Background: Feeding unsaturated fatty acids sources in dairy cows is considered as a strategy to improve animal health during postpartum period and milk fatty acid profile. OBJECTIVES: This study aimed to investigate the effects of conjugated linoleic acid supplement and combination of sesame meal and oil on performance and milk fatty acid composition of dairy cows during transition period. MET...

AIM To estimate individual test day variability in yield and composition of Surti and Mehsani buffaloes milk at day 15 and 60 postpartum (pp). MATERIALS AND METHODS A total of 13 normally calved Surti and Mehsani buffaloes each maintained at Livestock Research Stations of Navsari and Sardarkrushinagar Dantiwada Agricultural Universities, respectively, were selected for the study. Milk sample ...

The objective of this study was to compare milk protein, amino acid and fatty acid content and composition among two breeds of river buffalo (Murrah and Nili-Ravi), and their hybrid F1 and F2 (crossbreeding with local swamp buffalo). The protein and fat content in milk from crossbreed F1 and F2 were significant higher than that of river buffalo, but the milk yield was still lower than Nili-Ravi...

The aim of this study was to use meta-analysis to identify the enteric methane (CH4) mitigation strategy that reduced CH4 emission without lowering production. To this end, a database initially developed was updated, compiling data from 61 publications (233 experiments) for various observations in dairy cattle on effects of hydrogen sink (H-sink), ionophore, lipid and conc...

the effect of feeding of soaked barley straw on milk production and composition and rumen characteristics was studied. the degradability of soaked barley straw (for 24, 48 and 72 hours) and unsoaked barley straws were studied in the first experiment. the unsoaked barley straw had more readily degraded fraction (a) than soaked straw treatments (p> 0.05). there was no significant difference betwe...

seventy six high and low producer cows were selected to determine the composition of theblood and milk parameters, and their interrelationships to determine the indices which could beuseful to improve the milk yield. the highest mean blood concentrations were found in highproducer cows. mean values for blood urea nitrogen (bun), serum protein (sptn), creatinine,triglycerides (tgs), cholesterol,...

Daily milk, fat and protein yield and amount of somatic cells in cow milk are very important factors that influence milk performance traits. An association between polymorphisms in the kappa casein (CSN3) gene and milk production, composition and technical properties has been previously reported; however, this type of information is not available for the bovine β-carotene oxygenase 2 (BCO2) gen...

To determine whether insulin exerts an effect on milk fat yield through the direct regulation of milk fat synthesis in the mammary gland, the hyperinsulinemic-euglycemic clamp procedure was performed in lactating goats in the present study. The effects of the hyperinsulinemic-euglycemic clamp on milk yield, milk composition, milk fatty acid yield and the expression levels of mRNAs of milk fat s...

Milk yield and its composition vary according to individual cows as well as to a variety of different environment conditions, such as temperature. Previous studies suggest that heat exerts considerable negative effects on milk production and its composition, especially during summer months. We investigate the production and fat composition of milk from individual dairy cows and develop a modell...

Today, researches have shown that the best and most effective way to reduce the incidence of disorders related to pesticides and prevent their transfer to the milk and other animal products is the application of adsorbents or bonding compounds. This study aimed to investigate the effects of different toxin adsorbents (Mycofix-Plus, Bio-Tox, Bio-Acid) on the amount of diazinon residues in grape ...
