Performance, carcass and noble cuts yield of broilers fed diets supplemented with Solanum glaucophyllum
The objective was to evaluate the performance of broilers from 8 to 42 days of age, fed with diets supplemented with active vitamin D3. It was used 648 broilers, males, Cobb®, distributed among six treatments (0.0; 0.5; 1.0; 1.5; 2.0 and 2.5 D3/kg of ration) using a randomized block design, with six...

| Summary: | The objective was to evaluate the performance of broilers from 8 to 42 days of age, fed with diets supplemented with active vitamin D3. It was used 648 broilers, males, Cobb®, distributed among six treatments (0.0; 0.5; 1.0; 1.5; 2.0 and 2.5 D3/kg of ration) using a randomized block design, with six repetitions of 18 birds each. At 8 and 42 days of age each experimental unit and the rations were weighted in order to evaluated the performance (feed intake - FI, weight gain - WG and feed conversion - FC). Later, three broilers/repetition were removed and slaughtered in order to measure the absolutely weight, carcass and noble cuts yield. The average carcass, breast, thighs, drumsticks and wings were 70.17%, 37.09%, 14.08%, 18.31% and 10.44%, respectively. The levels of active vitamin D3 did not influence (p>0.05) performance, nor the carcass and noble cuts of broilers. Including up to 2.5 ?g/kg in ration of active vitamin D3 did not influence (p>0.05) the performance and carcass and noble cuts yield of broilers. |
