Protein requirement of guinea keets

Area of Science:

• Animal Nutrition
• Poultry Science
• Avian Physiology

Background:

• Determining optimal nutrient requirements is crucial for efficient poultry production.
• Guinea fowl (keets) represent a valuable but less-studied avian species in terms of nutritional needs.
• Understanding protein requirements supports improved feed formulation and growth performance.

Purpose of the Study:

• To ascertain the specific dietary protein levels essential for optimal growth in guinea keets.
• To evaluate the impact of varying protein concentrations on feed intake, feed conversion, and mortality.
• To establish a scientifically-backed protein recommendation for young guinea fowl.

Main Methods:

• Guinea keets were housed in battery brooders with raised wire floors from 1 to 56 days of age.
• A corn-soya based diet was formulated to be isocaloric, with varying protein levels from 18% to 28%.
• Growth performance, feed consumption, feed conversion ratio, and mortality were meticulously monitored.

Main Results:

• Guinea keets demonstrated optimal growth when fed a diet containing 24% protein.
• A 28% protein diet showed a trend towards better feed conversion, but this difference was not statistically significant (p<0.05).
• Feed consumption generally correlated with observed growth rates, and protein levels did not impact mortality.

Conclusions:

• A dietary protein level of 24% is recommended for maximizing growth in guinea keets up to eight weeks of age.
• While higher protein may slightly improve feed efficiency, 24% appears to be the most cost-effective level for optimal development.
• Further research could explore protein requirements at different growth stages or with alternative protein sources.
