 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Performance, Hematology and Serum Biochemistry of West African Dwarf Goats Fed Ensiled Mixtures of Elephant Grass (Pennisetum purpureum) with Lima Bean, African Yam Bean and ผู้เขียน:Ajayi Festus Tope, Ogunleke Funmi, Adesina Adewumi, Durotoye Emmanuel Sunday สื่อสิ่งพิมพ์:pdf AbstractThe performance, hematological and biochemical parameters of 16 West African dwarf goats fed ensiled elephant grass (Pennisetum purpureum) with pineapple pulp (Diet 1), pigeon pea plant (Diet 2), lima bean plant (Diet 3) and African yam bean plant (Diet 4) were investigated in a completely randomized design. Four goats were allotted to each diet in a 91-day feeding trial; each goat was fed at 5% of its body weight. The results showed that the crude protein, ether extract and ash contents of Diets 2–4 were similar (P > 0.05). The dry matter intake, crude protein intake and neutral detergent fi ber intake of goats fed Diet 3 differed signifi cantly (P < 0.05) from that of goats fed Diets 1, 2 and 4 which were 71.2, 28.8 and 52.7 g per kilogram W0.75 per day (metabolic weight per day), respectively. The highest packed cell volume was observed in goats on Diet 2 (29.3%) and differed signifi cantly (P < 0.05) from that of goats fed Diets 1, 3 and 4. Goats fed Diet 3 had the highest hemoglobin concentration, lymphocyte, monocytes and eosinophils. Goats fed Diet 4 had the highest total protein (70.2 g.L-1) and cholesterol (42.0 mmol.L-1).The highest urea nitrogen (3.8 mmol.L-1), creatinine 97.0 ?mol.L-1), AST (51.9 IU.L-1), ALT (6.7 IU.L-1), glucose (3.1 mmol.L-1) and lowest cholesterol (31.2 mmol.L-1) were observed in goats fed with Diet 3. These results indicated that ensiling elephant grass with any of these legumes known to contain high concentrations of anti-nutrients was not detrimental to the health of the goats. Diet 3, comprising ensiled elephant grass with lima bean and pineapple pulp, produced the optimal growth rate and weight gain in the goats. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Dry Season Cutting Management on Subsequent Forage Yield and Quality of Ruzi (Brachiaria ruziziensis) and Dwarf Napier (Pennisetum purpureum L.) in Thailand) ผู้เขียน:Tadesse Tekletsadik, ดร.สายัณห์ ทัดศรี, ศาสตราจารย์, นางสุนันทา จันทกูล, ผู้ช่วยศาสตราจารย์, ดร.สมเกียรติ ประสานพานิช, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractA field study was conducted under rainfed conditions during 2002 – 2003 to determine the effect of dry season cutting management on the yield and quality of ruzi (Brachiaria ruziziensis) and dwarf napier (Pennisetum purpureum) grass during the dry season and the following wet season. The pastures were cut 1, 3, 6 times during the dry season and 7 times during the following wet season at 5 and 20 cms above ground level. The study was sited on a reddish brown sandy clay loam soil at Suwanvajokkasikit Field Crop Research Station in the Pakchong district of northeast Thailand. During both dry and wet seasons, leaf production and total plant production of dwarf napier were noticeably higher than ruzi grass but similar in stem production. Lax cutting (20 cm) produced significantly higher yield than close cutting (5 cm) and cutting every 2 months (3 times) tended to give higher yields than cutting more and less frequently of dwarf napier grass but not of ruzi. However, in the following wet season the pastures cut only once during the dry season produced significantly higher yields of herbage than those defoliation more frequently, particularly in the case of dwarf napier. The protein percentage in dwarf napier and ruzi grass was not significantly different, although tended to be higher in dwarf napier particularly during the wet season and in the stem fraction. Protein yields, however, between the two grasses were highly significant with dwarf napier yield being much higher than ruzi, which was largely a reflection of the respective dry matter yields. Both pasture species showed higher protein yields under lax cutting than close cutting in both seasons. Lax cutting also tended to produce higher neutral detergent fiber (NDF) and acid detergent fiber (ADF) content in the total herbage than close cutting and in both seasons. NDF and ADF concentration significantly increased with delayed time of cutting in the dry season. |
