An experiment was conducted for 6 weeks, 36 male rats were divided into 6 groups (6 rats in each). G1 served as vehicle treated control, G2 received PP extract via gavage (50 mg/kg body weight (b.w.) daily). G3 received AFS via gavage (1 mg/kg b.w.) twice/week. G4 received AFS via gavage (2 mg/kg b.w.) twice/week. G5 received AFS twice/week (1 mg/kg b.w.) + (PP) extract daily (50 mg/kg b.w.). G6 received AFS twice/week (2 mg/kg b.w.) + (PP) extract daily (50 mg/kg b.w.). Liver enzymes (Alanine Amino Transferase (ALT), Aspartate Amino Transferase (AST), Alkaline Phosphatase (ALP)), Total Protein (TP), albumin and renal biochemical parameters (creatinine, urea and uric acid) were estimated in serum at 3rd and 6­­thweek post treatment , while pathological examination of liver and kidney was performed at the end of experiment. Result demonstrated that both aflatoxins administrated levels caused elevation in AST, ALT, ALP, creatinine, urea and uric acid and a decrease in TP and albumin in dose and time dependant manner, while synergistic administration of PP extract and AFS resulted in limitation of the negative effects of AFS on the tested parameters especially with low AFS dose and longer time. Pathological examination revealed that the severity of damage in liver and kidney correlated with aflatoxins, doses. While PP extract administration was able to protect liver and kidney against low AFS dose and minimize the damage of liver and kidney induced by high AFS dose.}, keywords = {Aflatoxin,pomegranate,Pathological examination,Liver enzymes and renal biochemical parameters}, url = {https://jappmu.journals.ekb.eg/article_86279.html}, eprint = {https://jappmu.journals.ekb.eg/article_86279_5ad004f919fdbdb70e0a52b58eec0f25.pdf} } @article { author = {Etman, K. and Zeid, A. and El-Monayer, T.}, title = {UTILIZATION FROM NEW NUTRITIONAL RESOURCES IN RUMENANT FEEDING: 1- EFFECT OF USING DRIED DISTILLERS GRAINS WITH SOLUBLES(DDGS) IN RATIONS FOR FATTENING FRIESIAN CALVES}, journal = {Journal of Animal and Poultry Production}, volume = {1}, number = {12}, pages = {659-668}, year = {2010}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3642}, eissn = {2090-3723}, doi = {10.21608/jappmu.2010.86281}, abstract = {Forty-five male Friesian calves averaging 309.86 kg live body weight (L.B.W.), were divided into three similar groups (15 in each) and used in feeding trial which lasted 172 days.

All animals offered rice straw at the rate of 1.0% of L.B.W., plus 2 kg berseem hay/day. In addition, three digestibility trials (3 calves in each) were conducted to determine the digestibility coefficients of all nutrients and feeding values of experimental rations. The results obtained showed significantly (P<0.05) higher digestibility coefficients  and nutritive value of ration C (containing 20% DDGS) than the control ration (ration A). Average daily gains were 0.898, 0.955 and 1.110 kg for animals fed rations A, B and C, respectively. Animals given ration C grew significantly(p<0.05) higher than those given ration A or B. Significant (P<0.05) improvements were recorded for animals fed ration C with respect to feed conversion efficiency expressed as kg, DM, TDN, SE or DCP/kg gain. Results of ruminal measurements of animals fed rations B and C containing 10% and 20% DDGS showed high pH, NH3-N and VFA's concentrations. At the same time, serum blood parameters (Total protein, albumin and globulin) showed similar trend.

