A study looked at how feeding lactating cows a mix of wheat straw and mesquite pods affected their performance. They compared this mix to a traditional diet of roughage and concentrates. The cows that ate the wheat straw and mesquite pod mix had higher daily intake, protein, and energy compared to the control group. They also produced more milk, with the cows on the traditional diet showing the highest improvement. The milk quality remained consistent across all groups. Overall, the total mixed rations with wheat straw and mesquite pods improved the cows' performance, especially in milk production.
