I sent you two useful articles. If you want more details, please study Bovine Reproduction (2015)  and current therapy in large animal theriogenology (2007).

I thank you for your answer

Hi.

The area you asked is quite extensive. I am sending you two papers, might help. 

However there is plenty of literature on web of science or any other database. 

Wish you good luck,

thank you for the answer

Negetive energy balance have  severe effect due to metabolic as well as endocrine imbalance. It also presipitate many  production diseases

Dear,

negative energy balance is one of the most typical condition that hampers the all production performances in animals and reproduction is hampered last if it is prolong. for example, during the peri-parturition period, animals mostly suffers from this negative energy balance and this causes diseases like milk fever, metritis, laminitis, Retained placenta and so on. this may partially or completely impair the reproductive performances of the animals.

please find the following articles which are good in this topic

Reports indicated that negative energy balance can reduce progesterone secretion, prolong postpartum anestrus, and interfere with cow pregnancy. Negative energy balance in the early postpartum period affected follicular development. Moreover reduction in the body condition score during the transition period increased the incidence of postpartum reproductive disease and inactive ovaries.

Dear kahouli

Negative energy balance in fresh cows has severe effects on their performance, especially on reproduction. However there is plenty of literature on web of science or any other database. 

Regarding negative balance in dairy cattle nutrition,  lots of information are available in the Web and you can collect and pick up the scientific  message for your use.    

thank you verry much Mr Dhia Hussain
