Abstract:
ABSTRACTPurebred cows were evaluated for reproductive performance and live weight, and for pre-weaning growth and viability of crossbred progeny sired by unrelated breeds. The cows comprised three indigenous breeds, Mashona, Nkone and Tuli and four exotic breeds Africander, Brahman, Sussex and Charolais. Over 3 years, the mean calving rates % (s.e.) were 55·5 (3·0), 76·0 (3·8), 63·1 (4·5), 69·6 (3·5), 70·0 (3·8), 60·0 (4·3) and 67·0 (5·0) for Africander, Mashona, Nkone, Tuli, Brahman, Sussex and Charolais cows, respectively.Bos taurusand Brahman cows were heavier at parturition and at calf weaning than indigenous cows. Mashona cows were lightest at both stages. Calves ofBos tauruscows were heaviest at birth and those of Mashona lightest. Calves of Brahman cows had the most rapid growth rate and at weaning (240 days) weighed in kg (s.e.) 207 (3·1), compared with 184 (2·1), 172 (2·2), 187 (2·6), 184 (2·1), 178 (2·7) and 186 (2·9) for progeny of Africander, Mashona, Nkone, Tuli, Sussex and Charolais, respectively. Pre-weaning survival rates of the breeds were not significantly different but viability was higher in progeny of indigenous than exotic breeds. The productivity estimates combining calving rate, cow weight, calf weaning weight and pre-weaning viability demonstrated the superiority of indigenous breeds and the Brahman over Africander andBos taurusbreeds.

Abstract:
ABSTRACTCrossbred cows were evaluated for reproductive performance and live weight, and for pre-weaning growth and viability of progeny sired by seven unrelated breeds. They were also evaluated on overall productivity expressed as weight of weaned calf per cow mated per year, per 100 kg of cow per year and per 100 kg metabolic weight of cow per year. The cows comprised reciprocals of Africander with Mashona, Nkone, Brahman and Sussex, one-way crosses sired by Sussex out of Mashona, Nkone and Brahman dams, and by Charolais out of Africander, Mashona, Nkone, Brahman and Sussex dams. These represented sanga × sanga, sanga × zebu, Bos taurus × sanga, Bos taurus × zebu and Bos taurus × Bos taurus crossbred types. Bos taurus × zebu crosses were superior to other breed types for all the three productivity indices and for virtually all the individual components of these. There was little difference between the other four breed types in overall productivity of components of these. Differences between reciprocals were observed in sanga × sanga and sanga × zebu, cows with Africander dams being more productive than reciprocals with Mashona, Nkone and Brahman dams. The Bos taurus × Bos taurus cross was inferior in overall productivity primarily due to large cow weight and relatively low growth rate of progeny. Progeny sired by Friesian, Simmental and Brahman had higher weaning weights than those sired by Hereford, Aberdeen Angus, Africander and Tuli. Overall, heterosis was positive for all traits and averaged 0·15 for the three measures of cow productivity. Heterosis was three times higher in the Bos taurus × Bos indicus cross than in the Bos indicus crosses.

Abstract:
SUMMARYThe effects of year of birth, age of dam, sex of calf, month of birth and weaning age on weaning weights of Mashona calves on six commercial farms in Zimbabwe were estimated by least squares procedures from data of 6365 calves born 1977–85. The least squares mean weight at 205 days among farms ranged from 123 to 159 kg while the linear regression coefficients of weight on age ranged from 0·31 to 0·46 kg. Adjustment for weaning age by the average daily gain from birth to weaning failed to remove the dependence of adjusted weight on age. Sex was the most important source of variation and the mean difference between male and female calves was 12·9 kg. Sex difference was markedly influenced by herd production rate, being greater in herds of above average production.Weights of calves of 3-, 4- and > 11-year-old dams deviated from those of dams aged 5–10 years (mature) by 14·5, 8·5 and 2·9 kg, respectively. Herd mean influenced the difference between 3-year-old and mature dams, the difference increasing as herd mean declined. Herd-year specific factors seem more appropriate for sex and 3-year-old dams and an annual crop of > 50 calves would confer an advantage to herd-specific over general adjustment factors. On the basis of equality of variances within subclasses, multiplicative factors were superior to additive factors for sex of calf and month of birth; both types of adjustment were suitable for age of dam.

