linear programming is a helpful and applied method for diet formulation based on minimum cost, but the minimum cost does not always mean maximum profit. this study was carried out to introduce a new diet formulation method based upon maximum profit to be replaced for minimum cost method. a total of 400 one-day-old broiler chicks (ross 308) were employed in the study. all broilers were fed simil...

The aim of this study was to compare the effects of three antibiotic alternatives with a control (Antibiotic-free) and an antibiotic diet on performance and gut morphology of broilers reared on litter. 600 day-old ROSS-308 chicks were assigned to 48 pens in a CRD design with 6 × 2 factorial arrangements, in which 2 levels of chick density (5 and 7.5 chicks/m2) and 6 experimental diets (control,...

The objectives of this experiment was to evaluate the subsequent growth and organ weights, blood profiles and cecal microbiota of broiler chicks fed pre-starter diets containing fermented soybean meal products during early phase. A total of nine hundred 1-d-old chicks were randomly assigned into six groups with six replicates of 25 chicks each. The chicks were fed control pre-starter diet with ...

An experiment was conducted to investigate the comparative efficacy of two probiotics of different origins (yeast and bacterial based) on the growth performance, immune response, carcass characteristics and nutrient digestibility of broilers. One hundred and twenty day old chicks were purchased from local hatchery and were randomly divided into 4 groups and each group had 3 replicates of 10 chi...

This study was conducted to assess the effects of dietary monoglycerides and tributyrin on performance, blood metabolites, intestinal health function in nursery piglets. A total 96 crossbred entire male piglets (7.70 ± 0.49 kg) were allotted for 35 d a complete block design one four treatments: (1) negative control (NC): no feed additive, (2) positive (PC) containing 60 mg halquinol/kg diet, (3...

This research was conducted to compare the effects of two medicinal plants (peppermint and aloe vera) and antibiotic growth promoter on ileum microflora population and growth performance of broiler chickens. In this experiment, 375 one-day old male broiler chickens (Ross 308) were used on a completely randomized design with 5 dietary treatments which were replicated 5 times with 15 birds per re...

This study was carried out to determine the effect of L-arginine (L-Arg) levels in diet at the starter, grower and finisher phases on immune response, organ development, nitric oxide (NO) metabolism and colon motility in broilers. A total of 500 one-day-old Ross-308 broiler chickens of mixed sex were separated into one Arg-deficient group and four experimental groups. Each group was then divide...

A total of 180 crossbred, weanling pigs were assigned to five dietary treatment groups: 1) a basal corn-soybean meal diet formulated to current NRC recommendations, 2) basal + monosodium phosphate (2 x NRC P recommendations; P), 3) basal + alpha-tocopheryl acetate (220 IU/kg; E), 4) basal + sorbitol (1% of the diet; S) and 5) basal + PES. Dietary treatments were continued until market weight (1...
