Feeding and management:

1. the feeding and management of stud ram

Stud ram wants individual pen to raise, and ram wants independent cohort to herd, move and supplementary feeding, and except breeding, discord ewe is put together.Breed vigorous season, for ensureing to be highly sexed, suitable supplementary feeding be carried out, keeping better-than-average fat; Stud ram also will regularly be quarantined, immunization campaign and control ecto-and endoparasites, and notes observing the daily state of mind.(1) regularly quarantine: Yang Chang wants regularly to quarantine monitoring to tuberculosis, brucellosis, is at least 1 year 1 time.The positive sheep of Timeliness coverage also carries out Prevention technology, and this is the needs ensureing flock of sheep health and livestock product safety.

(2) immunization campaign: the immunity inoculation work mainly should carrying out sheep pox, sheep clostridium welchii disease, sheep aftosa etc., and carry out in time benefit prevent.

. the feeding and management of ewe

(1) goat belongs to seasonal oestrus, and about the two weeks arrived sexual season, carry out the rejuvenation of fattening of ewe, in order to breed, gestation stocks nutrition.Dietary Supplement Dietary standard, to maintain based on normal metabolism, to ewe more thin and weak after wean, also will suitably have additional nutrients, to reach multiple fat.

(2) gravidic feeding and management is at first 3 months of gestation because development of fetus is comparatively slow, and nutritional need is substantially identical with the nonpregnant phase.At latter 2 months of gestation, because development of fetus is very fast, 80% of fetal weight grew in these two months, therefore, within these two months, should have the nutrition of abundance, full price, metaboilic level should improve 15% one 20%, calcium, phosphorus content should increase by 40% one 50%, and will have enough vitamin As and vitamin D.Select the comparatively smooth place of physical features to herd, slowly drive.

(3) feeding and management 2 months postpartum ~ 3 month of lactation are lactation.2 months postpartum, breast milk was the important nutrient of lamb, was especially born in latter 15 days ~ 20 days, was almost unique nutriment, should ensures ewe full value feeding.General daily gain 200 grams-250 grams, often increased weight 100 grams and needed breast milk about 500 grams, and produce 500 grams of breasts, need 0.3 kilogram of air-dry feeds, i.e. 33 grams of protein, 1.8 grams of calcium and 1.2 grams of phosphorus lactation.To later lactation, due to lamb search for food feed increase, can reduce gradually until stop the feed supplement to ewe.The consumption of attentional manipulation fine fodder is wanted in the management of wet sheep, and in 1 day ~ 3 days postpartum, the fine fodder that ewe can not overfeed, can not feed the tinkling of pieces of jade, frozen water.Before lamb wean, succulent food and fine fodder hello amount should be reduced gradually, prevent mammary gland disease.Ewe house often will be swept, sterilize, and the dirt such as afterbirth and hair ball will be removed in time, the morbidity in case lamb eats.

Ewe each stage conceived is different to the demand of nutrition, rationally must feed for different phase.It is below the nutritional need of different phase.

(1) ewe pregnancy about 1 month is the critical period of embryo growth and development, and ewe also suitably should be mended according to the nutrition condition of ewe and feed fine fodder after herding and mend and feeding and search for food and reach full abdomen.

(2) ewe pregnancy after two months, and the benefit increasing fine fodder gradually feeds amount.Fine fodder soya bean 40%, corn 30%, barley 20%, wheat 10%, emerge in worm water 6 hours ~ 8 hours, wear into slurry, add feed total amount 10% ~ 15% soya-bean cake, 5% ~ 8% bran, 1% salt such as being equivalent to soya bean, mend every day and feed 2 times ~ 3 times, every sheep feeds 50 grams ~ 100 grams at every turn, and young ewe suitably increases the amount of feeding.

(3) ewe is after conceived 3 months, and suitable control is fed to the total amount of forage grass, and benefit feeds forage grass and fine fodder should hello duty add less, in case the disposable amount of feeding too much oppresses fetus.

