“…This leads to an increase in the daily gain of young broilers as shown in our result. Mandey et al (2017) also reported a good value of carcass percentage in broilers fed a diet containing 11% of crude fiber and about 11% of fat level.…”

The physiological effect of insoluble fibers may change with diet composition. The present study aimed to determine the difference in the physiological responses of broiler chickens fed diet incorporated with rice hulls in different ways. Two hundred and forty broiler chicks at two-days old were randomly placed in 30 cages and fed: control diet (based on corn-soybean) (CO), rice hull supplementation diet (CO + 4% of rice hulls) (RS), and rice hull inclusion diet (inclusion of 4% rice hulls in diet) (RI). The significant effects were mostly found in the starter phase. The RI increased ADG (P<0.05) but reduced empty ceca weight (P<0.05) in comparison to CO and RS. The RS increased the jejunal crypt depth (P<0.05) and reduced the small intestinal content (P<0.05). Birds fed RS and RI had higher villus height (P<0.05) and thicker jejunal mucosa (P<0.05) than those fed the CO. In the finisher phase, birds fed the RS had the narrower width of the upper and lower jejunal villi than the others. Supplementation or inclusion of insoluble fiber in the diet will lead to different physiological responses due to changes in diet composition.

“…The concentrations of T-CHO, LDL and HDL are important indexes that reflect the level of lipid metabolism. A study showed that 11% CF levels could improve blood lipid metabolism in broilers [ 49 ]. Similarly, 8% and 11% CF levels in broiler diets significantly reduced the plasma T-CHO content in the current study.…”

There are few systematic studies on the dietary fiber requirements of broilers in the late feeding stage, and there are not enough data to support this hypothesis. This experiment was conducted to examine the effects of dietary fiber level on growth performance, nutrient digestibility, immune function and intestinal morphology of broilers from day 22 to 42. A total of 480 one-day-old Arbor Acres broilers with half male and half female were randomly allocated into four groups, with eight replicates in each group and fifteen chickens in each replicate. The experimental period was 42 days. All broilers were fed a basal diet from 1 to 21 days. During the 22–42 day period, the four experimental groups were fed diets with soybean hulls as the fiber source, and crude fiber (CF) levels were 2%, 5%, 8% and 11%, respectively. The results showed that during the 29–42 day period, the average daily feed intake (ADFI) of broilers was higher in the 5% CF and 8% CF groups (p < 0.05), and during the 29–35 day period, the average daily gain (ADG) of broilers was higher and the ratio of feed and gain (F/G) of broilers was lower in the 5% CF and 8% CF groups (p < 0.05). The digestibility of crude protein (CP), ether extract (EE), CF, acid detergent fiber (ADF) and neutral detergent fiber (NDF) was higher in broilers of the 8% CF group (p < 0.05). The immunoglobulin A (IgA), immunoglobulin G (IgG) and immunoglobulin M (IgM) content of the plasma of broilers was higher in the 8% CF group (p < 0.05). The villus height (VH) of the duodenum, jejunum and ileum of broilers was higher, and the crypt depth (CD) was lower in the 8% CF group than that in the 2% CF group (p < 0.05). The ratio of VH and CD (V/C) of the duodenum and jejunum of broilers in the 8% CF group was higher than that in the 2% CF group (p < 0.05). The quadratic regression analysis showed that the optimum dietary CF level was 7–9%. In conclusion, under the conditions of this experiment, a diet of 7–9% CF may promote growth performance by improving the nutrient digestibility, immunity and intestinal morphology of broilers from day 22 to 42.

“…Xanthophil compounds, such as lutein, zeaxanthin, meso-zeaxanthin, astaxanthin, and canthaxanthin are carotene oxygen derivatives [25]. In addition, lower levels of meat cholesterol in treatments A and B can be caused by the high content of crude fiber in carrot leaves, which plays an important role in binding and eliminating cholesterol [26,27,28]. The increase levels of crude fiber in feed can reduce feed consumption, percentage of abdominal fat, and LDL-blood cholesterol, but do not affect final body weight [29].…”

This study aims to observe the effect of concentrated levels in carrot leaf based feeds to improve performance, carcass and β-carotene content in local rabbit meat at 8 weeks. This study used a feed experiment using 120 local 8-week-old male rabbits divided four group treatments and 6 replications. The four group treatments were rabbits fed on carrot leaf based rations with supplementation: 0% concentrate as a control (A), 10% (B); 20% (C); and 30% (D), respectively. Each treatment consisted of six replication cages with five rabbits per cage. The results showed that feed consumption, final body weight, weight gain, carcass weight, and percentage of carcasses in Groups B, C and D, were significantly (P<0.05) higher than Group A. The lowest cholesterol content was found in rabbits group A (P<0.05). In contrast, the highest beta-carotene levels of meat (P<0.05) were found in group A. It was concluded that supplementation of 10-20% concentrate in carrot leaf based rations could increase live weight gains, carcass weight, carcass percentage, and feed efficiency in local rabbits up to 8 weeks old. The highest content of β-carotene in rabbit meat was found in feeding 100% of carrot leaves.
