Effects of Supplemented Resveratrol on In Vitro Ruminal Fermentation and Growth Performance of Hanwoo Calves.

We investigated the effects of resveratrol supplementation on in vitro ruminal fermentation and growth performance of Hanwoo calves. Treatment with three resveratrol concentrations (0%, 0.1%, 0.

Effects of Feed Composition in Different Growth Stages on Rumen Fermentation and Microbial Diversity of Hanwoo Steers.

Ruminants are a major source of greenhouse gas emissions, and information on ruminant fermentation and microorganisms is essential to understand ruminant digestion, which is associated with environmental pollution. The present study investigated rumen fermentation and microbial diversity according to the three different growth stages of four Hanwoo steers: growing (12 months, G), early fattening (18 months, EF), and late fattening (25 months, LF). No significant differences were observed in rumen pH and ammonia nitrogen among growth stages.

Effects of Dietary Supplementation of Black Soldier Fly () Larvae Oil on Broiler Health.

Insects are a potential source of proteins and fats which can be incorporated into diets of broiler chickens. Accordingly, black soldier fly larvae oil (BSFLO) needs to be tested as an appropriate fat source to produce healthy chickens for consumers. Therefore, the objective of the present study was to evaluate the effects of the replacement of soybean oil (SBO) with BSFLO in broiler diets on intestinal health and blood profiles.

Effects of Dietary Inclusion Level of Microwave-Dried and Press-Defatted Black Soldier Fly () Larvae Meal on Carcass Traits and Meat Quality in Broilers.

Limited information is available regarding the use of microwave-dried larvae meal (HILM) as a dietary protein source for broiler diets. Therefore, we investigated the effects of microwave-dried HILM on carcass traits, meat quality, fatty acid (FA) profiles of abdominal fat and meat, and heavy metal residues of the meat in broilers. A total of 126 male broilers were randomly assigned to three dietary treatment groups (6 replicates and 7 birds/pen): a control diet and two experimental diets in which soybean meal was replaced with 25 or 50% HILM.

Evaluation of black soldier fly larvae oil as a dietary fat source in broiler chicken diets.

The present study was conducted to evaluate the effects of black soldier fly larvae oil (BSFLO) from the black soldier fly larvae (BSFL) as a partial or total replacement of soybean oil (SBO) on growth performance, fatty acid (FA) profile, and meat quality of broiler chickens from 1 to 5 wk of age. A total of 210 male broiler chickens (Ross 308) at one-day of age were randomly allotted to 3 dietary treatments (10 replicates and 7 birds/group): a basal control diet (CON), the basal diet in which the SBO was replaced by 50% (50 BSFLO) or 100% (100 BSFLO) of BSFLO. The growth performance, physical measurements and chemical traits of leg meat, and sensory analysis of breast meat were not influenced by diets.

Comparison of sample preparation procedures of inductively coupled plasma to measure elements in dog's hair.

The pre-treatment condition affects on the element analysis of inductively coupled plasma (ICP). In this study the pre-treatment condition of ICP has been studied to quantify elements in dog's hair. The hair samples were collected from twelve female Beagles by clipping them into 1 or 2 cm at the back neck.

A simple method to evaluate body condition score to maintain the optimal body weight in dogs.

Overweight and obesity induce serious health problems that exert negative effects on dog's welfare. Body condition score (BCS) is a common method to evaluate the body fat mass in animals. By palpating and observing fats under the skin it is possible to predict animal's body fat accumulation condition.

Identification of the acclimation genes in transcriptomic responses to heat stress of White Pekin duck.

White Pekin duck is an important meat resource in the livestock industries. However, the temperature increase due to global warming has become a serious environmental factor in duck production, because of hyperthermia. Therefore, identifying the gene regulations and understanding the molecular mechanism for adaptation to the warmer environment will provide insightful information on the acclimation system of ducks.

Effects of anti-heat diet and inverse lighting on growth performance, immune organ, microorganism and short chain fatty acids of broiler chickens under heat stress.

The present study investigated the effects of night restricted feeding of extreme heat diet (EHD) containing heat stress resistance nutrients, with inverse lighting program, on their growth performance in broiler chickens exposed to extreme heat stress (33 ± 2°C). EHD 1 contained soy oil, molasses, methionine and lysine. EHD 2 contained all nutrients of EHD 1 and vitamin C additionally.
