This study was carried out to evaluate the seasonal variation on semen characteristics of Murrah buffalo bulls in Indonesia. A total of three Murrah buffalo bulls were included in this study. The semen was collected once a week during the rainy season (from January to April and from October to December) and the dry season (from May to September). Immediately after collection, the semen volume, sperm concentration, total sperm output, individual motility, post-thawing motility, and straw production were evaluated. The results showed that the season did not change (P0.05) the semen volume, individual motility, and post-thawing motility. However, sperm concentration, total sperm output, and straw production were decreased in the dry season (P0.05) as compared to the rainy season. In conclusion, several semen characteristics of Murrah buffalo bulls may vary depending on the season of collection. The semen collection during the rainy season is more profitable than the dry season.

This study investigated the influences of rainy and dry seasons on semen characteristics of fat-tailed and Garut rams under tropical conditions. A total of 4 healthy rams (2 fat-tailed rams and 2 Garut rams) aged 3 to 4 years old were used in this study. The semen was collected from each ram during November 2016 to February 2017 (rainy season) and May to August 2017 (dry season). The measurement of semen characteristics including semen volume (SV), sperm concentration (SpC), total sperm (TSp), individual sperm motility (ISM), post-thawing sperm motility (PTSM), and frozen semen production (FSP). The rainy season resulted higher SV (P= 0.021), TSp (P= 0.005), ISM (P= 0.028), and FSP (P= 0.005) than the dry season. On the other hand, fat-tailed rams had higher (P0.001) SV, TSp, and FSP compared to Garut rams. There was no interaction (P0.05) between season and breed on all semen characteristic parameters found in the present study. It can be concluded that the semen collection during the rainy season had a beneficial impact to produce high-quality semen for artificial insemination program than in the dry season. Fat-tailed rams have better semen characteristics compared to Garut rams.

Seasonal variation is one of the principal non-genetic factors influencing performance of poultry in tropical environment. This study was conducted to investigate influence of seasonal variation on egg production and incidence of mortality in intensively-reared non-descript Muscovy ducks in Nigeria. Egg production and incidence of mortality in sixty two (62) female Muscovy ducks was studied in a 12-month trial divided into two major seasons: wet (April - September) and dry (October - March) and four sub-seasons: early rainy season (April - June), late rainy season (July - September), early dry season (October - December) and late dry season (January - March). Student?s t-test and Completely Randomized Design was used to analyse seasonal and sub-seasonal effect on performance, respectively. Season and sub-season significantly (P < 0.05) affected egg production; higher egg production was recorded in wet season compared with dry season (16.18% vs. 1.32%). Among sub-seasons, highest egg production was recorded in late rainy season (20.92%) while the least (0.00%) was obtained in late dry season. Conversely, there was no significant (P > 0.05) effect of season and sub-season on mortality. It is evident that seasonal variation had no effect on incidence of mortality but significantly affected egg production of Muscovy duck and the adverse effect is more pronounced in dry season most especially in late dry season.

Ensuring a sustainable urban water supply for developing/low-income countries requires an understanding of the factors affecting water consumption and technical evidence of individual consumption which can be used to design an improved water demand projection. This paper compared dry and rainy season water sources available for consumption and the end-use volume by each person in the different income groups. The study used a questionnaire survey to gather household data for a total of 398 households, which was analysed to develop the relationship between per capita water consumption characteristics: Socio-economic status, demographics, water use behaviour around indoor and outdoor water use activities. In the per capita water consumption patterns of Freetown, a seasonal variation was found: In the rainy season, per capita water consumption was found to be about 7% higher than the consumption for the full sample, whilst in the dry season, per capita water consumption was almost 14% lower than the full survey. The statistical analysis of the data shows that the average per capita water consumption for both households increases with income for informal slum-, low-, middle- and high-income households without piped connection (73, 78, 94 and 112 L/capita/day) and with connection (91, 97, 113 and 133 L/capita/day), respectively. The collected data have been used to develop 20 statistical models using the multiple linear stepwise regression method for selecting the best predictor variable from the data set. It can be seen from the values that the strongest significant relationships of per capita consumption are with the number of occupants (R = −0.728) in the household and time spent to fetch water for use (R = −0.711). Furthermore, the results reveal that the highest fraction of end use is showering (18%), then bathing (16%), followed by toilet use (14%). This is not in agreement with many developing countries where toilet use represents the largest component of indoor end use.

