Production Performance of Small Ruminants Fed Pruning Fruits Trees by Products. 2- Effect of Treated Pruning Peach Trees by-Products on Growing Sheep.

Abstract

This experiment was conducted to study the effect of chemical and biological treatments of pruning peach trees by-products (PTBP) on chemical composition, degradability, cell wall constituents, digestibility and nutritive value and its feeding effect on productive performance of growing sheep. Thirty Ossimi lambs with average body weight 18.00±0.20 kg and 4 months old were used in this study for 120 days. Lambs were distributed into five similar groups (6 lambs each) and randomly assigned to five experimental rations. The five respective rations composed of concentrate feed mixture (CFM) + roughage (PTBP), the control ration (R1) contained untreated PTBP; (R2) treated PTBP withTrichoderma reesei; (R3) treated PTBP with Trichoderma viride;(R4) treated PTBP with Trichoderma reesei + Trichoderma viride and (R5) 3% urea treated PTBP. The DM, OM and CP disappearance and effective degradability (ED) va lues were in situ determined. The digestibility and nutritive values of experimental rations were determined using fifteen adult Ossimi rams. Rumen liquor and blood samples were collected at the end of collection period. The results showed that fractions of DM (a&b) and (ED) were significantly (P<0.05) increased with treated PTBP either with urea or fungi compared to control (untreated PTBP). The highest degradable values of DM, OM and CP were observed with R4. Nutrient digestibility and feeding values (TDN and DCP) were higher (P<0.05) for rations containing treated PTBP than control. The highest values of TDN and DCP were observed for R4. Digestibility of cell wall constituents (NDF, ADF, cellulose and hemicellulose) were improved by treatments. Concentrations of rumen parameters (NH3-N and TVFA's) were significantly increased by treatments. However, no significant differences were found in blood constituents (total protein, albumin, globulin, GOT, GPT and urea) among the different experimental groups. Blood constituents were generally normal in all experimental groups. Growth performance with respect to total body weight gain and average daily gain (ADG) were improved by biological treatments. The same trend was observed for feed conversion and economic efficiency and the best values were recoded with R4. It was concluded that inclusion of treated PTBP to rations of growing Ossimi lambs could improve their performance especially treatment of PTBP with fungi.

Utilization of Trimming Waste of Mandarin Trees as Feed for Small Ruminants 1: Palatability and Nutritive Value for Treated vs. Untreated Wastes and the Effect on Animal Immune Status

“…The increase in TDN% and DCP% by the present treatments may be attributed to increasing nutrients digestibility and also to the urea included in liquid 1168 feed treatments (Salman et al, 2011). Similar results were obtained by Khir, et al (2015) who reported that TDN and DCP of pruning peach trees by-products were improved by chemical or biological treatments compared with untreated roughage. (Kearl 1982).…”

“…in rams fed TWMT treated with or without biological additives. In general, the mean values of TVFA's concentration in this study were within the normal range obtained by some researcher ; Phillip et al, (2014), Khir, et al, (2015) and Mahrous et al,(2019) who found that the mean values of TVFA's concentration ranged from 9.8 to 17.81 meq/dL for lambs fed treated pruning fruits by products.…”

“…They found that the efficiency of DM degradability (EDMD %) was significantly higher for treated roughage than untreated one. Also, Khir et al (2015) found that the EDMD of pruning peach trees by-products, was significantly (P<0.05) increased with fungi treatment (49.35%) compared with the control (40.27%).…”

“…Increasing ADG reflected on total gain during all period, hence, TR recoded the highest value (P<0.05) compared to CR and UR. Increasing ADG for TR group may be due to many reasons such as improving digestion coefficient of CP, higher digested protein intake (g/d) which probably enhanced the utilization and the availability of essential nutrients especially protein (Kewan et al, 2019), increasing DMI (Khir, et al, 2015), presence of probiotic and amino acids of feed (Prado et al, 2015). Adding enzymes and some amino acids in diets based on grass pastures for lambs led to improvement in ADG (Prado et al, 2015).…”

“…So, researchers have attempted to use citrus residues for ruminant feeding (Fayed et al, 2009, Phillip et al, 2014, Galal et al, 2016and Mahrous et al, 2019. The utilization of crop residues has several advantages as follows: -Reduction of environmental pollution and consequently health hazards resulting of the burning of these residues (Khir, et al, 2015). -Reduction of feed cost and consequently increase the economic efficiency of livestock production (Borhami and Yacout, 2001).…”
