Nutrients Digestibility, Nitrogen Balance and Blood Profile of West African Dwarf (Wad) Goats Fed Cassava Peels with Urea-molasses Multi-nutrient Block (UMMB) Supplements

Abstract

The nutrients digestibility, nitrogen utilization and blood profile of West African Dwarf (WAD) goat fed cassava peels with urea-molasses multi-nutrients block (UMMB) supplements was investigated in a twelve weeks experiment. Twenty WAD goats that weighed 8.33±0.35 kg on average were assigned to each of the five experimental diets that contained cassava peels without UMMB supplement (treatment 1) and with UMMB containing 0% urea (treatment 2), 5% urea (treatment 3), 10% urea (treatment 4) and 15% urea (treatment 5), in a completely randomized design (CRD). Results of the study revealed that nutrients digestibility were significantly (P<0.05) influenced by UMMB supplementation. Goats fed diet T 4 also had the highest values of digestibility coefficients of dry matter (DM), crude protein (CP), crude fibre (CF) and nitrogen free extract (83.05%, 71.97%, 67.64% and 71.34%) respectively. Nitrogen retention was significantly (P<0.

Effects of dietary supplementation with different concentration of molasses on growth performance, blood metabolites and rumen fermentation indices of Nubian goats

“…On the other hand, the significant increase in globulins accompanied by a decrease in A/G ratio in all molasses supplemented groups implies that molasses supplementation might enhance the humoral immunity response in Nubian goat kids. The improvement in serum protein parameters observed in the present study was in agreement with previous reports in Boer and local Mahari goats fed molasses/mineral blocks [ 14 , 22 ] and in West African Dwarf goats fed cassava peels with urea-molasses multi-nutrient block supplements [ 28 ]. Additionally, it has been concluded that dietary supplementation with urea-molasses mineral granules had no significant effect on albumin concentration in goat kids [ 13 ].…”

“…All hematological values were within the normal ranges for goats [ 25 – 27 ] suggesting that molasses supplementation had no adverse effects on both the hematopoietic and immune systems. Similar results have been reported in Boer and local Mahari goats fed molasses/mineral blocks [ 14 , 22 ] and in West African Dwarf goats fed cassava peels with urea-molasses multi-nutrient block supplements [ 28 ].…”

“…Similar result has been reported by Benavides and Rodriguez [ 31 ] who explained the reduction in ruminal pH in sheep fed increasing concentrations of molasses to the decrease in the salivary secretion in response to the lower fiber content of molasses. Interestingly, significant low ruminal pH has been reported previously in kids and adult goats [ 13 , 28 ], sheep [ 19 ] and calves [ 32 ] fed urea-molasses mineral granules, urea-molasses blocks, molasses and molasses/concentrate mixture. In contrast, an increase in ruminal pH in bulls and dairy cows fed different concentrations of molasses has also been reported [ 33 , 34 ].…”

“…However, the significant effect of MC × MD on ALT could be attributed to dietary adaptation. Similarly, it has been concluded that dietary supplementation with urea-molasses mineral granules or urea-molasses mineral blocks had no significant effect on AST and ALT concentrations in kids and adult goats [ 13 , 22 , 28 ].…”

Kecernaan Protein Kasar dan Serat Kasar Kambing Peranakan Etawa Jantan yang diberi Pakan Fermentasi Ampas Tahu dan Bungkil Inti Sawit dengan Imbangan yang Berbeda

“…Hasil penelitian ini sejalan dengan penelitian Cherdthong et al (2016) yang menyatakan bahwa kecernaan protein kasar bioetanol singkong memiliki rataan 69%. Ditambahkan oleh Gabriel et al (2018) bahwa kecernaan protein kasar kulit singkong dalam pakan kambing yaitu 50,28%. Hal tersebut dikarenakan kandungan nutrisi didalam kulit singkong lebih rendah dibandingkan pada daun singkong dan mempunyai kandungan HCN yang tinggi.…”
