Background & Aim: Medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.This experiment was conducted to investigate the effects of milk thistle (MT) and thyme seeds (TS) on the performance in broilers. Experimental: In this study, 160 one-day-old (Ross 308) male broiler chicks were divided randomly into four major groups with 4 replicates b...
This study was conducted to investigate the effects of garlic powder (GP) black seed (BS) and plant premix (GP and BS) in the diet on broiler growth performance and intestinal morphology. included 480 Hubbard broiler chicks(day-old). There were 4 treatment groups each consisting of 3 replicates. The four dietary treatments consisted of a control (basal diet), basal diet +0.5% GP, basal diet +0....
Feed ingredient costs have been a concern to the U.S. broiler industry. Some integrated operations have reduced apparent metabolizable energy (AMEn ) values to decrease live production costs. Our laboratory has previously determined that 36 to 47 d feed conversion and caloric conversion were optimized with broilers fed diets formulated at 3,200 kcal/ kg. Finishing broilers may respond to diets ...
A meta-analysis on the effects of management and animal-based factors on the performance and feed efficiency of growing pigs can provide information on single factor and interaction effects absent in individual studies. This study analysed the effects of such factors on average daily gain (ADG), feed intake (FI) and feed conversion ratio (FCR) of grower and finisher pigs. The multivariate model...
Cobb male broiler chicks (1,000) on new litter were used to evaluate effects of dietary electrolyte balance [DEB; Na+K-Cl, milliequivalents (mEq) per kilogram] under tropical summer conditions. Corn-soybean meal-based mash diets had salt (NaCl) alone or in combination with one or more supplements: sodium bicarbonate (NaHCO3), ammonium chloride (NH4Cl), or potassium bicarbonate (KHCO3). A comple...
this experiment was conducted to investigate the effects of different levels of creatine and protein in diets on performance and meat quality of broiler chickens. a total of 320 day old ross broiler chicks were used in a 2×4 factorial arrangement of dietary treatments comprised two levels of protein (ross recommendation and 10% higher than recommendation) and four levels of creatine (0, 0.1, 0....
The objective of this study was to investigate the effects of three levels of threonine (100, 95 and 90% of NRC requirements) with or without of multi strains probiotic (Primalac) on performance, carcass characteristics and blood metabolites of Japanese quails. A total of 180 one-day-old male Japanese quails were randomly allocated to six treatments with three replicates and 10 birds per each. ...
Commercial broiler males were used to evaluate body temperature response to heat stress and its relationship to gain, feed consumption, and feed conversion ratio. Individual gain, feed consumption, and feed conversion ratio were obtained from 28 to 49 d in a heat stress environment (32 C) and compared to a 21 C environment. Body temperatures were measured at 28, 35, and 42 d, then daily from 43...
In order to study the effects of L-carnitine on performance and some blood biochemical parameters of rainbow trout, the present experiment was conducted with 144 fish (130±5 g) for 8 weeks. In a completely randomized design, the experimental fish were divided into 9 groups with 3 treatments and 3 replicates and 16 fish in each group. Levels of L-carnitine supplements were 0 (control), 1 and 2 g...
the objective of the study was to compare the effects of antibiotic virginiamycin, probiotic protexin® and plantago major l. (plantain) on performance, serum metabolites, immune response, and the ileal microbial population of broilers. the experiment was carried out with a total of 200 day-old male ross 308 broiler chickens in a completely randomized design. chickens were allocated to five grou...
