WHY BROILER MAY FAIL TO REACH DESIRED MARKET WEIGHT AT EIGHT WEEKS



i.  Management: Poor management practices, such as poor sanitation, weedy environment, wet litter, failure to follow manufactures instructions and poor handling of the birds could lead to poor performance of birds.

ii.  Feeding: The quantity and of feed given to the broiler could also affect the market weight. Imbalance in nutrient such as energy, protein, mineral could lead to reduced market weight. At starter phase (day old-4 weeks) the energy requirement are 23-24% cured protein and
2800-2900kcal. Me/kg  respectively. Any composition below the recommended value will lead to poor growth. Wastage of feed as a result of poor handling by attendant could also result to poor market weight.

iii.   Stocking Rate:  If the birds are over crowded, the birds will not grow very well and over population will lead to competition for food and consequently reduce the growth performance.

iv.  Breed: The genetic make up of the birds could have positive or negative effect on the performance each breeds has its own characteristics in terms of body conformation, feed efficiency and body weight at a given period, bread characterized with poor performance will fail to reach market price at a given period.

v.   Source of Day old Chicks: Poor market weight of the broiler could be as a result of the source where the day old chicks were collected failure to collect day old chick from a reputable farm could causes slow growth rate.

vi.   Disease: If disease is not well controlled the bird would not reach desired market weight at given period. Use of expired fake drugs and vaccine could lead to disease out break, which will affect the birds adversely.
