Influence of Treatment of Specific Feed With Formaldehyde on Indicators of Rumn Metabolism and Biochemical Indicators of Blood In Lamb

Abstract

 The studies were carried out using the Latin square method on model fistula lambs with a live weight of 28-30 kg. All experimental animals were implanted with scar cannulas. The daily diet of group I consisted of 1 kg of alfalfa hay, 100 g of barley, 30 g of sunflower cake and 30 g of soybean meal (basic diet). Animals of the second group received the same diet, but the sunflower cake was treated with a 1% formaldehyde solution. The animals of the third group also received a basic diet and soybean meal treated with a 1% formaldehyde solution. It has been established that in animals that received sunflower cake and soybean meal treated with a 1% solution of formaldehyde in rumen fluid, the acidity decreases. This process most clearly occurs in lambs that received soybean meal treated with formaldehyde. VFAs are absorbed better in the body of lambs that received soybean meal treated with formaldehyde. In animals fed sunflower meal and soybean meal treated with formaldehyde as part of the diet, the concentration of ammonia in the rumen contents was lower than in the groups consuming the main diet.

Treatment of feed with formaldehyde slightly reduces the number of rumen microflora. However, this decrease was insignificant and did not lead to statistically significant facts. A significant decrease in the level of urea in the blood of animals fed sunflower cake and soybean meal treated with formaldehyde was established. It was also noted that there was an increase in the concentration of total protein in the blood of animals fed with feed treated with formaldehyde, a significant increase in albumin, and a significant decrease in the concentration of urea and creatinine.
