ABSTRACT

       The use of milk replacers to substitute valuable whole milk for suckler goat kids is not widely practiced in the Sudan. The aim of this study was to investigate the effect of two levels of a home-made milk replacer on pre-weaning kid performance, milk consumption, live weight gain, mortality rate and weaning age. Twenty four Nubian male kids of 3 days average age and 3 kg mean live weight were randomly allocated to three treatments each containing 8 kids. Two treatments were offered home- made milk replacer prepared from tallow, egg, groundnut cakes, glucose, minerals and vitamins. Treatment (A) reared on 50% milk replacer and 50% goat milk, while Treatment (B ) on 75% milk replacer and 25% goat milk.  Treatment(C) was offered whole goat milk and used as a control. All kids were offered goat milk for 3 days as adaptation period. Then, each treatment was offered the allocated experimental milk twice daily through plastic bottle feeders of 500 ml capacity at 8 am and 4 pm. The consumption of milk was measured daily for seven weeks. Body weight and mortality rate were recorded weekly. Samples of milk replacer and goat milk were analyzed for total solid, protein, fat, sugar, ash and acidity. The results revealed that, total solids, protein, fat and acidity were significantly (P<0.05) higher in treatment (C) than (A) and (B), however, ash was significantly (P<0.05) higher in treatments (A) and (B) than (C).In addition sugar was not significantly different among treatments. Mortality rate was highest in treatment (B) with 100% increase when compared to (A) and (C) 37.5%.  Milk consumption, feed conversion efficiency, weight gain, and weaning age were not significantly different among  treatments (A) and (C).The study concluded that goat milk could be replaced by50% home-made milk replacer without any deleterious effects on performance of Nubian kids.

  • Respondents Evolution of the Effect of Grazing on Bt-cotton Crop Residues by Ruminants on Health and Milk Characteristics in Gezira State, Sudan

M. A. HASHIM, G. H. ELOBIED AND I. A. ADAWI

Abstract – The introduction of Bt cotton in Sudan enhanced cotton productivity and restored cotton as a main cash crop. Due to fear among animal owners from grazing on Bt-cotton crop residues an investigation in the form of questionnaire was conducted in two sites (South Gezira locality and Um-Algura locality) to know the effect of grazing on Bt-cotton crop residues (Bt-CCR) on animal health and milk characteristic. 50 questionnaires to investigate the effect of grazing on Bt-CCR on animal health and milk characteristic were distributed to each of the two localities. There was an agreement between the respondents in both sites on that, Bt-CCR had some effects on: Milk production, the color of milk, the taste of milk, the impact on animal health and the milk coagulation. There were some symptoms due to feeding on Bt CCR (if it is cultivated) which included: Diarrhea alone, Diarrhea with mucus, Diarrhea and nasal discharge and Diarrhea and bloat. The most animals affected were cows and sheep. It is recommended that, more investigations are needed to elucidate the reasons of those effects, before taking a decision to prohibit the grazing on Bt- CCR. Also investigation of any health effect from milk and its products on human is urgently needed.
Keywords – Bt-cotton residues, Grazing, Animal health, Milk characteristics, GM-cotton.

  • Yield and Chemical Composition and in Vitro Digestibility of Dry Matter of Tabar Plant (Ipomaea kordofana Choisy; Convolvulaceae) in Gezira State, Sudan

M.A. HASHIM, G.H. ELOBIED AND I.A. ADAWI

Abstract – This experiment was conducted in Greater Wad Medani and South Gezira localities in Gezira state, Sudan. The objective of the experiment was to investigate - and estimate the percent botanical composition of Tabar plant (ton/ha) in pasture in Gezira state and to evaluate the chemical composition of Tabar plant using the proximate analysis techniques for crude protein, crude fiber, dry matter and ash content. Also the in vitro digestibility of the plant was determined through a standardized in vitro technique. Before stating the field experiment, 50 questionnaires to investigate the effect of grazing on Tabar on animal health and milk characteristic were distributed to each of the two localities. Tabar the yield was estimated randomly by selecting different number of square meters by throwing the rope (14 times) each week and making the square meter by the rope itself. Chemical composition of Tabar and components were obtained. Proximate analysis of Tabar plant using the procedures of [11]. The statistical design used, was complete randomized design (CRD). The results revealed significant differences in opinion of respondent on Tabar as toddies, yield (ton/ha) from Tabar plant. While the chemical composition and in vitro digestibility was not significantly different in the two localities. It could be concluded that grazing on Tabar was Convincing in DM yield (ton/ha), chemical composition and in vitro digestibility

  • THE SAFETY OF USING IRRADIATED SORGHUM (SORGHUM BICOLOR), USING ALBINO RATS FED ON THEM

Sorghum, the world’s fourth major cereal in terms of production, is a staple food crop of
millions of poor in semi-arid tropics of the world. The objective of this study was to
investigate the safety of using X- ray, Gamma ray and UV light treated sorghum (Sorghum
bicolor (L.) Moench), by testing the renal and liver function parameters of Albino rats fed
on the second generation yielded seeds. Original sample of sorghum seeds was brought
from the local market, cleaned manually, divided into six groups and put in clean Petri
dishes. Four groups were treated with low and high doses of X-ray and gamma ray, one
group was treated with the UV light, while the last was the control. Fifteen Wister Albino
rats were weighed and distributed randomly in six groups according to their irradiated
sorghum feed. After 60 days, blood samples of the Albino rats were collected from the
retrorbital sinus. The blood serum was separated using centrifuge. Renal function and liver
function parameters were determined. The results showed that, the mutant sorghum seeds
were safer to be used (no significant differences in renal and liver functions on the
experimental Rats). Similar studies on other crops should be run.

  • Effect of Feeding Tabar Plant (Ipomaea Kordofana) on Milk Production and Composition in Lactating Dairy Cows, Gezira State, Sudan

M.A. HASHIM, I. A. ADAWI AND G. H. ELOBIED

Abstract – This experiment was conducted in Greater Wad Medani and South Gezira localities in Gezira state, Sudan. The objective of the experiment was to investigate - and estimate the milk production and milk chemical composition and physiochemical properties (acidity and milk pH) of Tabar plant using the proximate analysis techniques for milk characteristics. Before stating the field experiment, 50 questionnaires to investigate the effect of grazing on Tabar on milk characteristic were distributed to each of the two localities. Two herds; one grazed on Tabar in South Gezira Locality and the other grazed on non Tabar in Greater Wad Medani Locality. Milk was analyzed for milk characteristics were determined. The results revealed not significant differences in chemical composition of ash, acidity and pH in milk. While the results revealed significant differences in chemical composition of protein, casein, lactose and fat in milk. The total solid, protein, casein and lactose were higher in milk produced from Tabar grazing. However, water and fat were lower than non Tabar. While the milk production in Tabar groups was highly significantly different (P<0.001).
Keywords – Tabar Plant; Milk Production; Milk Composition.
