Dietary Treatments

A feeding trial was conducted to investigate the effects of Piper sarmentosum leaves (PSL) on meat quality of broilers. The 144 commercial broiler chicks, one day old, were randomly assigned to 5 groups with three replicate cages. The five treatments were: 1) basal feed (8 chicks/cage), 2) basal feed (10 chicks/cage), 3) basal feed supplemented with 1% of PSL (10 chicks/cage), 4) basal feed supplemented with 2% of PSL (10 chicks/cage), and 5) basal feed supplemented with 3% of PSL (10 chicks/cage). The duration of dietary treatments was 42 days. The results showed that the group supplemented with 3% PSL had higher redness, yellowness, and cooking loss than the control group with 10 chickens/cage (P less than 0.05). It was also observed that the 3% PSL treatment gave significantly lower lightness than the 0% and 1% PSL treatments with 10 chickens/cage (P less than 0.05). Overall, the study indicated that PSL might improve chicken meat colour and protect against protein oxidation, but it has no potential in protecting against lipid oxidation in broiler filet.

Variable Energy

Fats are important but variable energy-yielding ingredients in diets for broilers. One of the factors that may affect the dietary energy value of fats is the proportion of free fatty acids which, together with rate of inclusion of fat and the age of the bird, must be considered in fat evaluation. The current experiment was designed to investigate the effect of free fatty acid content of tallow on the apparent metabolisable energy values for broilers.Tallow and tallow acid oil (Table 1) were obtained for evaluation. Tallow (A) of free fatty acid content 138.4 g/kg was hydrolysed to produce a fat (E) of free fatty acid (FFA) content 952.1 g/kg. Fat A and B were blended in the proportions A75:B25, A50:B50 and A25:B75 giving fats of 341.5, 545.3 and 748.7 g/kg FFA respectively which were included at rates of 40 g/kg, 80 g/kg and 120 g/kg at the expense of the energy-yielding ingredients. The 16 experimental diets - basal (Table 2) together with 15 containing fats - were evaluated with Ross 1 broiler chicks of 1.5 weeks (5 replicates of cage of 2 birds) and 7.5 weeks of age (5 replicates of cage of 1 bird).

Metabolisable Energy

The term 'fermentable metabolisable energy' (AFRC, 1992) has been criticised as an index of the supply of fermentable energy to the rumen because it has not been measured directly, is insensitive to rumen outflow rate and assumes fermentation of some nutrients which bypass the rumen (Newbold, 1994). One alternative is to describe the content of fermentable energy in terms of the amount of gas evolved during fermentation by ruminal microorganisms. The automated pressure transducer technique of Davies et al. (1995) has been applied to individual concentrate feedstuffs to provide an alternative database of fermentable energy content (Baughan et al., unpublished).

Lipid And Protein Oxidation

It has been proposed that there is a correlation between high-fat diet (HFD), oxidative stress and decreased γ-aminobutyric acid (GABA) levels, but this has not been thoroughly demonstrated. In the present study, we determined the effects of strawberry extract intake on the oxidative stress and GABA levels in the frontal cortex (FC) of obese rats. We observed that an HFD increased lipid and protein oxidation, and decreased GABA levels. Moreover, UV-irradiated strawberry extract (UViSE) decreased lipid peroxidation but not protein oxidation, whereas non-irradiated strawberry extract (NSE) reduced protein oxidation but not lipid peroxidation. Interestingly, NSE increased GABA concentration, whereas UViSE was not as effective. In conclusion, our results suggest that an HFD increases oxidative damage in the FC, whereas strawberry extract intake may ameliorate the disturbances associated with HFD-induced oxidative damage.
