We studied the effect of inclusion crude protein (CP) and energy concentration in the diet on growth performance, gastrointestinal tract (GIT) traits, and carcass weight in broilers from 0 to 42 d of age. The experimental design was completely randomized with six diets combined as a 2 x 3 factorial with two levels of CP (20 vs. 22%) and three levels of energy (2900, 3000, and 3100 kcal/kg). Each treatment was 4 replicate and the experimental unit was a pen with 20 birds. All diets were based on corn, soybean meal, wheat, and included sunflower oil. For the entire experiment, the inclusion of CP in the diet did not affect growth performance and the other variables studied. From 0 to 42 d of age, increase energy concentration up to 3100 kcal/kg in diet tended to reduce average daily feed intake (ADFI) (P = 0.053) and improve feed conversion ratio (FCR) (P < 0.01) than energy concentration at level of 2900 kcal/kg. However, average daily gain (ADG) was not affect. Most of the benefits of increase energy concentration on broiler growth was observed from 14 to 21 d and 28 to 35 d of age, a period in which energy concentration improved ADFI and FCR (P < 0.01), respectively. On d 42, increase energy levels in the diet did not affect GIT or carcass relative weight, except for the liver relative weight was heavier (P < 0.05) when intermedia energy concentration 3000 kcal/kg was included in the diet. It is concluded that energy concentration were well utilized by broilers, at level of inclusion.

There are significant differences in efficiency for the second, third fourth and treatments (P≤0.05) on the first treatment. food conversion. It was in those qualities.
Adding a mixture of (Cr-Met and Zn-Met) led to a significant (P≤0.05) increase in insulin concentration over the rest of the treatments, while the first treatment recorded a significant (P≤0.05) increase in cortisol concentration in lambs’ blood over the rest of the treatments. Significantly (P≤0.05) the two treatments (T2 and T3) over the rest of the treatments in the concentration of thyroxine (TSH), and the addition of Cr-Met recorded a significant increase (P≤0.05) over the rest of the treatments in the concentration of thyroxine (T4). It was noticed a significant decrease (P≤0.05) in the treatments (T2, T3, T4) compared to the control treatment (T1) in the concentration of threonine (T3). The length of the treatment period and the interaction between the periods and the treatments had a significant effect on these characteristics.

One of the most issues that face the food production industries is the manufacture of healthy food products without synthetic preservatives due to the fact that artificial antibacterial agents and chemical additives could have serious detrimental impacts on people's life quality. Essential oils (EOs) extracted from various plant origins have received huge attention because of the possible health benefits. Essential oils are complicated combinations made up of numerous distinct chemicals isolated using various methods. Such chemicals demonstrated substantial biological functions like antioxidant and antibacterial activity through a variety of mechanisms, and they are less dangerous and pose no health problems to humans. In this article, we underline the importance of Essential oils such as major ingredients and sources, antibacterial activities, and potential uses in the food sector. The use of natural additives is becoming more common; nonetheless, they may have negative effects on organoleptic properties. As a result, more research is needed to adjust the dosages used to effectively stop the growth of microbes is still needed.

The aim of the current study was to assess the impacts of adding various levels of coriander (Coriandrum Sativum L.) on broiler production efficiency and ileal microflora. Five treatments, consisting of 90 ROSS (308) broiler chicks each, were created from a total of 450 broiler chicks that were one day old. Each therapy was applied three times (30 chicks per replicate).The experiment included five treatments: a control diet without coriander, a control diet supplemented with four levels of coriander powder (0.2%, 0.4%, 0.6%, and 0.8%). After 21 days, the value of final weight, weight gain, feed intake, and feed conversion ratio were increased significantly in the birds received diet that contained coriander compared with control. However, this trend was not significant in the day 35 and day 42 of experiment. These findings suggested that synthetic antibiotics might be replaced in poultry diets by natural feed additives and growth enhancers like coriander powder.

Science and industry are very interested in alternative pasteurization and sterilizing methods, like the direct electrical effect. An experimental batch ohmic heating unit was built and manufactured for this study. Our goal is to design and build batch Ohmic heating equipment that ensures adequate pasteurization of whole cow’s milk while also looking into the electrical phenomena that occur throughout the process. Ohmic and conventional heating technology were used to heat cow’s milk from 15 to 72°C. The temperature increased when ohmic heating was applied with varying voltage gradients (6.08, 9.56, and 19.13 V/cm), resulting in a substantial decrease (p≤ 0.05) in the heating time for milk pasteurization. The current that flows through the sample was higher at higher voltage gradients, which led to a quicker accumulation of heat. The change in electric current during ohmic heating of the milk is only dependent on the electrical conductivity when the voltage is constant. Ohmic heating induced a significant (p≤0.05) increase in system performance coefficient (SPC) values with increasing voltage gradients, resulting in heating rates (°C/minute).
