Application of natural antioxidants for the formulation of functional meat products

There is growing interest in finding healthier meals that offer more than just nutritional benefits. Meat and meat products are consumed all over the world, so it is possible to use them as matrices to make sure that people get enough bioactive components from their food. Besides extending the meat product's shelf-life and improving its composition (by integrating antioxidant molecules), it could also help people stay healthy by lowering lipid oxidative products. In this review, we look at whether developing and eating functional meat products is a viable method for improving meat composition and stability and reducing the oxidative consequences associated with the consumption of meat intake. The inclusion of plant bioactive compounds and antioxidants in meat products should protect the composition and quality of functional meat and meat products as well as the customers' health status. The key plant components with antioxidant capabilities employed in the composition of functional meat products will be discussed in this review.

Carcass traits, blood parameters and meat composition of quail and pigeon available in Bangladesh

Common poultry birds like chicken, duck, quail and pigeon meat is gaining interest due to their genetic potentiality and management factors as well as special characters of their meat and egg. With a view to considers consumers demand, promising alternative bird farming and meat quality research, an attempt was undertaken to conduct a preliminary study to compare carcass characteristics, blood parameter, intestinal microbiology and meat composition of quail and pigeon of Bangladesh. The result revealed that, carcass traits, hematological parameters and intestinal microbiology did differ between quail and pigeon (P<0.05). The meat proximate composition data indicated that moisture and ether extract content did differ (P<0.05), however, crude protein and ash content did not differ between quail and pigeon (P>0.05). Thus, the preliminary study suggested that farmers can easily rear quail and pigeon for consumption of meat, however, further detail study can ensure detail physiological aspects and meat quality parameters of quail and pigeon.

Spaghetti Meat Abnormality in Broilers: Current Understanding and Future Research Directions

Spaghetti meat (SM) is a recent muscular abnormality that affects the Pectoralis major muscle of fast-growing broilers. As the appellative suggests, this condition phenotypically manifests as a loss of integrity of the breast muscle, which appears soft, mushy, and sparsely tight, resembling spaghetti pasta. The incidence of SM can reach up to 20% and its occurrence exerts detrimental effects on meat composition, nutritional value, and technological properties, accounting for an overall decreased meat value and important economic losses related to the necessity to downgrade affected meats. However, due to its recentness, the causative mechanisms are still partially unknown and less investigated compared to other muscular abnormalities (i.e., White Striping and Wooden Breast), for which cellular stress and hypoxia caused by muscle hypertrophy are believed to be the main triggering factors. Within this scenario, the present review aims at providing a clear and concise summary of the available knowledge concerning SM abnormality and concurrently presenting the existing research gaps, as well as the potential future developments in the field.

Effect of Rumen Protected Methionine and α-Tocopherol on Growth Performance, Carcass Characteristics, and Meat Composition of Late Fattening Hanwoo Steer in High-Temperature Seasons

This study was conducted to investigate the effects of rumen-protected methionine and α-tocopherol (RPMT) on growth performance, carcass characteristics, and meat composition of late fattening Hanwoo steers in high-temperature seasons. Fourteen steers were randomly assigned to one of two diets; control (commercial concentrate) and treatment (commercial concentrate + 20 g of RPMT). Average daily gain was 34% higher in the treatment group than in the control group; however, there was no significant difference due to the small number under investigation. Feed conversion ratio was lower in the treatment group than in the control group (p < 0.05). Supplementation of RPMT had little effect on the fatty acid composition of longissimus muscle. Metmyoglobin in the longissimus muscle was significantly lower in treatment group compared to the control group at the ninth day of storage (p < 0.05). The redness of the longissimus muscle was higher in the treatment group than in the control group on day 9 of storage (p < 0.01). Thus, the results suggest that RPMT have positive effects on growth performance, and Commission Internationale de l’Eclairage color stability in the longissimus muscle of late fattening Hanwoo steers in high-temperature seasons.

EFFECT OF RESTRICTED DIETS ON THE GROWTH AND MEAT COMPOSITION OF BROILERS

The trail on effect of restricted diets on the growth and meat composition of broilers was conducted at Department of Animal Nutrition, Sindh Agriculture University, Tandojam, Pakistan. fifty poultry feed ingredients were randomly selected and 30 least cost ingredients were purchased and analyzed for proximate analysis. After proximate analysis, three rations were formulated from 14 ingredients designated as Ration 1 (17% CP and 2900 ME), Ration 2 (21% CP and 2800 ME) and Ration 3 (24% CP and 2700 ME). After ration formulation, 45, day old chicks were purchased and reared for each ration for six weeks. Chicks of each ration were further divided in three groups i-e A, B and C having 15 chicks each. The chicks of each group were also divided in three replicates having 05 chicks. Group A was reared as control, group B was restricted to feed for 04 hours in brooding to rearing stage and group C was restricted to feed for 08 hours daily in brooding to rearing stage. Results revealed the initial weight of a day-old broilers was non-significant (P<0.05). Significantly higher (P>0.05) feed consumption (2218.74 g) was observed in group B2, water consumption 7095.3 ml , and final body weight 1134.76 g in B3 , weight gain 1086.61 g (B3), carcass weight 716 g (B3), dressing % 63.10% (B3), FCR 1.853 (B3). Significant (P>0.05) maximum meat moisture content 72.87% was noted in group B3, meat protein 13.77% in B3, fat % 4.78% in C1, and ash 1.85% in B2. The better per bird profit gain of Rs. 89.71 was recorded in B2. It was concluded that the broilers can be restricted their feed (containing 24% CP and 2700 ME) for 04 hours daily in brooding to rearing period for better growth and meat composition but per bird profit margin was low due to high cost of production therefore, broilers can be reared economically on ration 2 containing 21% CP and 2800 ME and their feed can be restricted for 04 hours daily.
