Association Between Postpartum High B-Hydroxybutyrate and/or Non-Esterified Fatty Acids and Plasma Metabolites, Body Condition and Reproductive Performance in Dairy Cows-Juniper Publishers

Image
JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF DAIRY & VETERINARY SCIENCES Abstract The objectives were to assess post-partum blood non-esterified fatty acids (NEFA) and p hydroxybutyrate (BHBA), considered either together or separately, relative to plasma metabolites, body condition score (BCS), estrus cyclicity and first service pregnancyin 50 dairy cows sampled from 15 to 52 days in milk (DIM).The thresholds for high NEFA and BHBA were ≥0.70 Mm and ≥ 0.96mM at DIM 30, respectively. Cows with simultaneously high BHBA and NEFA have different plasma metabolite profile compared to cows with low BHBA or NEFA and, to a lesser extent, compared to cows with high NEFA only. The change in BCS from calving to DIM 52 showed a similar pattern, with a more intensive BCS decrease in cases of high BHBA and NEFA, although the difference from cows with high NEFA only was not significant. Compared to cows with low BHBA and low NEFA, the odds of estrus cyclicity at DIM 52 was 85% lo...

Study on Proteolytic Potential of Buffalo Milk Using Lactococcus Lactis Ssp. Cremoris and Lactococcus Lactis Ssp. Lactis-Juniper Publishers

Journal of Dairy & Veterinary Sciences - Juniper Publishers     Introduction Buffalo milk contains all the nutrients in higher proportions than cow milk as per the nutrient components. The compositional differences between buffalo and cow milk are reflected on their physico-chemical properties. Milk from buffalo preferred for preparing dairy products of western and traditional (indigenous) type and nutritionally superior. Buffalo milk contains less cholesterol (total cholesterol 275 mg and free cholesterol 212mg per 100g of fat) in compared to cow milk (total cholesterol 330 mg and free cholesterol 280mg per 100g of fat) and more tocopherol (334.21|ig per kg for buffalo and 312.3|ig per kg of cow milk). Due to high peroxidase activity, buffalo milk can be preserved naturally for a longer period. Buffalo milk contains more calcium, better calcium: phosphorous ratio and less sodium and potassium than cow milk which makes it ...

Impact of Subacute Ruminal Acidosis (SARA) on Ruminal Microbiome, Lipopolysaccharide and Bioamine and Rumen Epithelial Health of Dairy Cows - Juniper Publishers

Impact of Subacute Ruminal Acidosis (SARA) on Ruminal Microbiome, Lipopolysaccharide and Bioamine and Rumen Epithelial Health of Dairy Cows Authored by Shengyong Mao Maximizing milk yield without impairing host health is a great challenge for dairy industry. However, the high concentrate feeding often unavoidably increases the risk of Sub acuteruminal acidosis (SARA) in dairy cows, characterized by periodic episodes of low ruminal pH. The economic costs caused by SARA are enormous, while its pathogenesis is not very clear. As the first and the main digestive compartment, the rumen health during SARA has received much research effort in recent years. There are increasing evidences showing that the effects of SARA on rumen are multifaceted and detrimental. To address this issue, this review summarized the impact of SARA induced by high-concentrate feeding on gastrointestinal microbiota, ruminal fermentation, and its role in damage to the ruminal epithelium and host f...
