Three types of browse fruits (Dign elbasha"Aldizia lebeka Haraz "Faidherbiaalbida "and  Mesquite "Prospis glandulosa " were analysed to determine their chemical composition (DM,EE, CF, CP ,NFE and ME) and digestibility  (DM and CP) . The results showed  significant (P<0.05) differences in their chemical composition. Rumen fluid from three Nubian goats was used as inoculums for in vitro studies for 24 hrs to estimate the ME from gas production.The three samples of feed ,stuff were not significantly different in their energy values.. For estimating the degradability, three fistulated Nubian goats were used. The feed samples were incubated for 3,6,12,18,24,36,48 and 60 hrs in the rumen The experimental models D-a+b(1-e) and Pe =a+be(c+K) were fitted to the data  . It was shown that Mesquite fruits had the highest DM and CP degradability (65 and 59.9g/100gDM respectively) While dign elbasha fruits had the lowest values (48.48 and 51.9g?100g DM respectivity) ,     ,   "

Abstract

     This experiment was conducted in two localities in Gezira state, Sudan. The objective of the experiment was to investigate; the effect of grazing cattle on genetically modified cotton crop residues (designated as Bt-CCR) on milk and cheese chemical composition and sensory characteristics. The results revealed that, there was significant differences (P<0.01) between milk produced from grazing on Bt and on non- Bt CCR. With exception of fat, all other milk components were significantly (P<0.01) higher in milk produced from grazing on Bt CCR. Also the same trend was found in cheese produced from Bt milk. In sensory evaluation of milk, consistency, flavor, taste and overall assessment were significantly better in non Bt milk. While there was no significant difference in sensory characteristics between the cheese produced from Bt and non-Bt milk. It was concluded that, grazing on Bt CCR significantly affect milk and cheese chemical composition but only sensory characteristics in milk. However, more investigation to elucidate these reasons is needed.

  • YIELD AND INTAKE OF BT-COTTON CROP RESIDUES COMPARED TO NON BT-COTTON CROP RESIDUES IN GEZIRA STATE OF SUDAN

M A Hashim*, G H El Obied and I Adawi A
University of Gezira, Wad Medani – 21111, Sudan
ABSTRACT
The study was conducted to investigate and estimate the yield of cotton crop residues (CCR) and to quantify the
botanical composition of Bt and non Bt- cotton crop residues as also to obtain the intakes from the potentially
available dry matter (PADM) from both types of CCR. The experiment was conducted in two localities (South
Gezira and Um-Algura) in Gezira state, Sudan. While one animal herd was grazed on Bt-CCR in South Gezira
locality, the other herd was grazed on non Bt-CCR in Um-Algura locality. The herds were selected as per the animal
owner cooperation. CCR 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. Week zero represents the period
before introduction of animal herd to graze on Bt-CCR. From each square meter, cotton residues were cut at 10 cm
above the earth level .The components of the crop residues were separated into leaves, bolls and tender branches
and then weighed freshly and again after drying in an oven at 105ºC for 24 hours. The results revealed significant
differences in PADM for intake, daily dry matter (DM) intake, crude protein in PADM, daily protein intake, and
percent parts in the intake. Also, CCR from Bt-cotton was higher in total leaves and tender branches. Grazing of
Bt-CCR may be recommended whenever its safety is proved.

  • Effect of addition of effective microorganisms on chemical and rumen fermentation characteristics of wheat straw treated with four levels of urea

Effect of addition of effective microorganisms on chemical and rumen fermentation characteristics of wheat straw treated with four levels of urea

Abstract

 

An experiment was conducted in the laboratories of chemistry and biology, University of Gezira, to find the effects of effective microorganisms (EM) on chemical and in vitro rumen fermentation characteristics of ammoniated wheat straw on April 2011. Wheat straw was treated with four levels of urea (0, 2, 4 and 6%). Two sets of three replicates each were used. To one set EM was added, while the other one which included no EM was used as a control. It was found that addition of EM increased the urea nitrogen fixed in the straw. CP (crude protein) increased while CF (crude fiber) decreased with increasing levels of urea. The corresponding levels with added EM showed more increase in CP and a decrease in CF, though it was not significant (P>0.05). However, at higher urea levels, the straw was significantly (P<0.05) improved in terms of increased CP and decreased CF. The DM (dry matter), OM (organic matter), CP and CF digestibilities were improved with increasing levels of urea and it was substantially increased with addition of EM. Rumen fluid pH tended to increase with the increasing levels of urea in both the control and the treatment. Rumen NH3-N increased significantly (P<0.05) at 4% and 6% levels in treatments which included  EM and at 6% level in ammoniated straw without EM. Also, there was a trend of increasing total protozoal count with inclusion of EM but this was not significant (P>0.05). It could be concluded that inclusion of EM to ammoniated wheat straw improved both the chemical and the in vitro rumen fermentation of wheat straw and reduced urea–N lost to the atmosphere.

  • Blood growth hormone level as an indicator to some lactation characteristics in Butana cows

Mohamed A. Bakheet, Mohammed E. Mohammed, Greeballa H. Elobied

Abstract

 

 

This study was conducted at Atbara Animal Breeding Research Station in December 2006. The objectives of the study were to determine the blood growth hormone (GH) level in Butana cows and to investigate its relationship with some lactation characteristics and to develop a model to predict milk yield and lactation length in Butana cattle using the blood growth hormone level. Blood samples were collected from 12 cows in different lactation seasons. For each cow, milk yield as well as lactation length were recorded. Plasma GH level was determined using radioimmunoassay (RIA) technique. The results showed that, the mean blood GH level in Butana cows was 12.36 (mm/l). Also, it showed that blood GH level was positively correlated with daily milk yield (P < 0.01) and lactation length (P < 0.05). The coefficients of determination for the milk yield and lactation length using blood GH level were 0.61 and 0.41, respectively. Based on the previous findings, it could be recommended that, in addition to blood GH Level, other factors may be included in future models for prediction of milk yield and lactation length using large numbers of cows. GH level alone is a poor predictor for milk yield and lactation length.
