In Presynch-Heatsynch group, two injections of PGF2α analogue were administered at 12 days apart (Day -14 and -2) with last injection two days before GnRH administration (Day 0). A third PGF2α alpha was given on day 7 followed by estradiol benzoate injection on day 8 and fixed time artificial insemination (FTAI) on day 10. In Heatsynch group, first two PGF2 alpha injections were not given; however, rest of the treatment was same. Frequent urination, vulvar swelling and bellowing were prominent estrus signs observed in all buffaloes of both groups at the time of FTAI. The study revealed significantly pronounced (p<0.01) cervico-vaginal mucus (CVM) discharge and high uterine tonicity in buffaloes that became pregnant (100.00 and 70.00 %) than those failed to become pregnant (60.00 and 20.00 %) in group I and II, respectively. Further, it was observed that none of the buffaloes that became pregnant had low uterine tonicity, whereas 40.00 and 55.55% buffaloes which failed to become pregnant showed low uterine tonicity on rectal examination. In conclusion, appearance of CVM at vulva and rectal finding of high uterine tonicity at the time of AI had positive influence on the pregnancy rates in buffaloes subjected to estradiol based synchronization protocols. Thus, successful pregnancy may be predicted if a buffalo shows above two estrus signs at the time of FTAI.","PeriodicalId":23078,"journal":{"name":"Theriogenology Insight - An International Journal of Reproduction in all Animals","volume":"36 1","pages":"199"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87157023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The level of dietary crude protein is the most nutritional factor that influence the milk urea nitrogen concentrations in lactating cows. Recent researches suggest that the milk urea nitrogen content depends mainly on the nitrogen/energy ratio in the diet, but other many factors may affect ureogenesis. Level and quality of protein contents, milk yield, season effects or lactation stage, parity and lactation number, weight and breed, feeding frequency and water intake are factors associated with the variation of milk urea concentration. Several studies have suggested that measuring milk urea nitrogen may serve as indicator to monitor nitrogen efficiency in dairy cows and to improve milk nitrogen production. However, the targeted milk urea nitrogen values for optimizing the nitrogen utilization efficiency are different from those required for milk protein production. Thus, an increase in milk protein production can be expected at milk urea nitrogen levels >11 mg/dL, while protein utilization efficiency is below this level (<11 mg/dL). Normal MUN values range from 10 to 14 mg/dL, but for many countries, the recommended milk urea nitrogen values for cow’s milk are ideally ranged from 10 to 16 mg/dL of milk. Finally, to ensure a balance between milk protein production and reducing urea nitrogen excretion in urine and milk, recent studies suggest to include 16.5% of crude protein supply in dairy cows diets.","PeriodicalId":23078,"journal":{"name":"Theriogenology Insight - An International Journal of Reproduction in all Animals","volume":"102 1","pages":"145"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85875994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a marker whether nutrition stores are adequate, leptin may act in concert with gonadotrophins and growth hormone axis for the initiation of complex phenomenon of puberty. The expression and secretion of leptin are correlated with body fat mass and are acutely affected by feed intake. Moreover, circulating leptin increases during pubertal development in rodents and domestic animals. Effects of leptin are mediated mainly via receptor activation of the JAK-STAT pathway; however, activation of alternative pathways, such as MAP kinase, has also been reported. Leptin helps in oocyte development and maturation .It also has angiogenic, immuno-modulatory and anti inflammatory activities helps in implantation and prevents embryo rejection by the maternal immune system, invasion of trophoblast and cause mammary growth development.","PeriodicalId":23078,"journal":{"name":"Theriogenology Insight - An International Journal of Reproduction in all Animals","volume":"1 1","pages":"113"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89284724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Screening was done on 100 randomly selected animals. A questionnaire was framed and completed with detailed management practices, including the risk factors like age, parity and lactation number along with the management practices. The samples were screened using Modified California Mastitis Test (MCMT), Somatic Cell Count (SCC). Management practices and detailed questionnaire revealed the high risk groups. The prevalence of clinical and subclinical practices was found to be 43% (SCM: 41% and CM: 2%). Further, the highest prevalence of sub clinical mastitis was found in cattle belonging to groups; 8 to 10 years age (40%); in 5th to 7th month lactation stage (36%) and 3rd to 6th parity (38.8%) whereas clinical mastitis showed highest prevalence in 2-7 year old (2.4%); 5th to 7th month lactation stage (4%) and 3rd to 4th parity (2.7%) groups. A significant (p<0.05) difference in Somatic Cell Counts (SCC) was observed between control and subclinical and clinical cases. MCMT proved to be an important screening test in the field conditions. Managemental practices and risk factors contribute to the occurrence of disease. Preventive and control measures need to be adopted strictly to reduce the disease in animals.","PeriodicalId":23078,"journal":{"name":"Theriogenology Insight - An International Journal of Reproduction in all Animals","volume":"19 1","pages":"5"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74970790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
