“…This dramatic reduction in GWP was attributed to higher quality forage with increased digestibility in the alternative system, resulting in faster LWG. Mogensen et al (2015) estimated CFs of beef production systems in Denmark and Sweden. The system boundary was from cradle to farm gate and the FU was 1 kg carcase weight (CW).…”

“…However, there are ethical considerations about wasting this resource and animal life, besides the obvious in that a prerequisite for the dairy cow to give milk is to give birth of a calf. Furthermore, there are concerns about the impact on climate change of such an alternative, as replacing dairy calves with beef suckler calves can double the amount of greenhouse gases emitted per kg meat (Mogensen et al, 2015).…”

“…It has been shown that the proportion of forage can be increased up to at least 60% without any adverse effects on milk production (Patel, 2012), and can thus be used to lower the dependency of dairy cows on feeds edible to humans. However, replacement dairy heifers and beef cattle in Sweden today are already fed a rather high proportion of forage (Hessle et al, 2004;Mogensen et al, 2015).…”

Efficiency in animal protein production can be defined in different ways, for example the amount of human-digestible essential amino acids (HDEAA) in the feed ration relative to the amount of HDEAA in the animal products. Cattle production systems are characterised by great diversity and a wide variety of feeds and feed ration compositions, due to ruminants' ability to digest fibrous materials inedible to humans such as roughage and by-products from the food and biofuel industries. This study examined the upgrading of protein quality through cattle by determining the quantity of HDEAA in feeds and animal products and comparing different milk and beef production systems. Four different systems for milk and beef production were designed, a reference production system for milk and beef representing typical Swedish production systems today and three alternative improved systems: (i) intensive cattle production based on maize silage, (ii) intensive systems based on food industry by-products for dairy cows and high-quality forage for beef cattle, and (iii) extensive systems based on forage with only small amounts of concentrate. In all four production systems, the quantity of HDEAA in the products (milk and meat) generally exceeded the quantity of HDEAA in the feeds. The intensive production models for beef calves generally resulted in output of the same magnitude as input for most HDEAA. However, in beef production based on calves from dairy cows, the intensive rearing systems resulted in lower output than input of HDEAA. For the extensive models, the amounts of HDEAA in meat were of the same magnitude as the amounts in the feeds. The extensive models with beef calves from suckler cows resulted in higher output in meat than input in feeds for all HDEAA. It was concluded that feeding cattle plants for production of milk and meat, instead of using the plants directly as human food, generally results in an upgrading of both the quantity and quality of protein, especially when extensive, forage-based production models are used. The results imply that the key to efficiency is the utilisation of human-inedible protein by cattle and justifies their contribution to food production, especially in regions where grasslands and/or forage production has comparative benefits over plant food production. By fine-tuning estimation of the efficiency of conversion from human-edible protein to HDEAA, comparisons of different sources of protein production may be more complete and the magnitude of amino acid upgrading in plants through cattle more obvious.

“…Probably, much less attention has been devoted to other "natural" sources of global heating. For instance, nowadays agricultural production is responsible for about 10% to 12% of global greenhouse gas (GHG) emissions [3] [4]. A significant part of global warming is derived from the production of gases, collectively known as greenhouse gases (GHG).…”

“…Probably the most relevant gases responsible by temperature rise are carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O). These gases, together with other components, such as ammonium (NH 3 ) and other nitrogen compounds, are usually generated in animal and agricultural activities. Here we will focus on the deleterious effects of gas production due to rice harvesting.…”

This paper describes the major environmental aspects related to the cultivation of rice. Rice is one of the most important agricultural products and it is cultivated in almost all countries in the world. Its production requires usually large flooded areas. Under these conditions, many greenhouse gases are generated, such as carbon dioxide, methane, nitrogen oxides and its derivatives. Cultivation of rice is responsible by the release of relevant amounts of these gases and contributes decisively to global warming. In this sense, the major points described here are general environmental aspects, the mechanisms of production of greenhouse gases, bioremediation, mitigation using other techniques and possible improvements of the cultivation by fertilizers and chemicals.