(4) after ewe is four months pregnant, the scale of feeding of fine fodder is increased to 2 times of conceived early stage, and the green succulent feeds such as many hello tender herbage, carrots, prohibit and feed potato, vinasse and cottonseed cake, colza cake without detoxification process, prohibit feed go rotten rotten, cross cold or overheated, acid overweight feed, in order to avoid cause ewe to miscarry, have difficult labour and occur postpartum disease.

(5) antenatal about 1 month, suitably control coarse fodder scale of feeding, feed feed that is soft to quality, dark green succulence as far as possible, increase wheat bran in fine fodder and feed amount, convenient with logical intestines.Give a birth first 10 days, according to ewe digestion, appetite situation, reduce feed and feed amount.Antenatal 2 days ~ 3 days, ewe breast swelled and with oedema under abdomen, amount fed by the feed that should reduce 1/2 ~ 1/3 from daily ration, in case childbirth initial stage milk amount is too much or milk overrich causes mastitis, lamb diarrhea etc.

. the nursing of lamb and cultivation

The cultivation of lamb, not only affects it and grows, and will affect its lifelong growth and productivity.Intensive care, to raising lamb survival rate, improves flock of sheep quality and has important function, therefore, must pay much attention to the management of lamb.

The colostrum phase: new-bom lamb should be allowed to eat as early as possible, eat colostrum more, eat more early, eat more, increase weight faster, physique is stronger, and morbidity is few, and survival rate is high.

Normal breast phase (6 days ~ 60 days): this one-phase, milk is the Major Foods of lamb, is aided with a small amount of forage.From 45 ages in days of coming into being, it it is lamb body long fastest-rising period; From birth to 75 ages in days are lamb weight fastest-rising periods.Though now the lactation amount of ewe is also high, nutrition is also fine, and lamb early will open food, trains the material that pastures, to promote that glandular stomach is grown, and the source had additional nutrients.General from after 10 ages in days to grass, tender for children green hay being bundled into being hung in aerial, allowing lamb eat from origin.Life starts to train material feeding for latter 20 days, puts half wet feed after scalding with boiling water in feed trough, and guide lamb to go to gnaw, lamb will eat for several times repeatedly.

Milk, grass transitional period (wean of two monthly ages at monthly age to four): along with the increase of age in days, lamb is arrived on grazing and herds.Mothers and sons separately herd and are conducive to increasing weight, fattening and Verminosis prevention, and the lamb of wean wants whole expelling parasite before turning group or sale.

. be bred as the feeding and management of sheep

Bleat young sheep or incubation sheep before breeding from weaning to.The period that this one-phase Shi Yanggu road and organ reach full growth, if nutrition does not catch up with, just can affect grow, physique, feed intake and fertility in the future.Strengthen cultivating, can physique be increased, promote the growth of organ, to improving meat ability in the future, strengthening reproductive performance and there is important function.Abundant nutrition and sufficient motion, young sheep chest can be made broad, and cardiopulmonary are flourishing, and physique is strong.To 8 monthly ages after wean, every day, supplementary feeding was containing the fine fodder 250 grams ~ 300 grams of digestible crude protein 15% on the basis of eating sufficient high-quality hay; To ewe more thin and weak after wean, on Ration formulation, to maintain based on normal metabolism, also to suitably have additional nutrients, to reach multiple fat.This every day in period every supplementary feeding mixed concentrate about 0.4 kilogram; Mixed concentrate is mainly mixing of 60 parts of corns and 25 dregs of beans.Also can less to fine fodder if herbaceous stem is excellent, male young sheep due to growth rate faster than young ewe, so give its fine fodder relatively many.Move even more important to male young sheep, be not only beneficial to and grow, but also can prevent from forming grass belly and pernicious habit.Routine weighing is bred as the mark that sheep grows degree of perfection, and raising must be noted that this index of weighing.Young sheep monthly fixedly should take a sample test body weight, so as to checking the developmental state of full group.Weigh before need not feeding in the morning or going out to herd and carry out.

