a chick bioassay with chemically defined amino acid (aa) diets was conducted to compare four different aa profiles: the nrc (1994), feed stuff, rhone poulenc animal nutrition (rpan) and illinois ideal chick protein (iicp) aa profiles. this battery study involved male and female chicks during grower (21 to 42 days of age) period. indispensable aas were rationed to lysine according to requirement...

Twenty Ardi lactating goats were used to investigate the effect of substituting 10%, 15%, and 20% of concentrate feed with date pits on milk production, composition, and blood parameters. Four isocaloric and isonitrogenous dietary treatments were used. Four levels (0% [control], 10%, 15%, and 20%) of date pits were used to replace concentrate feed. The forages to concentrate ratio used was 60 t...

an experiment was conducted to investigate the effects of using different levels of ginger rhizome powder (grp) and turmeric rhizome powder (trp) on production performance and some blood metabolites in laying hens. ninety 103-week old laying hens were divided into 5 treatments in a completely randomized design with 3 replicates and 6 birds in each cage. the birds were fed a corn-soybean meal ba...

The monoclonal antibodies anti-2H4 and anti-4B4 identify the suppressor-inducer (CD4+2H4+) and helper-inducer (CD4+4B4+) subpopulations of CD4 (T4+) lymphocytes, respectively. The cell surface phenotype of peripheral blood lymphocytes and synovial fluid lymphocytes in patients with rheumatoid arthritis and other inflammatory joint diseases was analyzed by use of these and other well-characteriz...

this experiment was conducted to investigate the effect of synbiotic and two levels of dried garlic powder on performance during 1-49 and ileum morphology and microbial population at 49d of age in broiler chicks. the experiment was conducted in a completely randomized design with 5 treatments, 4 replicates of 10 chicks per replicate. the dietary treatments consisted of 1) control diet without a...

in order to study the effect of different levels of β-mannanase enzyme on the performance, blood parameters and carcass characteristics of broiler chicks (arbor acres), an experiment was conducted with 240 checks (44.6 grams average weight) under a completely randomized design with 4 treatments and 5 replications and 12 checks per each replicate. β-mannanase enzyme with the levels of zero (t1 c...

The performance characteristics of assays is reported for thyroxine (T4), triiodothyronine (T3), and T3-uptake (T3U) using the GAMMAFLOTM Automated Assay System. A comparison of calculated free thyroxine index (FTI) values is also presented. This automated radioimmunoassay (RIA) system utilizes a combination of continuous-flow methodology and chromatographic separation techniques. The T4 assay ...

This experiment evaluates the effect of decreasing dietary CP, in addition to the effects of dietary supplements of L-Thr to low CP diets, in Large White Nicholas toms from 0 to 18 wk of age. Toms were fed dietary treatments consisting of four levels of dietary CP as a percentage of NRC (1994) recommendations (100, 92, 84, and 76% of NRC recommendations). Additional treatments consisted of supp...
