Effect of Propolis and Zinc Methionine Supplementation on Improvement of Productive, Reproductive and Immunity Performance of Local Developed Insash Strain Under Egyptian Summer Conditions.

Abstract

The objective of this study was to evaluate the impact of propolis and zinc methionine (Zn-Met) supplementation on improvement of productive, reproductive and immunity performance of local developed Insash strain under Egyptian summer conditions. A total number of 180 laying hens and 36 cocks of Inshas chicken at 24 weeks of age was used and divided into equal 6 experimental groups (30 hens + 6 cocks), each of three replicates (10 hens +2 cock in each replicate). The obtained results revealed a significant (P<0.05) improvement in egg production percentage, egg mass and feed conversion ratio in the groups fed propolis at the level of 100 or 300 mg plus 80 mg Zn-Met or at 300 mg propolis only /kg diet as compared with the control group. Percentage of fertile eggs, serum ALT, dead spermatozoa, sperm abnormalities, were significantly improved at the level of 100 or 300 mg propolis either alone or plus 80 mg Zn-Met /kg diet. While, percentage of hatchability, sperm motility, sperm cell concentration, were significantly increased in the group received 300 mg propolis only or plus 80 mg Zn-Met /kg diet. Serum total protein, globulin and cholesterol, acrosomal damage, immune response after injection of phytohemoaglutinine (PHA-P), serum IgG and IgM esteems were significantly (P<0.05) enhanced in all supplemented groups compared with the contrasted control. Digestibility coefficients of dry matter (DM), crude protein (CP) and organic matter (OM) were significantly (P<0.05) improved at the level of 100 or 300 mg propolis plus 80 mg Zn-Met /kg diet or at 300 mg propolis /kg diet alone, while AST and ether extract (EE) were significantly (P<0.05) improved at the level of 300 mg propolis /kg diet.Therefore, it could be concluded that, supplementation of 300 mg propolis either single or plus 80 Zn-Met /kg diet is recommended for improving most of productive and reproductive, traits including egg production, semen quality, fertility, hatchability and serum biochemical traits as wellas immune response.

Effect of Protected Methionine Supplementation on Body Weight, Testicular Parameters, Semen Characteristics and Testosterone Hormone of Awassi Ram Lambs

“…Although there was no significant effect of protected methionine but it was slightly improvement in this semen characteristics in treatment group than control group. This results agree with Ezzat et al (2019) which found an un significant improvement in semen volume, concentration, individual motility but the researcher get un significant decrease in dead and total abnormal sperms in treatment group than control in male laying hens supplemented with zinc methionine than control group, also result in agreement with Nizza et al (2000) which found un significant effect of methionine supplementation on evaluations of for volume, concentration, and little variation in motility and live spermatozoa percentage. But the results in contrast with Hong et al (2018) which found a significant effect of methionine supplementation in ration on semen concentration, individual motility, live sperms and significant decreased in abnormal sperms percentage on boar, also our results contrast with El-Sharawy et al (2012) which he found a significant effect of drenched zinc methionine on semen parameters of crossbred Rams.…”

Does the addition of choline and/or betaine to diets reduce the methionine requirements of laying quails? Assessment of performance and egg antioxidant capacity

“… Khairani et al (2016) clarified that the eggshell weight and thickness were unaffected by the addition of choline to diets with various levels of methionine, whereas previous authors pointed out an increase in the eggshell thickness ( Jalal and Al-Neemi, 2017 ) and eggshell relative weight ( Kiran et al, 2013 ; Jalal and Al-Neemi, 2017 ) when choline was added. For betaine, Sadegheymojarad et al (2018) in quails and Ezzat et al (2011) in hens noted that the addition of betaine did not affect eggshell parameters. Park and Ryu (2011) observed that adding betaine to diets containing various levels of methionine did not affect the eggshell-breaking strength and eggshell thickness in laying hens.…”

Dietary Addition of Betaine on the Performance of Broilers Fed with Diets with a Reduction in Methionine and Choline

“…Ratriyanto et al [35] reported increased crude protein and fiber digestibility at 0.06% and 0.12% doses. The dietary addition of betaine improved the digestion of crude protein and ether extract in laying chickens [36]. Increased digestibility of crude protein, crude fiber, and ether extract may have contributed to the increased body weight gain in groups PC and T1.…”
