Mục tiêu của nghiên cứu này là đánh giá khả năng sinh trưởng, thành phần thân thịt xẻ của 3 tổ hợp bò lai hướng thịt giữa bò cái nền Lai Brahman với các giống bò đực Charolais, Droughtmaster và Red Angus giai đoạn vỗ béo nuôi tại tỉnh Quảng Ngãi. Nghiên cứu thực hiện trên 18 bò lai (6 bò/tổ hợp lai) 18 tháng tuổi, thời gian nuôi 3 tháng. Kết thúc giai đoạn nuôi, 4 bò/tổ hợp lai được mổ để đánh giá năng suất thịt. Kết quả cho thấy, các tổ hợp bò lai Charolais × Lai Brahman, Droughmaster × Lai Brahman và bò Red Angus × Lai Brahman có khối lượng lúc 21 tháng tuổi lần lượt là 523,7; 465 và 484 kg/con, tăng khối lượng trung bình sau 3 tháng nuôi của 3 tổ hợp bò lai lần lượt là 1.282; 1.039 và 1.134 g/ngày. Khối lượng thịt xẻ (kg/con) và tỷ lệ thịt xẻ (% khối lượng giết mổ) tương ứng với các tổ hợp bò lai Charolais × Lai Brahman, Droughmaster × Lai Brahman và bò Red Angus × Lai Brahman lần lượt là 312,6; 275,6 và 295,5 kg và 60,6; 60,3 và 62,1%; Tỷ lệ thịt tinh của ba tổ hợp bò lai lần lượt tương ứng là 45,2%; 43,9% và 42,6%. Trong 3 tổ hợp lai thì xu hướng năng suất thịt xẻ của tổ hợp bò lai Charolais × Lai Brahman là cao nhất, tiếp đến là bò lai Red Angus × Lai Brahman, thấp nhất là bò lai Droughtmaster × Lai Brahman. Các tổ hợp bò lai hướng thịt này nên được nhân rộng tại Quảng Ngãi và các địa phương có điều kiện chăn nuôi tương tự. ABSTRACT The objective of this study was to determine growth performance, carcass composition of 3 beef crossbreds between Brahman crossbred cows and Charolais, Red Angus or Droughtmaster bulls in Quang Ngai. A total of 18 crossbred cattle (6 head/crossbred genotype) were used for fattening from 18 to 21 months of age. After the fattening period, 4 most representative cattle per genotype were slaughtered to evaluate meat performance and carcass composition. The results showed that Charolais × Lai Brahman, Droughtmaster × Lai Brahman and Red Angus × Lai Brahman crossbred cattle had a body weight of 523.7, 465.0 and 484.3 kg at 21 months old, respectively, average daily gain in fattening period of 3 beef crossbred genotypes were 1282, 1039 and 1134 g/day, respectively. The carcass weight and percentage of Charolais × Lai Brahman, Droughmaster × Lai Brahman and Red Angus × Lai Brahman were 312.6, 275.6 and 295.5 kg and 60.6, 60.3 and 62.1%, respectively. The percentage of meat of three crossbreds was 45.2, 43.9 and 42.6% body weight, respectively. Charolais × Lai Brahman had the highest beef performance, then Red Angus × Lai Brahman, and last was . These results could be concluded that the three crossbreds should be raised in Quang Ngai and other localities with similar farming conditions.

The last nutrient management review of black pepper was done in 1968. There is, therefore, a need to develop new technology to improve pepper production and transfer that technology to production site. This experiment was carried out to study the effect of newly developed biochemical fertilizer on some physiological characteristics, yield and soil fertility of pepper. The treatment consisted of T1 (BS): chemical fertilizer (N:12%, P:12%, K:17%); T2 (BK1): biochemical fertilizer F1 N:15%, P:5%, K:14) and T3 (BK2): biochemical fertilizer F2 (N:13%, P:4%, K:12). The biochemical fertilizer F1 out-yielded chemical and biochemical fertilizer F2 by 75.38% and 16.45% respectively with the higher yield being associated with various phonotypical alterations, which are reported here. Significant measureable changes were observed in physiological processes and plant characteristics, such as large leaf area index, more chlorophyll content and high photosynthesis rate coupled with lower transpiration rate in biochemical fertilizer F1(BK1) treatment compared with other treatment. The high fertility level in biochemical fertilizer F1 and biochemical fertilizer F2 (BK2) reflected the important of organic material in improving soil quality. In conclusion, the achieve high growth performance and yield in pepper, chemical fertilizer alone is insufficient whilst combination of organic and inorganic fertilizer with balance nutrient content gave a significant increase in yield and growth of pepper.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Intestinal Digestibility

AbstractThe aim of this study was to determine whether dietary supplementation with zinc oxide nanoparticales (NP-ZnO) as a substitute for the conventional ZnO affects the intestinal digestibility of selected minerals, growth performance and meat quality in turkeys. The replacement of ZnO with NP-ZnO had no effect on the intestinal digestibility of Zn, Cu, Fe and Ca, whereas the lowest dose of supplemental Zn reduced Zn digestibility. The applied inclusion levels and sources of Zn had no effect on the growth performance (except the feed intake) of turkeys, including liveability. No differences in the relative weights of the heart, spleen and bursa of Fabricius (except the liver), or the weights of the femur and tibia were found between the dietary treatments. Neither the dose nor the source of supplemental Zn influenced carcass dressing percentage or the share of breast, thigh and drumstick muscles in the carcass. In comparison with the highest and moderate doses of Zn, the lowest inclusion level of Zn contributed to increased yellowness of breast meat (P=0.005). The analyzed doses and sources of supplemental Zn exerted varied effects on the redox status of fresh and frozen breast meat. In conclusion, the growth performance of turkeys, carcass yield and composition as well as the redox status of fresh and frozen breast meat were generally similar, regardless of the dietary source and level of Zn. The beneficial effect of Zn addition at 100 mg/kg was improved Zn and Ca digestibility, and increased redness of breast meat.
