The Influence of Seasonal Variation on the Testosterone Hormone of Black Bengal Bucks (Capra aegagrus hircus)

The Black Bengal bucks of Indian sub-continent generally show a noted seasonal variation during in reproductive activity.India has a good number of Black Bengal goat populations, which has an important role in the lives of the goat rearers. The objective of thepresent study is to comprehendthe influence of seasonal variation on the testosterone hormone of Black Bengal bucks(Capra aegagrus hircus) in two different agro-climatic zones in India. The highest mean value oftemperature (42.6 ± 1.5 ºC) has been reported during the month of April or May in the season of pre-monsoonin Purulia. However, the lowest value of temperature (8.6 ± 0.9 ºC) has been reported during the month ofDecember or January in the season of post-monsoon again in Purulia.Serum testosterone was analyzed in blood samples collected once a week. It has been observed that, from January to April for both of the regions of Purulia and Nadia and the month May has the lowest serum testosterone level in Purulia (1. 22 ± 0. 18 ng/ml) and the serum testosterone levels stayed approximately the same from January to March in Purulia and more or less similar in Nadia.However, the serum testosterone level reached to its peak level in November in both the region Nadia (8.79 ± 1.3 ng/ml) and Purulia (6.59 ± 0.41ng/ml) respectively.It can also be presume that the early periods of the post-monsoon season can be taken as an alternate breeding seasons for Black Bengal breeds.<br

A Health GIS Based Approach to Portray the Influence of Ambient Temperature on Goat Health in Two Different Agro-Climatic Zones in West Bengal, India

<p>Abstract<br>The spatial and temporal distribution patterns of the livestock health status in the developing countries<br>like India are complex. In this regards, the application of Geographical Information System (GIS) is<br>valuable as it has many features that make it an ideal tool for use in animal health surveillance, monitoring,<br>prediction and its management strategy. The goal of the present study is to find out the effect of ambient<br>temperature on goat health in two different agro-climatic zones in West Bengal, India with the additional<br>help of GIS technology. The highest mean value of temperature (42.6 ± 1.5 ºC) has been reported during<br>the month of April or May in the season of pre-monsoon in Purulia. Survey of India (SOI) topographical<br>sheets (73 I/3 and 79 B/5) are used to map the study areas. Top sheets are scanned, geo-referenced and<br>then digitized with the help of GIS software. The biochemical and meteorological data are entered to the<br>newly prepared digitized map as the non-spatial data or attributes. Moreover, the present work aims to<br>confer an indication of the potential applications and usages of a GIS in the field of animal health for<br>advancing the knowledge about this innovative approach of goat heath surveillance and monitoring.<br>Keywords: Goats; GIS; Pre-Monsoon; Post-Monsoon; Purulia; Nadia.</p

The Influence of Ambient Temperature on Thyroid Activity, Erythrocytic Indices and Some Biochemical Parameters of Black Bengal Goats (Capra aegagrus hircus)

<p>Abstract<br>India has a good number of Black Bengal goat populations, which has an significant role in the lives<br>of local goat rearers. The aim of the present study is to find out the effects of changing seasons on thyroid activity, erithrocytic indices and some biochemical parameters of Black Bengal goat (Capra aegagrus hircus) in the presently studied agro-climatic zone in India. The highest mean value of temperature (42.6 ± 1.5 ºC) has been reported during the month of April and May in the season of pre-monsoon. However, the lowest value of temperature (8.6 ± 0.9 ºC) has been reported during the month of December and January in the season of post-monsoon. The parameter studied here are T3 and T4 hormones as well as blood pH, blood glucose level, concentration of Hb, RBC count, PCV, MCV, MCH and MCHC. Data has analyzed for the effect of seasonal variation and the current findings implies that seasonal variation plays the major role to influence the thyroid activity, erythrocytic indices as well as biochemical parameters of Black Bengal Goats.<br>Keywords: Goats; Pre-monsoon; Post-monsoon; Purulia.</p
