1. The present paper reports the effects on rumen fermentation and plasma metabolites and hormones of giving fixed rations of hay and high-cereal concentrates at different meal frequencies to lactating cows. In Expt 1 the total ration was given in two and twenty-four meals daily and in Expts 2-4 the concentrates were given in two and five or six meals and the hay in two meals daily. The diets c...

A study was conducted to evaluate the effect of feeding different levels of protein to black Baladi breed kids. Weanling Baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. Kids were divided randomly to one of the three treatments for 12 weeks. The three dietary treatments were: T1: control ration, formulated according to NRC to cover the protei...

) leaves meal in rations on nutrient digestibility, hematological status and malondialdehyde levels broiler chicken blood. The study was conducted experimentally with a completely randomized design, which consisted of 5 treatments replications. treatment the use combination cassava tuber indigofera (70%+30%; CCI) ration, namely: T0 (0% CCI ration), T1 (5% T2 (10% T3 (15% ration) T4 (20% ration)...

this research was conducted to study the nutrient balance condition of dairy cattle in semi industrial dairy farms of sought west of tehran province (eslamshahr) by the questionnaire techniques. the farms based on the herd were categorized in 6 group as follows: 1(1-30), 2(31-60).3(61-100), 4(100-130), 5(130-200) and 200 heads upward. the 30 farms have been selected randomly based on the random...

Two experiments were carried out to evaluate the effects of indigestible neutral detergent fiber (iNDF) of ration for estimation of rumen degradability of fiber in sheep. In experiment 1, to determine feed iNDF, four ruminal fistulated Zel ewes were used. Three grams of alfalfa hay, corn silage, barley grain, wheat bran, ration 1 (including alfalfa hay and concentrate), and ration 2 (including ...

This work aimed to study the effect of two different levels of ration energy supplemented with Alpinia officinarum. Rabbits were classified into six equal groups (G1-G6). The 1 and 4 groups received basal ration with 100 % and 90 % energy requirement and served as first and second control respectively. The 2 and the 3 groups received basal ration with 100 % energy requirement supplemented with ...

Two in vivo experiments were conducted to evaluate the effect of novel urease inhibitor hydroquinone (HQ) on ammonia release rate from urea hydrolysis, nitrogen balance, nutrient digestibility and efficiency of microbial protein synthesis. In Exp. 1, twelve crossbred cannulated lambs were randomly assigned within initial body weight block to one of four HQ treatments, which included 0 (control)...

The feeding of glucoascorbic acid, an analog of ascorbic acid, to mice and cotton rats caused the production of a condition exhibiting many of the changes characteristic of scurvy as seen in susceptible species. The condition was not prevented or cured by ascorbic acid, but was cured by removal of the glucoascorbic acid from the ration. The condition was produced in mice fed a highly purified r...
