Description

A method to promote rapid growth of lambs by increasing the feeding amount and time interval of milk replacer and early weaning methods

technical field

The invention belongs to the technical field of animal husbandry and particularly relates to a feeding method for promoting rapid growth and early weaning of lambs by increasing the feeding amount and time interval of milk substitute powder.

Background technique

At present, my country's mutton sheep breeding industry is changing from free-range breeding to intensive and large-scale, requiring ewes to shorten the breeding cycle and achieve three productions in two years or two productions in a year on the basis of multiple births. There are generally two methods for raising lambs. The first method adopts the method of weaning after breastfeeding with ewes for 2 to 3 months. Lambs usually breastfeed with ewes for 2 to 3 months, which not only delays the reproductive cycle of ewes, but It is beneficial to the rapid reproduction of ewes and reduces the utilization rate of ewes. Moreover, under this feeding method, lambs rely on breast milk, resulting in insufficient intake of starter and slow rumen development, which is not conducive to fattening after weaning. On the other hand, due to postpartum weakness and postpartum diseases (such as: mastitis) and other reasons, the ewes have insufficient lactation, resulting in slow growth and even death of lambs, which directly damages the economic benefits of enterprises or farmers. The second method is the traditional milk replacer feeding method. Although this method can solve the problem of rapid breeding of ewes, usually the lambs need to eat milk replacer for about 60 days before weaning, which increases the production cost, and in the process of harvesting The growth and development of lambs are slow during the period of feeding milk replacer, which is not conducive to fattening after weaning.

Contents of the invention

In order to solve the above-mentioned problems existing in the prior art and actual conditions, the present invention provides a feeding method that promotes rapid growth and early weaning of lambs by increasing the feeding amount and time interval of milk replacer powder,

The lambs are breastfed with the ewes from 0 to 6 days after birth to ensure enough colostrum;

When the lamb is 5-6 days old, the breeder uses the feeding bottle to train the lamb to use the pacifier, so as to ensure the smooth transition of the lamb from eating breast milk to eating milk replacer;

When the lamb is 7 days old, the breast milk is weaned, and it is transferred to the lamb house and weighed. At this time, the lamb is completely fed with milk replacer. The amount of milk replacer is determined according to the weight of the lamb. One week's milk replacer feeding amount, and at the same time provide high-quality starter and clean drinking water for lambs to eat freely;

When the lamb reaches 35 days of age, the milk replacer is weaned.

Preferably, the crude protein content of the milk replacer is 23%, the crude fat content is 12%, and the daily feeding amount of the milk replacer is about 4% of the body weight of the lamb.

Preferably, the milk replacer is whole milk replacer.

Preferably, the crude protein content of the milk replacer is greater than or equal to 25%, the crude fat content is greater than or equal to 20%, and the daily feeding amount of the milk replacer is 2-3% of the lamb's body weight.

Preferably, the crude protein content of the starter is 20%±2%, and the NDF content is 18%±2%.

Preferably, the feeding method of the milk replacer is to dilute the milk replacer at a ratio of 1:4 with warm water at 60°C, and feed the lamb when it is cooled to about 40°C; , 20:00 and fed 3 times in total, with an interval of 6 hours between each feeding.

The present invention promotes the feeding method of rapid growth and early weaning of lambs by increasing the amount of milk replacer feeding and the feeding time interval, and adopts a high-intensity milk replacer feeding method (4% of body weight in grams) for lambs at the age of 7 to 35 days. /day), and adjust the amount of milk replacer feeding every week according to the growth of the lamb. Compared with the traditional feeding method of N grams/day, this feeding method can be adjusted in due course according to the growth of the lamb to fully meet the growth and development needs of the lamb. Increase growth rate. On the other hand, the liquid feed has a fast circulation rate in the gastrointestinal tract, and the purpose of promoting the intake of starter feed can be achieved through reasonable feeding intervals. Through this feeding method, the lamb can be weaned at the age of 35 days, the weaning weight reaches 11-13 kg, and the feed intake of starter is 150-200 g/day. The stress response after weaning is small, and the feed intake of pellets can reach more than 400 g/day within a week.

