It should be noted that the mode of the calf feeding acidifying milk of the production white veal mentioned in the present invention can pass through two ways:First is free choice feeding, and second is the close free choice feeding rule of feeding rule that calf is made by artificial control, such as, in morning 4~5 point, carry out first time feeding, and feeding amount is 0.5~1kg;In morning 6~7 point, second feeding is carried out, feeding amount is 1~2kg;In the morning 9~10 point, third time feeding is carried out, feeding amount is 1~1.5kg;, carry out the 4th feeding at 12~13 points at noon, feeding amount is 1~2kg;, carry out the 5th feeding at 15~16 points in the afternoon, feeding amount is 1~1.5kg;, carry out the 6th feeding at 18~19 points in the afternoon, feeding amount is 1~2kg;, carry out the 7th feeding at 21~22 points at night, feeding amount is 1~1.5kg;In night 23~24 point, the 8th feeding is carried out, feeding amount is 0.5~1kg.
The essence of wherein above two form is " the hungry period " eliminated during calf feeding, calf is set to be constantly in the state of full abdomen, so as to the growth situation for keeping calf optimum, the production method that the present invention is provided, the calf that production white veal can be made grows fine, while make the protein content of beef increase, while fat content is reduced, it is below a kind of checking test of the production method of white veal of the present invention, specially:
The production method of white veal and the production method of general beef to provide the present invention does further contrast in terms of the growing way of calf and its composition of meat, and spy carries out following experiment.This Setup Experiments arranges 3 process according to different feeding methods, and contrast is implemented in 3 repetitions of per group of setting to calf in rate of body weight gain, four indexs of the protein content of beef and fat content.Specific experiment process record is as follows:
Experiment name:The calf index test and appraisal that acidifying milk is raised
Experimental period:2014 in Septembers, 6~2014 (totally 100 days)
Experimental subject:The birth Xia Luolai calves of 4 days
Process one:Daily according to the acidifying milk X18kg that obtained pH value in the feeding method feeding production method 1 of the offer of production method 1 is 5.
Process two:Daily according to the acidifying milk X28kg that obtained pH value in the feeding method feeding production method 2 of the offer of production method 2 is 6.
Process three:Daily feeding milk powder milk 8kg, milk powder milk includes 1kg milk powder and 20~30 DEG C of warm water 7kg.
First 3 days of the calf birth of 9 repetitions of guarantee are lived with cow, free choice feeding breast milk, and carry out feeding acidifying milk or milk powder milk in the same way from the 4th day, and every physical condition of wherein milk powder and calf house is consistent.
Experimental result:
It can be seen from table, the rate of body weight gain for processing the calf of one three repetitions is respectively 935.4 grams/day, 963.2 gram/day, 972.9 gram/day, average growth rate is 957.2 grams/day, the rate of body weight gain for processing the calf of three repetitions in two is respectively 910.4 grams/day, 917.8 gram/day, 909.5 gram/day, average growth rate is 912.6 grams/day, the rate of body weight gain for processing the calf in three is 872.2 grams/day, 856.5 gram/day, 880.7 gram/day, average growth rate is 869.8 grams/day, by contrast, the average growth rate of the calf for processing one and processing two is high than processing three calf rate of body weight gain.
The protein content for processing the white veal of one three repetitions is respectively 21.10%, 20.92%, 20.89%, average protein content is 20.97%, the protein content for processing the white veal of three repetitions in two is respectively 20.96%, 20.99%, 21.08%, average protein content is 21.01%, the protein content for processing the white veal in three is 1.19%, 1.20%, 1.18%, average protein content is 1.19%, by contrast, the average protein content of the white veal for processing one and processing two is high than processing the protein content of three white veal.
The fat content for processing the white veal of one three repetitions is respectively 1.13%, 1.12%, 1.16%, average fat content is 1.14%, the fat content for processing the white veal of three repetitions in two is respectively 1.15%, 1.16%, 1.17%, average fat content is 1.16%, and the fat content for processing the white veal in three is 1.19%, 1.20%, 1.18%, average fat content is 1.19%, and by contrast, the average fat content of the white veal for processing one and processing two is low than processing the fat content of three white veal.
It follows that, the calf pathogenicity rate that the relatively common method of calf that the production method of the white veal provided using the present invention is cultivated is cultivated is low, weightening is fast, and the beef of production is the beef protein content height that white veal compares ordinary powdered milk feeding, and fat percentage is low.
In addition, being found based on substantial amounts of experimental result, when the PH of milk is acidified between 5~6, preferably, meat composition is most delicious for the growing way of calf, and because experimentation is complicated, data are huge, and experimentation is not showed that in this patent.By analysis, this is likely due to when the PH of acidifying milk is to be between 5~6, and the intestinal environment in calf body is optimum, and when formic acid and Fructus Citri Limoniae, hyper acid, when the PH of acidifying milk is less than 5, the reduction of the digestive enzyme in calf intestinal can be caused, so as to affect to digest and assimilate, the growing way and health of calf is further affected, when formic acid and Fructus Citri Limoniae, hypoacidity, when the pH value of acidifying milk is more than 6, can cause that the pernicious bacteria in calf intestinal eliminates not thoroughly, cause to suffer from diarrhoea and fatality rate.
In addition, there is experiment to prove, calf is fed using the free choice feeding mode under naturalness, " the hungry period " in general feeding can be eliminated, needed for agreeing with the growth of calf to greatest extent, there is related data to show, 1% or so is higher by than the calf of normal feeding through the rate of body weight gain of the calf of practical feeding.
In sum, the white veal of the method production provided using the present invention effectively improves beef meat, its mouthfeel is more preferably, protein ratio is high, simultaneously fat content is low, can more meet the sense of taste of people's utility beef and the demand of mouthfeel, and the weightening of calf is fast, growing way is obvious, with relatively high efficiency of supply.
