Effect of Diet Type Using Whole or Crushed Grains on Productive Performance in Awassi Lambs and Rumen Fluid Characteristics

Abstract

This study was carried out with the aim of knowing the effect of the type of diet using whole or crushed grains on the productive performance of Awassi lambs and the characteristics of rumen fluid.1/8 / 2021 for two periods, 18 male Awassi lambs, 4-6 months old, with an initial weight of 25 ± 10 were used in this experiment. It was divided into three groups, with six animals per group, and the first treatment (T1) was given concentrated feed by 2.5% of the animal’s weight in the form of whole grains and hay to saturation, and the second treatment (T2) used concentrated feed by 2.5% of the weight of the organism in the form of 50% Whole grains and 50% crushed grains and hay to saturation. The third treatment used concentrated feed 2.5% of the animal’s weight, crushed grains with hay to saturation. The results showed that there was a significant difference (p≤0.05) for the grain size provided in the coarse fodder consumption characteristic, as the first treatment that was fed whole grains was superior to the other treatments. There was a significant (p≤0.05) superiority of the periods on the daily and total weight gain, as the first period was superior to the second period. There was also a significant difference for the volume of grain provided on the daily weight gain, where the first treatment, which consisted of whole grains, was superior to the third treatment. Total weight gain, the first and second treatments were superior to the third treatment. There was a significant superiority (p≤0.05) for the interaction between the period and the grain size provided, as the interaction between the first period, the first feeding, and the second feeding was superior to the third feeding in terms of total weight gain. As for the level of the second period, a significant difference (P≤0.05) was found for the overlap between the second period and the first treatment in terms of daily and total weight gain over the third treatment. As for the level of overlap between feeding and periods, there was a significant superiority (P≤0.05) for the overlap between the period and the period. The first and the type of feeding in the daily weight gain and the total increase over the overlap between the second period and the type of feeding. There was a significant effect (p≤0.05) of the grain size provided on the rumen acidity (PH), where the first treatment was superior to the other treatments.
