“…Sperm concentration significantly (p<0.01) increased as the months moved from hot dry (75.72 -129.48 x 10 6 ) to cool wet season (98.17 -102.78 x 10 6 ). This result is consistent with an earlier report by Elagib et al (2012) that high temperatures reduced sperm concentration. Higher semen volume observed in the months of the hot dry season than in the cool wet season could be related to the increased spermatogenic activity of the testes.…”

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.

“…This is because during the rainy season, moringa leaf meal contained high levels of essential plant nutrients as compared to the dry season, hence when fed to birds there was high improvement in biochemical parameters. The results of this study corroborate with the findings of Elagib et al [42] who reported significant effect of season on albumin and cholesterol levels. Research conducted by Yokus et al [48]; Jesuyon and Salako [49] indicates that mean values for total protein, albumin, and globulin had been found to be significantly lower due to exposure of the animals to high ambient temperature thereby affecting the biochemical traits in birds.…”

“…This could be explained that moderate ambient temperature enhances maximum production of gonadotropin hormones which stimulate basophil production hence; this is possibly during the major rainy season where temperatures are relatively low as compared to the dry season. The results of this study corroborate with the findings of Elagib et al [42] who reported higher levels of epithelial cells and basophil in cold seasons as compared to the dry seasons.…”

This study was undertaken to determine the effect of moringa leaf meal and season on blood and hormonal profile of the Pearl Guinea fowl (Numida meleagris) in the Middle belt of Ghana. Thirty-two (32) males and one hundred and twenty-eight (128) female Pearl Guinea fowls aged one-day-old were used for the study. A 3 x 4 factorial experimental design was used for the experiment. Data collected were analyzed using General Linear Model (GLM) procedure of Statistical Analysis System (SAS for Windows, version 7) and means were separated by the probability of difference (PDIFF) procedure of SAS (2008). Mean cell volume was highest (175.39 fl) among Guinea fowls fed with diet containing 12 % moringa leaf meal level. Guinea fowls fed with diet containing 15 % moringa leaf meal had the highest (3.44 x1012/L) red blood cells production. Eosinophil level was highest (3.95 x1012/L) among Guinea fowls fed with diet containing 9 % moringa leaf meal. Birds fed with the moringa diets recorded the highest (P= 0.022) WBC values as compared to the control diet. Triglycerides, high density lipoprotein and low-density lipoprotein levels increased (P<0.05) with increasing levels of dietary moringa leaf meal in the diet. The highest (P= 0.0025) level of progesterone was observed among birds fed with diet containing 12 and 15 % moringa leaf meal inclusion levels. The level of sodium was highest (166.69 nmol/l) among Guinea fowls fed with diet containing 12 % moringa leaf meal. The major and minor rainy seasons recorded the highest (P<0.05) mean cell hemoglobin, red blood cells, albumin and oestrogen levels. Platelets, follicle stimulating hormone, luteinizing hormone, prolactin and chlorine levels were highest (P<0.05) in the dry season while basophil level was highest in the major rainy season. Cholesterol, triglycerides, high density lipoprotein, low density lipoprotein and potassium levels were highest (P<0.05) in the major rainy season. This study concludes that feeding Guinea fowls with moringa leaf meal had positive effect on some haematological, biochemical and hormonal parameters.

“…Semen of good quality, typified by the quality parameters of semen such as; volume, concentration, color, and motility, guarantees its usefulness in any AI program (Kotlowska et al, 2005). Although the quality of poultry semen can be influenced by a myriad of factors ranging from;age of the bird (Murugesan et al, 2012), breed/strain (Abas et al, 2018), temperature (Karaca et al, 2002), nutrition (Mahmood and Hazim, 2011;Hudson and Wilson, 2003), environmental conditions (Elagib et al, 2012;Santiago-Moreno et al, 2015), etc., it is pertinent to note that poor quality semen represents a great economic loss to production (Khatun et al, 2013). Hence, the need to improve and maintain a superior semen profile in any poultry AI program becomes imperative.…”

The effect of three strains of Lactobacillus based probiotics on the growth performance and semen quality of toms was conducted in a thirty-four week study. Eighty day-old (d 1) poults were randomly divided into 4 groups, replicated twice with 10 birds per replicate and assigned to four treatments; T1 (Lactobacillus delbrueckii subsp Bulgaricus), T2 (Lactobacillus acidophilus), T3 (Lactobacillus sporogens) and T4 (control), in a completely randomized design (CRD). Feed and water were supplied ad libitum. Results showed significant differences (P<0.05) in the birds' mean values for average daily weight gain, average daily feed intake, feed conversion ratio and final body weight. Birds on T2 had significantly (P<0.05) higher final body weight than other treatment groups. Toms on T4 had significantly (P<0.05) higher values for feed conversion ratio than birds on probiotic treatment with T2 recording the least value. However, the effect of treatments on the semen physical characteristics of the birds were also found to be significant (P<0.05). The birds on probiotic treatment recorded higher values for the semen quality indices under study than the control group, with T2 having the highest values. It was thus concluded that of the three strains of Lactobacillus based probiotics used in the current study, T2 (L. acidophilus) improved the growth performance and semen quality of local toms.
