The Affects of Nutrition on Reproductive Performance

Ramachandran Balagopal Good. The article has been dealt in crisp about the various nutrients essential for fertility. However if the values of requirement nutrients are tabulated it would be easy Veterinary Practitioners in the field to assess and analyze the the reason for the fertility problems.

I think this is one of the best pieces of information on the effect nutrition on reproductive performance in livestock. There is generally a paucity of information on the effect nutrition has on the reproductive performance and this is exacerbated by the uncoordinated and lack of interest of research in this field. In addition to the effect nutrition on dairy cattle heat manifestation, one area that has not been given emphasis is the effect of nutrition on embryonic/foetal survival. Generally dairy cows in negative energy balance would have high chances of embryonic death before day 18 even if they held service after insemination. The implication of this is that although an animal may manifest heat appropriately, the return rates will often be high as long as optimal nutritional is NOT maintained.

This article gives very useful information that how small nutritional deficiencies could create trouble and sometimes it is also misleading. Take for example, a deficiency in CP may not effect milk production but it can reduce fertility due to un detected heat. Good work and simple information for managers.

Good crisp information. Dairy business has become a tight rope walking with the cost of feed increasing on one hand & the production going down on the other so dairy mangers could take tips from this article.

This article justifies the role of energy for reproductive performance.But focus is not given on hormonal imbalance,which is also responsible for low reproductive performance.

Components of profitability in dairy production are milk and off springs. among offsprings heifers are more important as they will be future mothers of the herd. To me reproduction is more important than milk and to achieve the objective the herd must be regular calver. The article has addressed the issue vry nicely. Congratulations to team for their effort in this subject

The article is a good recollection of informattion regarding nutrient importance for reproduction but the daily requirement of the said nutrients are not specified in the article. It would be a beneficial effort if the quantity of these nutrients are also elaborated.However it is an appreciable article
