Feed efficiency and surplus feed intake among Norwegian Red dairy cows

Journal of Dairy Science
: Feed in livestock production is a major cost driver and closely linked to GHG emissions from the sector. Hence, there is a great deal of interest to improve feed efficiency of livestock and promote economic and environmental sustainability of livestock

Short-Term Feeding Response in Chicks to Tea Saponin

The Journal of Poultry Science, 2001
Tea saponin is known to suppress chick growth rate by decreasing feed intake, although the mechanism by which tea saponin decreases feed intake remains obscure. Since tea saponin has bitter taste, palatability was suggested to be a major factor affecting

Performance and diarrhoea in piglets following weaning at seven weeks of age: Challenge with E. coli O 149 and effect of dietary factors [PDF]

, 2009
Four dietary factors (ad libitum versus feed restriction, control versus protein restriction at ad libitum feeding, control versus inclusion of lupine as a protein source at ad libitum feeding, and control versus extra vitamin E at ad libitum feeding ...

Effects of feed allowance and indispensable amino acid reduction on feed intake, growth performance and carcass characteristics of growing pigs

PLoS ONE, 2018
The hypothesis that pigs placed on diets with reduced indispensable amino acid (AA) content attempts to offset the reduction in the nutrient density with increased feed intake was tested.

Feed efficiency estimation from stochastic feed requirement frontier

Journal of Dairy Science
: Feed accounts for 40% to 70% of livestock production cost. Therefore, improving feed efficiency of production animals will promote farm profitability. To this end, precise estimation of animal level feed efficiency is important.

Effects of Incorporating Dry Matter Intake and Residual Feed Intake into a Selection Index for Dairy Cattle Using Deterministic Modeling

Animals, 2021
The inclusion of feed efficiency in the breeding goal for dairy cattle has been discussed for many years. The effects of incorporating feed efficiency into a selection index were assessed by indirect selection (dry matter intake) and direct selection ...

The effect of an 18-hour delay in solid feed provisioning on the feed intake and performance of piglets in the first weeks after weaning

, 2019
It is generally accepted that early post-weaning feed intake affects post-weaning health and performance. Especially piglets that have not consumed creep feed before weaning have to learn to recognize solid feed.

Wet Feeding Promotes Growth without Affecting Hypothalamic Peptide Gene Expression in Growing Broiler Chicks

The Journal of Poultry Science
From the perspective of animal welfare, freedom from hunger and thirst is an undeniable requirement for the poultry industry. Regulatory mechanisms underlying drinking behavior have not yet been identified in chickens; however, the regulation of ...
