This study was conducted to compare carcass characteristics and physico-chemical meat quality in two different genotype ducks raised under identical feeding and rearing conditions. A total of ninety 1-d-old Korean native ducks (KND, n = 45) and commercial meat-type ducks (Grimaud, n = 45) were fed same experimental diets during 56 d and 42 d, respectively to obtain similar slaughter weights. Th...

Biofloc technology is a modern-day high-density fish culture system employing heterotrophic conversion of nitrogenous waste into useful flocs for water quality control and improved welfare. However, optimization the stocking density target species during seed rearing key to successful farming operation. The study evaluated effect different on growth, feed utilization, digestive physiology econo...

A 5 x 5 Latin square design was used to determine the effects of restricted and ad libitum intake of diets containing wheat middlings on the site and extent of digestion compared to ad libitum intake of a corn-based diet and ad libitum intake of chopped alfalfa hay. Five ruminally and duodenally cannulated Angus steers (519 +/- 41.5 kg BW) were used to compare five dietary treatments. The five ...

this experiment was conducted to investigate the effects of using three commercial enzymes on performance and carcass quality of broiler chickens fed with wheat-barley-soy based diets. in a completely randomized design 405 of broiler (ross308) in nine treatments, three replicates (with 15 bird in each replicate) were used. the experimental diets included 1) diet based on corn–soybean meal (with...

Dietary supplementation with hydrolysates has been suggested to influence muscle protein synthesis and fish growth. This study assessed the impact of including 3% swine blood (BH) in a plant-based diet on cellularity expression molecular markers related fibre proliferation hypertrophic growth European seabass. Three BH fractions were obtained by two different processes, autohydrolysis (AH-H) en...

1. This study was carried out to investigate the effects of 1, 25-dihydroxycholecalciferol (1, 25 (OH)2 D3) and a hydroalcoholic extract of Withania somnifera (WS) root on performance, mineral retention, bone mineralisation, bone mechanical and bone histological characteristics of broiler chicks. 2. A 2 × 3 × 2 factorial experiment consisted of a positive control diet with adequate Ca and a neg...

This study was conducted to determine the bacterial composition and its effect on Artemia performance in various biomass culture conditions. Newly hatched franciscana were cultured 1.5L plastic bottles containing 1L of medium, with a density 200 nauplii/L salinity 30 ppt, lasted for three weeks. In first two days after stocking, fed Chaetoceros sp. Afterward, Artemia-formulated feed used as dai...

The present study was carried out to examine the chemopreventive effects of 5-fluorouracil (5-FU) and lactoferrin (LF) on goldfish intestinal carcinogenesis induced by 1,2-dimethylhydrazine (DMH). DMH was given to fish by intraperitoneal injection in a dosage of 15 mg/kg body weight once a week for 6 weeks. Eight weeks after the initial DMH injection, fish were randomly divided into 2 groups, c...

The mammalian gut microbiota influences various metabolic and physiological processes. Substantial metabolic changes occur during a healthy pregnancy that may be related to microbiota composition dynamics. However, the effect of diet on intestinal microbiota composition and diversity during pregnancy remains unclear. We examined the ileal contents of Huanjiang mini-pigs at two pregnancy stages ...
