  Background: One hundred and eight weaned NZW rabbits used to investigate the effect of using remnants of mint, fennel, basil and anise with or without probiotic to replace 50% from alfalfa hay in rabbit’s diets. This part of study had shown the effects of experimental diets on rabbit meat composition and its fatty and amino acids. Materials and Methods: The four remnants were obtained after oil extraction and were incorporated in rabbit diets, rabbits randomly assigned in to 9 experimental groups, the experimental period lasted for 8 weeks. Chemical composition, fatty and amino acids were analyzed. Results: Chemical composition of meat fed different experimental diets were in the normal structure in rabbit meat with slight differences among them. Data of fatty acids fractions observed that Poly Unsaturated Fatty Acids (PUFA) were the highest proportion of total fatty acid (41.90%) after that the percent of Saturated Fatty Acids (SFA) (40.39%) then the percent of Mono Unsaturated Fatty Acids (MUFA) (17.71%). The highest value of the total non-essential amino acids was found in anise and anise with probiotic treatment (67.65 and 67.49 g/100 g) treatment, whereas, the lowest value was found in control, fennel and fennel with probiotics (62.73, 62.13 and 62.13 g/100 g, respectively) treatment. Conclusion: Summing up, using of that medicinal plants remnant to replace 50% from alfalfa hay in rabbit diets did not have any adverse effects on chemical composition of rabbit meat and its fractions of fatty and amino acids.

  Objective: This study aimed to evaluate the effect of feeding different levels of dry Moringa oleifera leaves (DMOL) on nutrient digestibility, some blood constituents and performance of suckling buffalo calves. Materials and Methods: Thirty newborn buffalo calves were used in feeding trial through suckling period. Calves were suckled buffalo milk and fed calf starter and berseem hay ad libitum as control ration, while in the other tested rations 5, 10, 15 and 20% of calf starter was replaced by DMOL for R2, R3, R4 and R5, respectively. Results: Data indicated that, DMOL contained 28.00% Crude Protein (CP), 6.23% Ether Extract (EE), 15.39% Crude Fiber (CF), 41.95% NFE and 8.43% ash (on DM basis). Nutrient digestibility, nutritive values, weight gain, feed conversion and economic efficiency of tested ration were significantly (p<0.05) increased with increasing the level of DMOL in the rations up to 15% and decreased afterwards at 20% level, which was nearly similar to control ration. There were insignificant differences in blood total protein, globulin, creatinine and alanine aminotransferase (ALT) among experimental rations. While, values of albumin, urea and aspartate aminotransferase (AST) were significantly (p<0.05) different among tested rations. Conclusion: Results of the present study concluded that replacing up to 15% of calf starter by DMOL improved growth performance of suckling buffalo calves, if compared with replacing 20% and control group.

  Background and Objective: Fertigation provide efficient method for fertilizer and irrigation of water in order to evaluate some potassium sources on wheat (Giza 168) production in sandy soil at El-Sadat City, El-Menoufia Governorate, Egypt, amid the two winter seasons 2016/2017 and 2017/2018. Materials and Methods: A split-split plot design in a randomized complete block arrangement was used with 3 replications. The main plots were allocated to the 2 potassium sources (potassium sulfate and potassium chloride) 3 potassium rates (60, 120 and 180 kg ha–1 K2O beside one treatment without potassium fertilization) were devoted to sub-plot and three patterns (1, 2 weeks and 1 month) were devoted to sub-sub plot. Results: The results showed that potassium had essentially influenced the yield and yield components of wheat and potassium fertilizers such as K2SO4 and KCl improved the quantity and quality of wheat. These results suggest that potassium application at 180 kg ha–1 associated with one pattern under fertigation can be good for obtaining an optimum yield of wheat. Conclusion: From this study can be concluded that the potassium application influence at 180 kg ha–1 K2O gave highly yield and chemical constituents under fertigation.
