The present invention aims to provide feedstuffs for ruminants with high nutritional value and high digestion efficiency. According to the present invention, feed pellets for ruminants containing a kraft pulp derived from a lignocellulosic material are provided, wherein the kraft pulp has a Canadian standard freeness of less than 400 ml.

Feed pellets for ruminants

The present invention aims to provide feedstuffs for ruminants with high nutritional value capable of promoting rumination. According to the present invention, feedstuffs for ruminants containing a kraft pulp derived from a lignocellulosic material are provided, wherein the kraft pulp has a Canadian standard freeness of 400 ml or more.

Feedstuffs for ruminants

An electrolysis method of preventing the voltage of an electrolytic bath from rising over time without halting electrolysis and an electrolysis device for executing the method are provided such that: in operation of a two-compartment electrolytic bath, which has a membrane partitioning an anode compartment from a cathode compartment and in which a sulfide ion-containing white liquor for use in a pulp production process is fed into the anode compartment while direct current is supplied to the electrolytic bath to produce polysulfide in the anode compartment through electrolysis, and a sulfide ion-containing white liquor for use in a pulp production process that contains at least one of a scale cleaning agent and a scale inhibitor is fed to the anode compartment.

Continuous electrolysis method with electrolytic bath for polysulfide production and electrolysis device for implementing the same

A continuous cooking process making use of a digester, which includes therein, from a top toward a bottom of the digester, a top zone, an upper cooking zone, a lower cooking zone and a cooking/washing zone and also includes strainers provided at the bottom of the respective zones and wherein a cooking black liquor extracted from at least one of the strainers is discharged to outside a digestion system, a process for cooking a lignocellulose characterized by feeding, upstream of the top of the digester, a first cooking liquor containing an alkaline cooking liquor having a specified composition, feeding a second cooking liquor of an alkaline cooking liquor made mainly of sodium hydroxide to the upper cooking zone, and feeding a third cooking liquor of an alkaline cooking liquor similar to the second cooking liquor to the cooking/washing zone.
