“…Similar trends of monthly differences in semen volume have also been reported by Boland et al (1985). Similarly, Obidi et al (2008) reported semen volume decreased during the hot dry period of the year which normally occurs within the months of March to May; and a rapid increase in semen volume from the months of June to August has also been reported by Tharwat et al (1994).…”

The experiment was carried out to investigate the effect of season and graded vitamin C levels on semen quality of rabbit bucks in the Northern Guinea Savanna of Nigeria. A total of 55 rabbit bucks consisting of 40 pure New Zealand White (NZW) and 15 New Zealand x California (NZW×CAL) crossbreds were used for the study. The duration of the study spanned the hot dry (March-May) and cool wet (June-August) seasons. The traits investigated were semen motility, concentration, volume, pH, colour, live and dead sperm. Results obtained showed that vitamin C had significant (p<0.01) effect on semen characteristics. There was a progressive increase in semen motility, concentration and live sperm and decrease in dead sperm as vitamin C level increased. Semen volume deviated from this pattern while colour was consistent all through. The result on monthly variation indicated that volume increased during the months of March to May ranging between 1.32-1.43 ml while during the months of June to August, it oscillated between 0.41 - 0.95 ml. Sperm concentration significantly (p<0.05) increased from the hot dry months (75.72-129.48x106) to the cool wet months (98.17-102.78x106) while colour remained consistent with an increase in live sperm cells. There was significant (p<0.001) interaction between vitamin C level and season on sperm motility, concentration and live sperm being better in the hot dry (70.9%, 114.5x106, 85.31%) and cool wet (76.3%, 121.6x106, 90.14%) seasons on 400 mg/kg feed vitamin C. Sperm volume was higher on 100 mg/kg feed vitamin C in the hot dry (1.60 ml) and cool wet (0.98 ml) seasons and 400 mg/kg feed in the hot dry (1.57 ml) and cool wet (0.77 ml) than other levels. Based on the results, it is concluded that vitamin C improved the semen characteristics of rabbit bucks at 400 mg/kg feed during the hot dry season which translates to improved semen quality.

“…In the present study, the percentage of abnormal spermatozoa was very low, 1% in both seasons, and it was lower than that found by Machebe & Ezekwe (2002), who reported about 10% abnormalities in three genotypes of local breeds of roosters in the Spring of a tropical region in Nigeria. In another study, Obidi et al (2008) reported 7.8% abnormal spermatozoa in Shikabrown line roosters evaluated during the Spring in Nigeria. Tabatabaei et al (2009) reported a lower percentage of abnormal spermatozoa in local breeds (7%) than in Ross 308 roosters (10%).…”

“…On the other hand, there is evidence that higher relative humidity improves the reproductive performance of local breeds (Obidi et al, 2008). Therefore, environmental temperature and relative humidity are important factors influencing the reproductive performance of roosters; however, knowledge of the effects of these factors, especially in Mexican Creole roosters, is scarce and they need to be further investigated (Balnave, 2004).…”

“…This quality can be assessed according to variables such as pH, appearance, volume, mass motility, viability, morphology, and sperm-cell concentration (Elagib et al, 2012;Shanmugam, et al, 2012;Adamu et al, 2019). Furthermore, semen quality depends on bird genotype (Adamu et al, 2019;Tabatabaei et al, 2009), age (Juárez-Caratachea et al, 2018), and season (Bah et al, 2001;Obidi et al, 2008).…”

The objective of this study was to evaluate the effect of the seasons (Summer and Autumn), on live weight, body condition, mass motility, percentage of live spermatozoa, and sperm-cell concentration of Creole roosters (Gallus domesticus) from Mexico. Semen from 35-week-old Creole roosters was collected weekly during 10 weeks in Summer and Autumn, through the dorso-abdominal massage technique. Roosters were individually kept under a constant photoperiod (16 hours light:8 hours dark). The average live weight was 4.5% higher (p<0.05) in Autumn (2.78 kg) than in Summer (2.66 kg), therefore this variable increased with age (r = 0.85, p<0.05). Category 2 of body condition occurred (p<0.05) with higher probability than the others (0, 1 and 3), being practically the same (p>0.05) in Autumn (99.96%) and in Summer (99.81%). On average (and in weeks 1 and 3-10), the percentage of live spermatozoa was higher in Summer than in Autumn. Accordingly, the percentage of live spermatozoa decreased with age (r = -0.82, p<0.05). However, on average, sperm-cell concentration did not change between seasons (p>0.05). In conclusion, Mexican Creole roosters showed higher percentage of live spermatozoa in Summer than in Autumn. Therefore, it is advisable to select these animals of about 2.7 kg and reproduce them in Summer.

Probiotics are live cultures of microorganisms administered orally and acted beneficially on host health. The addition of probiotics to the diet of poultry has been found to improve growth performance, feed conversion efficiency, immune responses and help in combating enteric pathogens. Therefore, this study was carried out to determine the role of probiotics for preventing Salmonella Enteritidis infection and its effect on the performance as well as the immune response of broiler chickens. The studied Salmonella Enteritidis isolate was isolated from chickens from Qena Provence, Upper Egypt. One hundred and thirty, one day old Ross broiler chicks were divided into four equal groups; the first group (G1) was fed on a balanced ration and considered a negative control group.The second group (G2) was fed on a balanced ration and provided with the probiotic (Micro-Procell, cheil-Bio.com. LTD) containing Lactobacillus Plantarum 1×10 8 cfu, Lactobacillus Acidophilus 1×10 8 cfu and Saccharomyces Cerevisiae1×10 7 cfu, in drinking water for 5 successive days. The third group (G3) was challenged with Salmonella Enteritidis 10 9 Cfu / ml after Probiotics treatment and the fourth group (G4) was challenged with Salmonella Enteritidis 10 9 Cfu / ml at 6 days old and considered the positive control group. All groups were kept under complete observation for 4 weeks. Throughout the time of the experiment, both clinical signs and post mortum lesions were recorded for all groups, body weight (BW), food conversion ratio (FCR), total bacterial count, differential leucocytic count, phagocytic activity, serum biochemical parameters and humoral immunity (IgG and IgM) using ELISA technique were investigated. Results revealed high performance parameters, as an increase in body weight and FCR. Neither clinical signs nor PM appeared in both non infected group and the probiotics treated groups. The infected, probiotic treated group showed mild decrease in the performance parameters and mild degree of clinical sings and PM lesions for Salmonella Enteritidis infections. While the infected non probiotics treated group showed significant decrease in body weight, low of the performance parameters and characteristics sings and pm lesions for Salmonella Enteritidis infections along the experiment. Total bacterial count were decreased in infected treated group than infected one, differential leucocytic count showed increase monocyte and lymphocyte in propiotic treated group also the immune status assessment clarified that both phagocytic percentage and index significantly increased (P≤0.
