Utilization of New Nutritional Resources in Ruminant Feeding: 2) Effect of Using Dried Distillers Grains With Soluble (Ddgs) as Protein Source in Rations for Fattening Buffalo Calves

Abstract

The present work was carried out to study the effect of using dried distillers grains with soluble (DDGS) as a source of protein in ration formulation of buffalo calves. DDGS was included in concentrate feed mixture (CFM) at 0, 11, 16, 21 and 27% to cover 0, 20, 30, 40 and 50% of total protein, respectively. Fifty male buffalo calves averaging 320.16 kg live body weight were randomly distributed into five similar groups (10 in each) and assigned to receive five concentrate feed mixtures containing five levels of DDGS. Animals were fed CFM along with berseem hay and wheat straw at the ratios of 70: 20: 10, respectively. The feeding trail lasted 184 days, during which, five digestibility trials were carried out to determine the digestibility and feeding values of the experimental rations. In addition, samples of rumen liquor and blood serum were taken to determine some ruminal and blood parameters. Also, feed and economical efficiencies were studied. The results showed that: 1-Digestibility coefficients were significantly (P<0.05) higher in DM, OM, CP and CF with animals fed rations containing DDGS. Nutritive values expressed as TDN (%), DCP (%) and DE (Mcal/Kg DM) were significantly higher (P<0.05) for ration E (containing 27% DDGS) than the other rations. 2-Animals fed ration E (containing 27% DDGS) showed the highest TDN (77.03%) DCP (12.49%) and DE (3.40 Mcal/Kg DM) versus 65.67%, 11.00% and 2.89 Mcal/Kg DM for animals fed control ration. However, all experimental rations (containing DDGS) appeared to higher nutritive values than that of control ration. 3-The highest daily gain (1.170 Kg) was recorded with animals given ration E, which had 31.46% extra improvement and increase in weight gain. Also, animals fed experimental rations (B, C, D and E rations) tended to have better feed efficiency, showing the best feed utilization efficiency expressed as DM, TDN or DCP per Kg gain being 11.147, 8.586 and 1.392 Kg/Kg gain, respectively, for animals fed ration E. 4-Animals fed ration E (containing 27% DDGS) appeared to have the lowest feed cost/Kg weight gain (17.837 LE).The highest economical efficiency (1.233) versus the highest feed cost and lowest economical efficiency was observed with animals fed control ration (ration A). 5-All ruminal and blood serum parameters were within the normal values, showing that added DDGS in ration formulation of fattening buffalo calves had no adverse effects on serum parameters and led to get better performance of animals. Generally, it may be concluded that, the inclusion DDGS at 27% to cover 50% of total protein of concentrate feed mixture in fattening buffalo calves rations tended to produce better nutrient digestibility and feeding values. Moreover, animals fed rations containing DDGS had higher weight gains and lower feed cost with the best economical efficiency without any adverse effects on ruminal or blood serum parameters.

Using a New Protein Sources in Feeding of Ruminants 1- Effect of Feeding Different Levels of Guar Korma as a Source of Protein on the Productive Performance of Egyptian Buffaloes.

“…Table (5) showed that the average daily feed unite intakes increased with increasing guar korma percentages in CFM owing due to its high palatability and higher both digestibility and feeding values of guar korma. Such results were agreement with those reported by Etman et al, 2011 and2014;Turki et al, 2011;Shwerab et al, 2010 andSehgal andMakker, 1994. Effect of feeding guar korma on blood parameters:…”

“…Also, there were improvements in economical efficiency with increasing guar korma level in experimental rations, being 3.52, 8.23, 13.29, 19.21 and 23.76% with rations B, C, D, E and F, respectively. From the previous results, it may be shown that the animals fed rations containing the highest level of guar korma (16.7%) which represent 50% as a source of protein of CFM appeared to have the lowest feed cost/kg gain with the highest revenue, profit and economical efficiency. The results were agreement with those reported by Turki et al, (2011), Saleh pour et al(2012),TarunaKhanna et al, (2010 and Etman et al, (2011 and2014) CONCLUSION Guar korma meal could be used as a source of protein to partially or totally replace cotton seed cake and soybean meal in concentrate feed mixture of growing buffalo calves rations. Moreover, guar korma meal could be used at the rate of 50% in CFM instead of both cotton seed cake and soybean meal in ration formulation of buffalo calves.…”

“…In addition, Shwerab et al (2010) showed higher digestibility coefficients and nutritive value with increasing DDGS in sheep rations. The same results were obtained with Etman et al (2011). They found that using DDGS as a source of protein in rations formulation of buffalo calves increased digestibility coefficients of all nutrients and feeding values.…”

“…The obtained values of some blood profiles of tested groups in present study were within the normal range for healthy goats given by Plumb (1999) being 2.4:4.4 g/dl , 64.6:136.4 mg/dl , 0.9:1.8 mg/dl , 66:230 and 15.3:52.3 U/L for albumin , cholesterol , creatinine , AST and ALT concentrations , respectively. However Etman et al (2011) recorded that most of blood parameters were not affected by adding DDGS in experimental rations with fattening buffalo calves. tested rations.…”

“…Similar results reported by Gabr et al (2010a) , Ghoneem and Mahmoud (2016) and Etman et al(2012). In general, liver function might be affected by other factors such as age, body weight or administrative circumstance related to good or bad feeding (Etman et al, 2011).…”
