22 Dec Alltech will produce its feed additive Optigen II in Australia for the first time with an expanded production facility in Forbes, New South Wales. The objective of this field trial was to determine the effect of a controlled- release urea product (Optigen, Alltech.

Optigwn J Anim Sci. In my review of data, I can only find two feed additives that conclusively show improvements in rumen microbial growth. Responses in commercial dairies of milk protein and fat to increased concentrations of methionine and lysine in metabolizable protein1.

The slow-release urea product was hand-weighed using a precision balance Ohaus, mod AS, Pine Brook, NJand was added top-dressed in equal proportions to the diet at time of feeding.

Non-Protein Nitrogen (NPN) Source for Ruminants – Optigen II

Within farm, all lactating cows were fed a single-formulation TMR. Methionine in metabolizable protein ranged from 2. The ratios of starch: In contrast, the urea combination for an S: Either a higher or lower S: Matching dietary protein to animal requirements is obvious but this means feeding different rations to groups of cattle at different levels of production.


View All Alltech Australia News. Does this mean that rations for lactating dairy cows should not contain more than Chromic oxide used as a source of chromium to estimate nutrient flow and coefficient of digestion was added to the diets 3.

Ruminal digestion of OM, starch and feed N were not affected by urea combination or S: Please enter the text in the box: F ratio in the diet was manipulated by replacing the steam-flaked corn grain by dried distillers grain with solubles DDGS and forage sudangrass hay and wheat straw to reach S: I would like to enquire about Alltech Australia.


Another alternative is to maximize the ruminal production of microbial protein. Ruminal pH was not affected by urea combination.

The statistical model for the trial was as follows: Use of distillers by-products in the beef cattle feeding industry. Mainly because of simplicity, many dairymen are not willing to follow this strategy and choose to feed one ration to allttech production groups.

Why are ruminal cellulolytic bacteria unable to digest cellulose at low pH? In the same manner, compared to the control diet, at an equal S: Relationship between the concentrations of crude protein and apparently digestible protein in forages.
