BEET GROWTH AND PRODUCTIVITY UNDER NITROGEN FERTILIZATION

Abstract

OVER TIME THE ESTIMATE OF THE WORLD POPULATION TENDS TO INCREASE, CONSEQUENTLY THE DEMAND FOR FOOD AS WELL. BEEF IS ONE OF THE MOST CONSUMED FOODS IN THE WORLD, SO CATTLE RANCHERS ARE LOOKING FOR WAYS TO INTENSIFY WEIGHT GAIN IN BEEF CATTLE TO MITIGATE PRODUCTION. THE USE OF INJECTABLE AMINO ACID AIMS TO CORRECT THE NUTRITIONAL DEFICIENCIES OF ANIMAL FEED BY INCREASING ITS WEIGHT GAIN. THE PRESENT STUDY AIMED TO EVALUATE WEIGHT GAIN IN NELLORE CATTLE AS A RESULT OF THE USE OF AN INJECTABLE AMINO ACID SUPPLEMENT. THE EXPERIMENT WAS CARRIED OUT AT FAZENDA RECANTO, IN THE STATE OF GOI�S, FROM OCTOBER TO NOVEMBER 2020. 60 RING-BRED ANIMALS WERE USED, DIVIDED INTO TWO BATCHES OF 30 ANIMALS EACH, ANIMALS FROM BATCH 1 RECEIVED THE TREATMENT WITH THE INJECTABLE AMINO ACID SUPPLEMENT. WHILE IN LOT 2 THE ANIMALS REMAINED AS A CONTROL, WITH THE SOLUTION NOT BEING APPLIED, ALL 60 ANIMALS WERE TAKEN TO THE PADDOCKS WITH BRACHI�RIA DECUMBENS PASTURE, WHERE PROTEIN MINERAL SALT WAS AVAILABLE IN A COVERED TROUGH. GIVING THE AVAILABILITY TO EVALUATE THE SOLUTION OF AMINO ACIDS IN THE ANIMALS UNDER THE SAME CONDITIONS. INITIAL BODY WEIGHT, WEIGHT GAIN AND AVERAGE DAILY GAIN WERE EVALUATED, THE RESULTS OF WEIGHT GAIN AND AVERAGE DAILY GAIN HAD A SIGNIFICANT DIFFERENCE BETWEEN THE TWO LOTS, THE ANIMALS IN LOT 1 (SUPPLEMENT) HAD A WEIGHT GAIN TOTAL OF 59.56 KG AND THE AVERAGE DAILY GAIN WAS 1.191 KG, WHILE IN BATCH 2 (TESTEMUHA) THEY HAD A TOTAL WEIGHT GAIN OF 29.2 KG AND THE AVERAGE DAILY GAIN WAS 0.584 KG. THEREFORE, THE APPLICATION OF THE AMINO ACID SUPPLEMENT INJECTABLE IN NELLORE CATTLE IMPROVED THE PERFORMANCE AND WEIGHT GAIN OF THE ANIMALS.