Abstract:
SUMMARYTwenty-four Bos indicus cows of the Mashona/Nkone breeds, 36 dairy crossbreds (Mashona/ Nkone x Friesian), 48 Holsteins, 42 Friesians and 25 Jerseys were used to study the effect on milk production of sometribove (500 mg), a prolonged release formulation of bovine somatotropin (BST). BST was administered at 14-day intervals by subcutaneous injections into the ischio-rectal fossa which lies lateral to and on either side of the anus (tailhead). With the exception of the Bos indicus cows, which received seven injections of BST, all other treated cows received eight.The administration of BST to Bos indicus cows, significantly (P < 0·05) increased milk yield from 0·45 to 1·75 kg/cow per day, and extended lactation. These effects combined to increase total milk production during the 14-week trial from 226 kg for the control group to 993 kg for the group treated with BST. With dairy crossbreds the use of BST significantly (P < 0·01) increased milk yield from 8·6 to 11·0 kg/cow per day. Milk composition for Bos indicus and dairy crossbreds wasunaffected by the administration of BSTBST significantly (P < 0·05) increased milk yield in Jersey (+ 2·9 kg/day), Friesian (+ 3·6 kg/day) and Holstein (+ 2·7 kg/day) cows. Bodycondition of treated cows tended to be slightly lower than that of the control cows at the end of treatment.Cows remained in excellent health throughout all the trials. Farmers commented on how easy the injection was to give in the tailhead site, and on the complete absence of any adverse injection site reaction.

Abstract:
Eulepida mashona Arrow (Coleoptera: Scarabaeidae) is widely consumed in rural and farming communities ofZimbabwe. Preparation methods before consumption for these insects are variable and have not been documented. Our study hypothesised that cooking for different durations result in different nutritional and bioactive compoundscomposition in insects and significant losses of beneficial bioactive compounds. Representative samples derivedfrom standard insect sampling procedures were collected from natural occurrences in Mashonaland West Province, Zimbabwe. Proximate composition and bioactive component analyses were conducted following standard proceduresusing dried pulverised material from whole insects. There were no significant differences in proximate componentsbetween dried uncooked and cooked insects. Both insect samples prepared differently showed high crude protein and fibre contents of 62.4 and 25.4%, respectively, on dry matter basis; values which were higher than those of mostsimilarly handled edible insects in southern Africa. In dried uncooked insects flavonoids occurred in quantitiesof 0.024 mg/g. Relative to other compounds tested, saponins and oxalates occurred in higher quantities, that is, 196 and 28 mg/g, respectively, on dry matter basis. These two components were reduced by factors of 12 and 1.4, respectively, when insects were cooked for 30 minutes and dried. Cyanogen glycosides content was reduced three fold (from 1.4 to 0.43 μg/g) when insects were cooked for 30 minutes. However, safety concerns of hydrogen cyanideexposure exist, also in cases where smaller quantities (<50 g dry weight) of insects are consumed. Studies are neededon adequate processing to reduce risk of toxicity from cyanogen compounds. In general, cooking insects for 30minutes resulted in significant reduction of potentially harmful bioactive compounds namely: alkaloids, cyanogen glycosides, oxalates, tannins and saponins. There is high potential for exploitation of E. mashona as an additional commercial source of protein and fibre if consumer safety concerns are addressed.

Abstract:
Genetic parameters were estimated using 8086 weaning weight records of Mashona cattle from commercial herds in Zimbabwe, through Derivative-free Restricted Maximum Likelihood (DFREML) procedure fitting an individual animal model. All known additive relationships among animals were incorporated and all sires were assumed to have been bred by unknown parents. A simulation study was carried out to estimate the amount of bias in the estimated genetic parameters caused by the failure to account for the true relationships among the breeding animals.
Genetic differences between the weaning weights of Mashona cattle in commercial herds and in small holder herds were estimated using performance records of progeny from 2 reference bulls, 3 bulls from commercial herds, 14 bulls from Makoholi Research Station and 20 bulls from small holder farms. The findings from this study were used as a basis for simulating different strategies of improving the weaning weights of Mashona cattle through the creation of nucleus herds. Estimates ($ pm$s.e) of direct heritability (h$ sb{ rm A} sp2$), maternal heritability (h$ sb{ rm M} sp2$) and the correlation between direct and maternal genetic effects (r$ sb{ rm AM}$) were 0.243 $ pm$ 0.046, 0.392 $ pm$ 0.031 and $-$0.282 $ pm$ 0.081, respectively. When a permanent environmental effect of the dam (c$ sp2$) was fitted, the estimates of h$ sb{ rm A} sp2$, h$ sb{ rm M} sp2$, r$ sb{ rm AM}$ and c$ sp2$ were 0.281 $ pm$ 0.026, 0.113 $ pm$ 0.022, $-$0.269 $ pm$ 0.106 and 0.228 $ pm$ 0.023, respectively. No significant trends were observed in direct breeding values but there was a decline in maternal breeding values. The simulation study indicated that the bias in h$ sb{ rm A} sp2$ and h$ sb{ rm M} sp2$ resulting from the lack of sire pedigrees was trivial if the correlation between direct and maternal genetic effects was high and a large proportion of dams had known pedigrees.
The progeny test showed that both the mean breeding values of the reference sires and the bulls from commercial farms were significantly higher than the mean breeding values of small holder bulls for birth weight (by 1.6 and 1.7 kg, respectively) and weaning weight (by 10.4 and 11.0 kg, respectively). The strategies that selected breeding animals on their maternal genetic values resulted in the highest responses for weaning weight.
It was concluded that maternal genetic values of Mashona cattle should be improved to allow this breed to compete favourably as a maternal breed in commercial agriculture.

