Sentences with phrase «feed conversion»
The phrase "feed conversion" refers to the efficiency with which animals convert the food they eat into the desired product, such as meat or eggs. It measures how much feed is needed to produce a certain amount of product. The lower the feed conversion ratio, the more efficient the conversion process is. Full definition
The similarity to livestock when using these efficiency measures is the opposite of the expected result based on weight - based feed conversion ratios.

The most widely used measure of feed efficiency is the weight - based feed conversion ratio, calculated as the ratio of feed intake (by weight) to weight gain.
The result is an optimal growth rate and good feed conversion.
And, as a result of lower feed conversion or egg production, it would also have an economic impact.
So decreasing the amount of methane they produce should improve feed conversion efficiency and so could be an improvement that pays for itself even without considering climate benefits.
Differences in gut microbiota composition in finishing Landrace pigs with low and high feed conversion ratios — Zhen Tan, Antonie van Leeuwenhoek
They don't need as much space as livestock, emit lower levels of greenhouse gases, and have a sky - high feed conversion rate: a single kilogram of feed yields 12 times more edible cricket protein than beef protein.
It's estimated that the cattle industry loses about $ 3 billion each year in lost weight gains, poor feed conversion and increased disease because of internal parasites.1 With the financial impact and animal welfare concerns on cattle operations, it is important for producers to understand parasite control, as well as the misconceptions about parasite control.
«We need a complete understanding of feed efficiency, though, because aquatic species differ from livestock in important ways that are not considered in feed conversion ratios.»
The study contributes new insights into what is known as feed conversion efficiency — that is, the efficiency of the process by which feed is turned into meat — across species, and uses a new analysis to assess this efficiency.
All Injector Dynamics Subaru WRX fitments (except our side feed to top feed conversion kits) are now shipping with the new adapters.
Rated as one of the top five breeds for producing large litters of piglets with some of the highest birth weights, the Landrace also boasts one of the most efficient feed conversion ratios.
A pooled statistical analysis of seven feedlot studies published between 2008 and 2010 showed cattle fed CATTLYST with AUREOMYCIN ® (chlortetracycline) ate 2.8 % more feed and gained 2.1 % faster with similar feed conversion when compared with cattle fed Rumensin and Tylan ®.
CO2 production and average daily gain (ADG) were quantified to provide an estimation of feed conversion efficiency.
They don't need as much space as livestock, emit lower levels of greenhouse gases, and have a sky - high feed conversion rate: a single kilogram of feed yields 12 times more edible cricket protein than beef protein.
It's estimated that internal parasites cost the cattle industry an estimated $ 3 billion each year in lost weight gains, poor feed conversion and increased disease.3
The pig has highest feed conversion efficiency i.e. they produce more live weight gain from a given weight of feed than any other class of meat producing animals except broilers.
In light of these findings, the researchers suggest that alternative retention measures should be used in addition to feed conversion ratios, as well as environmental footprint measures including resource use (e.g., land, water), greenhouse gas emissions and negative externalities including biodiversity loss and water pollution.
His research lead to the pedigreed Pekin duck, bred for better disease resistance, early maturity, feed conversion, weight and meat.
However, researchers say that feed conversion ratio estimates are flawed measures for comparing efficiency across species because they do not account for the nutritional content of the feed, the portion of the animal that is inedible or the nutritional quality of the final product.
To produce these efficiency estimates, the research team collected data on variables including feed composition, feed conversion ratios, edible portions and nutritional content of major farmed terrestrial and aquatic animal species.
