Growth Pattern Analysis of Crossbred Chicken Feed Different Level Protein

Crossbred chickens are a new breed of chicken whose nutritional needs are not yet known. The protein content of the ration will affect the growth rate of poultry. Growth patterns are used to predict the nutritional needs of livestock including the need for protein, energy, minerals and the appropriate harvest age. Used 192 crossbred chickens. This study was conducted using the in-vivo method using a completely randomized design (CRD) consisting of 3 treatments and 8 replicates. The treatments were as follows: T1) Crude protein 18% for starter and 16% for finisher. T2) Crude protein 20% for starter and 18% for finisher.T3) Crude protein 22% for starter and 20% for finisher. The research data obtained were tabulated and analyzed using descriptive and quantitative. The results showed that treatment 3 achieved the best results with a body weight of 801 grams and a growth pattern of 466%. The use of feed with crude protein levels of 22% (starter) and 20% (finisher) produced the best body weight analyzed using growth patterns. This growth pattern can be used as a parameter of the suitability of protein feed given to the needs of local chicken crosses at each phase.IJSRED-International Journal of Scientific Research and Engineering Developmen
