This study was conducted to evaluate the effects of Tenebrio molitor (TM) oil as a total replacement for palm oil and poultry fat in broiler chicken diets on growth performance, nutrient digestibility, pancreatic enzyme activity, selected blood parameters and the lipid fatty acid compositions of liver and breast muscle tissues. A total of 72 seven-day-old female Ross 308 broiler chickens were used. The birds were randomly distributed into three groups with 12 replicates each, using two birds per replicate for 30 days in metabolic cages. The basal diet was supplemented with 5% palm oil, poultry fat or TM oil. There was no effect (p > 0.05) caused by the dietary oil replacement on the birds’ performance and apparent nutrient digestibility. Liver size (p = 0.033), the concentration of hepatic triglycerides (p = 0.049) and total cholesterol (p = 0.048) were reduced by TM oil supplementation. Furthermore, TM oil supplementation increased n-3 and n-6 fatty acids (p = 0.006; p < 0.001, respectively) in breast muscle tissue. In conclusion, the use of TM oil in broiler chickens’ diets did not show any adverse effects on performance, nutrient digestibility and blood biochemical parameters. Moreover, TM oil supplementation improved the fatty acid profiles of liver and breast muscle tissues.

The aim of the study was analysed the effect of humic acids separately and humic acids in combination with phytobiotic as garlic and oregano powder on amino acid (AA) profile of the most valuable parts of Ross 308 chicken. A total of 200 pcs Ross 308 broiler chickens of mixed sex were randomly divided into 4 groups (n=50): control group (C) without supplementation, experiment group E1 (2% humic acids), E2 (80% humic acids and 20% garlic powder) and E3 (90% humic acids and 10% oregano powder). Fattening period lasted for 42 days and all groups were kept under the same conditions. After slaughter, the AA profiles of breast and thigh samples were determined. In comparison with control group, 6 out of 10 AA was significantly affected (p ≤0.05) by used dietary supplementation – Met, Cys and His in thigh and Leu, Phe, His and Arg in breast muscle. AA composition of breast muscle was positively affected mainly by humic acids and 10% oregano powder supplementation (E3), while thigh muscle by humic acids and 20% garlic powder (E2). The highest obtained AA in breast muscle was Leu (2.02 g.100 g-1) in E3 group and thigh muscle His (1.15 g.100 g-1) in E2 group (p ≤0.05). In conclusion, humic acids and 10% oregano powder supplementation (E3) elicited to the best AA profile of chicken breast muscle but also the worst AA profile in thigh muscle so the effect of such a supplementation is disputable. On the other hand, humic acids and 20% garlic powder supplementation resulted into slight increase of AA in both breast and thigh muscle (E2).

Lipogenic Genes

The effect of dietary 18:2n-6/18:3n-3 ratio (by the replacement of corn oil with linseed oil) on n-3 polyunsaturated fatty acids (PUFA) enrichment in breast muscle of broiler chickens and the expression of lipogenic genes were investigated. Broiler chickens were fed ad libitum with diets containing 5% corn oil (CO), 3.75% corn oil + 1.25% linseed oil (CL1), 2.5% corn oil + 2.5% linseed oil (CL2), and 5% linseed oil (LO) based on the basic diets, respectively. Dietary 18:2n-6/18:3n-3 ratio did not affect 42-day body weight and 0&ndash;42-day feed conversion efficiency (feed/gain, P &gt; 0.05) of broiler chickens, however, 5% linseed oil significantly increased 0&ndash;21-day feed conversion efficiency (feed/gain, P &lt; 0.05) and decreased breast muscle weight (by 16%, P &lt; 0.05) of broiler chickens. With the decrease of dietary 18:2n-6/18:3n-3 ratio, the enrichment of total n-3 PUFA, 18:3n-3, 20:5n-3, and 22:5n-3 increased linearly (P &lt; 0.01), while the enrichment of total n-6 PUFA and 18:2n-6 decreased linearly (P &lt; 0.01) in breast muscle of broiler chickens. Dietary corn oil increased the enrichment proportion of 20:4n-6 in a dosage-independent manner. Replacing 1.5% corn oil with linseed oil increased the enrichment proportion of 22:6n-3 (P &lt; 0.05), but continuing to increase dietary linseed oil could not further elevate its deposition. Real-time quantitative RT-PCR was used to determine the expression of the mRNA levels of related genes. Dietary PUFA had insignificant effect on the expressions of LPIN2, WD and tetratricopeptide repeats 1 (WDTC1) and △-6 fatty acid desaturase (FADS2) in both breast muscle and abdominal fat. The effect of dietary PUFA on the expression of LPIN1 gene showed clear tissue dependence. Equivalent adding of corn oil and linseed oil could up-regulate the mRNA level of LPIN1 in abdominal fat (P &lt; 0.01). This study demonstrated that decreasing dietary 18:2n-6/18:3n-3 ratio promoted the deposition of desirable n-3 long chain PUFA in the edible tissue and influenced the expression of LPIN1 in a tissue-dependent manner. &nbsp;

