Abstract
The study was aimed to determine the effect of granting Soybean meal protection against nitrogen balance of thin tailed sheep (male). The experimental animals were 16 thin tailed sheeps (males) aged 8 months old with average body weight of 11.81 ± 1.65 kg. The research was assigned in completely randomized design (CRD) 4 treatments and 4 replicates T0 (complete feed + soybean meal without tannins), T1 (complete feed + protected soybean meal 0.5% tannins), T2 (complete feed + protected soybean meal 1% tannin), and T3 (complete feed + protected soybean meal 1.5% tannins). The parameters observed dry matter intake (DMI), DMI /% BB, DMI / BB0.75, nitrogen intake (NI), N-Faecal, N-Urine, N-Digested and N-Retention. Data were variance analyzed by F test (P<0.05), followed by Duncan's Multiple Range Test. The results showed that DMI, DMI /% BB, DMI / BB0.75, nitrogen intake (NI), N-Faecal and N-Digested no effect (P>0,05) of treatment. N-Retention Lowest in T2 (9,87 g/day) while T0 (11,76 g/day), T1 (11,71 g/day), T3(11,86 g/day) no significant (P>0,05), inversely with N-Urine decreased in T2 (3,09 g/day) dan T0 (2,04g/day), T1 (2,23 g/day) dan T3 (1,95 g/day) no significant (P>0,05) as a result of treatment. Based on the results of this study concluded that the use of various mangrove leaf tannin levels up to 1.5% to protect soybean meal no effect on consumption, N-Faecal, and N-digested but protection cake with tannin 1% decrease N-retention and increase the excretion of N-Urine.
Highlights
Adequacy of feed for livestock is very important because it is needed to meet the basic necessities of life, growth, production and reproduction
CJAH/Vol.1/No.1/23-27/December 2016 quality is influenced by the availability of feed protein that is able to contribute to the proliferation of microbes in the rumen and capable of supplying the feed protein in the intestine (Cahyani et al, 2012).Fulfilling the needs of protein in ruminant feed should be calculated the amount of protein that can be degraded in the rumen and the amount of protein is not degradation in the rumen
Measurement of nitrogen balance Thin Tailed sheep to determine the effect of tannin protected soybean meal with different levels of administration
Summary
Adequacy of feed for livestock is very important because it is needed to meet the basic necessities of life, growth, production and reproduction. Protein soybean meal needs to be protected from rumen microbial degradation. Measurement of nitrogen balance Thin Tailed sheep to determine the effect of tannin protected soybean meal with different levels of administration. This study aimed to determine the effect of soybean meal to the balance of tannins protected nitrogen thin tail sheep ram. 2. Methode The ration consisted of complete feed supplemented with soybean meal as a protected mangrove leaf tannin treatment. Tannins obtained from the mangrove leaves mangrove leaf extract using soxhlet method with 96% alcohol solvent (Marnoto et al, 2012). Soybean meal is protected with the way the crystals are dissolved in water tannins. Complete feed formulated using elephant grass, rice bran, soybean meal protected, cassava peel and minerals.
