(1) technical field
The present invention relates to a kind of feed additive, especially a kind of control fattening pig feed intake, the plant source feed intake regulating and controlling agent and the application thereof that improve the fattening pig carcass quality.
(2) background technology
After the pig birth mainly is skeletal growth, and body weight 30～60kg mainly is the growth of muscle, and behind the body weight 60kg, body lipidosis is greater than the growth of lean meat.Arrived the fat deposition phase, pig is limited to the demand of protein, if again from feed a large amount of protein of picked-up will be converted into energy and fatty in subcutaneous deposition.So not only reduce feed conversion rate and caused waste, also reduced lean meat percentage simultaneously.For kind of livestock and poultry, in the nurturing period if too fast, the body lipidosis of growth too much (too fertile) can cause the decline of reproductive capacity.Therefore the pig growth phase before body weight 60kg is taked free choice feeding usually, allow pig fully grow, and take restricted scale of rationing the stage of fattening after body weight reaches 60kg usually, restriction hyperliposis deposition, can bring into play the growth potential of lean meat on the one hand to greatest extent, also can control the deposition velocity of fat on the other hand, thereby improve lean meat percentage.Phase raises and adopts the free choice feeding method entirely, and not only the efficiency of feed utilization of pig is low, and " big tripe " phenomenon occurs, so that dressing percentage decline, descends for port breeding pig ratio.Therefore,, reduce fat deposition, improve lean meat percentage, improve the build of market pig, improve ratio, increase the economic benefit of raising pigs, must take limit to raise measure, reduce its feed intake in the stage of fattening for port breeding pig in order to improve efficiency of feed utilization; For kind of livestock and poultry, the reproductive capacity (planting with being worth) in order to keep or improve kind of livestock and poultry needs to take limit to raise measure in the nurturing period usually
Two kinds of modes that limit raises that finite quantity is fed (restriction livestock and poultry feed intakes) and limit matter is fed (feed and give the daily ration that hangs down nutrient concentration).Restricted scale of rationing:, be the standard restricted scale of rationing with 75%～90% of free choice feeding forage volume by feeding standard preparation daily ration generally in the nurturing period of fattening the later stage or planting livestock and poultry; But required loaded down with trivial details of certain device that this feeding method needs and weighing every day and time-consuming job, and take a lot of work effort, troublesome poeration, being not easy to jumpbogroup raises, raising is searched for food as jumpbogroup, and the pig that precedence is high still can be satiated with food, and the low pig of the precedence of searching for food, can only be in starvation, obviously influence production performance, and seriously cause whose body weight difference, what be unfavorable for culturing advances with going out together.Limit matter is fed: low concentration energy feeds such as the suitable green grass or young crops of collocation, hay powder in the daily ration though this method is simple and easy to do, can obviously influences the build of pig and reduce dressing percentage.
In the market, can promote to search for food or to improve products such as the feed addictive of feed intake such as phagostimulant a lot, and be chemical products mostly, but not see the feed intake regulating and controlling agent report of the reduced feed intake that is applied to fattening pig.Along with the continuous enhancing of people to product safety consciousness, the product of plant origin is more favored than chemical products.Therefore, develop a kind of plant source feed intake regulating and controlling feed addictive, have good market prospects.Use this feed intake regulating and controlling agent and make the kind livestock and poultry of fattening pig or nurturing period under the free choice feeding condition, realize reducing the intake of feed, reduce, be convenient to jumpbogroup and raise because of required equipment of restricted scale of rationing and the work that takes by weighing of every day; Also can avoid simultaneously the fattening pig dressing percentage being descended because of limitting matter to feed.
