Effect of Biologically Treated Sugar Beet Pulp on Lactating Goat Performance

Abstract

This study amid to investigate the effect of using sugar beet pulp (SBP) untreated or treated with biological treatments to replace about 30% of common concentrate feed mixture of goat diets. In vitro experiment was carried out to study the effect of control, treated and untreated SBP on nutrients disappearance. Experimental diets included T1: Concentrate feed mixture (CFM) + Berseem hay (BH) (control). T2: CFM + untreated SBP + BH. T3: CFM + SBP treated with Sacharomyces cerevisiae + BH. T4: CFM + SBP treated with Clostridium cellulovorans + BH. T5: CFM + SBP treated with Trichoderma harzianum + BH. Thirty five female Barki goats (about 4 years old and weighing 30±1.5 kg) were randomly divided into five groups fed the experimental diets. The experimental period lasted 270 day to study the effect treatments on goat doe performance during pregnancy and lactation stages and their kids performance until weaning. A digestibility trial was carried out at the third month of pregnancy. The results revealed that biological treatments significantly (P≤0.05) increased body weight and feed intake. Also, biological treatments significantly (P≤0.05) improved chemical composition, digestibility coefficients, nitrogen balance, water balance, rumen fermentations, milk yield and composition, birth and weaning weight. It could be concluded that, inclusion of untreated or biologically treated SBP to replace 30% of common concentrate feed mixture of during pregnancy and lactation stages had remarkable improved influence on goat performance.

Nutritional Value of Sugar Beet Pulp and Olive Cake Treated by Using Monism Biological Treatment and Its Effect on Sheep Feeding

“…Similar results were obtained by Dawson and Tricarico (2002) and Marghany et al (2005) who reported that addition of live yeast culture to ruminant diet has improved fiber digestibility and stimulated cellulolytic bacteria. Also, Aziz (2014 and2015) found an increase in total and cellulolytic bacteria numbers in rumen of goats and sheep fed biologically treated SBP.…”

“…Also, Aboul-Fotouh et al (2013) found that treatment of OC with yeast increased digestibility coefficient and nutritive values. Aziz (2014 and2015) found an increase (P≤0.01) in digestibility coefficients, TDN, DCP and ME for sheep fed biologically treated SBP. Abdou (2017) found that sheep fed biologically treated OC recorded higher values of feed intake and improved all nutrients digestibilities, TDN and DCP than those fed control.…”

“…Aziz (2004 and found that biological treatments for poor quality roughage increased total and differential numbers of ruminal protozoa. Also, Aziz (2014 and2015) indicated an increase in ruminal ciliate protozoa for sheep and goats fed biologically treated SBP.…”

“…Allam et al (2006) reported that biologically treated SBP with T. viride and S. cerevisiae had the highest value of nitrogen balance. Aziz (2014 and2015) found an increase in nitrogen balance of sheep and goats fed biologically treated SBP.…”

“…Also, Kholif et al (2005) showed that values of ruminal TVFA's increased significantly (P<0.05) with dietary treatment of T. viride followed by S. cerevisiae compared with the non-treated control. Aziz (2014 and2015) found that rumen parameters and microbial protein production of sheep and goats were improved with ration contains SBP treated with T. viride and S. cerevisiae. Abdou (2017) found that biological treatments of OC improved ruminal pH and VFA's and NH3 concentrations of sheep.…”
