HI ya
here is some info for ya i have not had a lot of time to look for ya yet.i got this off a farm site one guys idea of calf rearing
I have been rearing bought in calves for about 20 years now (approx 100 per year) - and over that time have accumulated a folder about 3 inches thick on methods etc of so doing. There is a vast amount of literature out there on calf rearing - most of it good stuff but also a lot with varying degrees of commercial bias. From all this and my own experience I believe some basic principles can be identified that are essential no matter what system is undertaken. As follows;
[1] The KISS principle - Keep It Simple Stupid. By far the best and easiest way to rear a calf is to leave it on its mother - (ask any beef breeder). Unfortunately its also the most expensive and least efficient. Next best would be multiple suckling on nurse cows, then ad lib feeding on warm milk, then restricted feeding, then cold milk, then milk replacer, then limited replacer plus meal and so on. The point is that the further you get away from the natural system and the more artificial you get the more things can go wrong and the more likely it is that they will go wrong - and when things start going wrong with calves, problems compound rapidly. Once calves start going back its a real struggle to get them going forward again - and the more artificial the system the harder it is likely to be.
[2] If it aint broke don't try to fix it. If you have developed a system that works well for you and delivers a good end product stick with it - don't make big changes for the sake of saving a few dollars - mistakes in trying something radically different could cost far more than potential savings. Over the years I have developed a system that works well for me that will consistently take a 40 - 45kg week old calf to 100kg in 12 -14 weeks, on approx 1 bag of milk replacer and 1.5 bags (60kgs) meal. With the certainty that my system can and will deliver I can thus budget my performance, costs, and profits with confidence. For the coming season I am expecting a bag of powder to cost $90, 60kg meal $45, and the calf $100. I anticipate my 100 kg plus weaner to be worth $400 in November - I reckon $100 kg profit per calf is required to make the job worth while. I am obviously going to be well above that with my proven system, even when all the extra smaller costs are also taken into account. So why embark on an unfamiliar, minor cost cutting exercise?
[3] BASIC REARING PRINCIPLES;
[A] Select only big, healthy calves. Minimise stress when transporting and rest them in the new environment for at least 8 hours before feeding. It is absolutely essential that the newborn calf receives colostrum - preferably within 6 hrs - certainly within 10 hrs - after birth. Volumes or percentage of liveweight recommendations for this vary a bit - in practice one good gut full and a contented calf is a good enough guideline. [C] Provide adequate nutrition - both quality and quantity. Good quality hay and meal should be available ad lib from week 1. [D] Keep calf dry at all times and draught free. Wind and wet separately are bad for the calf - dramatically increasing maintenance feed requirements. Together they are deadly. A shivering calf is a very bad sign. [E] Provide clean water with easy ad lib access from day 1. [F] Provide clean and dry flooring and bedding. Don't use tanalised sawdust or shavings. Top up with fresh stuff regularly as required. [G] Don't overcrowd. At least 1m2 per calf - especially if they are to be kept inside 24 hrs a day - preferably 1.5m2. Keep batch sizes down if inside permanently - maximum 20 per pen and don't shift calves between groups. [H] Bring the milk to the calves - not the calves to the milk. Observe good hygiene all the time.
