What are the factors affecting feed conversion ratio?
Anything that affects live weight, feed intake or feed wastage will influence FCR. The key to preventing FCR problems is ensuring that throughout the brooding and grow-out period, good management practices are in place.
What effects FCR in pigs?
Although the major factors affecting pig performance are known [2–4], such as genetics, nutrition and feeding, housing conditions and health, studies relating these variables with each other, especially genetics to nutrition and feeding [5, 6] and health [7] are scarce.
How do pigs increase feed conversion?
Another way we can improve feed efficiency is by increasing the nutrient density of the diets. This can either be achieved by feeding additional energy (tallow or vegetable oils) or adding enzymes such as phytase, xylanases and β-glucanases to break down indigestible fractions in the diet.
What is a pigs feed conversion ratio?
Feed conversion is a measurement of the amount of feed needed for an animal to gain one pound of bodyweight. A low feed conversion ratio indicates your pigs are efficiently turning feed into bodyweight. ... You would calculate the ratio as “665 pounds of feed divided by 240 pounds of gain for a score of 2.77.”
What do you think are the factors affecting the digestibility of feeds and the feed conversion efficiency?
Protein level: When several feeds are fed in a ration, one feed may influence the digestibility of the other. ... Carbohydrates: The nature and level of dietary carbohydrates affect the digestibility of all nutrients present in the diet. High crude fibre content of mixed diets decreases their digestibility.
What are the factors to consider in feeding pigs?
Feeds should meet the animal's needs for maintenance, growth and reproduction. Good pig feed contains sufficient energy, protein, minerals and vitamins. Rice bran, broken rice, maize, soya-beans, cassava, vegetables and distillers' residues are often used in pig feed.
What animal has the best feed conversion ratio?
The highest feed conversion rate was reported for cattle with an average ratio of eight. That means, cattle needs about eight kilograms of feed to increase its bodyweight by one kilogram.
How is feed conversion ratio calculated?
The Feed conversion ratio (FCR) is: FCR = Total feed consumed / Total weight of product produced , where: Total weight of product produced = final weight of the product – starting weight of the product.
How can I increase my feeding efficiency?
There are two ways to improve feed efficiency. One is to increase milk yield with the same dry matter intake, and the other is to decrease dry matter intake and maintain the same milk yield. Many diet modifications that increase milk yield will also increase feed efficiency.
What is feed conversion ratio in broilers?
A red label chicken of slow-growing strain reared outdoors and slaughtered at 81 days will have an average FCR value ranging between 2.8 to 3.2. A standard broiler chicken reared in an enclosed house will have an FCR between 1.5 to 1.9.
How do you calculate feed conservation ratio?
In the context of aquaculture, the F.C.R. is calculated as follows: F.C.R. = Feed given / Animal weight gain. In other words, the F.C.R. is the mathematical relationship between the input of the feed that has been fed and the weight gain of a population.
How do you calculate feed intake for pigs?
The U.S. National Research Council, in their publication, Nutrient Requirements of Swine, provides an equation that estimates the daily energy intake in the pig based on body size: DE INTAKE = 13,162 x (1 - e-0.0176BW) where BW is body weight of the pig and "e" is a constant = 2.7183.
What is restricted feeding?
Restricted feeding refers to restricting the amount of food while still ensuring nutritional adequacy [67]. This implies that only the amount of energy has been restricted.
