The objective of this study was to investigate the effect of a partial substitution of soybean meal with field pea (Pisum sativum) in Holstein lactating dairy cow diets on dry matter intake, milk yield and composition, blood metabolites, rumen ammonia-N concentration and pH. Eighteen lactating Holstein cows were randomly assigned into three groups based on parity, days in milk, and mil...

ABSTRACT: Acidophilus milk after preparation, with the defined characteristics of pH, titratable acidity and viable counts of Lb. acidophilus, was kept at the refrigerator (5 °C) and changes of above mentioned parameters were evaluated during 21 days at 7-day intervals. The obtained results showed that the titratable acidity of product significantly (p≤0.05) increased over storage period, demon...

this research with the aims of microbial flora determination in pasteurized milk and it’s shelf life study based on microbial and physicochemical parameters were performed within 10 days. in this study, 60 pasteurized milk samples randomly were selected and then total count of bacteria and total psychrophilic bacteria count were performed. to investigate microbial flora of pasteurized milk, col...

Cow milk, a highly nutritious food item, is amenable to quality degradation due to lipolysis and proteolysis, as a sequel to the growth of spoilage microorganisms, particularly under ambient condition in tropical countries, with consequential loss of aesthetic appeal and product output. Prescription antibiotics used for milk preservation have many undesirable side effects on the health of consu...

in order to surveying the effect of feeding propolis on performance, feed intake and digestibility in holstein suckling calves, the experiment was designed in a completely randomized design with 4 treatments (diet) and 10 replicates (cattle) during 52 days. treatments included: 1. control (without monensin in starter and without propolis in milk); 2. starter without monensin and 500 ppm soluble...

The objectives of this study were to estimate genetic correlations among body condition score (BCS), dairy form, milk yield, and days open in US Holsteins and investigate the potential of using BCS or dairy form evaluations as early indicators of days open. Dairy form and BCS obtained from the Holstein Association USA, Inc., were merged with mature equivalents (ME) for milk yields and days open...
