The present study was done in the laboratories of animal science department that belongs Sulaimani University. During June 2017 to February 2018, a total of (91) duck and (98) geese eggs were collecting from local farms in Sulaimani province to evaluate some external and internal traits. Eggs weighed individually by using electronic balance, and Egg length and breadth of each egg was measured by using digital Vernier caliper. after breaking the eggs, yolk, albumin and shell weight was recorded. Moreover, Yolk diameter was estimated. Mean, standard error, minimum and maximum of the external and internal traits for both species were calculated using the descriptive analysis of SPSS. Person’s coefficients of correlation (r) among egg weight, external and internal egg traits were estimated. From the correlation matrix, data were generated for the principal component analysis. Anti-image correlation, Kaiser-Meyer-Olkin measures of sampling adequacy rotation component matrix, and Bartlett’s test of Spherity were computed to test the validity of the of the factor analysis of the data sets. The result of principle component analysis of egg trait extracted two factors that can objectively be used to describe the interrupted in the original elven egg quality characteristics of duck and geese. Therefore, the use of two orthogonal egg quality factor (PC1 and PC2) extracts from principle component analysis could be more reliable inter predicting egg quality compared to the use of the original inter correlated egg quality. The two principle factor could use in a breeding program for the important of egg quality traits.

The aim of this study was to evaluate the effect of adding zeolite mineral in semen extender on rabbit sperm cryopreservation. Ten healthy, fertile rabbit bucks were used, and the ejaculates were obtained using an artificial vagina. Semen of all bucks were pooled and diluted in a tris-yolk fructose (TYF) extender supplemented with zeolite at concentration of 0 (control) and 1% (w/v) for a final sperm concentration of 25 x 106 sperm cells/ ml. Diluted semen was packed in straws (0.25 ml) and stored in liquid nitrogen (-196 °C) for one month. After thawing, semen of each treatment was evaluated for sperm quality parameters, including sperm progressive motility, livability, morphological abnormalities and plasma membrane integrity. Apoptosis and sperm ultrastructure were also examined. Total antioxidant capacity and lipid peroxidation markers were determined in extender after thawing. Results showed that zeolite had a positive effect (P < 0.05) on sperm characteristics (progressive motility, livability and membrane integrity) after equilibration period and post-thawing as compared with the control. Percentage of viable sperm increased (P < 0.05), while percentages of early apoptotic, apoptotic and necrotic sperm cells decreased (P < 0.05) in treatment of zeolite as compared to control. In contrary, total antioxidants capacity in extender decreased (P < 0.05) and malondialdhyde and H2O2 concentration increased (P < 0.05) in treatment of zeolite compared to control. In conclusion, addition of semen extender with zeolite improved post-thaw sperm quality of rabbit by enhancing sperm characteristics, reducing apoptosis and sperm damage occurring by cryopreservation.

This study aimed to evaluate the effects of parity order (PO) and live body weight (LBW) on reproductive, calving and blood parameters of Maghrabi She-camels during post-partum period in Egypt. Post-partum 28 she-camels were divided according to LBW into four categories {400-430 (n=7), >430-460 (n=7), >460-500 (n=6) and >500-560 (n=8) kg}, and according to parity to 1st–2nd (n=8), 4th (n=7) and 5th-6th (n=9). Results showed that number of estrus cases/animal, post-partum 1st estrus interval (PPFEI) and cervical length increased by increasing LBW >500 kg (P≥0.05). Cervical closure time (P≥0.05) and uterine involution (P<0.05) increased by increasing LBW >430 kg. Uterine horn thickness, uterine length, cervical diameter and plasma progesterone and estrogen were not affected significantly by LBW. Estrus cases (n)/animal, cervical closure time and uterine involution increased in multi-parous than in primi-parous (P≥0.05), while cervical length increased at 5-6 parity compared with 1-4 parity (P≥0.05). The PPFEI, uterine horn thickness, uterine length, and progesterone and estrogen concentrations showed inconsistent changes in different parities (P≥0.05). Placental weight with or without fluids and calf weight at birth were not affected by weight or parity. Concentration of total proteins and their fraction as well as albumin/globulin ratio in blood plasma was not affected by weight. Glucose level reduced (P<0.05), ALP activity decreased (P≥0.05) by increasing weight. In conclusion parity and live body weight showed inconsistent trend of changes on reproductive performance, calving performance and blood biochemicals and hormonal concentrations during post-partum period of maghrabian she-camel under the Egyptian condition.

Forty mature healthy Barki ewes at late pregnancy, aged 3 - 4 years and weighed 45.2 kg were randomly divided into 4 groups, to evaluate the effect of replacement of Berseem hay (BH) with dried leaves and stems of some halophytes and salt tolerant plants species on some hematological and immunologic indices. The 1st group (G1), fed the control diet while the 2nd (G2), 3rd (G3) and 4th (G4) groups, BH was replaced by Acacia saligna, Atriplex halimus and Cassava manihot esculenta, respectively. Blood samples were collected during suckling period at times 1st, 4th and 8th week from ewes for hematological and immunological analysis.Results showed that, the number of red blood cells, hemoglobin and hematocrit% decreased significantly in time from the 1st to both 4th and 8th weeks. Ewes in group 2 (G2) represented the highest significant values of mean corpuscular volume and mean corpuscular hemoglobin. The highest white blood cells count was in the 1st week. Blood ALPHA 1 % and ALPHA 2 % showed significant differences between groups and the times of treatments. Differences of GAMA GL %, complement 3 and 4 levels were significant between the three times of treatments. Differences of IgG level between groups and time of treatments were significant. In conclusion, the replacement of barseem hay with dried leaves and stems of Acasia, Atriplex and Cassava plants had no adverse side effects on the studied hematological and immunological indices of lactating Barki ewes.
