Enhancing the Production Performance and Nutrient Utilization of Laying Hens by Augmenting Energy, Phosphorous and Calcium Deficient Diets with Fungal Phytase () Supplementation.

A ten-week trial was conducted to evaluate the enhancement of production performance and nutrient utilization of laying hens through augmenting energy, phosphorous, and calcium deficient diets with fungal phytase () supplementation. 720 Hy-line Brown hens aged 28 weeks were randomly divided into 5 groups; each group had 8 replicates of 18 hens. Five experimental diets were prepared and fed to corresponding groups.

Tolerance evaluation of Moringa oleifera extract to Hailan brown laying hens.

The aim of this experiment was to study the effects of dietary addition of high-dose Moringa extract (10 g/kg Moringa extract) on laying performance, haematological parameters, organ index and organ histopathology of Hailan brown laying hens in order to determine the safety limit of Moringa extract in laying hens diet. 270 Hailan brown commercial laying hens with similar body weight were randomly divided into three treatments, 6 replicates per treatment and 15 chickens per replicate. Corn-soybean meal-based diet was used in the experiment, and 0, 0.

Effects of dietary ramie level on growth performance, serum biochemical indices, and meat quality of Boer goats.

This study was conducted to evaluate the use of ramie as forage on growth performance, serum biochemical indices, and meat quality of Boer goats. For this, 60 Boer lambs were divided into four groups fed the TMR with 0%, 10%, 20%, and 40% (control, and groups I, II, III, respectively) ramie. The experiment lasted for 90 days with a pretest for 15 days.

Effects of various weaning times on growth performance, rumen fermentation and microbial population of yellow cattle calves.

Objective: This study was conducted to investigate the effects of weaning times on the growth performance, rumen fermentation and microbial communities of yellow cattle calves.

Methods: Eighteen calves were assigned to a conventional management group that was normally weaned (NW, n = 3) or to early weaned (EW) group where calves were weaned when the feed intake of solid feed (starter) reached 500 g (EW, n = 5), 750 g (EW, n = 5), or 1,000 g (EW, n = 5).

Results: Compared with NW, the EW treatments increased average daily gain (p<0.

Application of a novel alkali-tolerant thermostable DyP-type peroxidase from Saccharomonospora viridis DSM 43017 in biobleaching of eucalyptus kraft pulp.

Saccharomonospora viridis is a thermophilic actinomycete that may have biotechnological applications because of its dye decolorizing activity, though the enzymatic oxidative system responsible for this activity remains elusive. Bioinformatic analysis revealed a DyP-type peroxidase gene in the genome of S. viridis DSM 43017 with sequence similarity to peroxidase from dye-decolorizing microbes.
