1st 7-days weight in Broiler chicks.

Why 7 days weight in Broiler chicks is important ??

                 The target weight of 7 days of age should be maximum to get the full potential of broilers. The 1st 7 days of broiler chicks is vital as they utilize maximum energy (80%) for growth and for maintenance only 20%. The modern broilers are supposed to increase live weight of 4.25 times during 1st week from 40g to 80g. These weight has been increased by 8% in last 5 years. The 1st 7 days weight has significant effects on most parameters such as performance, carcass quality and body composition as due to improve nutritional maturity, accelarate development of GIT and good immuno response.
                 The 1st week body weight could be increased by feeding highly digestible raw materials since birds enzyme system is not fully developed along with high hygiene quality of material included as also the immuno system is immature. However, high quality feed presentation, correct brooding tempreture, easy access to feed, increase frequency of feeding, checking of crops and grading of chicks are the most important criteria to acchieve maximum weights in broiler chicks.
