As part of the search for sustainability in production systems, systems of annual crops intercropped with tropical forage plants have recently been used for silage production. Therefore, in the present study we aimed to evaluate the dry matter yield, fermentative parameters and nutritional value of the silage of sorghum intercropped with Paiaguas palisadegrass in different forage systems and maturity stages in a crop-livestock integration system. The experiment was conducted at the Goiano Federal Institute (Instituto Federal Goiano), Rio Verde Campus, Goiás, Brazil, in a completely randomised design with four replications in a 5 × 3 factorial arrangement with five forage systems (monocropped sorghum, monocropped Paiaguas palisadegrass, sorghum row intercropped with Paiaguas palisadegrass, sorghum inter-row intercropped with Paiaguas palisadegrass and sorghum oversown and intercropped with Paiaguas palisadegrass) and three maturity stages of the sorghum (milky, soft dough and hard dough). The results show that for all sowing methods, the silages of the intercropping systems harvested in the hard-dough stage provide a higher yield per area than did the monocropped sorghum and Paiaguas palisadegrass. The intercropping of sorghum with Paiaguas palisadegrass in crop-livestock integration systems could become an important option for the production of silage because intercropping minimises the inconveniences resulting from the fermentation process of the silage of monocropped grasses and improves the quality of the silage. These findings show this intercropping method to be advantageous strategy for the production of supplemental roughage in addition to contributing to the formation of pasture after the crops have been harvested for ensiling.

Currently, mixed systems for growing annual crops with forage plants of the Brachiaria genus represent an excellent alternative for the cultivation of maize by using the area for agricultural and livestock farming, which provides higher income to the grower and sustainability to the agricultural systems of the Cerrado. However, little is known about the best means for sowing such intercropped plants. Thus, the objective of this study was to evaluate the agronomic characteristics of maize (Zea mays) as well as the productive and nutritional characteristics of Paiaguas palisadegrass (Brachiaria brizantha cv. BRS Paiaguas) as the second crop in integrated production systems. The experimental design used randomized blocks with four replications. The treatments consisted of the following forage systems: monocropped of maize, monocropped of Paiaguas palisadegrass, maize intercropped with Paiaguas palisadegrass in rows, maize intercropped with Paiaguas palisadegrass between rows, and maize with oversown Paiaguas palisadegrass. The results showed that intercropping of maize with Paiaguas palisadegrass does not interfere with the agronomic characteristics or grain yield of maize, regardless of the system that was adopted. Regarding the production of forage, low production of dry matter was found for Paiaguas palisadegrass oversown in maize, though the nutritional value was better. Intercropping maze and Paiaguas palisadegrass is relevant to integrated production systems, as it allows for of a third harvest in the same crop year, which maintains sustainability especially because a smaller arable area is used compared to conventional systems.

A system for rating the quality of hay by sight, touch and smell was designed and tested. Seven sensory criteria were defined and rated independently on a scale from one to nine in direct relation to their assumed nutritional merit. Hays of different quality were obtained from four grasses and two alfalfas, each harvested at six maturity stages. Each hay was rated independently by five judges. The ratings did not differ (P < 0.05) between judges, but significant differences and interactions occurred between crops, maturity stages, and sensory criteria.Each hay was fed to sheep, and its nutritional value was determined as the voluntary consumption of digestible organic matter (grams consumed daily per kg of metabolic size—weight0.75). The correlation between voluntary consumption and the ratings of the sensory criteria in each hay was generally significant (P < 0.01) for composition, growth stage, color and texture, but not for freshness, odor and cleanness. The three last criteria varied little in the hays studied; therefore, it could not be concluded that they were unimportant in sensory evaluation of hay in general.The variability in voluntary intake "accounted for" by ratings of the seven sensory criteria ranged from 59 to 90% in the different kinds of hay, and 65% when the hays were pooled. When the hays were rated by composition and color only, these criteria "accounted for" 48 to 77% of the variability in intake, but only 38% when the hays were pooled. Coefficients of variation from regression for the pooled ratings were 23% for the seven sensory criteria, 30% for composition and color alone, and 38% from the mean for all seven criteria.

Legumes, such as red and white clover, are potentially important constituents of low input, environmentally friendly beef production systems. However, the effects of grazing clover on the quality of beef have not been assessed fully. Important aspects of meat quality are shelf-life (colour and lipid stability), flavour and human nutritional value, all of which are affected by components of the animals diet such as antioxidants and fatty acids. Tissues from lamb finished on swards containing white clover were reported to contain more linoleic and a-linolenic acid and less eicosapentaenoic acid (EPA, 20:5 n-3) (Vipond et al., 1993) compared to animals grazing grass. The objective of this study was to determine the quality of meat from two beef breeds raised on grass or grass plus white or red clover.