Sheep hurdle manages

Sheep hurdle must establish feed trough and tank; To note during raising following some:

1. forage grass, feed, drinking-water will clean, and do not feed the forage that goes mouldy, forage grass can not be with water, and winter preferably drinks warm water.

2. keep sheep hurdle clean, dry, accomplish cool in summer and warm in winter, ight soil will often be swept.

3. to do twice epidemic prevention in spring and autumn and regular expelling parasite well.

(1) annual March, September only inoculate 1 time with sheep tetrad seedling (enterotoxemia of sheep, the sudden subcutaneous ulcer of sheep, sheep enterotoxemia, lamb dysentery) to all sheep, latter 30 days ~ 40 days of ewe breeding sheep tetrad seedling inoculation, duration of immunity is half a year; Ewe is as missed season of preventing epidemic, and newborn lamb uses sheep tetrad seedling inoculation 1 time for 1 week after birth ~ 2 weeks, 6 months immune 1 time again, interval.

(2) sheep streptococcus aluminium hydroxide vaccine, after lamb first time injections more than 3 ages in days, within 14 days ~ 21 days, inject second time again, duration of immunity is half a year.

(3) goats contagious pleuropneumonia aluminium hydroxide vaccine, prevention goats contagious pleuropneumonia, equal injectable below 6 ages in days and more than 6 monthly ages, duration of immunity is 1 year.

(4) the weak malicious freeze-dried vaccine of continuous goatpox, prevention goat, sheep pox, duration of immunity is 1 year.

(5) the weak malicious freeze-dried vaccine of sheep infective running sore dermatitis, the contagiosity running sore dermatitis of prevention sheep and goat, duration of immunity 5 months.

(6) epizoa in control: parasite mainly contains acarid, tapeworm, gastrointestinal nematode parasites, Fasciola hepatica etc.Regularly carry out expelling parasite, generally quarterly carry out 1 time, preferably Albendazole and ivermectin use simultaneously.Detailed directions: sheep per kilogram of body weight takes Albendazole 15 milligrams orally, press the 0.2 milliliter of intramuscular injection of sheep per kilogram of body weight with the ivermectin injection of 0.1%, such drug combination has above-mentioned parasite kills effect preferably simultaneously.

4. do Yang Chang health at ordinary times, disinfection well, sheep excrement uses after wanting heap fermentation process.Disinfection is centre point and the guarantee of sheep raising field Biosecurity system.Meanwhile, be also supplementing of vaccine immunity and medical treatment defect, only have environmental Kuznets Curves, immunity, medical treatment and sterilization acting in conjunction, just can keep the environment clean, ensure that sheep only grows up healthy and sound, reduce disease harm.1:800 dilution that disinfectant adopts the conventional acid iodide 1:500 of Yang Chang to dilute or green power disappears is to personnel and production area spraying disinfection; The sterilization pool of admission passage adds sterilization prestige 1:500 dilution or the sterilization of caustic soda 1% thimerosal; Every day, appropriate supplement water-filling, changed weekly once; Dilute with Suhl 1:300 or delivery room of sterilizing with UV sterilizer, with the sick sheep isolation ward of 2% caustic soda dilution spraying disinfection; Flock of sheep sheep drinking water should clean nontoxic, without pathogen, meet the drinking water standard of people; The various vessel Suhl 1:300-500 of breeding sheep dilute spraying or soak strict sterilization.Strengthen sheep hurdle cleaning garbage disposal formula at ordinary times to do.

In addition, in order to ensure that the feed nutrition of breeding flock improves, setting up special grassplot is important measures, below sketches grassland and requires:

A, whole: must cut weeds in whole ground, turn over, Gai Di, suppression, again removal of impurities.Turning over should in December then, and at this moment soil is soft, moist, sprays glyphosate removal of impurities 1 time before ploughing, the ground suppression of lid in January next year, March again with sweet phosphorus removal of impurities 1 time, by the end of April rainwater gradually lower ground time sowing.
