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,...

Over the past years, poultry industry has been assigned to greater production performance but become highly sensitive environmental changes. The average world temperature recently risen and is predicted continue rising. In open-sided houses, species confront high outside temperatures, which cause heat stress (HS) problems. Cellular responses are vital in poultry, as they may lead identifying confirmed HS biomarkers. Heat shock proteins (HSP) preserved protein families that play a significant...

Weaned male New Zealand White (NZW) about 6 weeks old (n = 144, mean body weight 705 g) were randomly allotted four groups. Control group was fed a basal diet without GSE; experimental groups received with 100, 200 300 mg GSE/kg (Groups...

Poultry production is an important area of the agricultural economy. Nowadays, there interest in novel sources feed additives that will improve performance and poultry health. As easily available renewable biomass rich biologically active compounds, seaweeds can meet this demand. Different forms seaweeds–seaweed powder from naturally occurring biomass, cultivated or waste extracted post-extraction residues liquid extracts–may be used feeding. Inclusion unconventional material nutrition...

A total 96 (5 weeks old) distributed into four groups. first group received untreated pelleted diet (control). second was fed a containing ascorbic acid (AA; 1.0 g/kg diet), while the third fourth groups consumed diets supplemented with 200 gm OPE or (TPE, respectively. Our...

This study was conducted to verify whether vitamin (Vit) E or natural clay as feed additives has the potential modulate deleterious effects resulting from exposure cadmium (Cd) in growing Japanese quail. 648 quail chicks (1 week old) were used evaluate of dietary Cd (0, 40, 80 and 120 mg/kg diet) two levels Vit 250 (0 100 influences Cd, E, their different combinations on growth performance, carcass traits, some blood biochemical components residues muscles liver.

Floor type management is an important factor in turkey production hot climates exceeding 30°C. In this study, a total of 360 turkeys aged 4 wk were randomly distributed to investigate growth performance, carcass characteristics, certain health aspects (breast blisters score, footpad burns, hock discoloration, and plumage condition), airborne conditions. Birds the first group raised on littered floor (control; C), whereas birds other groups (T1, T2, T3, T4, T5) cement, wire net, rubber mat,...

This investigation studied the effects of different feed withdrawal times, water temperatures, and their interaction on growth performance, carcass traits, blood parameters, health aspects native turkeys (Egyptian local breed). We distributed turkey poults (n = 180; 4 wk old) into 3 groups according to time (ad libitum; from 800 1,400 h, FW8 14; 2,000 FW14 20). Each group was further divided 2 subgroups corresponding temperature (ordinary chilled water). Our results indicated that birds 20...

Influences of intermittent light regime as a tool to enhance egg production, quality, and blood parameters laying hens were investigated. A total 270 Rhode Island Red (during 20 36 wk age) used investigate the effects in completely randomized design. The birds divided into 3 equal groups (6 replicates 15 each) housed floor pens. first group was served non-treated control (C) exposed continuous constant for 16 h light/day throughout experimental period. Whereas, other lights min/h + 40 min...

Starting phase of laying chicken life is the building stone for rearing and production stages. Since, fecal microbial transplantation (FMT) regulates gut diversity affects productive performance bird. The aim this study to evaluate effect FMT from feed-efficient broiler could program microbiota growth recipient native slow growing egg-laying chicks. For this, a total 150 (one-day-old) Jing Hong chicks were randomly assigned into two groups, each group consisted 5 replicates (n = 15 bird/...

A 3 × 2 factorial arrangement was implemented to determine the performance of 450 Cobb broilers subjected different feeding regimes with and without lighting programs. The chicks were divided into groups according regime (ad libitum, restricted, or intermittent), each group reared under one two programs (100% continuous light 50% flashing light). results showed that ad libitum intermittent had superior body weight (BW) average daily gain (ADG) values lowest feed conversion ratio (FCR) at 6...

Abstract This work investigated the outcomes of dietary administration Echinacea purpurea (EP) powder to breeder ducks on productive and reproductive performance during summer season. Sudani (320 birds) 32‐weeks‐old (240 females 80 males) were randomly allocated into four collections (body weight; 1850 ± 15.2 g for 2960.0 40.5 males).

This experiment was conducted to observe the effects of varying swimming times (ST) Muscovy ducks, raised in an open-sided house, alleviating deleterious high temperature hotter day summer season on growth performance (body weight, average daily gain, feed consumption, and conversion ratio), carcass characteristics, body temperature, some health aspects. We hypothesized that during hottest periods would show different performances. To test this hypothesis a total 180 ducklings were randomly...
