香蕉副产物丰富的资源量,是一种非常规新型青贮饲料资源,对其研发利用可大大促进反刍动物的养殖规模,建立"南方牧场"有着重要的作用意义。作为一种非常规饲料开发利用,除了在青贮加工中要注重保持其营养成分,降低抗营养物质外,根据饲料营养特性形成与之配套的饲喂技术,降低养殖成本提高动物养殖经济效益,才能显现出非常规饲料开发的优势。为能够全面掌握香蕉副产物青贮饲料饲喂应用技术,开展了为期2年的香蕉副产物青贮饲料对不同品种和不同日龄的肉牛饲喂试验,旨在为完善香蕉副产物饲料化利用技术提供依据。结果表明:牛只采食量正常,健康状况良好;与牛只体重1%的能量型精料补充料配合饲喂对肉牛日增重效果明显,不同肉牛品种和牛龄间饲喂增重效果有一定差异,对安格斯牛、西门塔尔牛等杂交牛品种增重效果明显,日增重可达1.02kg/·d头以上,对云南本地黄牛日增重效果稍慢,日增重为0.48kg/d·头以上;对14月龄体重约250kg以上牛增重效果明显,日增重可达1.02kg/头·d以上。 相似文献

海参是我国传统药食两用的滋补佳品,具有高蛋白、低脂肪的特点,其富含的活性物质还具有良好的抗氧化、抗菌和抗肿瘤等多种生物学特性及药理作用。由于海参的主要食用部位为海参体壁,导致海参加工过程中产生海参肠、海参性腺等大量的副产物。除含有与体壁相似的成分外,海参副产物还富含海参多糖、海参皂苷、活性肽、各种活性酶类等多种物质,是天然动物饲料添加剂的潜在来源。但目前由于对海参副产物价值的忽视及饲料化工艺的落后,海参副产物大多被丢弃,造成严重的资源浪费及环境污染。本文主要综述了海参副产物的营养特性、饲料化利用技术、在畜禽生产中的应用前景,旨在为海参副产物的饲料化利用提供参考。 相似文献

1. Two experiments were conducted to determine the effects of level of inclusion of poultry by-product and enzyme-prebiotic supplementation on grower diet digestibility and the performance of broilers. 2. Six grower diets were formulated to provide a similar nutrient profile with the exception of using three graded levels of poultry by-product, namely 0, 25, 40 g/kg of the diet with and without supplementation of enzyme preparation at the rate of 1 kg per tonne of feed and prebiotic preparation at the rate of 2 kg per tonne of feed. The experimental diets were used from 3 to 6 weeks of age. 3. Body weights, feed intake and feed conversion efficiency were not affected by poultry by-product; however, enzyme-prebiotic had a significant positive effect on feed conversion efficiency at 0 to 6 weeks in experiment 1. 4. Crude protein digestibility was decreased by feeding the diet containing poultry by-product while ether extract digestibility was increased by poultry by-product at the rate of 25 g per kg of feed only. Dry matter retention, crude fibre digestibility and organic matter retention were not affected by poultry by-product. Dry matter and organic matter retentions, crude protein, ether extract and crude fibre digestibilities were not affected by enzyme-prebiotic. 5. Protein efficiency ratio (PER) values were increased by poultry by-product at the rate of 40 g per kg of feed and addition of enzyme-prebiotic. 相似文献

This study identified the indigenous criteria used by livestock farmers in urban and peri-urban areas of Kampala to assess the nutritional quality of available feed resources. Focus group discussions and questionnaire interviews (with a total of 120 livestock farming households) were conducted. The findings showed that banana peels, leftover food and own-mixed feeds were the most commonly used feed resources for cattle, pigs and chickens, respectively. Farmers use several indigenous criteria to judge the nutritional quality of the available feed resources. These included perceived effects on disease resistance, feed intake, growth/body condition, hair coat appearance, faecal output, faecal texture and level of production, among others. According to farmers, animals offered with a feed resource of good nutritional quality are more resistant to diseases, ingest much of the feed, gain weight with well-filled bodies, have smooth hair coats, produce large quantities of faeces that are not too firm or watery and exhibit good performance (lactating cows produce more milk, sows produce piglets of good body size, hens lay more eggs of normal size, etc.). Although this indigenous knowledge exists, farmers put more importance on availability and cost as opposed to nutritional quality when choosing feed resources. This explains why banana peels were among the feed resources perceived to be of low nutritional quality but, at the same time, were found to be the most commonly used. Hence, there is a need to sensitise farmers on the importance of nutritional quality in ensuring better and efficient utilisation of the available feed resources. 相似文献

