Mineral disorders can have a great impact on animal performance and to draw optimum production the deficiency gap needs to be abridged. Regular assessment of livestock visa -vis physiological demands and/or geo-climatic variations is an important management strategy to overcome severe economic losses. A study was undertaken to evaluate the plasma mineral profile of goats in Shuhama Alusteng area of Kashmir valley, aimed to set a platform for formulation of area-and species-specific mineral supplement(s). A total of 114 blood samples from goats belonging to different physiological states were collected in four different seasons of the year. The plasma macro-minerals like Ca, P and Mg were measured using standard kits, while micro-minerals like Cu, Zn and Fe were measured using atomic absorption spectrophotometer (AAS). Young stock revealed significantly higher Ca, but lower Mg status. Also, Ca level was lower throughout the year except autumn, whereas Mg was lower in winter and spring seasons. Cu and Zn concentrations, though adequate in all the categories, were near the critical values in spring and summer. Fe was adequate but could be provided during spring. Fe concentration observed was adequate-well above the critical concentration irrespective of the physiological status or season of the year. The study also revealed a good percentage of samples deficient in one or the other mineral throughout the year, suggesting Ca, Mg, Cu and Zn supplementation during specific periods. Further, formulating a mineral supplement(s) demands larger sampling size for confirmation of these findings besides the impact study of agro-geo-climatic conditions of the area on animal mineral status.

Evaluating mineral profile of sheep, belonging to different physiological states and in different seasons, is an important indicator of their nutritional and health status. This is important to prevent health disorders which lead to production and reproductive disturbances. A total of 167 blood samples were collected in four different seasons of the year from sheep having varied physiological demands in Shuhama Alusteng area of Kashmir valley. The plasma macro-minerals such as Ca, P i and Mg were measured using standard kits; while as micro-minerals like Cu, Zn and Fe were estimated using atomic absorption spectrometry. The concentration of Ca was below the critical level during pregnant and lactating periods, and round about the critical level throughout the year. The Mg values were just above the critical concentration in all categories of sheep throughout the year. The concentrations of Cu and Zn were above the critical levels in all categories of sheep especially during the winter season. P i and Fe levels were adequate in all throughout the year. In addition, a good percentage of samples were deficient in one or the other mineral round the year. The results suggest that sheep in the study area should be supplemented with Ca and Mg round the year; Cu and Zn during spring, summer and autumn seasons. Also, the influence of local agro-geo-climatic conditions plus mineral interactions involving greater sample size must be studied prior to attempting the formulation of area specific mineral supplement(s). Further, the dosage should be recommended as per the physiological need of an animal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
