  • Phenotypic Body Measurements as Predictors of Body Weight in Butana Cattle Ecotype under Field Conditions in Sudan

Data on body weight (Bwt) and phenotypic body measurements; heart girth (HG), Body length (BL) and height at withers (HTWs) were individually collected from mature (N = 200, males (n) = 50 and females (n) = 150) Butana cattle ecotype that thrive under field conditions in Butana area of Sudan between October and March 2013. The aims of the Study were to: (1) determinate certain phenotypic body measurements, (2) evaluate the effect of sex on the body weight and phenotypic body measurements, (3) establish associations between body weight and phenotypic body measurements and (4) predict body weight from phenotypic body measurements in Butana cattle ecotype by Statistical analysis models. Data collected were subjected to least squares analysis using general linear model procedures when phenotypic body measurements (cm) and animal body weight (kg) were outcome variables and animal sex as input variable, simple linear Pearson's correlation and regression analysis were performed. Findings indicated that males showed higher values for body weight and phenotypic body measurements (P˂ 0.05) than females, the correlation coefficients (r) between body weights and heart girth measurements ( r = 0.90 for males and 0.98 for females) were strong, positive in direction and significant (P˂ 0.001). Simple linear regression models were fitted (P˂ 0.05) with body weight as dependent variable and heart girth as independent variable. Body weight had a linear relationship with heart girth (R2 = 0.81 and 0.96) for males and females respectively. The coefficient of determination indicated that heart girth measurement succeed to describes more variation in body weight. Thus, heart girth taken with a tape is the phenotypic body measurement that is most appropriate for prediction of body weight more accurately in Butana cattle ecotype under field conditions in Sudan. Results obtained in present study would also be valuable, useful and helpful to animal breeder and farmers in field conditions who are involved in cattle study.

Keywords: Phenotypic measurements, correlations, prediction, Butana cattle, Sudan.

  • Effect of Dietary Inclusion of Tamarind (Tamarindus indica L.) seeds on Broiler Performance and Carcass Characteristics

The objective of the study was to measure the effect of dietary inclusion of different levels of raw and processed tamarind seeds on broiler performance and carcass characteristics. The processing implemented for seeds in this trial was boiling. The tamarind seeds were divided into two categories (raw and treated with boiling) and then ground to be included in experimental diets. A total of 180 unsexed one-day broiler chicks (Ross 308) were distributed to 15 pens that were randomly assigned to five treatments. Each treatment was replicated three times (12 birds per pen).  In a completely randomized design, the dietary treatments consisted of 5 and 10% raw (TRS), 5 and 10% processed (TBS) and 0% tamarind seeds (control). The experimental diets were formulated iso-nitrogenous and iso-energetic to meet or exceed the requirements of finisher period for broilers (NRC, 1994). At day 42, two birds per replicate were slaughtered to measure the carcass and organs weights. The results showed that tamarind seeds contained 15.98% protein, 3.77% fat, 43.5% ash, 11.4% fibre, 2.41% tannin (dry matter) and 13.06 MJ/kg metabolizable energy. Boiling treatment decreased tannin content by 31%. All birds fed with diets contained tamarind seeds were better in weight gain and feed conversion ratio than those fed control diets (p≤0.01).The highest feed consumed were reported with birds fed on control diets. There were no significant differences (p≥0.05) between different treatments in gizzard, abdominal fat, drumstick and last body weights. The greatest carcass weight was observed with control treatment followed by TBS 5% treatment (p≤0.01). The heaviest and the lightest weights of breast were recorded with control and TRS% treatments, respectively. Birds fed on TBS and control treatments had the biggest thigh weights (p≤0.01). The current study indicated that TRS and TBS scored the best results for broiler growth performance. However, TBS treatments could be the second choice following the control for weights of most edible parts of the carcass. So, tamarind seeds could be used as alternative feedstuff for poultry as protein and energy source specially when treated with boiling.

  • Correlating Mean Annual Rainfall over Sudan and South Sudan to Latitudes, Longitudes and Altitudes

/

Abstract Analysis of Sudan and South Sudan rainfall normal data for the last seventy years showed that Sudan and South Sudan rainfall decreases with latitude at an average rate of about 67 mm per degree from south to north, that Sudan and South Sudan rainfall increases with elevation at average rates of 1.0 mm and 2.4mm per meter above sea level according to pattern type and after a base elevation and that longitudes showed on average no or mild effects on rainfall, although they showed some clear localized patterns. Equations were formulated to predict Sudan and South Sudan rainfall in areas where no measurements are available, but they should be used with caution.

 

Key Words Correlation, latitude, longitude, rainfall, Sudan.
