Abstract This study aims to estimate the Most Probable Producing Ability (MPPA) values of semen quality in five Bali cattle bull that collected from January to October 2016 at Singosari AI Center. The semen quality parameter consists of semen volume (ml), motility (%), concentration (x106), and total sperm (x106/ml) observed in rainy and dry season. Data were analyzed using intraclass correlation to estimate the repeatability and MPPA values. The average of semen quality in rainy and dry seasons, respectively, in volume were 3.91-6.24 ml and 4.38-6.84 ml, motility was 46.31-70.00% and 48.26-70.45%, semen concentrations were 844.78-1059.02 × 106/ml and 1033.15-1260.16 × 106/ml, and total sperm were 3280.58-5964.50 × 106 and 4493.31-7206.96×106. In this study, dry season shows better semen quality parameter as well as the repeatability value, therefore the estimation of MPPA in dry season is more accurate compared to rainy season.

The Difference

A breeding programme, which spanned over four seasons (early dry, late dry, and early rainy, late rainy), was carried with one west African Dwarf (WAD) buck, one red sokoto (RS) buck, eight WAD does and eight RS does. The buck were subjected electrical stimulation wiht an electrd-ejaculator and their semen collected and analysed.Fertility rate was significant (P<0.05) higher in WAD than in RS in early dry season. There was no significant eason effect (P,0.05). of season on fertility of WAD. Fertility was least in the early dry season in RS and the difference from other season was significant (P,0.05). The effect of season on both semen volume and concentration was significant (P,0.05). There was a progressive increase in both parameter from early dry season to late rainy season. However, RS showed superiorityover WAD in both parameters in all the seasons. There were no significant effects of breeds or season on allother parameters studied. The indication is that both breeds could be used for all-year-round breeding with adequate feeding in the zone. However, for purpose of artificial insemination, RS bucks, which produce larger quatities of semen with higher concentration, should be preferred.

The research was aimed to determine the effect of season on feed quantity and quality, and growth performance of male Bali cattle fattened in smallholder farms. Observation from January to March for rainy season and June to August for dry season. Feed quantity and quality were observed covering all feedstuff used farmers in fattening. Cattle used for rainy season was 50 heads aged 1.5 – 4.0 years with initial body weight (BW) 188.03±31.85 kg. In dry season, observation was continued for the same cattle as many as 35 heads aged 2.0 – 4.5 years and initial BW was 261.80±38.46 kg. Data were analyzed by quantitative descriptiption for feed quantity and quality, while growth performance were analyzed by independent T-Test. Results of study showed the dominant type of feedstuff used during rainy and dry season were L.leucocephala (56.00 vs 33.14%), Zea mays fresh straw 18.44% (rainy season), natural grass (13.00 vs 22.25%), P.purpuroides (3.68 vs 3.99%) and G.sepium (1.36 vs 29.69%). Crude protein (CP) of L.leucocephala and G.sepium higher during the dry season, while S. grandiflora, natural grass, and P.purpuroides higher in rainy season. The DMD (%) of L. leucocephala and S. grandiflora in rainy and dry seasons were almost the same, but G.sepium had DMD higher in dry season. The OMD L.leucocephala and G. sepium higher during the dry season, while the S.grandiflora had higher during the rainy season. Natural grass and P.purpuroides had DMD and OMD higher during the rainy season. Dry matter intake (kg/head/day) of cattle during dry season was higher (P<0.01), but rainy season ADG and FCR was higher (P<0.01). It can be concluded the feed used by farmers during the rainy season was more varied, with better quality. As a result, the performance of Bali cattle fattened was higher in the rainy season than in the dry season.

