Description
Technical field
The invention belongs to field of feed, particularly relate to a boar food.
Background technology
Feed refers to that all can by feed intake, digestion, absorption and utilization and to the nontoxic material of animal.Nutriment, referred to as nutrition, is commonly called as nutrient, refers to the chemical substance of animal in order to the product that sustains life, produces; Feed is the carrier of nutriment.
The concept of feed is development.The feed of sporadicly raising the epoch scattered refers to the material that animal can eat, comprise the byproduct after cereal and cereal processing, the byproduct after beans and squeezing thereof, the cake class after the processing of oil crops seed, green forage and the mankind eat after the remains of a meal etc., general without Processing farage, directly by animal edible; The feed in intensive Scale dependency epoch then refers to according to production standard, after being processed by feedstuff, directly or indirectly for the material feed of animal edible, can generally be divided into additive premix, concentrated feed, complete feed etc. by commercial run.
Additive premix is the homogeneous mixture that one or more feed addictives and carrier or diluent configure by a certain percentage.In China, custom becomes additive premix the product be made up of various active composition and raw material carrier/diluent.Additive is generally divided into trophism (amino acid, trace element, vitamin) and non-nutritive (antibiotic, expelling parasite health care, enzyme, probiotic, acidulant, flavor enhancement, antioxidant and anticorrisive agent etc.) two large classes.
Concentrated feed refers to based on protein feeds, adds the compound of mineral feed and various additive feed formulation.Can be chatted in feed as long as join, just form complete feed.

1.4.4 sow reproductive performance and body condition
When on-test divides into groups with during upper obstetric table, Body Condition Score is carried out to test sow.The newborn piglet number of detailed record every sow, number born alive, mummy number, stillborn foetus number, weak young number (that piglet litter weight at birth≤900g is weak son), and claim born weight.To the time interval of again oestrusing after the wean of record sow.
1.5 data statistics and analysis
Result average ± standard deviation represents, data SPSS13.0 software is analyzed, and the otherness between different disposal group adopts ANOVA variance analysis, thinks to have significant difference as P < 0.05.
2 test results and analysis
2.1 Different Alfalfa grass meal additions are on the impact of in-pig daily feedings
Different Alfalfa grass meal addition on the impact of in-pig daily feedings in table 3.As can be seen from Table 3, in in-pig daily ration, a small amount of alfalfa meal that adds affects little on the feed intake of sow, and when adding the alfalfa meal of 6wt%, the day of in-pig is 4.86 ± 0.41kg, is greater than 4.65 ± 0.53kg of control group.Meanwhile, also increase the average daily crude protein of in-pig and the intake of digestible energy, illustrate in in-pig daily ration that adding alfalfa meal is conducive to the raising of sow feed intake and the absorption of energy, and then beneficial effect is produced to the growing of piglet in sow body.Be it can also be seen that by table 3, add alfalfa meal in in-pig daily ration and to the time interval of again oestrusing, (P > 0.05) is not made significant difference to sow wean.
Table 3 Different Alfalfa grass meal addition is on the impact of in-pig daily feedings
2.2 Different Alfalfa grass meal additions are on the impact of in-pig constipation situation
On the impact of in-pig constipation situation as shown in Figure 1, Fig. 1 is the column diagram that Alfalfa addition affects in-pig constipation to Different Alfalfa grass meal addition.Constipation rate is greater than the number of days of more than 3 points divided by total number of days gained of feeding according to test sow stools scored, is an index of reaction prevention of sow constipation situation.As can be seen from Figure 1, add alfalfa meal in in-pig daily ration and can reduce sow in gravidic constipation rate, the constipation rate of 6% alternate sets is 7.68 ± 2.31%, reduces about 1.6% than 9.22 ± 2.12% of control group.Because ight soil situation differs greatly between sow individuality in process of the test, cause test data comparatively to be disperseed, the standard deviation of each processed group is larger.
2.3 Different Alfalfa grass meal additions are on the impact of reproduction performance of gestation sow
Different Alfalfa grass meal addition on the impact of in-pig production performance in table 4.As can be seen from Table 4, the Granulated alfalfa of 6% is added in in-pig daily ration, though litter size increases without conspicuousness with strong young number, be increased to 13.32 ± 3.20 and 12.84 ± 3.07 of test group from 12.81 ± 2.91 and 12.35 ± 2.84 of control group, numerically have the trend of increase.
