 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Feeding Total Mixed Fiber on Feed Intake and Milk Production in Mid-Lactating Dairy Cows) ผู้เขียน:วรินธร มณีรัตน์, ดร.สมเกียรติ ประสานพานิช, รองศาสตราจารย์, พงศ์ธร คงมั่น, Wirat Sinsmut, ดร.ศรเทพ ธัมวาสร, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThis study determined the effect of total mixed fi ber (TMF) from agro-industrial by-products as a roughage source for lactating dairy cows on digestibility, milk yield and milk composition. A completely randomized design was employed on fi fteen 87.5% Holstein Friesian crossbreds in mid lactation. All cows had an average initial body weight of 416.03?34.66 kg and 115.20?20.32 days in milk. Cows were randomly allocated to three treatments (T1 = cows fed pineapple peel silage with rice straw (PS) ad lib; T2 = cows fed TMF ad lib; T3 = cows fed TMF ad lib and 1 kg less of concentrate (TMF-1). All cows were fed with 20.35% crude protein (CP) of commercial concentrate feed. The results revealed that the total dry matter intake of the PS group was higher than those of cows fed with TMF and TMF-1, respectively (P < 0.05). The apparent digestibility of dry matter (DM), organic matter, crude protein, neutral detergent fi ber and acid detergent fi ber in cows fed PS was lower (P < 0.05) than with TMF. Estimated energy intake of diet with PS (1.71 ? 0.15 Mcal per kilogram DM) was lower (P < 0.05) than energy fed with TMF (2.34?0.13 Mcal per kilogram DM) and TMF-1 (2.26?0.25 Mcal per kilogram DM). The milk yields of cows fed TMF and TMF-1 (14.55?1.95 and 14.32?1.76 kg.d-1) were higher than cows fed PS (P < 0.05). However, the milk composition was not signifi cantly different (P > 0.05) in all treatment groups. |