The invertebrate colonization during decomposition of Eichhornia azurea was observed in a lateral lake in the mouth zone of Paranapanema River into Jurumirim Reservoir in two periods of the year. The litter bags method was used for measuring the decomposition rate as well as to evaluate the invertebrates colonization. Forty-two litter bags, measuring 15 × 20 cm in size and 2 mm mesh net, were incubated "in situ". Six litter bags (three for colonization and three for decomposition measurements) were removed after the 1st, 3rd, 7th, 14th, 28th, 56th and 72nd days of incubation. After each day, the material was carefully cleaned for detritus removal and invertebrate sampling. The biological material was fixed with 4% formaline and then sorted and identified. The remaining plant material was dried in an oven (at 60ºC) and weighed. A fast material loss occurred during the first 24 hours and the decomposition rate was higher during the rainy season than in the dry season. A peak on invertebrate density (110 ind.g.DW--1) on the remaining detritus of Eichhornia azurea was recorded in the 56th day of dry season, when the polyphenol concentration of plant detritus was 0.57 UDO.g.DW--1. In the rainy season, higher density was found in the 28th day of incubation, when the polyphenol concentration was 4.36 UDO.g.DW--1. Apparently, the reduction in the polyphenol concentration was followed by an increase in invertebrate densities. The majority of the species observed in the detritus belongs to the collector group that was dominant after the 7th and 14th days in the rainy and dry seasons, respectively.

<p>The phrase <em>cyanobacteria bloom</em> implies a transient condition in which one to few species dominates communities. In this paper we describe a condition in which the <em>bloom</em> is of multi-year duration consisting of different morphologies of a single cyanobacteria species. Lake Catemaco, Veracruz, México maintained a year-round massive (10<sup>8</sup> trichomes L<sup>-1</sup>) population of potentially toxin-producing cyanobacteria, <em>Cylindrospermopsis spp.</em> The trichomes are present as straight and coiled morphotypes.  The relative trichome morphology abundance varied with rainy (June – October) and dry seasons (November – May), but total trichome abundance did not vary.  Coiled trichomes and heterocytes (occurring only on coiled trichomes) were significantly more abundant, both absolutely and relatively, during the dry season. Both coiled trichome and heterocyte mean volumes were significantly smaller during the rainy season than during the dry season.  Biovolumes were largest in January when water temperature was 5º C cooler suggesting buoyancy as a morphology-determining factor. However, with a more than three-fold lower TIN concentration during the dry season, we hypothesized that the coiled morphotype became abundant primarily because it formed heterocytes, which the straight morphotype did not. Spatial trichome and heterocyte abundance differences were small among the 15 lake sites (average CV for all dates = 20%). However, there was a pattern of increased heterocyte and coiled trichome abundance from lake inflow, as a nitrogen source, to outflow during the rainy season. The total volume of heterocytes per litre of lake water increased progressively four-fold from a minimum early in the rainy season to a maximum at the end of the dry season. Morphological diversity, as seen in Lake Catemaco, can partially compensate for the lack of species diversity in determination of community structure.</p>

This study aimed to characterize the morphology of the vas deferens ofKinosteron scorpioides by macroscopic and microscopic analysis. Were used 20 adult male jurarás collected at regular intervals during the year and divided into four experimental groups in the rainy and dry seasons, being processed for light microscopy, scanning electron microscopy and transmission electron microscopy. Morphometry for tubular and luminal diameters and epithelial height were also performed. On rainy season, vas deferens presented pseudostratified epithelium with cylindrical cells, spermatozoids and milky fluid in the lumen, with cytoplasmic organelles and lipid vesicles. On dry season, epithelium was pseudostratified with cuboid cells, with cellular debris and no spermatozoids. There was significant variation (p<0,05) for morphometry of vas deferens, with lower values of tubular and luminal diameters on rainy season, and higher epithelial height on dry season.

