Thanks for your free communication on the ‘Nutritional Status of Family Poultry in Bangladesh’. A biological relationship could be deciphered from your data on energy and protein utilization based on seasonal variations. For example, during the summer months protein intake as determined by crop content appears higher, which could be related to lower energy requirement as a result of higher environmental temperature. In contrast, during the winter months, crop contents of energy supplying nutrient (EE, NFE) were higher most probably as a result of higher energy requirement. This observation tends to be true for most locations during the winter period.
This observation along with the variation in the seasonal availability of feed resources will permit a proper diet intervention strategy to improve productivity of scavenging chickens. However, to further look at the biological aspect of your data, information on the age of the hens used in your study, stage of production, protein to energy ratio, day length, activity level and mean ambient temperature, etc. are important.
