“…Gulseker, M81-E, No91, Grassi and P1579753 genotypes had significantly greater NDF contents than Dale and Tracy genotypes. In previous studies, NDF contents of sweet sorghum genotypes were reported as between 32.6 -62.5% (Mohammed and Mohamed, 2009;Machado et al, 2012;Neto et al, 2017;Vinutha et al, 2017). Our findings were in the range of values given in the mentioned reports.…”

This study was conducted to determine biomass yields and feed quality parameters of 21 different sweet sorghums (Sorghum bicolor var. saccharatum (L.) Mohlenbr.) genotypes grown as the second crop after wheat harvest under Cukurova conditions. Field experiments were conducted at the experimental fields of Dogankent-Adana location of Eastern Mediterranean Agricultural Research Institute in randomized blocks design with 4 replications in the years 2016 and 2017 (June-October). According to the results of the variance analyses of tha data obtained from the experimenst, years, genotypes and year x genotype interactions had significant effects on investigated parameters. Averaged over two years, dry matter yield (DMY), days to 50% flowering, crude protein content, NDF, ADF, and RFV of the genotypes varied between 21.6 and 62.9 t ha -1 , 55.0 and 99.1 days, 3.66 and 5.43%, 41.78 and 52.42%, 29.14 and 37.72%, and 111.3 and 148, respectively. It was determined that Ramada, Roma, Topper 76, UNL hybrid-3 and No91 genotypes were identified as late genotypes with DM yields of greater than 51 t ha -1 ; Ramada, Roma and Topper 76 genotypes had the first places in terms of quality and they were superior than the other standard cultivars and genotypes.

“…As reported by Gidenne (2000) the rabbit has a low utilization of the fibrous fraction due to the rapid passage of feed through the gastrointestinal tract. However through the caecotrophic activity, the digestibility of nutrients, especially protein, is incremented ( Machado et al, 2012 ).…”

This study aimed to evaluate the nutrient digestibility of growing rabbits fed diets with different levels of either Leucaena leucocephala (LLM) or Moringa oleifera (MOLM) leaf meals and also to compare total collection and TiO2 marker methods for estimating digestibility. A total of 30 California growing rabbits (1.81±0.19 kg live weight on average) were randomly distributed into five experimental groups of six rabbits each and were housed in individual cages. The groups were control, 30% LLM, 40% LLM, 30% MOLM, and 40% MOLM. All groups received pelleted diets for two weeks; diets also contained 4 g/kg titanium dioxide as dietary marker. Daily feed intake was recorded during the whole experimental period and total feces were collected daily and weighed individually during four days. The results showed that there were no difference (p>0.05) in feed, dry matter (DM), organic matter (OM), crude protein (CP), digestible energy, and crude fiber (CF) intake between the control group and the other experimental groups. The apparent digestibility values of DM, OM, CP, CF, acid detergent fiber, and gross energy were the highest for control group (p = 0.001), meanwhile MOLM diets had generally higher nutrient digestibility coefficients than LLM diets. Increasing the inclusion level of leaf meal in the diet from 30% to 40% improved the digestibility of CF from 45.02% to 51.69% for LLM and from 48.11% to 55.89% for MOLM. Similar results for apparent nutrient digestibility coefficients were obtained when either total collection or indigestible marker method was used. In conclusion, the digestibility of MOLM containing diets were better than LLM diets, furthermore TiO2 as an external marker could be used as a simple, practical and reliable method to estimate nutrients digestibility in rabbit diets.

“…Its tuberous roots, rich in starch, are used in human and animal feeding. Several cassava by-products may be used in rabbit diets (Omole, 1990) including the cassava foliage hay (Scapinello et al, 1999;Faria et al, 2008), leaf meal (Machado et al, 2012), root meal Oso et al, 2010) and root peel meal Ekpo et al, 2009). …”

Digestible energy of unpeeled cassava root meal and its effect on growth performance and carcass traits in rabbits

Two experiments were conducted to evaluate the use of cassava root meal (891 g dry matter [DM]/kg, 639 g starch/kg, 74.1 g neutral detergent fibre [NDF]/kg, and 26.6 g crude protein [CP]/kg) in diets for growing rabbits. In the first experiment, a basal diet (419 g NDF/kg and 181 g CP/kg) and a test diet, in which cassava replaced 25% of the DM of the reference diet, were used. Twenty 50-d-old New Zealand White rabbits weighing 1474±10 g were randomly assigned to the 2 treatments, and digestibility of DM and gross energy (GE) were determined. The inclusion of cassava root meal in the diet increased DM digestibility (67.0±0.80 vs. 58.0±1.12%, P<0.01) and digestible energy (DE) content (11.86±0.16 vs. 10.45±0.22 MJ/kg, P<0.01). Digestible DM and DE contents of the unpeeled cassava root meal, obtained by the substitution method, were 943.3±15.8 g/kg and 15.28±0.32 MJ/kg. In the second experiment, 5 experimental diets were formulated to contain 150 g CP/kg, 184 g acid detergent fibre/kg and 10.9 MJ DE/kg, and increasing levels (0, 7, 14, 21 and 28%) of unpeeled cassava root meal, mainly in substitution of corn. A growth trial was carried out using 90 rabbits from the Botucatu genetic group from weaning (35 d, weighing 951±13 g) up to 71 d of age. The rabbits were housed in pairs, and randomly assigned to the 5 treatments (9 replicates/ treatment). No effect of the substitution of corn with cassava root meal was detected on growth performance (growth rate, feed intake and feed conversion ratio, on av. 44.6±0.50 g/d, 132±1.4 g/d and 2.97±0.028 g/g, respectively). The level of inclusion of cassava root meal had a quadratic effect (P=0.005) on the dressing out percentage, showing a minimal value (51.2%) for inclusion of 139 g/kg. No other effect was observed on slaughter and reference carcass weights (2383±19 and 1238±11 g, respectively). Unpeeled cassava root meal may be used to completely replace corn in the diet, supporting high performance in growing rabbits, but its effects on carcass traits should be investigated further.
