Lalleshwari, whether you like it or not, Manu Simrati, Srimad Bhagwatam, and Mahabharat are Sanatan scriptures. They speak out against animal consumption. But if it is Vedic texts as in the 4 vedas you want then you will be disappointed.
Please take a look at the following verses from the Vedas which speak for protection of animals and against meat consumption.
Protect both our species, two-legged and four-legged.
Both food and water for their needs supply.
May they with us increase in stature and strength.
Save us from hurt all our days, O Powers! Rig Veda Samhita 10.37.11. VE, 319
One who partakes of human flesh, the flesh of a horse or of another animal,
and deprives others of milk by slaughtering cows,
O King, if such a fiend does not desist by other means,
then you should not hesitate to cut off his head. Rig Veda Samhita, 10.87.16, FS 90
Those noble souls who practice meditation and other yogic ways,
who are ever careful about all beings, who protect all animals,
are the ones who are actually serious about spiritual practices. Atharva Veda Samhita 19.48.5. FS, 90
You must not use your God-given body for killing God's creatures,
whether they are human, animal or whatever. Yajur Veda Samhita 12.32. FS, 90
No pain should be caused to any created being or thing. Devikalottara agama, JAV 69-79. RM, 116