Citrus pulp is classified as an energy concentrate by-product feed. Citrus by-products fed to beef cattle include citrus molasses, citrus meal, wet citrus pulp, dried citrus pulp, and pelleted citrus pulp; however, in current production systems, pulp (wet, dry, and pelleted) is the only by-product commonly used. Citrus pulp production in the United States is limited to specific subtropical regions, of which south central Florida remains the largest with additional production in California and Texas. 相似文献

This study aimed to evaluate the substitution of imported corn and soybean by local feed resources from tropical production settings such as entire green banana and Gliricidia sepium forage as energy and protein sources, respectively, in sheep diets. Two experiments were conducted: first, a ‘growth trial’ and second, an in vivo digestion study. In the ‘growth trial’, 40 Martinik lambs [body weight (BW): 29.4 ± 3.6 kg; 6 months old) were used and distributed into four groups of 10 lambs each according to treatment: HBGl (banana + gliricidia at low level; 1500 g/day; 119 g/kg BW0.75), HBGh (banana + gliricidia at high level; 3000 g/day; 238 g/kg BW0.75), HBS (banana + soybean cake) and Control (corn + soybean cake). In digestion trial, four Martinik rams (BW: 57.2 ± 3.45 kg) fitted with ruminal and duodenal cannulae were used; treatments (HBG, HBS and Control) were similar but adjusted to metabolic body weight (MW) and just one level of gliricidia was used. Intake, average daily gain (ADG), feed intake to gain index (F:G), apparent total and ruminal digestibilities as well as nitrogen balance, microbial efficiency and volatile fatty acid (VFA) profile were monitored. Lambs fed HBGh had greater dry matter (DM) intake based on MW and ADG (173 g/day vs. 141 g/day; p < 0.001), whereas HBGl lambs showed the lowest ADG (71.5 g/day) and the worst F:G (14.4; p < 0.001). The DM, organic matter (OM), neutral detergent fibre and acid detergent fibre digestibilities were not influenced by treatment, whereas crude protein digestibility was higher (p = 0.024) in diets offered banana or corn + soybean cake (687 g/kg DM and 658 g/kg DM, respectively). Ruminal DM and OM digestibilities did not differ among treatments. Total or individual VFA concentrations were also not influenced by the diet. Higher (p = 0.006) ruminal fluid pH values were recorded for diets combining banana and gliricidia (6.54) or banana and soybean (6.39) until 3 h after a meal. As all animals on gliricidia‐ and banana‐supplemented diets gained weight and maintained a positive N balance, it is concluded that green banana and gliricidia forage may be a viable alternative to replace conventional energy and protein supplements in sheep diets. 相似文献

Camelina sativa is one of various oilseed crops being studied for its potential value in biofuel production. The resultant by-product of oil extraction, camelina meal (CM), could be marketable as a livestock feed. Our study evaluated the potential use of CM as a feed ingredient in turkey poult starter diets. This was a pilot study to determine whether further work investigating inclusion of CM as a potential feed ingredient in turkey diets might be of value if a least-cost formulation warranted its integration. Results indicate that CM may be a potentially useful minor ingredient in turkey diets if economically feasible, but caution should be exercised in using CM above 5% of finished feed in a poult starter diet. In an appended test, similar weight gain and feed conversion were attained with a diet containing camelina oil as a replacement for vegetable oil compared with the control diet. 相似文献
