic, anti-obesity, anti-atherogenic and immunomodulatory functions. The basis for these effects has not been fully explained, but probably involves effects of CLA on eicosanoid metabolism, cytokine production and\or gene expression. The predominant isomer (85–90%) in the natural sources of CLA has thecis-9, trans-11 configuration. As interest in CLA grew and synthetic forms became available, the number of studies examining the effects of dietary CLA in rodents, human subjects and livestock has increased greatly. In the late