Background: The people of Awka urban show an increasing trend of using well water resulting to unreliable and quality-compromised water supply. Aim: Effects of depth and seasons on the physicochemical and bacteriological quality of selected well water samples in Awka urban, Anambra State was conducted to determine their quality and suitability for domestic uses. A total of thirty shallow and deep well water samples were collected during the rainy and dry seasons. Methods: Physicochemical analysis was carried out using standard analytical methods. The total bacterial count was determined by dilution method. Results: Some of the physicochemical parameters (PH, dissolved oxygen, nitrate, cadmium, lead and arsenic) exceeded the World Health Organization maximum containment levels indicating that the samples were unfit for domestic uses. The bacterial counts ranged from 2.66 to 3.26 logcfu/ml during the rainy season and 2.54 to 3.20 logcfu/ml during the dry season. The total coliform counts also exceeded the W.H.O levels. Citrobacter freundii, Shigella flexneri, Serratia marcescens, Proteus vulgaris, Vibrio cholerae, Salmonella typhi, Pseudomonas aeruginosa, Escherichia coli and Bacillus subtilis were isolated during both seasons and identified using standard analytical procedures. The bacterium that had the highest frequency of occurrence during the rainy season was Citrobacter freundii (16.55%) while Salmonella typhi had the highest frequency of occurrence during the dry season (17.69%) respectively. Proteus vulgaris had the least frequency of occurrence 5.41% and 4.62% during the rainy and dry seasons respectively. The results were analyzed statistically using two-way analysis of variance. Higher bacterial counts were recorded in rainy season and shallow wells than dry season and deeper wells. Conclusion: The presence of these bacteria above admissible limits showed that the water lacked proper water management services and may be harmful to humans. There is therefore a need to monitor the well water quality by employing better sanitary practices and subjecting the waters through various forms of water treatments before use to help prevent disease outbreak.

Objective: This study set out to assess sex differences and seasonal variations in Pediatric Infectious Diseases (PID) admissions. Methods: One year retrospective study of PID admissions was conducted among children aged one month to 15 years. Relevant information retrieved from patients’ hospital records were dates of admission and discharge, age, sex, final PID diagnoses and outcome. Results: Of 1,035 patients’ records assessed, 603 (58.3%) were males and 432 (41.7%) females (p<0.001). Males in ages 1-12 and 13-59 months contributed largely to the gender difference. Over the 12 months period, PID admissions mean was 86.25±21.92, with rainy and dry seasons means of 92.57±20.7 and 77.4±20.9, respectively (p<0.001). Ages 13-19, 60-119 and ≥120 months had significantly higher admissions mean during the rainy season (p<0.001 in each group), while higher admissions occurred among ages 1-12months in dry season (p<0.001). Top six PID managed were malaria, gastroenteritis, pneumonia, septicemia, meningitis and typhoid, and males had higher incidence in all except for typhoid, with only malaria having significant difference (p<0.001). Malaria, septicemia and typhoid incidence were higher significantly during the rainy season, while gastroenteritis occurred more in the dry season. Overall fatality rate was 4.6%; females and males rates were 6.3% and 3.5%, respectively (p=0.661). Rainy and dry seasons mortality means were 5±1.77 and 2.6±0.8, respectively (p<0.001). Conclusion: Male children were more vulnerable to PID, with significant higher malaria incidence among them than females. PID incidence and mortality were significantly higher during the rainy season than dry. Malaria and gastroenteritis occurred significantly in rainy and dry seasons, respectively.

Cocoa is a sensitive plant to availability of soil water. The availability of water affects the formation of cocoa pods and beans. The aim of this research was to determine the genetic diversity and the influence of season on the diversity of cocoa beans quality as well as determining the pattern of genotype and season interaction on the quality of physical physiology of cacao beans. The research was conducted in Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, Jember during dry season (2015) and rainy season (2016). This study used a complete randomized block design 2 x 12 factorial and three replicates as blocks. The first factor was the season consisting of two levels namely, dry season and rainy season. The second factor was cocoa clones, TSH 858, KW 084, KEE 2, Sulawesi 1, Sulawesi 2, BAL 209, KW 215, JTC 5A, JTC 5B, KC 2, KKM 22,and KJ 2. Observation variables included pod diameter, pod length, pod weight, dry bean weight, number of good beans/pod, number of empty beans/pod, numberof beans, and number of pods/tree/season. Data was analyzed using ANOVA fixedfactor. The bean dry weight characteristics possesed a low genetic diversity (0.27%) whereas the physical quality character of other beans, i.e bean count had moderategenetic diversity (14.20%). Meanwhile, the real difference was shown on the dry weight of bean characteristics. The best dry bean weight was observed during the dry season. Clones KW 215 and Sulawesi 1 in the dry season was catego-rized in grade A, while the lowest quality JTC 5A with grade D. The interaction of genotype (clone) with the environment (season) resulted in a significant effect onpod diameter character, pod weight, bean count, dry bean weight, and numberof pods/tree. Based on the biplot AMMI graph it was known that the TSH 858 clone showed genetic stability in bean count character. As for the character ofthe number of pods/tree, clones KKM 22, BAL 209, and KW 084 had the stability of the number of pods in rainy and dry seasons. Clones KJ 2 and Sulawesi 2 showed season-specific in the dry season for the number of pods/tree characters.