Muscovy Ducks

This study was conducted to assess effects of production systems and sex on nutritional value and meat quality of native Malawian Muscovy ducks. One hundred twenty ducks were randomly assigned to either an intensive (IS), duck-rice integration (DR) or free-range (FR) production system. A starter ration containing 20% crude protein and a finisher containing 17% crude protein were fed to ducks in IS (1 to 4 weeks), and provided as a supplement to ducks in DR and FR (5 to 10 weeks). Feed and water were offered ad libitum. At 10 weeks of age, 16 ducks per treatment were selected randomly, slaughtered and chilled at 4 °C for 24 hours. Carcass temperature, pH and meat colour were measured at 45 min, and at 3, 6, 12 and 24 hours post mortem. Tenderness, cooking loss, proximate and mineral composition were determined 24 hours post mortem. Production system and sex had no effect on carcass temperature, pH and proximate composition of duck breast meat. However, production system affected tenderness and mineral composition of the meat and sex influenced moisture and tenderness. Males were moister and had less tender meat than females. Carcasses from ducks in the FR system contained more zinc, copper, manganese, and potassium, but less iron while those in IS had the lowest mineral content of the three production systems. Thus, DR can be adopted to improve the current FR system of native Malawian Muscovy duck production with supplementation to produce duck with acceptable mineral composition and better meat quality.

ABSTRACT: In dry regions worldwide, providing feed for ruminants has been a great challenge, with a need to use plants which contribute to the resilience of production systems. Maniçoba is seen as a potential forage resource in the Brazilian semiarid, being used as hay or silage to feed ruminants. This review summarized results regarding forage production of maniçoba, in addition to dry matter (DM) intake, productive performance, and quality of animal products obtained providing maniçoba based diets, when compared to diets composed by other roughages for goats and sheep. Considering the evaluated studies, the average yield of maniçoba varied from 367 to 1,592 kg DM ha-1, enhancing the forage yield by increasing plant fertilization and planting density. Diets based on maniçoba promoted similar or higher intake of DM and productive performance for goats and sheep, when compared to diets comprising other forage resources. The quality of animal products was also similar to the ones obtained with diets based on traditional roughages, such as Tifton 85 hay or spineless cactus. Therefore, maniçoba allows a forage production that may contribute to ruminant production systems in semiarid environment and promote productive performance and animal product quality compatible to the ones provided by traditional forage plants.

Background: Phytonutrients in peach fruits have health promoting antioxidants against various chronic diseases. However, there is no extensive data to show the nutritional values of Local peach cultivars after post-harvest treatments. Objective: Mainly this study was objective to determine the effect of calcium carbide on nutritional value and quality of fruits of Pakistani peach cultivars. Methods: The peach fruits were collected from three different peach orchids of KPK and the fruits were divided into 4 groups while 5th group was collected from local fruit shop. Each experimental group was treated with different concentration of calcium carbide whereas control group was not treated. The peel and pulp samples were oven dried and ground to fine powder separately. The elemental compositions were determined using Particle Induced X-ray emission and Pelletron Tandem Accelerator. Result: Sixteen elements were identified in peach fruits and the elements were Al, P, S, Cl, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, and Se. In peel, concentration of some elements increased or decreased after treatment with CaC2 while in pulp the conc. of nearly all detected elements was increased in treated samples. We found significantly high amount of heavy metals traces including As, Se, Co, Si, and P in peach fruits treated with CaC2. Interestingly, the presence of trichomes in peach skin prevents the transfer of these heavy metals deep into the pulp which was also verified by the elemental profiling of nectarines. Conclusion: Conclusively, the artificial ripening with CaC2 changed the nutritional value of peach fruits that has higher health risks if consume with the peel. According to our best knowledge, this is the first report that highlights the effects of CaC2 which deteriorate the nutritional value of peach fruits in Pakistan.

Type 2 diabetes has become one of the major health problems of the modern world. It is assumed that environmental factors have a significant impact on the development of the disease, and great importance is ascribed to the diet, which can be modified accordingly. The diet can exert prophylactic and therapeutic effects; changes in the diet in advanced disease can improve the quality of life of diabetic patients and minimise the risk of complications, which are the direct cause of diabetes-related death. Functional food, which has a potentially health-enhancing effect in addition to its nutritional value, has been increasingly recognised and required. Cereal products are crucial in diabetic nutrition. Their function can additionally be enhanced by fortification with compounds with proven hypoglycaemic effects. Pasta has a low glycaemic index and is a good carrier of fortifying substances; hence, it can be highly recommended in diets for diabetic patients.
