Many farms in Colombia use animals to transport materials. The tree types of animals used in this project are horses, mules and donkeys. Farms must take into consideration the animal’s health, giving them time to rest. Because of this we can say that the more time the horse, mule or donkey requires to rest, the less time it can work. In this project I will demonstrate that not all three animals can resist the same. HYPOTHESIS
If load and time increase then the PH of the horse, mule or donkey sweat must increase. The higher the PH of the horse the more tired it is. Time is constant for all three animals and the load increases 2 kilos every round. There were 4 rounds. EXPERIMENT
Since before the experiment all three animals were treated the same. They were fed the same amount and at the same time. They were bathed at the same time and all other conditions were the same. When the horses were taken for the experiment they were all prepared at the same time. The experiment was done from 10 am to 1:30 pm for two days. The weight that the animals carried was first of 0 kg and it increased by 2 kg per trial up to 8 kg. We measured the PH with filter paper that was placed in cabbage ink. You must leave the paper to dry for 1 hour and then you can place the horse sweat in it. After you have the sweat in the paper you can see the color that it changed into and that would be the PH. For trial 0 the PH is always 8 because the color of the paper that corresponds to the cabbage. The first trial was with 25% of the weight. In the second trial the weight was 50%. In the third trial it was 75% and for the last trial the weight was at the maximum. Each animal could rest for 10 minutes between the trials of the other animals. Each animal did each trial 10 times. The results of each trial were averaged to see the resistance of the animal. RESULTS
From this project I learn that the mule is the animal that you can use in your farm to transport things. This project showed...
