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.

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.

According to a recent paper by Caro et al. published in Climatic Change, increase in greenhouse gas (GHG) emission from livestock in developing countries was 117%, while the emission from developed countries decreased by 23% during the period 1960-2010.

The demand for dairy produce is growing worldwide. Unfortunately keeping dairy cows in tropical conditions in developing countries is fraught with risks to their welfare, and performance is usually well below that achieved in western countries. Although many developing countries are currently importing much of their dairy requirements from developed countries, most governments are also expanding their own dairy industries.

Based on the papers presented and discussions held at the FAO-Wageningen UR conference on ‘Insects to feed the world’ convened in May this year, it is plausible to suggest that insect meals are promising future alternative feeds and a viable solution for the protein deficit problem.
