The objectives of this work were to evaluate the forage performance of several hybrids in relations with six checks. The farmer hybrids were realised by "Instituto Mexicano del Maíz", located at Saltillo, Coahuila. The agronomic traits taken into account were: grain yield and some chemical traits and their relationships with production and quality of forage in corn. Their work was divided in two parts, the first one under the field conditions in Gómez Palacio, Durango, (1992) where 25 hybrids were evaluated with a population density of 62,500 plants/ha. The analysis of variance showed no significance for production of green forage. However, one hybrid overcame the best check for more than 4 t. The second phase was carried out in the quality forage laboratory during 1992 - 1993, where each plant representing an entry was divided in three parts; later, a proximal analysis was performed and two variables were analized for green forage and ensilage. For percentage of fat, some experimentals hybrids had lower vulner than commercial hybrids in both green forage and ensilage, whereas for protein content six experimental hybrids overcame, the mean of the best checks. However, it is important to mention that the value was higher vulner of the entries for protein content were highest on ensilage than those shown for green forage whose group means were 6.91 and 6.12 respectively. In the other hand, it was posible to detect some experimental material with low vulner of fiber, mainly, in the phase of ensilage. We observed that the midde part of the plant was the richest for protein content in both ensilage and green forage. Finally, we observed the superiority of some experimental hybrids as for the parameters of contents of organic matter, portein, amount of ensilage and green forage.

1. 670 samples of the mixed milk from 15 herds were analysed, and the average percentages of total ash, soluble ash, insoluble ash, lime and phosphoric acid are given.2. Tables showing frequency distributions are also given, with the standard deviation, mean and probable error of mean for each constituent determined.3. Various correlations of these constituents with solids not fat and protein have been prepared, and these correlations are illustrated by graphs.It is observed that the total ash falls with the solids not fat until low values of solids not fat are reached, when the ash content appears to rise. This variation is confirmed by a curve illustrating the variation in ash content of samples of individual cow’s milk. Soluble ash rises as the solids not fat falls, but the insoluble ash shows a reverse variation. Lime and phosphoric acid both fall with the solids not fat.

The study investigated the characteristics of packaged water stored under ambient and sunlight conditions. This is with a view to testing the effect of prolonged storage under different storage conditions on its quality. In addition it analyzed the interactions between the parameters. Two packs each of bottled and sachet water was purchased from each factory at the point of production and ready for distribution to wholesalers. Twenty eight pieces of packaged water from each factory were kept at room temperature and the same quantity were kept under sunlight. Physico-chemical and microbiological analyses were carried out on the remaining packaged water within 24hrs. Half of the samples stored at the two storage conditions were removed for analysis at 3 weeks while the remaining half was analyzed after 6weeks. The physico-chemical characteristics were within the WHO recommended values except for the pH of some samples that have values in the acidic range of 6.2-6.48. All the physico-chemical values increased for samples kept under sunlight. All the water samples showed growth in faecal coliform (4-46 cfu/100 mL) and E. coli (0-13 cfu/100 mL) for samples kept under sunlight at three weeks and this growth increased to the sixth week. The presence of E. coli is an indication that the packaged water is not pure. Displaying packaged water under the sunlight and storing beyond 3 weeks by vendors have effect on the potability of the product. The regulatory bodies should raise awareness and ensure manufacturer have a quality control unit to test on a routine basis.

This study was carried out to assess the microbiological status of three hot meals served in eight selected school canteens of Mauritius, with two schools randomly selected from each of the four school zones of the island. Three individual samples of farata, panini, or fried noodles were collected at each school during two independent visits. The three individual samples of each food type collected during each visit were then pooled before being subjected to microbiological analyses. A total of 48 composite samples were analyzed. The parameters tested were Total Viable Count (TVC), Escherichia coli, Salmonella spp., Clostridium perfringens, Staphylococcus aureus, and Listeria spp. The microbiological analyses revealed that paninis were deemed as generally acceptable with TVC falling in the range of 3.0-5.7 Log CFU/g and undetectable levels of S. aureus and E. coli. In contrast, fried noodles and faratas harboured a moderately high level of TVC (4.4-6.7 Log CFU/g) and objectionably high levels S. aureus (3.1 to 5.0 Log CFU/g) and E. coli (3.1-5.1 Log CFU/g) for seven out of the eight schools.

Gelatin is an intermediate ingredient which is oftenly used in many field such as food, pharmacy, and cosmetics. It is usually extracted from pig and cow. Halal issue of gelatin sources and the outbreaks of mad cow diseases encouraged people to find an alternative sources of gelatin. One of the alternative sources of gelatin was duck bone. The aim of this research was to describe physicochemical properties of duck bone gelatin which is extracted by using acid extraction method as an alternative sources of halal gelatin. The extraction of duck bone gelatin used 5% concentration of HCl (hydrochloric acid). The extraction process consisted of four steps, they were degreassing, defating, demineralization, and acid extraction. The result showed that gelatin which was extracted from duck bone had these several characteristic: yield of 6.24%, pH 4.0, water content of 13.43%, ash content of 13.42%, protein content of 65.43%, and whiteness degree of 30.35%. Generally, gelatin which was extracted from duck bone had similar characteristic with commercial gelatin and SNI standard. Further researcher had been suggested to reoptimized extraction method in order to reduce ash content.
