Effect of Using Prickly Pear as a Source of Dietary Feedstuffs on Productive Performance, Physiological Traits and Immune Response of Rabbit. 2- Prickly Pear Peels

Abstract

he present study aimed to determine the effects of using different level of prickly pear peels byproduct as an unconventional ingredient in the different of rabbits on productive performance, digestibility, some blood constituents, immune response, activity of certain digestive enzymes in pancreatic tissue and intestinal contents and economic of efficiency. Sixty weaned New Zealand White rabbits (NZW) male rabbits aged 35 days and weighed 600g ± 2.20 were equally and randomly divided into four groups (15 in each one). The experimental diets contained different levels of dried prickly pear peels (PPP) (0.0 control (C), 10, 20 and 30%), respectively. Results indicated that: The final live body weight, total weight gain and performance index were significantly (P<0.05) affected by PPP groups. The highest (P<0.05) values of live body weight, total weight gain and performance index were recorded by rabbits fed 30% PPP inclusion (2178g, 1577g and 74.59%) followed by received inclusion level of 20% PPP (2080g, 1482g and 66.45%), respectively compared with the 10% PPP (2000g, 1398g and 58.82%) or control (1990g, 1390g and 56.37%), respectively. Feed intake (g/ day), protein intake, and digestible energy intake were significantly (P≤0.05) decreased with increasing PPP levels. Rabbits fed PPP (30%) diet recorded a significant best FCR value followed by those of 20 and 10 % tested material, respectively. Digestibility coefficient and nutritive values (DM, CP, EE, CF, TDN, DCP and DE) were significantly improved for rabbits fed diet contained PPP compared to those fed the control diet. There were significant increases detected for plasma total protein, albumin and globulin while blood plasma of total lipids was significantly decreased by increasing PPP inclusion level compared to control groups. Liver function as AST and ALT activity were not affected by dietary treatments with supplementing PPP. Values of each of blood components including (red and white blood cells count) and hemoglobin were increased in rabbits fed diet contained PPP than those of the control, Also there is a significant increase in the activity of intestinal amylase, lipase and protease in rabbits compared to controls. Moreover the concentrations of IgG and IgM of rabbits were higher for rabbit supplemented with PPP than the control group. The best economical efficiency and relative economical efficiency values had been recorded with rabbits fed 30% PPP inclusion followed by rabbits received 20% and 10% treatment of PPP, respectively. It is concluded that supplemental dried prickly pear peels (PPP) at the rate of 30 or 20 % of the diet improved growth performance and health status of the NZW rabbits.

Effect of Prickly Pear Cactus Peel Supplementation on Milk Production, Nutrient Digestibility and Rumen Fermentation of Sheep and the Maternal Effects on Growth and Physiological Performance of Suckling Offspring

“…Serum levels of AST, ALT and the ratios between them were not affected in lambs suckling from ewes fed diets supplemented with PPCP, without any side effects on the metabolic activity of hepatic tissue. The obtained findings are in harmony with El-Neney et al [76], who found that AST and ALT activities were not affected by dietary treatments supplemented with PPCP. Moreover, lambs suckling from ewes fed diets supplemented with PPCP had lower (p = 0.001, 0.013) serum urea-N and creatinine compared to the untreated group, which led to improved renal function in the present study, which was clearly evident in the low blood urea and creatinine.…”

Influence of Feeding Quinoa (Chenopodium quinoa) Seeds and Prickly Pear Fruit (Opuntia ficus indica) Peel on the Immune Response and Resistance to Aeromonas sobria Infection in Nile Tilapia (Oreochromis niloticus)

“…Polysaccharides from different plants such as QU can enhance the transformation of lymphocytes and maintain their proliferation in immunosuppressed animals [79]. Our findings are supported by El-Neney et al [46], who reported that the application of different levels of dried PP peels in the diet of rabbits for 14 weeks increased the levels of blood components (RBC and WBC counts and the Hb content). The increase in Hb and WBCs in the supplemented groups could be attributed mainly to the anti-inflammatory and antioxidant activities of the PP peel [80].…”

“…QU seeds (El Mashrq Company, Cairo, Egypt) were powdered and added to the basal diets at the above-mentioned levels (10% and 20%). The present study was a feeding trial based on the inclusion of these supplements into the diet to improve the growth rate and immune response of the other creatures [45,46].…”

The By-Products of Prickly Pear Processing in Broiler Feed: Case of Dehydrated Husks and Cake

“…However, Moula et al [19] for a 5% and 10% incorporation of FB cladodes in the broiler feed, observed no signi cant effect on body weight and ADG, in contrast to Ragab [26] who found in Hy-Line W-36 cocks fed with FB envelopes, a non-signi cant effect on body weight at 70 days but a positive effect on ADG. As in quails, Ragab [21] found that the incorporation of 15% and 30% FB envelopes had no in uence on body weight and ADG, while in rabbits, Hassan et al [27] reported nal weights and ADG with a ration containing 25% and 50% FB envelopes, These results contradict those reported by El-Neney et al [28] who found that a 20% and 30% incorporation of FB envelopes resulted in a signi cant increase in live weight. In fattening sheep, Islam et al [29] and Aware et al [30] reported a positive effect on body weight with incorporation rates of 60% and 80%.…”

“…Throughout the rearing period, the substitution of maize and soybean meal by prickly pear husks and meals respectively had a signi cant effect on average daily intake and feed conversion of broilers for the 10% and 20% groups. For their part, Badr et al [20] observed in Cobb chickens fed rations containing 5%, 10% and 15% FB envelopes, average daily intakes, and lower consumption indices than for the control, as did El-Neney et al [28] for the incorporation of FB envelopes and Zeedan et al [31] for the incorporation of FB cladodes, and in rabbits at levels of 10%, 20%, and 30%.…”
