Comparative Study on Energy and Nitrogen Metabolism of Brahman Cattle and Sheep Given Ruzi Grass Hay with Different Levels of Soybean Meal

Abstract Dried distiller grains with solubles (DDGS) is a popular protein source in grow-finish swine diets to replace soybean meal. An experiment was conducted at the South Dakota State University commercial swine research facility to determine the effect of standardized ileal digestible (SID) Trp:Lys ratio in grow-finish swine diets containing 40% DDGS compared to a standard corn-soybean meal diet. A total of 1,170 pigs (38.6 ± 0.2 kg initial BW) were utilized in a 98-d trial (9 pens per treatment). Pens of pigs were randomly allotted to 1 of 4 DDGS dietary treatments providing SID Trp at 15, 18, 21, and 24% of Lys or a corn-soybean meal diet (18%). Diets were isocaloric, with lysine at 100% of the requirement. From d 0 to 82, increasing Trp:Lys ratio in DDGS diets improved (P < 0.01) BW, ADG, and ADFI with no effect on F:G. Pigs fed the corn-soybean meal diet had greater (P < 0.01) BW, ADG, ADFI, and F:G compared to the DDGS diets with the exception of the ADFI of the 24% Trp:Lys treatment. From d 82 to 98, increasing SID Trp:Lys in DDGS diets had no effect on performance. Overall (d 0 to 98), increasing SID Trp:Lys in DDGS diets increased (P < 0.02) final BW and ADG, but pigs failed to perform to the same degree as the corn-soybean meal diet. Increasing SID Trp:Lys in DDGS diets resulted in an increase in hot carcass weight (P < 0.01); however, diets containing DDGS had decreased (P < 0.02) hot carcass weight, dressing percentage, percent lean, and loin depth compared to pigs fed the corn-soybean meal diet. These results indicate that increasing the SID Trp:Lys in diets containing 40% DDGS improved performance in early grow-finish phases with no effect in late finishing, but performance was inferior to standard corn-soybean meal diets.

The study was conducted in the poultry field in the Animal Production Department/ College of Agriculture and Forestry/ University of Mosul, for the period from 18/ 2/ 2020 until 13/ 4/ 2020. The experiment aimed to study the effect of replacement different levels of sesame meal (SSM) as a protein source to replace soybean meal (SBM) on the productive performance and reproductive of laying quail, 360 quail birds (240 females and 120 males) were used, at the age of 49 days, distributed randomly into five treatments, each treatment with eight replicates, ( 9 birds in each replicate 6 females and 3 males). The treatments were as follows: the first was the control (0% SSM), the second, third, fourth, and the fifth replaced SSM by SBM with level (25, 50, 75 and 100%) respectively, feed and water was ad libitum during the trial period of 8 weeks. The results of the statistical analysis showed there is a significant statistical difference at a level (P≤0.05) in the fifth treatment (100% SSM) as compared to control and other treatments in total egg number, average egg weight, total egg mass, Hen day egg production percentage (% HD), feed intake, feed conversion ratio, fertility, and hatching percentage of total eggs, average weight of hatched chicks, and a significant increase in the embryo mortality. The results also showed a significant decrease at a level (P≤0.05) in the feed intake for the fourth treatment (75% SSM) compared to the control, while no significant differences were observed for the other treatments in all the studied traits. The results of this study showed the possibility of using sesame meal as a protein source at (75%) to replace soybean meal in laying quail bird diets.

SUMMARY The present study endeavors to determine the impact of the inclusion of licuri tart in the diet of finishing lambs, Santa Inês mestizos, by evaluating the economic parameters. For this purpose, a total of 44 lambs, including both uncastrated as well as vaccinated and wormed lambs, with an average age of six months and a mean body weight of 21.2 kg ± 2.7 kg, were employed. Initially, the lambs were fed on the diet which consisted of 40% Tifton-85 hay and 60% of a concentrated mixture, mainly composed of ground corn grain, soybean meal, mineral premix, being further followed by the inclusion of the licuri cake at four different levels (a) 0.0, (b) 8.0,(c) 16.0, and (d) 24% with respect to the dry matter. Principally, the soybean meal and milled corn were replaced by the licuri cake with these levels, thereby constituting four treatments and 11 replicates (11 lambs per treatment) in a completely randomized design. Further, for subjecting the lambs to the above mentioned four different levels of treatment, the lambs were confined for 70 days. The analysis of various economic parameters revealed that upon including the licuri cake up to the level of 24%, the operation cost decreases, which in turn results in higher profitability. However, its cost at the time of use will eventually determine its use for feeding lambs, because of the possible price variations of the ingredients used to formulate the diets along with the model of production of the rural property.
