the effects of probiotic (protexin) and formic acid were studied on humoral and cellular immunity in 200 cobb broiler chicks in a completely randomized design of with 4 treatments and 5 replications (10 observations per replicate). control group (c) did not receive any other than the base treatment. the chicks in the second (p), third (f) and forth (p+f) groups were fed with feed, which contain...

Broiler birds (Vencob chicken of 3 days old) when given feed mixed with powdered rhizome of Curcuma longa (CL; @ 1 g/kg) for 42 days of age, showed significant decrease in serum uric acid and albumin as compared to control, whereas significant increase was recorded in the level of serum total protein and globulin. Level of serum glucose, alkaline phosphatase, aspartate amino transferase and cal...

The aim of this study was to evaluate the effect of castration and slaughter age on performance and meat quality of Holstein bulls fed a high-concentrate diet. A total of 132 animals (116 ± 3.7 kg of BW and 97 ± 2.4 d of age) were randomly allocated in 6 pens using a 3 × 3 factorial arrangement of treatments. Three castration ages [bulls, animals castrated at 3 mo (CAS3), and animals castrated ...

effects of partial docking on feedlot performance and body fat characteristics were studied in a fat-tailed sheep breed. thirty-eight male lambs with an average weight of 4.44 ± 0.48 were randomly divided into two groups. the lambs in one group were partially docked at 3-4 h after birth, using rubber rings, and the lambs in another group remained intact (control). after weaning, 20 male lambs f...

Responses to increased dietary Lys concentrations were evaluated on 1,584 Ross 308 male broilers between 21 and 42 d of age housed according to 2 bird densities. The experimental design was composed of 8 factorial treatments: 2 bird densities (22 or 44 broilers/ 1.7 m(2) pen) x 4 true digestible (TD) Lys levels (0.83, 0.93, 1.03, and 1.13%). There were 6 repetitions per treatment. Birds were we...

This trial was undertaken with the objective to evaluate the efficacy of amprolium, toltrazuril and their combination in rabbits naturally infected with Eimeria species (32 × 103 ± 4.63 oocysts per gram (OPG) of faeces). Thirty-six rabbits (11 weeks old with average body weight (BW) 2000 ± 75 g), were randomly allocated into six groups (six kits each), namely, negative untreated and was retaine...