The Impact

Cold truck transportation is considered one of the most integral parts in a food processing chain. However, countless cases of product spoilage and food poisoning incidents have proven that temperature control during transport has been neglected. Literature on the impact of temperature during distribution is scarce. The objective of this study was to investigate the impact of various transportation temperatures and travel duration on the meat quality and microbial population of broiler chicken breast muscle. Sixty broiler chickens (42 days old) were slaughtered and eviscerated; they then had their breast muscles removed (each bird provided two breast muscle samples: left breast and right breast), which were wrapped in plastic film. All 120 packed boneless breasts (PBBs) were then placed at −18 °C for 24 h. After 24 h, the 60 PBB samples were subjected to transportation for 1 h at 4 °C (20 PBBs), 10 °C (20 PBBs), and 15 °C (20 PBBs) while the remaining 60 samples were transported for 5 h at 4 °C (20 PBBs), 10 °C (20 PBBs), and 15 °C (20 PBBs) before analyses. The samples transported at higher temperatures exhibited higher populations of coliform and Salmonella than those transported at lower temperatures. A significant impact of the transportation duration on the Salmonella population was only observed in samples transported at 4 °C for 5 h. However, a significant impact of transportation temperature on color was only recorded for the redness (a*) values, where the samples transported at higher temperatures exhibited higher redness (a*) values. Significant increases in lightness (L*) and yellowness (b*) values as well as decreases in redness (a*) and pH values were recorded in samples subjected to longer durations of transportation across all the temperatures observed in this study.

One of the most important aspects of animal nutrition is digestibility of ingested materials which has a direct relationship with the health status of an animal. The effect of different fish meal alternatives (maggot, termite, grasshopper and lizard meals) on nutrient digestibility and carcass characteristics of broiler chickens was investigated in this 56 days feeding trial. One hundred and fifty broiler chicks (Marshal breed) were used for the study. Birds were assigned into five dietary groups of 30 chicks each and further divided into three replicates of 10 chicks each. Five experimental diets were formulated to contain 5% fish meal, maggot meal, termite meal, grasshopper meal and lizard meal in treatments 1, 2, 3, 4 and 5 (tagged T1 , T2 , T3 , T4 and T5 ) respectively in starter phase, while fish meal was replaced with 2.5% maggot, termite, grasshopper and lizard meals in treatments 2, 3, 4 and 5 respectively in finisher phase. The chicks were allocated into the four diets in a completely randomized design and housed in a deep litter pen with feed and water served without restriction. Results from dry matter, crude protein, crude fibre, ash, ether extract and nitrogen free extract digestibility showed significant (P<0.05) differences in the test ingredients on birds. Dry matter digestibility ranged from 88.35% in birds fed T3 to 91.86% in birds fed T5 . Crude fibre followed the same trend with the lowest (70.80%) in T3 and the highest (84.83%) in T5 , but ether extract digestibility was at the opposite trend where birds fed T3 had the highest (87.14%), and those on T5 gave the lowest (80.86%). Crude protein showed significant decrease across the treatments from 86.10% in T1 to 80.88% in T5 . Ash digestibility ranged from 68.84% in T2 to 77.05% in T1 . Results on cut-up parts showed that there were no significant (P>0.05) influence on all the parameters considered except in live weight, dressed weight and breast muscle weights where there were significant (P<0.05) differences. Internal organ proportions of the broiler birds showed no significant (P>0.05) effect of the test ingredients on all the parameters considered except in abdominal fat. It can be concluded that crude protein digestibility, live weight, dressed weight and breast muscle values in birds fed T2 (maggot meal) were higher than birds fed other test ingredients and as such recommended as an alternative to fish meal.