Leaf beetles (Coleoptera: Chrysomelidae) constitute a family of abundant, diverse, and ecologically important herbivorous insects, due to their high specificity with host plants, a close association with vegetation and a great sensitivity to microclimatic variation (factors that are modified gradually during the rainy and dry seasons). Therefore, the effects of seasonality (rainy and dry seasons) and microclimate on the community attributes of chrysomelids were evaluated in a semideciduous tropical forest fragment of northeastern Mexico. Monthly sampling was conducted, between March 2016 and February 2017, with an entomological sweep net in 18 plots of 20 × 20 m, randomly distributed from 320 to 480 m a.s.l. Seven microclimatic variables were simultaneously recorded during each of the samplings, using a portable weather station. In total, 216 samples were collected at the end of the study, of which 2,103 specimens, six subfamilies, 46 genera, and 71 species were obtained. The subfamily Galerucinae had the highest number of specimens and species in the study area, followed by Cassidinae. Seasonality caused significant changes in the abundance and number of leaf beetle species: highest richness was recorded in the rainy season, with 60 species, while the highest diversity (lowest dominance and highest H’ index) was obtained in the dry season. Seasonal inventory completeness of leaf beetles approached (rainy season) or was higher (dry season) than 70%, while the faunistic similarity between seasons was 0.63%. The outlying mean index was significant in both seasons; of the seven microclimatic variables analyzed, only temperature, heat index, evapotranspiration and wind speed were significantly related to changes in abundance of Chrysomelidae. Association between microclimate and leaf beetles was higher in the dry season, with a difference in the value of importance of the abiotic variables. The results indicated that each species exhibited a different response pattern to the microclimate, depending on the season, which suggests that the species may exhibit modifications in their niche requirements according to abiotic conditions. However, the investigations must be replicated in other regions, in order to obtain a better characterization of the seasonal and microclimatic influence on the family Chrysomelidae.

(Effect of supplementation of vitamin E, Selenium and Zinc mineral against to nutrient consumption, production and quality cement simental cow)ABSTRACT. Simental bulls often experience a decline in production and semen quality in the rainy season, which have a higher humidity and high rainfall. This study aims to maintain nutrient consumption, production and semen quality Simental bulls during the rainy season through the supplementation of Vitamin E, Selenium and Zinc Minerals. The study was conducted in July-December 2012 at the Artificial Insemination Center (BIB) Unggaran. The research material used in this study were 12 males Simental cows BIB Unggaran grouped by age. The experimental design used in this study is a randomized block design (RBD) with 3 treatments T1 (ration + Vit. E), T2 (ration + Vit. E + Se), T3 (ration + Vit. E + Se + Zn) and 4 groups as replicates. Parameters measured were dry matter intake and nutrient consumption, production and semen quality. Cement production was measured from fresh semen volume during the study, whereas semen quality measured motility and concentration of spermatozoa from fresh semen. Data consumption of dry matter and nutrient intake obtained were processed using analysis of variance, followed by Duncan test. While data on production and semen quality were analyzed descriptively. The results showed that the combination of vitamin E supplementation, minerals Selenium and Zinc did not affect dry matter intake, total digestible nutriens and crude protein, but resulted in a decrease in the percentage of shelter, semen volume, sperm motility and concentration smaller than before treatment. Treatment T1, T2 and T3 resulted in a decrease in the number of shelter respectively 41,55%, 19,56% and 13,63% compared to before treatment, whereas a decrease in semen volume unchanged at 44,9 %, 43,7% and 40,99%. Sperm motility due to treatment T1, T2 and T3 respectively decreased by 55,87%, 22,10% and 13,63% compared to before treatment. In line with sperm motility, sperm concentration in treatment T , T2 and T3, respectively decreased by 49,16%, 22,85% and 14,88%. The conclusion is a combination of vitamin E supplementation, minerals Selenium and Zinc can prevent the decline in cement production, sperm motility and sperm concentration Simental bulls during the rainy season.
