Investigating the Effects of Two Different Diets on Carcass and Meat Quality Traits of Chato Murciano Pigs

To test the effects of two diets, 40 castrated male pigs of the Spanish autochthonous Chato Murciano breed were utilised. Twenty pigs were fed a high protein/low fat (HP/LF) diet and slaughtered at 125.03 kg LW. The remaining 20 pigs were fed an LP/HF diet and slaughtered at 121.91 kg LW. The effects of diet on carcass and meat quality parameters were studied. Meat samples were collected using the Longissimus lumbar (Ll) muscle. The HP/LF diet resulted in a faster growth rate and more daily weight increase, as well as higher values of ultimate pH (pHu), colour parameters, and Ca, Mg, Zn, K, and Na content in the Longissimus lumbar muscle. Fe and Cu levels were greater on the LP/HF diet. There was a substantial difference in Ll muscle intramuscular fat (IMF) levels, with values of 3.21 percent in the HP/LF group and 11.00 percent in the LP/HF group; however, no variations in dorsal fat thickness measurements were observed. The IMF fatty acid compositions for the HP/LF and LP/HF groups, respectively, were 42.43 and 42.29 percent saturated fatty acids (SFA), 50.34 and 51.35 percent monounsaturated (MUFA), and 7.20 and 6.24 percent polyunsaturated fatty acids (PUFA), with only statistically significant differences in MUFA levels (P 0.05). The goal of this study was to see how two alternative diets (high protein-low fat vs. low protein-high fat) affected carcass and morphometric parameters, meat quality, and mineral and fatty acid composition in Chato Murciano pure pigs.

Investigating the Effect of Dietary Probiotics on the Growth Performance, Meat Quality Improvement of Broiler Chicken for Safe Meat Production

A feeding trial was conducted to examine the influence of Probiotic (Biofast) on broiler chicken’s growth output and meat quality. A nearby commercial hatchery obtained ninety-six 1-d-old mixed sexed Cobb 500 broiler chicks. In 2 experimental therapies, chicks were randomly assigned for 5 weeks. T1 care feed consumption was significantly (P > 0.05) higher than control at 0 to 3 weeks of age. While treatments failed to induce any marked effects on body weight, weight gain and FCR in the starting process, they increased numerically than control in T1. No major differences in body weight, weight gain, feed intake and FCR between the treatments were found in the finishing period (4-5 wks). Furthermore, although the dressing percentage was not substantially different, using Biofast was found to be a numerically higher percentage. Similarly, no substantial differences (p>0.05) between the treatments were observed in pH, cooking loss, meat colour and TBA values. In conclusion, dietary supplementation with Biofast does not have a substantial impact on the growth efficiency of broiler chickens, although it has some beneficial effects on other parameters that have indirectly been shown to increase broiler chicken meat quality as well as food safety problems.