Exposure Pathways

Sanitation infrastructure are not able to cope with the increasing population in low-income countries, which leaves populations exposed to faecal contamination from multiple pathways. This study evaluated public health risk (using SaniPath) in a low-income community during the dry season, to identify the dominant exposure pathways, and compare this data to existing data for the rainy season, questioning the assumption that risk of faecal contamination is higher in the rainy season. SaniPath was used to collect and assess exposure and environmental data, and to generate risk profiles for each pathway. In the dry season the highest exposure frequency was for bathing and street food, exposure frequency generally increased, and seasonal variation was found in five pathways. The highest hazards in the dry season were through contact with drains, soil, and street food. Seasonal variation was found in the contamination of open drains and street food, with higher levels of Escherichia coli (E. coli) in the dry season. Open drains were identified as the most dominant risk pathway in both seasons, but risk was higher in the dry season. This highlights the complex nature of seasonal variation of faecal risk, and questions the assumption that risk is higher in the rainy season.

Crossbred Hampshire–Duroc boars were compared to purebred Hampshire, Duroc and Landrace boars for seven semen characteristics and for reproductive performance under competitive double mating. A total of 14 boars were represented: three Hampshire–Duroc, three Hampshire, three Duroc and five Landrace. Significant breed of boar effects were observed on semen volume (P <.01), sperm concentration (P <.10), concentration score (P <.05), morphology score (P <.10), live–dead rate score (P <.05) and total semen score (P <.01). Landrace and Hampshire–Duroc boars produced more than twice the volume of semen produced by purebred Hampshires and Durocs. Hampshire, Duroc and Hampshire–Duroc boars had greater sperm concentrations and concentration scores than Landrace. Hampshire–Duroc boars ranked highest for morphology and total semen scores, but lowest for live–dead rate score. When double-mated to Landrace sows, breed of boar had no significant effect on conception rate but significantly affected (P <.05) percent of litter sired. Hampshire, Duroc and Hampshire–Duroc boars sired almost twice as many pigs as the Landrace.

The goal of this study was to evaluate and compare the semen characteristics, and testosterone concentration for three breeds raised under hot, desert conditions in Saudi Arabia. A total of 150 rams (Najdi, Naemi, and Harri) were used, aged 12, 18, 24, 30 and 36 months (ten rams from each breed in each age group). Body weight and testicular parameters were measured. In addition, testosterone concentration (TC), ejaculate volume (EV), sperm concentration (SC), total sperm output per ejaculate (TSO), live sperm percentage (LSP), sperm progressive motility (SPM) and sperm mass motility (SMM). The results show that TC and EV differed significantly (P less than 0.01) between breeds. At 36 months, semen characteristics (TSO, SMM and SPM) differed significantly among breeds. Naemi rams were superior to Najdi and Harri in terms of the mean live sperm percentage (LSP) for all age groups. These results may assist in ram selection for breeding programs based on high reproductive performance.

Abstract. Hafizuddin, Karja NWK, Praharani L, Setiadi MA. 2021. Breed and age effects on concentration of adiponectin and reproductive performance in Anglo Nubian, Etawah grade and its crossbred bucks. Biodiversitas 22: 1112-1119. The purpose of this study was to evaluate the effect of differences in breed and age on reproductive performance and adiponectin and testosterone production in Anglo Nubian, Etawah grade, and crossbred (Anpera) bucks. A total of 12 bucks with four individuals of each breed were used. This study collected five data points from each buck regarding adiponectin, testosterone, and reproductive performance (libido and semen characteristics). Data were analyzed with factorial analysis of variance and Duncan's test. The result shows that adiponectin concentration between breeds was significantly different (P <0.01). There were also significant differences (P<0.05) in adiponectin concentrations based on buck age. There were also significant interactions with adiponectin concentrations (P <0.01). Furthermore, testosterone concentrations showed significant differences based on breed (P <0.05) and age (P <0.05). There were also significant age-breed interactions affecting testosterone concentrations (P <0.01). Libido and semen characteristics had no significant differences based on breed and age group, and no significant age-breed interactions (P> 0.05). The heterosis effect on adiponectin concentration (48.05%), testosterone concentration (27.68%), libido (-0.61%), semen volume (-1.93%), sperm motility (0.49%), sperm normal morphology (0.18%), and sperm concentration (0.00%) was measured. In conclusion, there is a significant effect of breed, age, and age-breed interactions on the concentration of adiponectin and testosterone in bucks, and both of these variables have a high heterosis effect on crossbred bucks.