Abstract:
This thesis investigates performance parameters of unit operations in the brewery. It describes effects of the parameters temperature and agitation during mashing on mash properties. Mainly two properties are influenced by these parameters, the viscosity and the particle size distribution in the fines. It could be shown that both factors have significant influence on filterability of mash. In pilot scale and laboratory trials particle size effects in mash were investigated systematically. The importance of fine particles for lautering performance could be confirmed and quantified. The precipitation and aggregation of fine particles with increasing temperatures in the mash could be monitored for the first time. It could be shown that this parameter is not malt dependent. Mashes from different malts react in the same way. In laboratory trials it could be proved that the particle size parameter is more important than viscosity for filterability of mash. The parameters described above have been quantified and correlated with mash filtration parameters. This work provided a basis for the development of a computer model which describes mash separation in a lauter tun.

A região dos Andes é conhecida por sua grande diversidade genética em vegetais, sobretudo raízes e tubérculos, que apresentam elevado teor de nutrientes. A população rural da região utiliza os tubérculos como alimentos principais do consumo diário, sendo alguns deles a oca (Oxalis tuberosa Molina), o olluco (Ullucos tuberosus Caldas) e a mashua (Tropaeolum tuberosum Ruiz e Pavón), os quais apresentam cores e sabores particulares. Neste trabalho tais alimentos e suas respectivas frações amiláceas foram avaliados quanto à composição. O amido foi caracterizado quanto às propriedades físicas, físico-químicas e funcionais. As amostras obtidas em mercado local de Arequipa - Perú apresentaram diferenças significativas no rendimento de extração do amido. Quando observados por microscopia eletrônica de varredura e microscopia óptica, os grânulos de amido de oca apresentaram morfologia principalmente elipsoide e oval e comprimentos de até 54,30 µm. Grânulos de amido de olluco com comprimentos de até 32,09 µm apresentaram formatos elipsoide, oval, cônico, em forma de pêra e prismático. Os grânulos de amido de mashua com formas esféricas e ovais truncadas apresentaram os menores comprimentos, até 16,29 µm. O conteúdo de fósforo variou: 0,044% (oca), 0,047% (olluco) e 0,081% (mashua). A porcentagem de amilose foi de 27,60 % (oca), 26,49 % (olluco) e 27,44 % (mashua). O amido de olluco apresentou menor poder de intumescimento, formando géis mais opacos e menos duros. Os três amidos mostraram a mesma estabilidade quando mantidos sob refrigeração e apresentaram elevada sinérese sob temperaturas de congelamento, com variação de 40,28% até 74,42 % para amido de olluco. Os amidos apresentaram fácil cozimento, com elevados picos de viscosidade. Estas baixas temperaturas de gelatinização e a elevada estabilidade durante a refrigeração fazem destes amidos matérias-primas apropriadas para uso em diversos produtos e formulações que requeiram temperaturas brandas de processamento e que prescindam de congelamento.
The Andean region is known for its great genetic diversity in plants, especially roots and tubers, which have a high nutrient content. The rural population on the region consumes them as staple food daily. Oca (Oxalis tuberosa Molina), olluco (Ullucos tuberosus Caldas) and mashua (Tropaeolum tuberosum Ruiz & Pavón) are the most consumed which are characterized by distinct colors and flavors. In the present work, these foods and their starchy fractions were evaluated in relation to its composition. Starch physical, physical-chemical and functional properties were characterized. Samples obtained from a local market in Arequipa - Peru showed significant differences in starch extraction yield. When observed by scanning electron microscopy and optical microscopy, oca starch granules showed morphology mainly ellipsoidal and oval, with sizes up to 54.30 µm. The olluco starch granules had sizes up to 32.09 µm with ellipsoid, oval, conical, pear-shaped and prismatic shapes. Mashua starch granules with spherical and oval truncated shapes showed smaller dimensions up to 16.29 µm. The phosphorus content varied: 0,044% (oca), 0,047% (olluco) and 0,081% (mashua). The percentage of amylose was 27.60 % (oca), 26.49 % (olluco) and 27.44 % (mashua). Olluco starch showed lower swelling power forming gels more opaque and less hardness. The three starches exhibited the same stability when kept under refrigeration and showed higher syneresis under freezing temperatures, with a variation of 40,28 % to 74.42 % for olluco starch. The results showed easy cooking starches with high peak viscosity. These low temperatures of gelatinization and high stability during the refrigeration make these starches suitable for use in various products and formulations that require milder processing temperatures but without freezing.