The animals were randomly assigned using a complete randomize design to receive one of the three rations as following for 90 day. All animal fed concentrate feed mixture at rate of 2% of live body weight and had ad libitum access to Faba bean straw (G1), Chick-pea straw (G2) and Lentil straw (G3). At the middel of the experimental period, three digestion trails were carried out by using metabolic cages to determine nutrients digestibility, nitrogen balance and feeding values of experimental rations. Data obtained revealed that Lentil and Chick-pea straws were higher OM, CP and NFE content than faba bean straw. On the other hand, the same straws were less ash and crude fiber content compared to Faba bean straw. Ration containing Lentil straw and chick-pea straw had significantly higher (P<0.05) crude protein intake (CPI) and total digestible nutrients intake (TDNI) as well as digestible crude protein intake (DCPI). In addition to DM, CF and NFE digestibility for ration G3 were (P<0.05) higher than G1 and G2. Concerning the nutritive values as TDN and DCP the results showed that G3 was higher (P<0.05) than G1 and G2. Insignificant differences (P>0.05) were noticed in rumen  NH3-N after 6hrs feeding  and TVFA's concentration among the groups  at  times 0 and 3 hrs after feeding. While, values of  pH had significant higher in G3 after 3 and 6hrs feeding  than G1 and G2. Nitrogen balance data clearly indicated that N retention was higher (P<0.05) for G3 and G2 comparable G1. Significant (P<0.05) increase in blood total protein, albumin and globulin concentration was recorded for G3 and G2 compared to G1.  Lentil straw group (G3) had the highest total gain and average daily gain (ADG) being 16.0 kg and 178 gm, respectively, at the same time, feed conversion as kg DM/kg gain improved. While, Chick pea was more economic efficiency than Lentil straw (G3) and Faba bean straw (G1). However, ration containing Chick pea  straw had cheaper cost  for produce 1 kg gain than the others.

The 1st one was to evaluate the nutritional values of both kinds of silages using 6 adult rams in two digestion trials (3 in each).  The other comparative study was carried out in summer season using swing-over method to investigate productive performance of lactating buffaloes which fed rations containing either green corn stalks or rice straw silages. Eight lactating buffaloes average 500-600 kg body weight at 2nd to 5th parities were used after 8 weeks of calving. Animals were fed three tested rations, the control (CR) represented traditional summer rations which composed of 53% concentrate feed mixture (CFM), 20% berseem hay (BH) 27% rice straw (RS) and the 1st tested ration (TR1) contained 42% CFM, 43% RSS and 15% BH, while the 2nd tested ration (TR2) was CFM, CSS and BH to supply 42, 43 and 15% of the daily DM intake, respectively. The impact of ensiled corn stalks and rice straw and their utilization for animal feeding per feddan was also investigated. The two tested silages had a good fermentation quality as low values of pH, NH3-N (%of total N) and normal concentration of VFA's. Corn stalks silage (CSS) had a higher nutritive values as TDN%, DE and DCP%, compared to green rice straw silage (RSS). Single crossbred of maize crop (Sc10) produced the highest silage yield / fedden being 5.13, 0.35, 0.23 and 3.03 ton/ feddan DM, CP, DCP and TDN, respectively. Corresponding values with rice straw (Sakha 104 variety) silage were 2.4, 0.14, 0.10 and 1.15 tan/ feddan. No significant differences among tested rations for OM, EE and NFE digestibility, while the differences were significant (P<0.05) in CP and CF digestibility coefficients. TR2 had the highest values (P<0.05) in TDN and DE followed by TR1, while control ration showed the lowest values. On the contrary, CR showed significantly (P<0.05) the highest DCP value followed by TR1, while TR2 recorded the lowest value. No significant differences were observed for actual daily milk yield, while 7% FCM yield differed significantly (P<0.05) among the tested groups. In addition, there were significant differences in fat, lactose and total solids contents in milk, while no significant differences between groups on protein and SNF contents in milk. Buffaloes fed TR1 and TR2 recorded the best feed conversion compared with those fed CR. Daily feed cost decreased with including RSS and CSS in the 1st and 2nd tested rations by 14.44 and 6.95%, respectively. Also gross margin over feed cost for buffaloes fed TR1 and TR2 increased by 78.9 and 100.0 % compared with those fed CR. Economic efficiency improved by 34.10 and 35.23 % for groups fed rations containing RSS and CSS (TR1 and TR2, respectively) compared with feeding control ration. It could be concluded that inclusion of rice straw silage or corn stalks silage as a basal ration for lactating buffaloes in traditional summer rations led to reduce the amounts of CFM by about 20%, increased daily 7% FCM by 15.03 and 26.12% and improve economic efficiency, along with limiting the environmental pollution as a result of accumulation of rice straw or corn stalks in the fields or burning them.}, keywords = {Lactating buffaloes,green rice straw silage,green corn stalks silage,nutrients digestibility,milk production,economic efficiency}, url = {https://jappmu.journals.ekb.eg/article_86286.html}, eprint = {https://jappmu.journals.ekb.eg/article_86286_f09bd02a7fd6811dd7719ec0079c92f4.pdf} }
