{"title":"REPRODUCTIVE PERFORMANCE OF RAHMANY EWES FED BASAL RATION SUPPLEMENTED WITH DIFFERENT SOURCES OF ZINC","authors":"Ramadan Abo Elhaded, Tarek Eshmawy, mostafa Abd El Rahim, Dawlet El Kerdawy, M. Tawfeek","doi":"10.21608/jpd.2021.204352","DOIUrl":"https://doi.org/10.21608/jpd.2021.204352","url":null,"abstract":"The present study was designed to investigate, which source of added zinc (Zn) to the basal ration could optimize or increase the reproductive efficiency and maintain the health status of Rahmany ewes and their offspring. To achieve the objectives of the study, forty Rahmany ewes in the last two months of pregnancy with average body weight (49.980.64 kg) and 3 years old were used until two months after parturition. Animals were distributed into 4 groups (10 ewes in each). The first experimental group was used as a control and was fed a basal ration without zinc supplementation, and other three groups were fed a basal ration supplemented with 50 mg Zinc in the form of Zinc sulphate (Zn-S) or Zinc methionine (Zn-MS) or Nano -Zinc oxide (Nano-Zn) per kg concentrate feed mixture (CFM), respectively. The basal ration in this experiment consisted of 50% roughages (clover hay or Egyptian clover and rice straw) and 50% concentrates (CFM + barley grains). The basal ration was formulated to meet the nutritional requirements of pregnant ewes (NRC, 2007). The daily ration of each ewes consisted of one Kg CFM + 300 g barley grains + 4.0 Kg Egyptian clover (fresh) + 400 g rice straw. CFM contained: 38% yellow corn, 17% sunflower meal, 39.0 % wheat bran, 3.0 % molasses, %2.0 lime stone and 1.0 % table salt. The reproductive performance traits, some biochemical blood serum parameters, milk yield and milk composition of Rahmany ewes were used as indices for the study. Results of the study showed that chemical analysis of basal ration recorded: 2.471 kg DM; 15.2 % CP; 3.2 EE; 19.2 % CF; 9.6 % ash, 52.8 % NFE, 0.86% Ca, 0.40% P and 51mg Zn/ kg DM. Lambs weights at birth and at 15, 30, 45 and 60 days of age and placenta weights were significantly heavier (P < 0.05) with ewes fed 1000 ABO ELHADED et al. supplemental Zn-M or Nano-Zn than those fed the basal ration only (control) or those fed the supplemental Zn-S. Lambs of the control ewes recorded the lightest weights compared with other groups. Litter size and viability (%) of lambs were insignificantly better with the ewes fed supplemental Zn than those fed the basal ration without Zn supplementation (control). The serum total protein (TP) and globulin (Glob) were higher (P < 0.05) in ewes fed supplemental Zn than those fed the basal ration without Zn supplementation (control). The ALT activity level, also in blood serum tended to be higher (P < 0.05) at lambing and after 60 days from lambing in ewes fed supplemental Zn than those fed the control ration. The levels of serum AST, urea-N and creatinine showed insignificant difference among the ewes groups. All the determined blood serum components in all the ewes groups were within the normal range of healthy sheep. Zinc concentration in the blood tended to be the highest (P < 0.05) with ewes fed Nano-Zn and ZnM, indicating that Zn is more absorbed from the gastrointestinal tract when Zinc is in the form of Nano-Zn or ZnMethionine. Milk yield (kg) was greater (P<0.0","PeriodicalId":184675,"journal":{"name":"Journal of Productivity and Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125634909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results obtained were compared also with the control (with no supplemental LED light). The light intensities of LED light sources In addition to natural sunlight were: 30, 25 and 20 μmol m -2 s -1 . The four water flow rates were 20, 15, 10 and 5 l/h. Some properties of Thyme plant were determined as plant length (cm) and the dry weight) g) was measured after measuring fresh weight) g). Also the amount of Photosynthetic pigments and accumulation of essential oil in leaves were determined. The results showed that, the highest values recorded in thyme plant growth of fresh weight, dry weight and height were 28.7g, 8.4g and 36 cm respectively, at highest light intensity 30 μmol m -2 s -1 (L1.) and middle flow rate 10 l/h (F3.) the maximum amount of Photosynthetic pigments in leaves were at the middle light intensity 25 μmol m -2 s -1 (L2.) and middle flow rate 10 l/h (F3.) where chlorophyll A, B, total chlorophyll and carotenoids were 4.55,2,6.57 and 2.32 mg/g respectively. It is clearly observed that the highest accumulate of essential oil was4.66 % at the highest light intensity 30 μmol m -2 s -1 (L1.) and middle flow rate 10 l/h (F3.), when compared with the rest of treatments.

Wheat plant was used as an indicator to achieve this goal. After wheat sowing, soils were fertilized by K2SO4 at different rates of 0, 50, 100 and 150% of wheat’s fertilizer recommendation. The obtained results showed that increasing added K + concentrations led to increase the activity ratio of K + (ARK 0 ) and corresponding changes in labile K + (K) at equilibrium. The equilibrium activity ratio of K + (ARK 0 ) varied between 2.88 − 15.01 × 10 −3 (mol L −1 ) 0.5 in initial stage and 1.39 − 17.31 × 10 −3 (mol L −1 ) 0.5 in the last stage. The labile K + (KL) fraction ranged from 0.047 − 0.456 and 0.02 − 0.45 cmol kg −1 before sowing and at harvesting time of wheat plant, respectively. The potential buffering capacities of K + (PBCK) fluctuated from 16.3 − 30.4 and 11.9 − 29.9 cmol kg −1 (mol L −1 ) −0.5 before sowing and at harvesting stage of wheat plant. The free energy of K + exchange (−ΔG) ranged from −3.37 to −2.42 (kcal. mol −1 ) prior to cultivation to reach −3.79 to −2.34 (kcal. mol −1 ) at the end of cultivation period. In general, Silt, pH, EC, OM, Soluble K, NH4OAcK and HNO3K exhibited substantial correlations with KL, PBCK, ARK 0 , KG and ΔG, whereas pH had inverse correlation with mentioned parameters, except KG. Furthermore, a substantial correlation was observed between thermodynamic characteristics of K extracted by H2O, 1 M NH4OAc and 1M HNO3. Conclusively: from these results it could be concluded that, significant correlation of the tested thermodynamic parameters with physicochemical soil characteristics. Thus, the study contributed significantly to practical K + management by providing important information on K + dynamics in typical Egyptian soils.","PeriodicalId":184675,"journal":{"name":"Journal of Productivity and Development","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133498756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mites, especially Tetranycus urticae koch and the parasitic mites Varroa destructor Anderson and Trueman (Pasositic) are unique among arthropods in that it is resistant to a wide range of acaricides and insecticides. Therefore, propolis efficiency was tested as ethanol extract (polar), hexane extract (non-polar) against Eutetranychus africanus (Tucher) and nano-emulsion of propolis against Tetranychus urtica and V. destructor. The results showed that, at the LC50 and LC90 ethanol extract was more toxic to adult females of E. africanus than hexane extract. Adult females of T. urticae were susceptible to the nano-emulsion of propolis. The LC50 and The LC90 reached 4.10% and 41.12% to the nanoemulsion of propolis. The biological aspects of two species of mites (T. urticae and E. africanus) were more affected by the three forms of propolis. In the winter season, the efficiency percentage of nano-emulsion of propolis at 4% reached 100% compared to control. While, in the autumn season, the efficiency percentage reached 95.62% at the first spray and reached 94.85% through 15 days of the first spray compared to 54.16 in control experiment.
