Added Dietary Fat Improves Growth Performance and Feed Efficiency in Growing-finishing Pigs under Commercial Conditions
نویسندگان
چکیده
A total of 480 pigs was used in an experiment conducted in a commercial research facility to determine the influence of fat additions to the growing-finishing diet on pig performance and carcass composition. Adding fat to the diet from 80 to 265 lb increased ADG and F/G by 1 and 2%, respectively, for each 1% added fat. The growth response was greatest during the initial phase of the trial (80 to 130 lb) and declined as the trial progressed. The feed efficiency response was consistent throughout the trial. After adjusting for the greater carcass weight of pigs consuming the high fat diets, carcass parameters were not influenced by fat addition to the diet.

Effect of Supplemental Choline on Performance of Starting, Growing and Finishing Pigs: a Cooperative Regional Study
Severn hundred pigs were used in experiments at eight stations to evaluate the efficacy of supplemental dietary choline during the starting, growing and finishing production phases. Increasing levels of choline chloride were added to corn-soy-lysine basal diets formulated to contain 15% crude protein (.95% lysine), 13% crude protein, (.75% lysine) and 11% crude protein (.55% lysine) for the sta...
متن کاملCopper Enhances Performance of Pigs
Copper is a unique mineral, When it is added to pig diets at a high level (much higher than the nutritional requirement), copper stimulates growth and feed efficiency much like antibiotics do. This effect is particularly evident with young pigs. Table 1 shows results of UK studies over a 1 &year period in which high copper diets were fed to weanling pigs (from 17 to 40 lb). Copper increased gro...
متن کاملEffects of increasing crude glycerol and dried distillers grains with solubles on growth performance, carcass characteristics, and carcass fat quality of finishing pigs.
This study was conducted to determine the effects of dietary crude glycerol and dried distillers grains with solubles (DDGS) on growing-finishing pig performance, carcass characteristics, and carcass fat quality. We hypothesized that because dietary crude glycerol has been observed to increase carcass SFA, it might ameliorate the negative effects of DDGS on fat quality. The 97-d study was condu...

Three experiments were conducted to determine the optimal level of dried distiller grains with solubles (DDGS) from a common ethanol manufacturing facility and to determine the potential interactions between dietary DDGS and added fat on performance and carcass characteristics of growing and finishing pigs. All experiments were conducted at the same commercial facility and used DDGS from the sa...

This study was conducted to investigate the influence of dietary rapeseed meal (RSM) on growth performance, blood profiles, nutrient digestibility and economic benefit of growing-finishing pigs. A total of 120 growing pigs ([Yorkshire×Landrace] ×Duroc) with an initial body weight (BW) 29.94±0.06 kg were used in this experiment. Pigs were randomly allotted into 1 of 5 treatments in a randomized ...
