Abstract
Heat stress has a detrimental effect on animal fertility, particularly testicular functions, including reduced sperm output and quality, which causes an economic loss in the production of rabbits. The present trial investigated the efficacy of dietary Spirulina (SP) (Arthrospira platensis), selenium nanoparticles (SeNPs), and their combination (SP-SeNPs) on semen quality, haemato-biochemical, oxidative stress, immunity, and sperm quality of heat-stressed (HS) rabbit bucks. Sixty mature bucks (APRI line) were distributed into 6 groups of ten replicates under controlled conditions. Bucks in the 1st group (control-NC) were kept under normal conditions (11-22°C; 40-45% RH% = relative humidity), while the 2nd group (control-HS) was kept under heat stress conditions (32±0.50°C; 60-66% RH %). The control groups were fed a commercial pelleted diet and the other four heat-stressed groups were fed a commercial pelleted diet with 1 g SP, 25 mg SeNPs, 1 g SP+25 mg SeNPs, and 1 g SP+50 mg SeNPs per kg diet, respectively. The dietary inclusion of SP, SeNPs, and their combinations significantly increased hemoglobin, platelets, total serum protein, high-density lipoproteins, glutathione, glutathione peroxidase, superoxide dismutase, and seminal plasma testosterone while decreased triglycerides, total cholesterol, urea, creatinine, and malondialdehyde compared with the control-HS. Red blood cells, packed cell volume, serum albumin, and testosterone significantly increased, while SeNPs, SP+SeNPs25, and SP+SeNPs50 significantly decreased low-density lipoproteins, aspartate, and alanine amino transferees. Total antioxidant capacity substantially increased in serum and seminal plasma, while seminal plasma malondialdehyde decreased in 25 or 50 mg of SeNPs+SP/kg groups. All supplements significantly improved libido, sperm livability, concentration, intact acrosome, membrane integrity, total output in fresh semen, and sperm quality in cryopreserved semen. SP-SeNPs50 had higher synergistic effect than SP-SeNPs25 on most different variables studied. In conclusion, the dietary inclusion of SP plus SeNPs50 has a synergistic effect and is considered a suitable dietary supplement for improving reproductive efficiency, health, oxidative stress, and immunity of bucks in the breeding strategy under hot climates.

Abstract
The study evaluated the effect of housing system, insemination frequency, and sperm concentration on hatching traits of commercial broiler breeder. Experiment was set up as 2 × 4 × 4 factorial arrangement under completely randomized design. A total of 960 broiler breeder females (Ross-308) were divided evenly (480) into two groups for Artificial Insemination in cages (AIC) and on deep litter floor (AIF) with 41 and 48 males were allocated for aforesaid flocks, respectively. Females birds of both flocks (AIC and AIF) were further divided into 4 treatment groups to apply 4 various insemination frequencies at 4, 6, 8, and 10th days. These treated groups were further divided into 4 subgroups to apply each of insemination frequencies with 4 different sperm concentrations per insemination dose 100, 125, 150, and 175 × 106 sperms during peak phase of production which were replaced with 200, 225, 250, and 275 × 106 sperms in post peak phase. According to the results, significantly higher egg production, fertility, hatchability and number of chicks were documented when AI was conducted in cages as compared to deep litter floor. Although, the best reproductive performance was observed on 4 and 6th day insemination frequencies on all subjected sperm concentrations during peak; however, these parameters were found better on only 4th day during post peak. Sperms concentrations of 150, 175 × 106 during peak and 250 and 275 × 106 during post peak brought forth the best reproductive performance on all insemination frequencies. Although, embryonic mortality was significantly higher, when AI was conducted in floored flocks particularly when repeated after 4th day; however, various sperm concentrations found inert. In conclusion, AI found advantageous in caged flock as compared to floored. The consortium of different insemination frequencies and sperms concentrations are required for sustainable reproductive traits with progression of breeder age.

Abstract
The aim of the present study was to investigate the long-term effect of using bee venom (BV) on the reproductive performance, immune, and health status of rabbit does and its effect on their litters. Sixty mature does, from Spanish V-line rabbit stock, were randomly assigned to four homogeneous groups with 15 does each. The 1st , 2nd and 3rd groups were injected twice weekly under the neck skin with 0.1 ml solution contains 0.1, 0.2 and 0.3 mg BV/rabbit respectively. The 4th group served as a control group. From the results, litter size at birth, litter weight and survival rate at weaning age as well as milk yield were significantly (p ≤ 0.05) increased in BV groups than in the control group. Serum estradiol 17-β (E2) was significantly (p ≤ 0.05) higher (15%) in the rabbit does treated with BV compared to the control group. The treated does with BV at any study doses showed a gradual and significant (p ≤ 0.05) decrease (12%) in serum progesterone levels (P4) compared to the control. They also showed a significant (p≤0.05) increase in conception (17%) and fertility rates (10%) compared to the control does. Treatment of rabbit does with BV caused a gradual and significant (p ≤ 0.05) reduction in both aspartate aminotransferase (AST) (16%) and alanine aminotransferase (ALT) (37%) liver enzyme activities. Additionally, results have shown that BV resulted in a gradual and significant (p ≤ 0.05) increase in total antioxidant capacity (TAC), antioxidative enzymes such as glutathione S-transferase (GST) and glutathione peroxidase (GPx), serum IgG, IgM and IgA levels with significant (p ≤ 0.05) decrease in malondialdehyde (MDA) and thiobarbituric acid reactive substances (TBARS) in BV groups compared to the control group. Results suggest that BV can be used in rabbit farming as an effective and safe alternative to artificial chemical drugs (sexual-stimulants) to improve certain reproductive traits, immune response and health.
