Protein requirements of growing indigenous chickens during the 14 - 21 weeks growing period
A study was conducted to investigate the growth response of growing indigenous chickens between 14 and 21 weeks of age to diet protein level. The chickens were offered diets ad libitum with 100, 120, 140, 160 and 180 g crude protein (CP)/kg diet. Body weight and feed intake of the birds were recorded weekly. Feed intake and weight gain increased significantly between the 100 and 160 g CP/kg die...
متن کاملCrude protein and amino acid requirements of growing-finishing Holstein steers gaining 1.43 kilograms per day.
Holstein steers (164 kg) were used in a 70-d growing-finishing trial. Treatments were 1) basal diet (85% concentrate); 2) basal diet plus 1.5% blood meal (BM); 3) basal diet plus 3.0% BM and 4) basal diet plus 4.5% BM. Dietary crude protein levels were 12.5, 13.7, 14.8 and 15.9% for Treatments 1 through 4, respectively. Energy intake was restricted to allow for a daily weight gain of 1.43 kg. T...
متن کاملProtein requirements of growing lambs.
I . The protein requirements of lambs were established by measuring nitrogen balance in seventy-four animals given liquid diets which passed direct to the abomasum. Four groups of lambs weighing approximately 8 kg (group I), 13 kg (group z), 21 kg (group 3) and 30 kg (group 4) received diets in which 0-10, 0.15, ozo,o'z5, 0 . 3 0 , 0 3 5 or w4oof thedigestibleenergy was provided as protein (DPE...
متن کاملImprovement of Nigerian Crude Residue
This research investigates how the properties of the Nigerian crude residue can be improved on to enhance its local usage. Chemical treatment was carried out on Nigerian crude residue and its rheological properties were tested. The physiochemical propertiesspecific gravity cum viscosity measured after the treatment gave 12.44% improvement in specific gravity and 17.92 times improvement in visco...
متن کاملMetabolizable protein and amino acid requirements of growing cattle.
Metabolizable protein and amino acid requirements for growing cattle were estimated using data from 11 research trials. A total of 543 steers were individually fed a high-roughage diet supplemented with protein at several levels above a urea supplement control. The mean weight for all animals was 253 kg, with a range in mean initial to final weights of 200 to 316 kg, respectively. Daily gain ra...
