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.

Abstract

This work aimed to use guar korma meal in concentrate feed mixture(CFM) for growing buffalo calves rations.The trial was carried out at Animal House of Animal production Research Institute and Al-Manar Company Station. Thirty male buffalo calves averaging 176.9 Kg LBW were chosen and divided into six similar groups. The groups of animals were randomly assigned to receive six experimental rations containing CFM which included guar Korma at the rate of 0, 3.3, 6.7, 10.0, 13.3 and 16.7% in rations A,B,C,D,E and F, respectively. These percentages of guar korma cover 0,10,20,30,40 and 50% of CFM protein content. All animals received CFM, berseem hay (BH) and wheat straw (WS) at the rate of 70:20:10, respectively.The feeding trial lasted 210 days, during which live body weights were recorded beside feed intake. Economical efficiencies were calculated for each ration. In addition, six digestibility trials were conducted to determine digestibility and nutritive values of the experimental rations. Samples of blood were taken to measure some blood parameters.The results obtained can be summarize as follows: 1) The chemical composition of different experimental rations were almost similar in DM, OM, CF,CP and NFE contents, with somewhat higher percentage of EE and Ash associated with increasing guar korma levels. 2) Increasing guar korma level in the experimental rations tended to significantly (P<0.05) increase DM, OM, CP,EE and CF digestibilities, while the difference in NFE digestibility was not statistically significant. In addition, there were significant (P<0.05) increase in TDN and DCP with increasing guar korma levels in the rations, especially in ration F, which had 70.82% TDN and 10.99% DCP. 3) Average total protein and albumin were significantly (P<0.05) higher for ration D,E, and F, while differences in globulin were not significant. Also, AST (Aspartate amino transferase) and ALT (Alanin amino transferase) concentrations significantly (P<0.05) increase for ration E and F, while differences in kidney functions parameters were not significant. 4) Average daily LBW gains significantly (P<0.05) increased with increasing guar korma levels in the rations, being 1.296,1.325,1.357,1.392,1.425 and 1.475 kg for animals given rations A,B,C,D, E and F, respectively. At the same time, the best improvement in feed utilization efficiency expressed as kg DM or TDN per kg gain was recorded for ration F which contain the highest level of guar korma, being 7.935 and 5.620, respectively. 5) Average feed cost/kg weight gain decreased with increasing guar korma levels in the rations, being 18. 870, 18.227, 17.429, 16.650, 15.822 and 15.249 LE with rations A, B, C, D,E and F, respectively. Moreover, revenue, gross margin above feed cost, profit and economical efficiency showed the highest values for ration F,

Effect of Using Dried Distiller Grains With Soluble (Ddgs) as a New Protein Source on Meat and Milk Production and Their Qualities. 2- Comparative Studies to Use Dried Distiller Grains With Soluble (Ddgs) Instead of Cotton Seed or Soybean Meals as a Source of Protein in Ration of Fattening Friesian Calves.

“…With this respect, the feed utilization efficiency with ration D recorded 8.671, 5.946 and 0.806 kg DM, TDN and DCP per kg gain, respectively, while feed utilization with ration A as kg TDN or DCP per kg gain were the most efficient as shown in Table (4). Generally, the better feed efficiency with animals fed ration D (containing DDGs) was agreement with those reported by Etman et. al., (2014aand 2018) and El-Shinnawy et.…”

Effect of Using Dried Distiller Grains with Soluble (Ddgs) as a New Protein Source on Meat and Milk Production and their Qualities: 1- Using Dried Distiller Grains with Soluble (DDGS) Instead of Cotton Seed Cake or Soybean Meal Cake in Rations of Lactating Friesian Cows

“…They found that the NDF was 46% for DDGS versus 40 and 15% for undecorticated cotton seed cake and soybean meal, respectively. Also, increase in digestibility coefficients of most nutrients for ration D were found with increasing DDGS levels in CFM of ration as a source of protein (Etman et al, 2014a).…”

Analysis of buffaloes fed roasted guar korma with regard to rumen fermentation

“…~ 121 ~ Processed guar korma is rich in carbohydrates and proteins, which makes it a great source of protein for ruminants and other animals. It is mostly fed to milking animals in order to increase the amount of milk and milk fat content, in addition to being a good feed for beef cattle (Etman et al, 2014a) [5] . The CP content of guar korma has been reported to vary from 56 to 58 percent by Saeed et al (2017) [19] , 55.8 percent by Soliman et al (2014) [18] , 52.7 percent by Nidhina and Muthukumar (2015) [15] , 50 percent by Etman et al (2014a) [5] , and 46.9 percent by Grewal et al (2014) [9] .…”

The CP content of guar korma is influenced by the kind of germ fraction and heat treatment applied to the finished product.…”
