The Effects ofAgave fourcroydesPowder as a Dietary Supplement on Growth Performance, Gut Morphology, Concentration of IgG, and Hematology Parameters in Broiler Rabbits

Abstract

This study was conducted to determine the effects of Agave fourcroydes powder as a dietary supplement on the growth performance, gut morphology, serum concentration of IgG, and the hematology parameters of broiler rabbits. A total of 32 rabbits [New Zealand × Californian] were weaned at 35 days. They were randomly selected for two dietary treatments (eight repetitions per treatment), which consisted of a basal diet and a basal diet supplemented with 1.5% dried-stem powder of A. fourcroydes. On day 60 from the initiation of treatment, gut histomorphology (duodenum and cecum), serum concentration of IgG, and hematology parameters were all measured. The results showed that A. fourcroydes powder supplementation improved (P < 0.05) the ADFI, ADG, and final BW. Correspondingly, this treatment increased (P < 0.05) the muscle and mucosa thickness and height and width of villi. However, duodenum crypts depth was lower (P < 0.05) when rabbits were fed with this natural product, compared with the basal diet treatment. Results also indicated that the A. fourcroydes powder increased (P < 0.05) the serum concentration of IgG but did not change the hematology parameters. This data indicates that A. fourcroydes powder, as a supplement, had beneficial effects on increasing the growth performance and serum concentration of IgG, as well as improving the gut morphology without affecting the hematology parameters in broiler rabbits.

Effects of Dietary Supplementation with Red Algae Powder (Chondrus crispus) on Growth Performance, Carcass Traits, Lymphoid Organ Weights and Intestinal pH in Broilers

“…The use of these marine bioactive appears to have the same effect on the BW of growing (Table 2) and adult birds (Kulshreshtha et al, 2014). It is known that prebiotics stimulate the growth of bacterial species and improve host health, especially intestinal health (Iser et al, 2016), however, some studies in birds with these non-digestible products found no benefits in…”

Dietary Inclusion of a Mixed Powder of Medicinal Plant Leaves Enhances the Feed Efficiency and Immune Function in Broiler Chickens

“…Although it was observed that T1 increased numerically the AMEn, maybe a higher concentration of this mixed powder of medicinal plant leaves may be necessary to modify these indicators in broilers. e level of serum antibodies is currently an important indicator to know the effect of a new natural product on immune response in experimental animals [27]. An increased immunoglobulin concentration has been associated with a benefit in the immune status, and IgG and IgA are the main Journal of Chemistry immunoglobulins protecting against pathogenic microorganisms [28], mainly to intestinal level.…”

Effect of dietary supplementation with insect fats on growth performance, digestive efficiency and health of rabbits

“…Morphometric analysis was performed by Image®-Pro Plus software. The evaluated morphometric indices were: villus height (Vh, from the villous tip to the crypt bottom), crypt depth (Cd, from the crypt bottom to the submucosa) and the villus height to crypt depth ratio (Vh/Cd; Additional file 1) [34, 35]. Morphometric measurements were performed on 10 well-oriented and intact villi and 10 crypts chosen from each gut segment.…”
