The aims of this study were to evaluate the correlation between in vitro crude protein digestibility coefficients insect meals from Tenebrio molitor (TI) and Hermetia illucens (HI) their chemical composition traits as well develop regression equations able estimate (CPd) proximate analysis meals. Twelve samples (6 TM larvae, 1-6 6 HI 1-6) obtained different producers analysed for by a two-step enzymatic method (digestion with pepsin trypsin-enriched pancreatin). For both meal samples, CPd...
The aim of the research was to study effects an insect meal from Hermetia illucens larvae (HILM) as complete replacement soybean (SBM) on productive performance and blood profiles laying hens, 24 45 wk age. A total 108 24-week-old Lohmann Brown Classic hens equally divided into 2 groups (54 hens/group, 9 replicates 6 hens/group). From age, were fed different isoproteic isoenergetic diets: control group a corn-soybean based diet, while in HILM completely replaced by meal. Feed intake, number...
The aim of the study was to evaluate feasibility replacing soybean meal (SBM) with Tenebrio molitor larvae (TML) in broiler diets. A total 80 30-d-old male Shaver brown broilers were divided into two groups fed on isoproteic and isoenergetic diets differing for protein source (SBM vs. TML). Up 62 d age, body weight feed intake recorded weekly gain, conversion ratio (FCR), efficiency (PER) European factor (EEF) calculated. At d, blood samples collected from 16 birds/group evaluation profiles....
Heat stress had a negative effect on laying hens’ performance, thus this research was to study the influences of betaine (Bet, 1000 mg/kg betaine), vitamin C (VC, 200 ascorbic acid), and E (VE, 150 α-Tocopherol acetate) their possible combinations egg production, digestibility nutrients, plasma hormones reproductive organs dual-purpose hens exposed chronic heat stress. Two hundred eighty eight thirty-six cocks from 32 48 weeks age were divided into nine treatment groups four replicates, each...
Abstract Heat stress is one of the major challenges which poultry industry faces during summer in tropical and subtropical regions. This study was conducted to evaluate impact Vitamin (Vit) E, C and/or probiotics on improving tolerance broiler chickens chronic heat (CHS). A total 294, 1-day-old Cobb-500 chicks were allocated into seven treatment groups; Thermoneutral group raised under a thermoneutral condition 25–42 d age. The other six groups for three successive days per week at 36±2ºC...
Eggs are an important source of food due to its favorable effects on human health derived from the protein, fats, minerals, vitamins and bioactive components. We studied eggs in retail market fatty acids, lipid profiles antioxidant status eggs. four sources named A, B, C, D were collected determine acid, total lipid, cholesterol profiles; hypocholesterolemic, atherogenic thrombotic indices; (e.g., malondialdehyde); capacity whole edible parts (albumen + yolk) egg yolk. Samples times pooled...
We assessed the concentrations of Fe, Cu, Zn, Mn, Se, Co, Cr, Pb, Cd, and Ni in chicken meat products, feed, litter, as well laying hens’ eggs, feed litter to monitor quality products on market their safety for human consumption judged by recommended daily allowance (RDA) tolerable upper levels. Samples were chosen most popular poultry Saudi Arabia. A total 45 broiler samples frozen or fresh meat, liver, burger, frankfurter from same brand. Additionally, 60 table eggs four commercial brands...
Broiler meat is an essential source of food due to its favourable effects on human health derived from protein, fats, minerals, vitamins and bioactive components. A total 90 carcasses were collected the retail market in Jeddah city, Saudi Arabia during April, May June 2014 determine type (frozen vs. fresh) sources within fresh types (A, B, C) frozen (D, E F) their fatty acid profiles, cholesterol, hypocholesterolemic, atherogenic thrombogenic indices, antioxidants' status. The had a...
Effects of dietary supplemental zinc and/ or selenium enriched spirulina (Zn-Sp, Se-Sp and Zn-Se-Sp, respectively) as antioxidants on growth performance, nutrient digestibility, plasma biochemicals antioxidant status growing rabbits under summer conditions were evaluated. A total 160 New Zealand White male at six-weeks-old randomly assigned to four groups. The first group received untreated diet (control). other groups supplemented with 100 mg Zn-Sp/kg diet, 0.5 Se-Sp/kg Zn-Sp+ Se-Sp,...
Summary Four hundred and twenty, 21‐day‐old slow‐growing chicks were divided randomly into seven treatments, each containing five replicates. Each replicate was kept in a 1 × 1‐m floor pen. One treatment under thermo‐neutral conditions semi‐open house fed corn–soybean meal diet (positive control). The other six groups chronic heat stress (CHS) at 38 °C 60% RH for 4 h from 12:00 to 16:00 pm three successive days per week. Chicks CHS treatments corn‐soybean without (negative control) or with...
One hundred and twenty (100♀ + 20♂) 30-weeks-old dual-purpose breeding hens of Gimmizah strain were housed in individual cages a semi-open house. Birds distributed randomly into five treatments 20♀ 4♂. The 1st treatment was fed control (unsupplemented) diet (17.5% CP 11.4 MJ per kg diet) containing 0.10 mg Se/kg (low level). 2nd, 3rd, 4th 5th the supplemented with 0.15 0.30 from inorganic (sodium selenite) organic (selenomethionine, as Se-yeast Selplex® Alltech, Nicholasville, USA)...
The impact of dietary regimens on productive traits, meat quality, physiological adoption, immunological response and digestibility nutrients was studied using Ross-308 Cobb-500 strains. Chickens were reared under normal brooding conditions during most the experimental period, but exposed to heat stress [(HS); 32 °C 55% RH] 20–22 28–30 d age. During 1–18 age, broilers fed a standard-protein diet [(SPD); 22% crude protein (CP) with 12.97 MJ/kg], high-protein [(HPD); 24% CP or...
Summary A total of 140, 28-day-old male Ross-308 broiler chickens were used in a straight-run experimental design. The broilers distributed among 4 treatment groups. One group was raised under thermoneutral condition (28 ± 4°C and 40–60% RH) fed on basal diet containing 19% CP 13.18 MJ ME/kg during days 28–49 (thermoneutral group). other three groups (2, 3 4) for successive per week 36 3°C RH 6 h day from 10 a.m. to p.m. Group 2 kept chronic heat stress the considered negative control. feed...