It can also be seen that from table 4, along with the increase of alfalfa meal addition, the farrowing litter weight of sow can increase to some extent, is increased to 17.59 ± 3.77kg from 17.24 ± 3.67kg of control group, but difference is not significantly (P ﹥ 0.05).Meanwhile, because the litter size of Alfalfa alternate sets increases to some extent, so its piglet on average heavily can decline slightly to some extent.The alfalfa meal of 6wt% adds the birth weight (P ﹥ 0.05) significantly not affecting piglet.
Table 4 Different Alfalfa grass meal addition is on the impact of in-pig production performance
3 discuss
3.1 Alfalfas add the impact on in-pig feed intake
Due to many 6 ~ 7 times of the number ratio grower pigs of the cellulose-decomposing bacterium of Adult Pig, the reproductive performance of alfalfa meal to sow adding different proportion in sow diets does not have adverse influence.The key constraints that alfalfa meal is applied in swine rations is that crude fibre is higher, and digestible energy is low.But the crude fibre of higher level can be tolerated under the condition that pig is met at Diet energy density, pig also exist for can and the habit of food.So, alternate sets feed in this test, difference according to Alfalfa addition has carried out suitable adjustment to the ratio of raw material, and then ensureing that the energy of three processed group feeds is basically identical, in this test, the feed intake of 6wt% test group sow does not have to be subject to remarkable impact because of the interpolation of Alfalfa.
3.2 Alfalfas add the impact on in-pig constipation
Sow feeding alfalfa meal has many benefits, and it not only can improve the reproductive performance of sow, also can improve the content of sow colostrum and normal Ruzhong fat, is conducive to the growth of newborn piglet and survives, can also prevent abnormal behaviour.Constipation and MMA syndrome can also be prevented when Farrowing.In this test, add a certain amount of alfalfa meal in in-pig daily ration, to the constipation situation reducing sow, there is certain effect.
3.3 Alfalfas add the impact on reproduction performance of gestation sow
The sow gestation stage is a complicated physiology course, the blastocyst implantation become by development of fertilized ova is in uterus, in ovary, corpus luteum changes corpus luteum graviditatis into and continues synthesis and secretion progesterone, progesterone suppresses hypothalamus and hypophysis release GnRH and FSH, LH by feedback mechanism, set up gestation, the maintenance of gestation is mainly by the adjustment of progesterone.And litter size is mainly by the impact of ovulation rate, rate of fertilization and pregnancy period fetal survival rate.The research of some scholar shows the pregnancy duration sow, it can be made at the Body weight loss of pregnancy duration to sow feeding alfalfa meal, but childbirth piglet number and piglet birth weight can not be influenced, and the result of study of this and this test is basically identical.In this test, the birth weight of piglet is without obvious increase, may be lower relevant with the addition of alfalfa meal.Scholar's research is had to represent, add alfalfa meal and can improve piglet weigth at birth, this is more relevant with the volume of alfalfa meal, raise because carrying out limit during sow gestation, large volume diet can increase its satiety, thus adds the sleeping time of lying prone, and this just contributes to some bad behaviors reducing sow, reduce energy loss, increase the energy supply of concepts growth.
The production of sow comprises two aspects for pig industry: the service life of producing more piglet and prolongation sow.And keep good body condition to be the essential condition increasing sow service life.In this test, the body condition pregnancy duration of test group sow is without marked change, and what Alfalfa was described is added with the maintenance helping sow body condition, thus is beneficial to the gestation again of sow, can extend the utilization periods of sow.In addition, inter oestrual period and the control group no significant difference of sow is tested.
Alfalfa is excellent fiber feedstuff, by the impact of determination and analysis Different Alfalfa grass meal addition on in-pig constipation and reproductive performance, draw the following conclusions: in daily ration, add a certain amount of Granulated alfalfa, under the condition that fodder energy is met, the feed intake of in-pig is uninfluenced, constipation situation makes moderate progress, and piglet birth number and strong young number improve.
