this study was conducted to evaluate the effect of adding a commercial medicinal plant (mp) powder containing garlic (allium sativum) and thyme (thymus vulgaris) to diets that included olive pulp (op), on the performance and carcass characteristics of broiler chicks. a total of 240 day old male ross-308 broiler chicks were allocated into six iso-nitrogenous and iso-energetic dietary groups with...

this experiment was conducted to investigate the effect of phytase superdoses alone or in combination with citric acid (ca) in canola meal-based diets severely limited in available phosphorus (pa) on growth performance, plasma phosphorus (p), and tibia ash (ta) in broilers from 22 to 42 d of age. two hundreds and eighty 21-d-old male broilers were used in 28 pens of 10 birds per each. the exper...

A feeding trial was conducted to assess the effects of substituting melon (Citrullus lanatus) seed peel meal (MSPM) for yellow maize on haematological and serum biochemical indices Clarias gariepinus fingerlings 56 days. Fifteen fish each were stocked in eighteen plastic bowls (50-litre capacity) fed six iso-nitrogenous diets at graded MSPM levels 0%, 20%, 40%, 60%, 80% 100% twice daily 5% thei...

The present study was conducted to investigate the effects of dietary vegetable oils (VOs) replacing fish oil (FO) on fatty acid composition, lipid metabolism and inflammatory response in adipose tissue (AT) large yellow croaker (Larimichthys crocea). initial body weight a 10.07 ± 0.13 g. Three iso-nitrogenous iso-lipidic diets were formulated by FO with 0% (the control group), 100% soybean (SO...

This study aimed to evaluate the antioxidant potential of citric acid in plant protein based-diets offered juvenile tambaqui, Colossoma macropomum. Four isonitrogenous and isoenergetic diets containing different levels (0, 10, 20, 30 g.kg−1) were formulated. Fish (n = 160; 27.56±1.03 g) randomly distributed 310-L water tanks 16), with four replicates per treatment. After experimental period (80...

A total of 4,076 pigs (initially 86.5 ± 1.24 lb) were used across 2 experiments to evaluate the effect increasing ratios Val, Ile, and Trp Lys on pig growth performance carcass characteristics in corn-soybean meal-DDGS-based diets containing increased levels dietary Leu:Lys. In both experiments, 4 treatments as follows: 1) high soybean meal low feed grade amino acids (control); 2) acids, with V...

Background Nitrification inhibitors (NI) may be used to inhibit nitrous oxide (N2O) emissions from agricultural soils, but their efficacy could strongly affected by soil temperature and moisture. Aims This study investigated how different NI behave in a sandy under variable moisture levels, which currently remains unclear. Methods Efficacies of four [dicyandiamide (DCD), 3,4-dimethylpyrazole ph...

Several studies have assessed the effects of nitrogenous compounds on amphibian behavior. However, few have focused on the effects of their combination with other stressors or on the variation of the response to pollutants among populations. We analyzed the effect of nitrogenous compounds (NH(4)(+); NO(2)(-); NO(3)(-), both alone and in combination) on larval behavior (activity level and locati...

Ž . The use of a co-extruded soybean poultry by-product meal CEPM and flashed dried poultry Ž . by-product meal FD-PBM was evaluated as replacements for fish meal in a practical diet formulated to contain 32% crude protein and 8% lipid. Each meal was substituted for menhaden Ž fish meal on an iso-nitrogenous basis and offered to juvenile Litopenaeus Õannamei mean initial . Ž wt."S.D., 0.37"0.01...
