Essential – Mineral Balance on Growing Male Cattle

An experiment was designed to study the effect of unconventional protein source on the essential minerals balances of growing cattle.  The experiment had been conducted by experimental method with Completely Randomized Block Design, on twelve growing male cattle of Ongole Grade.  Based on the body weight, the animal trial was separated to three blocks, as the replication.  The tested treatment was four kind of protein sources in the ration (R):  R1 = kapok – seeds cakes; R2 = lamtoro – leave meals; R3 = cacao – pod meals and R4 = goat’s faeces.  The compose of ration was 50 percent of Elephant grass and 50 percent of concentrate (DM basis).  The measured variables were: the essential mineral balances i.e. Calcium, Phosphorus, Sodium, Potasium, Chlorine, Magnesium, Sulphur and Nitrogen.  The balance – trial was conducted by the total collection method.  The data was analyzed by the analysis of variance, and that of the interaction (Synergistic and antagonistic) by the Regression Analysis.  The result indicated that the total of essential mineral balance of each protein source or each ration on growing cattle of Ongole Grade is:  Cacao – pod meals = 116.09 g/day; Goat’s faeces = 111.89 g/day; lamtoro – leave meal = 84.64 g/day and Kapok – seed cake = 78.55 g/day.  These phenomena shown that all of the animal trial was in normal growth.  The strong synergistic interaction was reached by Ca « P (P <0.01; R2 = 0.92 – 0.98) while the weak interaction by Na « Cl (P > 0.05; R2 = 0.03 – 0.05).  Among the five couples of mineral elements of the antagonistic interaction the strong interaction was N ® S (P < 0.01; R2 = 0.70 – 0.75), while the weak interaction was Na ® P (P > 0.05; R2 = 0.08).  Based on all the variables measured, the experiment is concluded that: (1) all of the unconventional protein sources are able to improve the quality of the ration, indicated by the positive essential mineral balance on growing cattle of Ongole grade; (2) based on the total essential mineral balance, the most suitable protein source for growing cattle is cacao – pod meals; (3) the strong synergistic interaction was reached by Ca <----> P, while the antagonistic interaction was N ----> S.  (Animal Production 6(2): 101-109 (2004) Key Words: mineral, protein source, Ongole, cattle

The Effect of Urea and Sulphur Level in Mixing of Cassava Waste Fermented and Soybean Cake waste on Nitrogen Balance and Digestibility of Energy of Local Male Sheep

Cassava waste and soybean cake waste are by - product from home industry  that  have been used as animal feed. It contain high crude fibber, there fore it must be processed or added with another nutrients before feeding to animal to get a good performance. A research have been  conducted in Experimental Farm and Laboratory Animal of  Feed and Nutrition, Animal Science Faculty, Jenderal Soedirman University, Purwokerto at October- Nopember 2001. The purpose of  the research is to find the effect of urea and sulfur  level in mixing of cassava waste fermented and soybean cake waste on nitrogen balance and digestibility of energy of local male sheep. Eighteen local male sheep were  divided into 3 group based of the body weight. There are I = 18.55±1.27 kg, II = 15.79±0.67 kg and  III = 13.41±1.33 kg. Two level of urea (2% and 3%) and three level of sulfur (0 %, 0.15 % and 0.30%) dry matter concentrate used as  treatments, there fore factorial   design 2x3 with Randomized Block Design used this experiment All of treatment received same diet consist land grass and concentrates with 70:30 dry matter ratio. Concentrates consists  cassava waste fermented  and soybean cake waste with 77.50:22.50 dry matter ratio.  Dry matter intake was 4 % body weight. Observed variables were nitrogen balance and digestibility of energy by using total collection. Variance analysis was used for knowing the effect treatment on the variable observed. The result of the research shown that level of urea and sulfur are not significant interaction on the nitrogen balance and digestibility of energy.  However  level urea and sulfur  itself are significant on nitrogen balance linearly. Level urea also had significant effect on the energy digestion.  Balance nitrogen of all treatment is positive. Level of urea 3 % and sulfur 0.30% gave a good balance nitrogen and energy digestion.  It can be concluded that addition of urea and sulfur in diet containing fermentable  carbohydrates can increase balance nitrogen (N retention) and energy digestion.

Performance of growing male quails under different Complete Feeds and Floor Sorts

A research entitled “Performance of Growing Male Quails Under Different Complete Feeds and Floor Sorts” has been conducted in experimental farm, Faculty of Animal Husbandry Unsoed  Purwokerto.  The objective of the study is to find out the best floor sort and complete feed for performance of growing male quails. One hundred and fifty male quails at three weeks old were used in this study. Split Plot Design were used in this research. Floor sorts  were used as  maintreatments and they consists of L1 (litter floor) and L2 (wire floor) Complete feeds were used as subtreatment and they consists of  P1 (AD 51), P2 (CP 511), P3(B 11) and P4 (BR 1). Deck levels were used as deck  andT1 (high), T2 (meden) and T3 (low deck). Statistical analyses showed that complete feeds had significant effect (P<0.05) on feed consumption but not significant on body weight, growth and feed conversion. Floor sorts and their interaction  with the complete feeds  had not significant on the performance of the birds. It can be conclused that during growing period, P1 (AD 51) gave better performance and for floor shorts, either litter or wire can be used to growing male quails.
