# Effects of waste-based concentrates from broiler farm on physico-chemical qualities and blood profile of landrace pigs

## TL;DR

This study found that using 12% waste-based protein concentrate from broiler farms in pig feed maintains meat quality and blood lipid levels similar to standard feed.

## Contribution

The novelty lies in demonstrating that moderate inclusion of broiler farm waste protein in pig feed does not compromise meat quality or blood lipid profiles.

## Key findings

- 12% CP-CH concentrate maintains meat quality similar to control feed.
- 24% CP-CH concentrate significantly reduces meat quality parameters.
- CP-CH inclusion does not affect blood lipid profiles in pigs.

## Abstract

The study aimed to determine the effect of giving concentrate protein from closed-house (CP-CH) broiler farm waste in rations on the meat quality (physical-chemical) and blood profile of landrace crossbreed pigs.

The study used a completely randomized design (CRD) with 3 treatments and 4 replications with 12 finisher-phase landrace pigs with an average body weight of 63.42 ± 2.39 kg. The treatments were: A (control): use of 0% CP-CH + 24% CP-152 concentrate; B: 12% CP-CH + 12% CP-152 concentrate; and C: 24% CP-CH + 0% CP-152 concentrate. The research parameters were meat quality (physical-chemical meat) and blood lipid profile [total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglycerides (TGs)].

The results showed that treatment group B obtained physical meat quality (pH, drip loss, cooking loss, and water holding capacity) and meat chemical quality (moisture, protein, fat, and ash content) that were almost the same as the control (p > 0.05). By administering 24% CP-CH + 0% CP-152 (C) concentrate, there was a significant decrease in the physical and chemical quality of crossbreed landrace pigs (p < 0.05). Administration of CP-CH at 12%–24% did not affect total cholesterol, HDL, LDL, or blood TGs in landrace-crossbreed pigs.

Giving 12% CP-CH (B) obtained meat quality (physical and chemical) almost the same as the control group. Treatment group C significantly reduced the physical and chemical quality of the meat. Administration of CP-CH at 12%–24% did not affect the blood profile of landrace crosses.
