O.; K, Ahmed. A.; A, Elnazeir. B.; M, Atta. Abstract: The study was conducted to evaluate the effect of feeding guar germ and guar bran as replacement of groundnut cake and wheat bran, respectively in diets of crossbred fattening cattle. Fourteen crossbred Friesian young calves were divided into two groups (A) as control fed on pelleted feed and group (B) fed the experimental diet (guar mix) with an average initial live weight 144.2 15.5 kg. Feed intake and live weight gain were collected on daily and weekly basis, respectively. Slaughter and carcass data were also collected. The control group was superior the experimental group the following parameters: Feeding period (101 days), feed conversion efficiency (5.04 DM/Kg live weight gain), weight gain (1.05 Kg/day) and daily dry matter intake (5.3 Kg). Control bulls have higher cold dressing out percentage on both full and empty body weight basis (59.8% and 57.8%, respectively). The Barrel circumference and pelvic width showed slightly higher values in the control group without any significant difference. For linear body measurements (cm), the head, hide, four feet, lungs, tracheas, spleen, intestine empty and omental fat were heavier in the control group of bulls. For the carcass yield and carcass characteristic of experimental bulls of the two groups were almost the same. However, the slaughter weight, cold carcass weight and empty body weight were found higher for the control group. For the non carcass components, the values fluctuated between the two groups, with no significant differences (p>0.05). Also no significant (p>0.05) differences were observed between the two groups for fat % and connective tissue % but the control group showed higher muscle and connective tissues while treated group showed higher fat and bone content. It concluded that guar germ and bran can effectively replace groundnut cake and wheat bran, respectively, in diets of fattening cattle.

The percentage weight loss of stored seeds was used as the parameter for determination of the efficiency of the storage units. Considerable losses were recorded at Renk, Upper Nile State, South Sudan and surrounding areas (Guwzrum, Gelhak, Geigar and Wadacona). The results show that, improved gugues (Sweiba) were better storage structure than the local gugues, guttias and small brick stores, because there were less insect infestation, decreased weight losses of grains and better seed quality in improved structures. The weight losses were increased gradually, no weight losses were recorded in the first months and the highest losses were recorded in the last months of the year. The mean cumulative percentage weight loss due to insect infestation during (February)in Gadam Alhamam were approximately 5.30%, in an improved gugu,17.27%, in a local gugu,17.81% in Guttia, (Hut) and 21.01%, in brick stores.While in Fetterita; they were 12.41%, 30.84%, 28.65%, and 25.37%, in improved gugu, local gugu, Guttia and brick stores respectively.

Abstract: A field experiment was conducted during the period from November (2010) to early January, (2012), in two consecutive seasons, in the demonstration Farm of the College of Animal Production, Sudan University of Science and Technology, at Kuku, to study the performance of two Sorghum Cultivars (Sorghum bicolor) "Abu 70" and (Sorghum Sudanense) "Garawia" on a saline soil under four irrigation intervals 7-10-14-21 days, on two different land preparation methods (ridged and flat). Irrigation water supply was from domestic water supply net work. The treatments were arranged in a Randomized Complete Block Design (RCBD), with four replications, the data were subjected to statistical analysis using, MSTAT, Computer program. The main parameters measured were fresh and dry matter yields were taken 70 days after sowing. The crop factor (kc) was taken using CROP WAT Program .based on Penman Monteith equation for Khartoum area. The results showed higher dry matter yields for shorter intervals 7, 10 days, with significant differences. The shorter irrigation intervals showed higher yields for the different soil preparation methods, with significant differences. The interaction between the two crops, the interaction between intervals and soil preparation method followed the same pattern. All growth parameters for the two crops and under the two soil preparation methods gave significant differences in favor of the shorter irrigation intervals.

E.; I, Dagash . Y. Abstract: A field experiment was conducted during the period from November (2010) to early January, (2012), during two consecutive seasons, in the demonstration Farm of the College of Animal Production, Sudan University of Science and Technology, at Kuku, to study the effect of Water Use Efficiency under four irrigation intervals 7-10-14-21 days, on two different land preparation methods (ridged and flat) on production of fodder Sorghum Cultivars (Sorghum bicolor) "Abu 70" and (Sorghum sudanense) "Garawia" on a saline soil. Irrigation was from domestic water supply net work. Soil samples and irrigation water samples were analyzed chemically to determine the actual soil and irrigation water salinity degree, the average Ece and Ecw, were 4.4 ds/m, 0.285 ds/m for soil and irrigation water respectively. The treatments were arranged in a Randomized Complete Block Design (RCBD), with four replications, with an area of 4*5 =20 m2, the data were subjected to statistical analysis using, MSTAT, Computer program. Calculation was done to determine the amount of crop water requirements in (m3) per plot, the application of irrigation water was measured by a (2 inch) flow meter.The main parameters were dry and fresh matter yields. The crop factor (kc) was taken using CROP WAT Program .based on Penman Monteith equation for Khartoum area. The growth measured were: the water use efficiency effect on dry matter yields. The highest value for calculated Eto (Penman Monteith) was during the developing and maturity stage. The values ranged between: (6.99, 6.08, 5.29) mm/ day. This trend was similar for the values of crop factors (kc), which ranged between (0.3 to 1.02). The results showed a higher dry matter yields and water use efficiency in favor of the shorter intervals 7, 10 days, with significant differences on different soil preparation methods within two seasons. Abu 70 within the two seasons on different soil preparation methods under different irrigation intervals, scored a higher dry matter yield than Garawia. The results of water use efficiency followed the same pattern. Abu 70 crop under the two soil preparation methods gave significant differences in favor of the shorter irrigation intervals Description: Articel Wed, 06 Dec 2017 00:00:00 GMT https://repository.sustech.edu/handle/123456789/20252 2017-12-06T00:00:00Z
