Broadening Horizons N°31, July 2016

By Harinder P. S. Makkar

Animal nutrition is the foundation of livestock production systems and a multifaceted theme. It is not only the science of feed preparation and feeding – it influences almost every sector of the livestock production – from animal reproduction, health and welfare – to farm economic viability, environment, animal product safety and quality. This paper intends to weave strands from these domains with animal nutrition and overall sustainability of the livestock operation.

It has been long known that severe undernutrition of pregnant cows and sheep, especially during late gestation, can permanently retard body and wool growth of their offspring. However, the idea that maternal nutrition at various stages of pregnancy can indelibly influence lifetime productivity and health of progeny has gained additional currency from more recent epidemiological studies of human populations and detailed experimental studies of rodents as well as livestock species.

In many tropical areas, areca nut (Areca catechu) production has been steadily increasing at the expense of paddy rice. It results in less straw available to cattle and a new crop residue: areca sheath. Areca sheath, when properly processed, can be fed to ruminants: it provides valuable fodder and could reduce feed cost in India.

In dry areas, harveting annual cash crops is risky. Perennial adapted crops are the best alternative to produce food for humans and feed for livestock. Livestock production systems mostly rely on rangelands. However, rangelands in arid and semiarid areas have only low productivity and the increasing stocking rate may lead to their degradation. Water is also a limiting factor. In this scenario, cactus (Opuntia and Nopalea) are one of the most promising fodder for livestock.

Livestock account for approximately 14.5% of all anthropogenic greenhouse gas (GHG) emissions. Demand for animal products is expected to increase by 60-70% in the coming approximately three decades, which could put further pressure on already depleting natural resources. The production, processing and transport of feed accounts for about 45% of the GHG emission from the livestock sector. There is thus a clear need to use smart feeding strategies, which could enhance resource use efficiency, increase animal productivity and reduce environmental "hoofprint". Some of such strategies are described in this paper. Many other examples are illustrated in Feedipedia datasheets.

Climate change will have an impact on livestock performance in many regions and as per most predictive models the impact will be detrimental. Animals will have to face weathers extremes, e.g. intense heat waves, floods and droughts and will also be offered less feeds or poorer quality feeds. This paper makes an attempt to project the adverse impact of climate change on livestock production and the potential way of alleviating it.

A global model system was designed in order to calculate various scenarios of food availability and impacts of food production on the environment. This model can be used in the future to answer various questions on the sustainability of agricultural and food systems.

Broadening Horizons N°24, December 2015

As the EU faces both a deficit in protein sources for animal feed and calls to create a zero-waste, circular economy, there is a growing mandate to reconsider the ban on swill. Regulating, rather than prohibiting, the use of food waste as pig feed could safely produce high-quality pork, with substantial economic and environmental benefits.

Broadening Horizons N°23, November 2015

Food and Agriculture Organization of the United Nations (FAO) and Texas A&M (TAMU) are working together to deliver an aflatoxin proficiency testing programme. Registrations for this new free proficiency program are now open till 31th of december 2015.

Broadening Horizons N°22, October 2015

By J.-F. Hocquette (INRA) and L. I. Laestadius (Univ. Wisconsin-Milwaukee)

Articificial meat made from cultured stem cells could be an alternative to traditional meat. It would need fewer farm animals and would address the challenge of producing enough meat for our increasing human population. However, production techniques still need to become more efficient and economically sustainable. Public receptiveness towards artificial meat is also ambivalent and other alternatives to enhance protein production within 25 years will have to be taken into account.

The following 4 webinars are based on an FAO e-course and cover 16 modules/lessons tailored for extension workers, progressive farmers, technical staff of the producer organizations, students and teachers.

A short presentation of the course can be viewed here.

An FAO electronic conference on "Utilization of Food Loss and Waste as well as Non-Food Parts as Livestock Feed" will be held from 1 to 30 October 2015.

Providing the right combination of nutrients in the adequate amounts is the foundation for ensuring good animal performance, health, and welfare for calves, cows, beef and pasture-raised livestock.

Defining the status (wet, non-pregnant; wet, pregnant; dry, pregnant; dry, non-pregnant) of milking cows in tropical dairy farms is a useful tool to manage feeding and herd management. Good observation skills and a regular collection of data are necessary to provide consistent supply of nutrients to sustain milk yields.

Organic sources of trace minerals play an important role in metabolic events in the body. In their organic form, minerals are protected from interactions with fibre, phytate, tannin and other susbtances. They have improved bioavailability and their use results in reduced environmental contamination.

Plant breeding has large and strategic potential for global feed and food security. Both breeding technologies, conventional and genetic may contribute to solving important challenges, such as sustainable use of limited global resources, improved use of unlimited resources, adaption to climate change and lowering of global greenhouse gas emissions.

NIRS theory in a few words

Spectroscopy refers to the science dealing with the interactions between matter and light. In the infrared region (780 – 10 000 nanometers – Figure 1), the light hitting organic matter can be absorbed by the molecular vibrations at specific wavelengths depending on the chemical bonds (OH, CH, NH, etc.).

On hearing jatropha (Jatropha curcas) two things come to mind:  it is an oil plant and its seeds are toxic. However, a non-toxic genotype of J. curcas exists in Mexico. Its seeds are consumed by people after roasting. Also after removal of the seed shells the kernel paste is used in local dishes in some parts of Mexico.

As the demand for animal protein continue to increase, global animal production faces several challenges in order to meet these demands because of environmental challenges (global warming and climate change). Furthermore, the intensification of animal production systems might compromise animal health and welfare and consequently increase the incidence of the metabolic diseases. Ruminant health and production is crucial for a sustainable animal production system, and this area of research is now attracting international interest, especially the mechanisms by which antioxidant supplementation may influence metabolism and health.

Introduction

There has been a major shift to diets with increased consumption of animal products, and this change is likely to continue in the coming decade. The demand for meat and milk is expected to be 58% and 70% higher in 2050 than their levels in 2010 and a large part of this increase will originate from developing countries.
