(Scientific Research, 2013) Adeyemo, G.O; Oyinlola, K.T.; Longe, O.G.
One hundred and forty four day-old Marshall Chicks were randomly assigned to six dietary treatments to assess the influence of a cocktail enzyme (maxigrain) on the carcass characteristics, visceral organ weights and gut morphology of Marshall Broilers. Completely randomised design was used for the study consisting six diets. Diet 1 was the control diet without enzyme, Diet 2; control diet with 0.1% Maxigrain inclusion, Diet 3; 5% energy reduction without enzynne, Diet 4; 5% energy reduction with 0.1% Maxigrain, Diet 5; 5% protein reduction without enzyme and Diet 6; 5% protein reduction with 0.1% Maxigrain. Diets were replicated four times with each replicate having 6 birds. Completely radomised design was used while the level of significance employed was p<0.05 Results indicates that carcass characteristics observed show that only drumsticks were significantly influenced by enzyme supplementation (p<0.05). Gizzard, (3.80g) spleen (0.20g) and abdominal fat (1.60g) were also significantly affected by Maxigrain supplementation. Values obtained for gut morphological assessment of the ileum and jejunum showed significant improvements (P<0.05) in the crypt depth, 130.30pm, 136.26pm villus height 111 1.80pm, 1426.90pm and villus to crypt ratio 12.82, 13.35 respectively, as a result of Maxigrain supplementation.
Effect of dietary biscuit waste on performance and carcass characteristics of broilers
(Scientific Research, 2013) Adeyemo, G. O.; Oni O. R.; Longe, O.G.
A study was conducted for 8 weeks to investigate the effect of dietary biscuit waste (BW) replacing maize (M) on performance and carcass characteristic of broilers. A total of 175 day old marshal broiler chicks were used for this study. They were completely randomized and divided into five treatments. Each treatment had five replicates of seven birds per replicate. Five experimental diets were formulated as follows; A: (100%M: 0%BW), B: (75% M: 25%BW), C: (50%M: 50%BW), D: (25%M: 75%BW), E: (0%M: 100%BW) at both starter and finisher phases. Performance indices measured were feed intake, weight gain and feed conversion ratio. The feed intake (F.I.) was affected with increasing level of biscuit waste. There were significant differences (p<0.05) across the treatments with treatment A having the highest value of 2.92kg for F.I and treatment E having the least value of 2.51kg while treatments B, C and D followed the same trend having the following values of 2.73kg, 2.70kg and 2.61kg respectively. Average weight gain showed that there were no significant differences (p>0.05) across the treatments, the values obtained were 1.13kg, 1.09kg, 1.10kg, 1.12kg and 1.10kg for treatments A, B, C, D and E respectively. Feed conversion ratio showed significant differences (p˂0.05) as birds in treatments C, D and E recorded lower values of 2.47%, 2.37% and 2.33% respectively while birds on treatment A had highest value of 2.60%. The carcass weights expressed as percentages of live weights (LW) did not show any significant differences (p>0.05). The result for breast weights showed significant differences (p˂0.05) as birds on treatments four (25% M: 75% (BW) and five (0%M: 100% BW) had lower values of 10.05% (LW) and 11.20% (LW) respectively. Surprisingly, birds on treatment two (75% M 25% BW) had the highest breast meat value of 16.75%. The percentage organ weights showed no significant differences (p>0.05) between liver, heart and spleen but the gizzard weights were significantly different among the treatments with the control having the highest value of 2.88% (LW). It was concluded that biscuit waste could be used as feed for broilers up to 50% replacement levels for maize at the starter and finisher phases without compromising performance and carcass value of broilers.
