research results and facts of climate change scenarios and the preferences of animal species
that reared for animal protein productions were reviewed with the aim of
delivering synthesized information for the beneficiaries. Both of the climate change and animal productions have always negative
impacts one over the other. Livestock is responsible for 18% of GHG emissions
measured in CO2-eq. Upcoming animal protein supply and demands will
pose a challenge to the environment. However, due to its low global warming
potential, poultry has advantages over other livestock industries. Chicken is
the cheapest, without taboos and nutritious of all livestock meats but the red
meat industry is a pro-active for environmental concerns. Birds, however,
tolerates a narrow temperature ranges and are vulnerable to climate changes. There is a positive relationship between the
level of income and the consumption of animal proteins. As a result, animal
protein production is projected to double by 2050. Consequently, poultry
consumption is expected to grow at 2-3% per year and its share is also around
33% of the total meat produced in the world. The average per capita consumption
of poultry is around 11 kg. Technology favors the intensification of poultry
production in developing countries but environment and health issues will be
the concern. A grain yield is adversely affected by warming that leads to
food-feed competitions. This competition gives rise to looking for alternative
feeds and other utilizing techniques to improving the nutritive values of poor ingredients. It needs 2 and 4 kg of
cereals, to produce 1 kg of chicken meat and pork, respectively. This shows
that chicken is relatively efficient in feed conversion ratio than other livestock. It is therefore,
concluded that to coping up with climate changes, poultry is the preferred species of farm
animals that allowed for protein food productions. Moreover, it is also the
preferred species of farm animal that will satisfy the demands of protein foods
of the people.
