Possible Utilization of Corn Steep Liquor (CSL) in Rabbits' Diet

Abstract

A b s t r a c t A r t i c l e I n f oAn experiment was conducted on newly weaned rabbits for eight weeks by fattening them on diets supplemented with corn steep liquor (CSL) replaced 0, 10, 20, and 30% of crude protein and energy of barley and soybean meal of the diets. The obtained results refer to increased feed intake (thus, worst the feed conversion and economic efficiency); serum cholesterol, triglycerides, and low density lipoproteins (referring to somewhat negative effect on liver function, where the serum alanine aminotransferase activity was decreased too); as well as hemoglobin concentration and red blood cells count (as good indicators). Otherwise, there were no significant effects on growth performance, water intake, edible parts, digestibility, and muscular composition. So, it could be concluded that dietary inclusion of CSL (up to 30%) for rabbits is possible without adverse effects on performance and health state.

Growth Measurments of Male Goat Kids Nourished on Unconventional Rice Straws Ensiled by Corn Steep Liquor and Conventional Rice Straws Ensiled by Urea

“…Enhance of total protein could relate to available carbohydrate source, impaired N utilization by rumen microbes thus, both N utilization as well as digestibility of CP were better as a result in serum protein (Mudgal et al, 2018). The non-significant affected of T1, T2 and T3 ration on triglycerides and cholesterol were in agreement with those results observed in Zaraibi kids (Behery et al (2015), in lambs (Azizi-Shotorkhoft et al, 2016) and in rabbit (Abdelhamid et al, 2017) nourished CSL in rations. Noticeably, urea and creatinine concentrations are an indicator to regular filtration in the kidney and also there were not a catabolism situation consequently, being in a good nutritional condition.…”

“…The diagrams have drawn that the positive improvement in body weight of kids were fed T2 compared to T1 and T3 kids throughout extended trial times up to 150 days post-weaning. Hence, modification of feed intake by CSL in T2 ration observed in dairy Zaraibi goats (Khalifa et al, 2013), Zaraibi male goats (Behery et al, 2015), lambs (Azizi-Shotorkhoft et al, 2016), buffaloes (Qamar et al, 2016) and in rabbits (Abdelhamid et al, 2017). The previous authors confirmed that CSL is a goodness source to improve body weight of livestock.…”

“…According to Behery et al (2015), they found that better protein in diet contained CSL had economical efficiency up to 151.44% than 110.68% in control diet nourished to Zaraibi male kids. On the other hand, Abdelhamid et al (2017) showed that diet supplemented with CSL at 10% achieved economic efficiency up to 20.07 compared to 17.74 in control rabbit. Hence, diets with moderate CP could be shared a reasonable to NEB was expected (Xu et al, 2017).…”

“…Kids in T2 could be achieved lower (P>0.05) consumption of water than kids in T1 and T3 in middle and late stage of trial (Table 3). Hence, the water consumption increased within advanced kids' age (Abdelhamid et al, 2017) and within changing in environmental conditions (Ahlberg et al, 2018). Also, the lowest water consumption with ration containing CSL may be related to available of energy source as given by Barreto et al (2012) who displayed that goats fed diet of high energy had significant decrease in consumption of water compared to those fed a diet of low energy.…”

“…In like manner, Azizi-Shotorkhoft et al (2016) recorded that blood total protein concentration was 6.71, 7.31 and 7.14g/dl and albumin was 2.72, 2.63 and 2.79 g/dl when lambs received rations contained 0, 50 and 100g/kg of CSL supplemented to dry matter, respectively. On the other hand, Abdelhamid et al (2017) reported that rabbit rations contained CSL could increased total protein and albumin. Enhance of total protein could relate to available carbohydrate source, impaired N utilization by rumen microbes thus, both N utilization as well as digestibility of CP were better as a result in serum protein (Mudgal et al, 2018).…”
