“…It was not statistically different among groups. Previous studies reported the same findings ( (Sekeroglu et al, 2011;Turkyilmaz, 2008;Ravindran et al, 2006;Buijs et al, 2009;Skomorucha et al, 2009;El-Gogary and Azzam, 2014).…”

“…The weights of the liver, gizzard and pancreas remained unaltered by the dietary inclusion of L-Thr or stocking density. Similarly, other reported that there were no significant difference in liver and gizzard weight (p>0.05) due to stocking density (El-Deek and Al-Harthi, 2004;Sekeroglu et al, 2011;EL-Gogary and Azzam, 2014). No interaction was noted between L-Thr supplementation and stocking density in organ weight.…”

A total of 240 Cobb 500 broiler chicks, 18 days old, were allocated to 10 treatments groups, each of which included 4 replicates. Experimental treatments consisted of a 5×2 factorial arrangement with 5 levels of L-threonine (Thr) supplementation and 2 levels of stocking density (11.90 birds mG 2 as the normal stocking density or 16.66 birds mG 2 as the high stocking density). L-Thr was added to a basal diet at 0.0 (control group), 0.25, 0.50, 0.75 and 1.00 g kgG 1 diet. Dietary Thr values were 0.69, 0.71 (deficient), 0.74 (adequate; 100% NRC), 0.76 and 0. 79% (excess) of the current NRC recommendations. At 42 days of age, dietary Thr levels had no significant effect on performance, immunity, plasma total protein and glucose (GLU). However, plasma cholesterol (CHO) levels decreased significantly (p<0.05) with L-Thr supplementation and the lowest value occurred at 0.74% total dietary Thr. In addition, plasma triiodothyronine (T3) and thyroxine (T4) levels were higher (p<0.05) at 0.76% total dietary Thr compared with the control group. The normal stocking density resulted in better performance (p<0.05) compared with the high stocking density. However, stocking density did not affect plasma total protein, total Ig, IgG, IgM, total lipids, GLU, CHO, T3 and T4 levels. Interactions between Thr level and stocking density were observed for plasma levels of total lipids and cholesterol. In conclusion, total dietary Thr level at 0.69% (93% of NRC recommendations) is sufficient to improve broiler performance or immunity under high stocking density. However, 0.74% total dietary Thr level has a positive effect on decreasing plasma total lipids and cholesterol levels during growing-finishing phase.

“…This finding was similar to Estevez (2007) who reported that there was a negative consequence of high stocking on FCR. Contrary to this result Sekeroglu et al (2011) reported that there was no effect of stocking density on FCR. The average dressing percentage was significantly higher in G 2 and G 3 as compared to G 1 .…”

“…This result corroborates with the finding of Abanakgosi et al (2014) who reported that lower stocking density resulted in higher dressing percentage. Contrary to this Sekeroglu et al (2011) showed no significant effect of different stocking density on dressing percentage. In the present study there were no significant effect (P>0.05) of stocking density in the most of the carcass parts (Table 2) except the heart weight.…”

A total 90 Vanaraja experimental birds were divided into three respective groups based on floor density viz., G 1 (16 birds/m 2 ), G 2 (12 birds/m 2 ) and G 3 (8 birds/m 2 ). No significant difference in average live weight and carcass weight was observed between groups. Average feed consumption, feed conversion ratio (FCR) and dressing percentage in G 2 and G 3 was significantly (P<0.05) higher as compared to G 1 . There were no significant effect (P>0.05) of stocking density in the carcass characteristics except the heart weight. There were non significant differences among groups for total protein, albumin, globulin and A:G ratio. Blood glucose was significantly (P>0.05) higher in group G 1 as compared to G 2 and G 3 . Blood cholesterol level increased with increase in stocking density but not significantly. Blood parameters eosinophil, monocyte, basophil counts and H:L ratio were not affected by the stocking density. Hb concentration increased nonsignificantly with increased stocking density. Vanaraja birds from 8 birds/m 2 to 12 birds/m 2 give the better growth performance, FCR and dressing percentage without change in blood biochemical and hematological indices.

“…Sekeroglu et al (2011) reported that broiler reared for six weeks had fi nal body weight of 2,256 g/bird at stocking density of 17 birds/m 2 compared to that of 2,420 g/bird at stocking density of 9 birds/m 2 . Body weight gain has strong correlation with fi nal body weight.…”

This experiment was conducted to study the eff ects of dietary addition Pluchea indica L. leaf meal on performances and meat cholesterol content of broiler. One hundred sixty two DOC CP707 strain were reared for four weeks in high stocking density of 15 birds/m 2 . The birds were fed experimental diets consisted of R1 (commercial feed + Vitastress), R2 (commercial feed + 2% P. indica leaf meal), R3 (commercial feed + 4% P. indica leaf meal), R4 (commercial feed + 6% P. indica leaf meal), and R5 (commercial feed + 8% P. indica leaf meal). The data obtained were analyzed using analysis of variance (ANOVA) and any signifi cant diff erences were further tested using least signifi cance diff erence (LSD) test. The treatment signifi cantly increased (P<0.05) fi nal body weight, body weight gain, feed and water intake, and decreased (P<0.05) feed conversion ratio. It is concluded that P. indica leaf meal could be added into a diet at the level of 2%. P. indica leaf meal addition at the level of 2% into a diet is also able to decrease the cholesterol content of broiler meat up to 8%.
