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.

Intestinal Digestibility

Abstract Canola was created as a low erucic acid and low glucosinolate seed, to produce high quality oil for human consumption and meal for use in livestock feed. China is an important user of Canadian canola products (seeds, oil, and meal). The extraction of the oil from the seed produces a co-product called canola meal. This meal is rich in protein and is used as a protein source in animal diets. However, differences in the characteristics of the seeds, or processing methods during oil extraction may affect the quality of this co-product. Plus, the synthesis of tissues and milk is related to the amino acids available to the animal for absorption in the small intestine. This study aimed to determine if there are significant differences in the intestinal digestibility (in vitro) of CP and DM between canola seeds and meals from different companies in Canada and to determine if there are significant differences between them in Canada and China. The three-step procedure was applied on residues from a 12-hour rumen incubation in fistulated dairy cows to estimate the intestinal digestibility of CP and DM. There were significant differences (P < 0.05) for TDDM (Total digestible dry matter) and IDP (intestinal digestibility of protein) of the meals between countries. The samples from China had higher TDDM (83.76% versus 81.53%, P = 0.018), while Canada’s had higher IDP (68.51% versus 65.28%, P = 0.016). No significant differences were observed within countries. Based on the material analyzed during this study, it is safe to affirm that there are no significant differences in the digestibility of DM and CP between Canada and China. It was concluded that the quality of the canola seeds or meals produced in both Canada and China were similar when used in dairy rations. Key words: canola seeds and bio-processing co-products (meals, pellets), nutritional differences, dairy cows

Coconut Meal

ABSTRACT Coconut meal can be an affordable low-cost alternative to noble ingredients such as corn and soybean meal in sheep diets. The objective of this study was to evaluate the effects of coconut meal inclusions, when used as a corn and soybean meal replacement, on the intake, digestibility, and nitrogen balance of sheep diets. Twenty-four male Santa Inês lambs with body weights (BW) of 26.6 ± 3.2 kg were used in the study. The animals were housed in metabolic cages and distributed in a completely randomized block design, with three treatments and eight replications. The animals received a total mixed ratio of 30% roughage (elephant grass) and 70% concentrate. The animals were fed on two experimental diets with 11% and 22% coconut meal inclusion and a control diet (without coconut meal). Dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and non-fibrous carbohydrate (NFC) intake as a percentage of BW were negatively influenced by the inclusion of coconut meal. The ether extract (EE) intake increased but did not differ between the 11% and 22% coconut meal diets. Furthermore, the digestibility of DM, CP, EE, and ADF did not differ between the two evaluated diets. The inclusion of coconut meal reduced NDF digestibility and increased that of NFC. The level of inclusion of coconut meal in the diet must be based on the EE content in the meal; keeping the EE intake below 0.16% of the BW helped to avoid limited intake of feed.

The aim of the present paper Was to test the value of various plant extracts (yeast barm, mature walnut embryos, coconut meal, young spinach leaves and tomato juice) used as the complementary elements of White's mineral nutrient for the culture <i>in vitro</i> of generative apices of winter wheat, rape and wetch. The results showed that the generative apices of investigated planits had various nutritive requirements which point to the necessity of a careful selection of a specific nutrient for particular plant material.
