BACKGROUND The aims of the current study were to evaluate the inflammatory response in cow uterus and to explore the molecular mechanism triggered by high concentrate-induced subacute ruminal acidosis (SARA) in mid-lactating dairy cows. Twelve mid-lactating Holstein cows with an average weight of 455 kg were allocated into two groups subjected to two diets for 18-weeks either a low-concentrate ...

In this study, challenges experienced by dairy cattle enterprises in Southwestern Uganda and the factors influencing their profitability were respectively analyzed using exploratory factor analysis multiple regression STATA 15.0 statistical software. Eighteen questions relating to producers study area principal components with varimax rotation. Kaiser-Meyer-Olkin’s measure of sampling adequacy ...

the effect of barley grain processing and source of supplemental fat on performance of lactating dairy cows were studied in a replicated 4 × 4 latin square design with 21-d periods and a 2 × 2 factorial arrangement. eight holstein cows with mean body weight (bw) of 572 ± 71 kg and 45 ± 10 days in milk were allocated to 4 dietary treatments including 1) ground barley with cottonseed 2) pelleted ...

this study investigated the effect of rumex sc (commercial product which includes of saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). additionally, rumex sc was included in the experimental d...

I . The plasma levels of individual amino acids were studied in dairy cows under different conditions of production and energy nutrition. 2. A preliminary experiment was conducted which established that there was no regular change in amino acid levels with time of sampling in animals offered food twice daily at milking. 3. For animals in the 8th month of pregnancy plasma concentrations of lysin...

Twenty multiparous Holstein cows in midlactation grazed pastures of 4 forage mixtures in a 12-wk study repeated during 2 grazing seasons to determine if forage mixture complexity affected intake and productivity of lactating dairy cows. The forage mixtures were 1) orchardgrass plus white clover [2 species (SP)]; 2) orchardgrass, white clover, and chicory (3SP); 3) orchardgrass, tall fescue, per...

First cut red clover-grass mixture sward were ensiled in two pits with inoculant (Lactobacillus rhamnosus + Propionibacterium freudenreichii ssp. Shermanii) and without any additives. Fermentation quality, nutrient losses and aerobic stability of silages were determined. The inoculated silage had no butyric acid, nutrient losses were lowered by 19.4%. In inoculated silage organic matter digesti...

Milk yield greatly depends on mammary lactose synthesis due to its osmoregulatory property for mammary uptake of wate. A large amount of glucose is required by lactating dairy cows as the main precursor for lactose synthesis. Solute carriers (glucose transporters) in the bovine mammary gland play a key role in the transport of glucose and therefore milk synthesis. Different sugar transporters h...

Five multiparous, ruminally cannulated Holstein cows (two lactating and three dry) weighing (X +/- SD) 667 +/- 35 kg were used to study the effect of abomasal purine infusion on the excretion of purine derivatives. Cows were fed corn silage four times daily at 90% of ad libitum intake (X = 9.16 kg of dry matter/d). Purines were infused into the abomasum as brewer's yeast suspensions in five inc...

It was established by Shaw and Knodt (I) that the normal lactating udder (in situ) of the cow utilizes almost 2 mg. of phydroxybutyric acid per 100 ml. of blood traversing the udder; it was calculated that this was sufficient to account for the short chain fatty acids of milk fat or for about 40 per cent of the oxygen consumption of the secreting gland if it were oxidized for energy purposes. L...
