The Effect of Three Levels of Concentrate and Grain Processing on Feeding Behavior, Nutrient Digestibility, Blood Metabolites and Fecal pH Of Turkmen Horses.

Abstract: The aim of this study was to investigate, the effect of different levels of concentrates and grain processing on feeding behavior, nutrient digestibility, fecal pH and blood metabolites in the horse. Sixteen 5 to 11 years old Turkmen horses with an initial body weight 433±50 kg were used in this experiment based on completely randomized design. Four treatments were studied, in three treatments were used 20, 25 and 30% of concentrate containing processed grains (A20, A25 and A30, respectively), and in one treatment was used 25% of concentrate containing whole grain (B25). The amount of feed intake, chewing and swallowing rate and total intake for forage and concentrate were not affected by experimental treatments (P> .05). By increasing the concentrate level up to 30%, the digestibility coefficients of dry matter, organic matter, crude protein, ash-free neutral detergent fiber, ash-free acid detergent fiber and digestible energy increased. The highest digestibility coefficients were observed in A30 treatment (P< 0.05). The digestibility of organic matter, crude protein, ash-free neutral detergent fiber and digestible energy in A25 treatment significantly increased compared to B25 (P 0.05). The concentration of glucose increased with increasing concentrate for treatment A30 (P< 0.05). In conclusion, comparing the two levels of 25% concentrate showed that the use of processed grains compared to unprocessed grains had no effect on feeding behavior, fecal pH and blood parameters. The use of 30% concentrate containing processed grains improved digestion without adversely affecting feeding behavior and fecal pH.

The research article presents a study that investigated the impact of different levels of concentrates and grain processing on feeding behavior, nutrient digestibility, fecal pH, and blood metabolites in Turkmen horses. It found that increasing the concentrate level in horse feed up to 30% enhanced nutrient digestibility, and the use of processed grains did not affect feeding behavior, fecal pH, and blood parameters.

Research Methodology

  • A group of sixteen Turkmen horses, ranging from 5 to 11 years old with an initial average body weight of 433±50 kg, were selected for this experiment.
  • They were divided into four groups (treatments) based on a completely randomized design.
  • Three groups were given 20, 25 and 30% of concentrate containing processed grains (named A20, A25 and A30), respectively. The fourth group was given 25% of concentrate containing whole grain (B25).

Research Findings

  • The feed intake, chewing and swallowing rate, and total intake for forage and concentrate, showed no significant difference among the four groups.
  • As the concentrate level increased to 30% (A30), the digestibility coefficients of dry matter, organic matter, crude protein, ash-free neutral detergent fiber, ash-free acid detergent fiber and digestible energy augmented. The most significant increase occurred in the A30 group.
  • The quota of organic matter, crude protein, ash-free neutral detergent fiber, and digestible energy digested in the A25 group was substantially higher than that in the B25 group.
  • The concentrations of total protein, triglycerides, cholesterol, and low-density lipoprotein in the blood didn’t exhibit a significant variation among all groups.
  • The glucose concentration showed an increase with an increase in the concentrate for the A30 group.

Conclusion

  • The study concluded that the use of 30% concentrate containing processed grains in a horse’s diet can boost digestion without negatively impacting the feeding behavior and fecal pH.
  • Contrasting two levels of 25% concentrate showed that using processed grains instead of unprocessed grains had no significant influence on feeding behavior, fecal pH, and blood parameters.