Abstract:
Lönsamheten för konsultbolag är beroende av antalet timmar konsulter arbetar vad gäller leveranser i kunduppdrag. Att timmar ej levereras på grund av sjukdom eller överbeläggning påverkar resultatet för bolaget. Konsultbolag där konsulter samma vecka arbetar mot olika kunder och uppdrag, kan ha svårt att synliggöra och följa upp leveranserna vilket kan resultera i inkomstbortfall och försenade leveranser. Hypotesen för detta examensarbete är att visualisering och uppföljning minskar risken till inkomstbortfall och försenade leveranser. Författarna har tillsammans med företaget aRway AB testat denna hypotes genom att utveckla ett verktyg för att visualisera prognos och utfall för konsulter på företaget. Rapporten beskriver processen för framtagandet av en lösning för leveransplanering, prognostisering och uppföljning för ett mindre konsultbolag. Rapporten innehåller även en teoretisk bakgrund till arbetet. Resultatet av detta arbete är en lösning som används för att visualisera och följa upp företagets leveranser, vilket har gett en ökad leveransprestation och minskat inkomstbortfall.
Profitability for a consultant company is dependent of the actual consultant hours delivered by consultants in customer projects. The company result will be affected if the consultant hours couldn’t be delivered because of illness or over-allocation. In consultant company’s where consultants work with different projects and customers it can be hard to visualize and follow-up the actual forecast. This could affect the company’s result and also delay the service delivery in projects. The hypothesis for this thesis is that visualization and follow-up of the actual result will reduce the risk for loss of income and delayed projects. The authors in corporation with aRway AB have tested this hypothesis by developing a tool that visualizes the forecast and performance for consultants working at aRway AB. This work have resulted in a report that describes the process for developing a solution that will help smaller consultant companies with delivery planning, forecasting and performance follow up. In the report is also a theoretical background included. Outcome of this work is a tool for visualizing and follow up the company’s deliveries which has given the company an enhanced service delivery and increased result.

Abstract:
The wort from the malted barley used in the Scotch Malt Whisky process must be obtained solely from the activity of enzymes associated with the malted barley. Little or no detailed studies have been reported on the complex mixtures of enzymes found in malted barley, nor their subsequent activity and fate within the Scotch Malt Whisky process. The aims of this study were to determine assay procedures for a total of 17 enzymes, ascertain their suitability within the heterogeneous mixture of a malted barley extract and then establish the enzyme activity levels within the production process. Method development of the assay procedures gave rise to specific assays for 13 enzymes. Especially important were those for a-amylase, using the Phadebas substrate, and the I!-nitrophenyl-maltopentaose substrate for β-amylase. Both assays were found to be specific within the complex mixture of malted barley wort, with all other carbohydrase enzymes active. Enzyme activities between malted barley varieties were studied and compared. This suggested that differences occurred between the enzyme levels of varieties, as well as within a single variety. These may be due to malting conditions or to geographical, environmental and/or climatic factors associated with barley cultivation. The activities and fate of the enzymes were followed during the production process. Although the distillery where the study was carried out employed an infusion mashing system, the results obtained may also be valid in the semi-Iauter/lauter type systems used within the industry. Malted barley enzymes were active during the initial stages of fermentation, but thereafter other enzyme systems were evident. These were most likely associated with yeast and bacteria.

A morphological study of starch from each tubercle, using Carl Zeiss microscope was made. An elliptic starch granules shape for oca, triangular for olluco and globular for mashua were found, and an average size of 30 microns for oca, 15 microns for olluco and 10 microns for mashua were found also. Regarding to ionic character, a similar cationic behavior were shown for all of them. Solubility test for starch granules was made to 60 ºC. Values of 6.97% for oca, 2.75% for olluco and 2.27% for mashua were found, a swellness power of 11.85% for oca, 8.36% for olluco and 4.51% for mashua were found. A viscosimetric study, using Brookfield viscosimeter to 60 ºC was made. Values of 504 for oca, 392 for olluco and 340 centipoise for mashua was obteined. Technological use study was made. As a result only oca starch gave excellent result. An instant food product (crumbs), with good organoleptic characteristics, high acceptability grade and caloric content of 411,5 Kcal for 100 grams of product was obtained. Key Words: Tubercles anden, oca, mashua , olluco , starch , chacarteristation.