Beneficial effects of the present invention:

1. The feeding time of milk replacer powder is short, which can realize early weaning (35 days old) and reduce the cost.

2. The lamb grows fast, which is conducive to fattening after weaning.

3. Through a reasonable feeding strategy, the lambs can be promoted to feed pellets, promote rumen development, and be less affected by weaning stress.

detailed description

The present invention is a feeding and management method to achieve early weaning and fast growth of lambs by regulating early nutrition and feeding intensity. Ewes can quickly enter the next breeding cycle, improve ewe utilization, and reduce ewe feeding costs.

Example 1

The invention discloses a feeding method for promoting rapid growth and early weaning of lambs by increasing the feeding amount of milk substitute powder:

Lambs are breastfed with ewes from 0 to 6 days after birth to ensure enough colostrum.

When the lambs are 5 to 6 days old, the breeders use feeding bottles to train the lambs to use pacifiers to eat starters, so as to ensure the smooth transition of the lambs from consuming breast milk to consuming milk replacer. At this time, if there are lambs that cannot breastfeed due to weak ewes or diseases, they can be artificially fed, and artificially fed with milk replacer at 2% of the lamb's body weight per day, 4 times a day.

When the lamb is 7 days old, it is weaned from breast milk, separated from the ewe, transferred to the lamb house and weighed, and then the lamb is weighed every week to determine the amount of milk replacer for the next week according to the weight of the lamb. At this time, the lamb is fully used Milk replacer was fed, and high-quality pellets (about 20% crude protein, 18% NDF) and clean drinking water were provided for the lambs to eat freely.

Milk replacer preparation method: the crude protein content of the milk replacer is about 23%, and the crude fat content is 12%. It is recommended to use whole milk milk replacer to ensure the absorption and utilization of nutrients and reduce diarrhea in lambs; Lamb body weight formulate milk replacer, milk replacer feeding amount is 4% (gram/day) of lamb body weight, here can be the average value of week-age body weight of this group of lambs as a reference, according to the average value of lamb week-age body weight again Calculate the feeding amount of milk replacer for the next week; when preparing milk powder, ensure that the equipment used is clean and hygienic, do a good job of disinfection, dilute the milk replacer with 60°C warm water at a ratio of 1:4, and feed the lamb when it cools down to about 40°C .

Milk replacer feeding method: Milk replacer is fed 3 times a day, the recommended time is 8:00 in the morning, 14:00 in the afternoon and 20:00 in the evening, with an interval of 6 hours between each time to stimulate the lambs to eat pellets.

When the lamb reaches 35 days of age, the milk replacer is weaned immediately.

The invention is a feeding management method for early weaning and rapid growth of lambs by regulating early nutrition and feeding intensity.

The present invention promotes the feeding method of rapid growth and early weaning of lambs by increasing the amount of milk substitute powder fed and the feeding time interval, so as to realize early weaning of lambs (age 35 days), reduce feeding costs, and promote rapid growth and development of lambs; Promote pellet intake in lambs through sound feeding strategies.

Example 2

The invention discloses a feeding method for promoting rapid growth and early weaning of lambs by increasing the feeding amount of milk replacer. The difference between Example 2 and Example 1 is that the crude protein content is more than 25% and the crude fat content is more than 20%. The best milk replacer is fed three times a day at 2-3% of the lamb's body weight per day, with an interval of 6 hours each time, and a similar effect can also be achieved.

Test case

Comparing this method with the traditional milk replacer feeding method, select male lambs with the same age and similar birth weight, and feed them from 7 days to 49 days in a single pen, and the feeding group fed by this method is weaned at 35 days , The traditional method group was weaned, the lambs were weighed according to the age of the week, the average daily gain was calculated, and the pellet feed intake of the lambs was recorded every day.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still understand the foregoing embodiments The recorded technical solutions are modified, or some of the technical features are equivalently replaced.
