orty New Zealand white rabbits (NZW) male rabbits weighed 500+6 g were used in the present study to determine the effect of using residues prickly pear peels of a source of dietary feedstuffs on productive performance, digestibility, some blood constituents and Economic efficiency of rabbit. The animals were divided into four experimental groups of 10 rabbits each. The experimental diets replacing hay with prickly pear peels (ppps) at portion ( 0.0, ,25, 50 and 75%)) respectively. Results obtained could be summarized as follow: The final live body weight, total weight gain and performance index were significantly (p> 0.05) affected by experimental treatment groups. The highest (p> 0.05) values of live body weight, total weight gain and performance index were recorded by rabbits fed 75 % (ppps) Inclusion (1986.5g, 1489g and 73.30 %) followed by received Inclusion level 50 % (ppps) ( 1946.97g, 1416.37g and 68.31 %), respectively compared with the 25 % (ppps) ( 1836.97g, 1339.37g and 59.45 %) or control ( 1778.75g, 1283.45g and 53.74 %),respectively. Feed intake (g), protein intake, and digestible energy intake were significantly (p> 0.05) decreased with increasing (ppps) levels. Rabbits fed (ppps) (75%) diet recorded a significant bester feed conversion ratio (FCR) value followed by those of 50 %, 25 and control respectively. Digestibility coefficient and nutritive values (DM, CP, CF, TDN and DE) were significantly improved for rabbits fed diet contained (ppps) compared to those fed the control diet. Cecal PH value and NH3 -N concentrations were higher (p> 0.05) in the control group than those of the treatment groups. Concentration of TVFAS was lower in control whereas the highest was obtained by treatment 75 % of (ppps) (p> 0.05). Also inclusion of tested material significantly (p> 0.05) increased dressing percentage and carcass weight. Plasma concentrations of total proteins, albumin and globulin were increased (p> 0.05) whereas ALT, AST, total lipids, total cholesterol, HDL and LDL were decreased (p> 0.05) by treatments of (ppps). The best Economical efficiency and relative economical efficiency values were recorded with rabbits fed 75 % (ppps) inclusion followed by rabbits received 50 % and 25 % treatment of (ppps) respectively it could be concluded that replacing hay with prickly pear peels (ppps) at portion (25, 50 and 75%) into diets recorded the beneficial growth performance, nutrients digestibility, and the best Economical efficiency of NZW Rabbits.

rickly pear peels (PPPs) was evaluated for their chemical and nutritional composition as a natural feed resource for feeding ruminants in two experiments. Each experiment consisted of three rations. Concentrate feed mixture (CFM), berseem hay (BH), rice straw (RS) and PPPs were used for formulating the experimental rations (60% concentrate + 40% roughage). In the first experiment 25% or 50% of RS were replaced by PPPs. In the second experiment, the inclusion rates of PPPs were instead of 25% or 50% BH. Chemical composition and in vitro digestibility using DAISY II incubator were used for nutritive value prediction. The results indicated that PPPs had lower contents of CP (5.67%) and CF (10.63%) while; it had higher values of NFE (69.59%) and NSC (66.56%) when compared with other ingredients used. Prickly pear peels had the lowest values of NDF (13.67%); ADF (10.20%), ADL (2.49%), hemicellulose (3.47%) and lignin (0.74%) when compared with other ingredients, but had higher NDF-cell soluble (86.33%). The highest values of apparent dry matter digestibility (ADMD) and true dry matter digestibility (TDMD) were recorded with PPPs (90.22% and 91.46%), respectively when compared with other ingredients. The natural detergent fiber digestibility (NDFD) was higher than that in RS and CFM while, it is lower than that in BH. The prediction parameters of nutritive values from chemical analysis for TDN% and NEL, ME, NEM, NEG, and DE (Mcal /Lb of DM) of PPPs were significantly (p<0.05) higher than those of other ingredients and followed by CFM. The lowest values were recorded with BH and RS. Ration (3) in which PPPs replaced 50% of RS recorded the best values of NFE and NCF, but lowest values of ash and CF when compared with control ration and ration 25% RS with PPPs. Ration 3 had the lowest values of NDF, ADF, cellulose, hemicellulose and lignin, followed by ration (2). The highest values were recorded with control ration. The highest increase value of NDF-cell soluble (17.45%) was recorded with ration (3) while, the increase in ration (2) reached 9.21% when compared with control ration. The effect of inclusion different levels of PPPs instead of the same levels of RS showed significant (<0.05) increase of ADMD% with ration (3) followed by ration (2) while TDMD% was not significantly influenced by inclusion of PPPs. In the contrarily, the NDFD% was decreased. Ration (3) had the highest values of TDN%, DDM%, DMI%, NEL, ME, NEM, NEG, DE (Mcal /Lb. of DM) and GE (MJ/Kg DM) while control ration recorded the lowest values. The highest feed cost and price of TDN unit were recorded for the control ration. The highest decreasing price of TDN unit (9.09%) was obtained by ration (3). Inclusion of PPPs instead of BH decreased CP%, EE%, CF% and fiber fraction % of rations 5 and 6, while NFE%, NSC% and NDF-cell soluble % were increased. Concerning, DM digestibility determination, the highest value of TDMD% was obtained with ration 6 followed by ration 5. The predicted energy values were higher with ration 6 while it recorded the lowest valu...

This study evaluated the potential of low-glycoalkaloid potato haulm (LGPH) as a high-quality feed for ruminants. The low-glycoalkaloid potato plants were grown in a net house following standard agricultural practices. Dehaulming was performed a fortnight before the harvest of the tubers, as commercially practiced. Four healthy female lambs (aged 4 months) were employed in a 4×4 Latin square feeding experiment design. The lambs were fed with either a maintenance diet consisting of 73% roughage (control), or treatment diets with supplementation of 10% (P10), 15% (P15), and 20% (P20) LGPH on a dry matter (DM) basis for a period of 21 days, including 14 days of adaption and 7 days of sampling. Refusals and feces were collected for 6 days and pooled followed by a 24 h urine collection on the 7th day. On the 6th day, an hour after morning feeding, blood, and rumen liquid samples were collected. All the samples were analysed, and the data generated were analysed using ANOVA with diet and period as fixed effects and sheep as a random effect. Orthogonal contrasts were used to detect linear and quadratic effects of LGPH in the diet. Linear or polynomial equations were produced to extract the nutrient digestibility and metabolizable energy (ME) of LGPH. No toxicological clinical signs were observed, and the haematology profiles were normal throughout the trial. LGPH did not affect the daily intake of nutrients and energy. However, the apparent digestibility of DM, organic matter (OM), crude protein (CP), and gross energy increased (P= 0.01) linearly (P< 0.01) with supplementation of LGPH in the diet. The inclusion of LGPH had a quadratic effect on neutral detergent fiber (NDF) digestibility (P= 0.027), reaching a peak of 54.8 % at 12.3 % LGPH supplement on a DM basis. The N retention in lambs fed with the P20 diet was nearly twice that of the control diet (P= 0.032; 19.1 vs. 10.2 g/d). The computed digestibility values of DM, OM, CP, and NDF for LGPH were 76.1, 79.7, 84.2, and 72.1 %, respectively, and ME was 2.62 Mcal/kg DM. Conclusively, by significantly reducing the glycoalkaloids’ content in potato haulm, we can safely repurpose the currently wasted foliage as a new source of high-quality roughage feed for ruminants, equivalent to alfalfa hay, without imposing any additional environmental burden. However, further research is necessary to assess impact of LGPH on growth performance, and milk productivity before practical application on commercial farms.
