Interaction of wheat cultivar and enzyme on broiler growth, nutrient utilization, and gut microflora.

This study examined the impacts of four wheat cultivars and enzyme supplementation on growth performance, nutrient digestibility, and ileal microbiota composition in broiler chickens. Six hundred forty-eight male broilers (1-day-old, Ross 308) were studied in a completely randomized design factorial 4 × 2 along with control (9 treatments) with 6 replications (12 birds per pen). The Diets consisted of the four varieties of wheat (Sardari, Azar2, Sirvan, and Pishgam) with and without enzyme supplementation, alongside a corn-based control diet.

Interactions of dietary wheat cultivars and NSP-degrading enzyme on productive performance and egg quality traits.

Context: The nutritional value of enzyme-supplemented wheat-contained diets can be influenced by interactions between wheat cultivar and exogenous enzyme, which in turn cause various effects on the performance of poultry.

Aims: The effects of diets including various wheat cultivars with or without enzyme on productive performance and egg quality characteristics were evaluated.

Methods: A total of 270 58-week-old Lohmann LSL-Lite were allocated to 9 experimental dietary groups with 5 replicate cages and 6 birds per each cage.

Effect of dietary roasted and autoclaved full-fat soybean on the performance of laying hens and egg quality traits.

Context: Full fat soybean (FFSB) can be used in poultry diets as a source of fat and protein, without extra cost for oil extraction; however, raw FFSB contains several anti-nutritional factors.

Aims: Investigating the effects of replacing dietary soybean meal (SBM) with processed (roasted or autoclaved) FFSB on the performance of laying hens and egg quality traits.

Methods: A total of 324 Bovans White strain laying hens were randomly selected and distributed in 54 replicate cages.

The and genes polymorphisms associated with early embryo development of Sanjabi sheep.

This study aimed to investigate the association between polymorphisms of and genes and early embryo development of Sanjabi sheep. Blood and ovarian samples were collected from a local slaughterhouse. The cumulus-oocyte complexes with a diameter greater than 3 mm were aspirated from follicles, and maturation (IVM) and culture (IVC) rates of them were recorded.

The relationship between mitochondrial gene polymorphisms and embryo production in Sanjabi sheep.

The aim of this study was to investigate mitochondrial ND5 gene polymorphisms and their relationship with in vitro maturation (IVM) and in vitro culture (IVC) of Sanjabi sheep. Blood and ovarian samples of adult ewes were obtained from a local slaughterhouse. For each ovarian sample, cumulus-oocyte complexes larger than 3 mm in diameter were aspirated from follicles, and their IVM and IVC rates were recorded.
