Effect of Partially or Totally Replacing Soybean Meal by Guar Korma Meal on Sheep and Cows Performance Milk Production.

Abstract

This study was carried out to determine the effects of using different levels of Guar korma meal (*GK) on milk yield and milk composition, rumen function of experimental rations fed to sheep and dairy cows. Animals were fed one of from experimental rations, control ration with 0% GK or rations with 5%, 10% and 15% GK. Animals fed rations containing guar korma showed linear decrease (P < 0.05) of total dry matter intake (DMI) with increasing ration guar korma meal level inclusion in rations. Twelve Barki male sheep were assigned randomly into 4 similar groups of 3 animals each to determine the digestibility coefficients, nitrogen balance and nutritive values of experimental rations. Results of digestibility trails showed that there were no significant differences (P< 0.05) in digestibility of DM, OM and CP for ration containing 10% GK compared to the control ration. While, there was significant (P < 0.05) decrease rations containing 5%, 15% guar korma. Similar trend recorded for the nutritive values. However, nitrogen utilization showed positive nitrogen balance with all animals fed the experimental rations. Three cannulated female Barki sheep were used to determined rumen fermentation parameters. The main results showed no significant differences among experimental groups in the values of ruminal pH and NH3-N concentrations, while the highest (P < 0.05) of TVFA'S concentrates were observed with the ration containing 10%GK and the control ration than rations containing 5%,15% guar korma. Dry matter and CP degradability showed significant (P < 0.05) increased for rations containing GK than the control ration. Eight lactating crossbred Friesian cows were used to determine milk yield and milk composition. Cows fed ration containing 5% GK showed slight improvement in milk yield in comparison with the control ration. However Milk fat (%) increased (P < 0.05) for rations containing guar meals compared with the control ration. *GK= guar korma meal

Guar Korma: A Good Alternate to Replace Groundnut Cake in the Diet of Buffalo Calves: A Review

“…Nidhina and Muthukumar (2015) reported the chemical composition of guar korma as moisture 8.2%, Ash 5.1%, crude fiber 4.9%, protein 52.7%, NFE 23.6% and ether extract 5.4%. Walaa et al, (2016) founded that guar korma meal contained 50.00% CP, 10.80% CF, 2.86% EE, 4.15% TA and 32.19% NFE whereas, similar values reported by Soliman et al, (2014) were 55.80%, 7.50%, 4.70%, 5.40% and 26.00%; by Saeed et al, (2017) were 56-58%, 3-4%, 4-5%, 1-2% and 21-25% and by Etman et al, (2014) were 50.00%, 6.70%, 6.00%, 5.00% and 32.30%, respectively.…”

“…Total-N and protein-N concentrations showed significantly (P<0.05) higher with animals fed rations E and F, recording increased concentrations with increasing sampling times. Overall average of total-N ranged between 118.82 to 131.29 mg /100 ml versus 89.22 to 94.35 mg /100 ml for protein-N concentration, showing the highest concentration was recorded with animals fed ration F. Soliman et al, (2014) replaced soyabean meal (R 1 ) by guar korma meal in the ration of female sheep at the rate of 33% (R 2 ), 66% (R 3 ) and 100% (R 4 ) level The results of ruminal parameters showed insignificant differences (P<0.05) among experimental animals in the values of ruminal pH and NH 3 -N concentration. However, the animals fed rations containing guar korma recorded slightly higher NH 3 -N concentration compared with the control animals.…”

“…Increasing of DM intake might be due to higher palatable guar korma. Soliman et al, (2014) replaced soyabean meal (R 1 ) by guar korma meal in the ration of lactating cows at the rate of 33% (R 2 ), 66% (R 3 ) and 100% (R 4 ) level. Total dry matter intake (DMI) of rations R 3 and R 4 was less than the rations R 1 and R 2 , these differences were statistically significant at (P< 0.05).…”

“…The only reported OM digestibility is 76% and 71% for the processed and unprocessed meal, respectively (Islam Shah et al, 1964 Grewal et al, (2014) reported that when 10% soybean meal in concentrate mixture of growing male buffalo calves was replaced with roasted guar korma upto 70% the nutrient digestibility for DM, OM, CP, NDF and ADF were 74.21, 77.09, 76.38, 72.72 and 65.23%, respectively and there was no difference in the nutrient digestibility of both the groups. Soliman et al, (2014) replaced soyabean meal (R 1 ) by guar korma meal in the ration of sheep at the rate of 33% (R 2 ), 66% (R 3 ) and 100% (R 4 ) level. Animals fed R 1 and R 3 showed highest (P< 0.05) digestibility values of DM, OM, and CP compared with other rations.…”

Economics of Milk Production Feeding Different Protein Supplements of Gir Cows

“…Guar meal can be used to substitute other protein sources without any side effect reported by Turki et al, 2011. The feed cost proved that ration contained 5 per cent Guar korma improved the economic return (L.E. /H/D) recorded by Soliman et al, (2014). Sharif et al, (2014).…”
