Effect of pellet from total mixed ration on growth performance, blood metabolomics, carcass and meat characteristics of Bangladeshi garole sheep

Abstract

Six indigenous Bangladeshi Garole sheep (Ovis aries) (BW: 8±0.5 kg; Age: 1yr) were divided into two groups using a randomized block design to investigate the effect of total mixed ration (TMR) pellet feeding on growth parameter, blood metabolomics, carcass and meat characteristics. Control diet was composed of road side grass, rice straw, wheat bran, mustard oil cake, molasses, common salt which considered as loose total mixed ration (L-TMR) and treatment diet was pelleted form of L-TMR (P-TMR).In both the dietary treatments the animals were fed at 1.5 times of maintenance energy and protein requirement. P-TMR revealed a positive impact (p < 0.05) on live weight gain and feed conversion ratio than L-TMR. Total digestible nutrients (TDN) and digestible crude fibre (DCF) was significantly higher (p < 0.05) in P-TMR group whereas there was no significant difference (p < 0.05) in other digestible nutrients as well as plasma metabolites like plasma glucose, triglyceride, total cholesterol, HDL-cholesterol and LDL- cholesterol concentration between two dietary group. Dressing percentage and eye muscle area was significantly higher (p < 0.05) in P-TMR group but no significant difference was found between dietary treatments in term of disposition of body fat, proximate composition of mutton, all the sensory parameters except tenderness and overall acceptability. So, it could be concluded that, the P-TMR might be fed to sheep for better growth performance and higher meat production rather than production of functional mutton.Progressive Agriculture 28 (3): 222-229, 2017

Resilience of Lambs to Limited Water Availability without Compromising Their Production Performance

“…Such gain may be attributed to the prevailed Ta on one hand and the diet type (pelleted diet) on the other hand. Numerous studies have substantially shown that the processing methods of reducing the physical form of forages used in pelleted diet have effects on the rate at which digesta leave the rumen, which in turn controls voluntary feed intake, digestibility, and utilization [36][37][38].…”

Pelleting of a Total Mixed Ration Affects Growth Performance of Fattening Lambs

“…This led to the recent trend to offer partially or completely pelleted TMR to dairy cows and heifers in some regions of the world ( 5 – 7 ). The use of pelleted TMR has also been reported for goat ( 8 , 9 ) and sheep production ( 10 – 13 ).…”

Effects of feeding ground versus pelleted total mixed ration on digestion, rumen function and milk production performance of dairy cows

“…Accordingly, increased DMI and DM digestibility for PTMR cows resulted in a higher ADG and a lower FCR, which was consistent with findings when a PTMR was fed to meat sheep (Islam et al . ). The cost associated with pelleting TMR was 20 US dollar per tonne feed, including manual work, water, electricity and machinery depreciation, but more costs associated with transportation, storage and labour were accordingly saved by using PTMR in this study.…”

“…However, altering the form of feeds did not change blood metabolomics between GTMR‐fed versus PTMR‐fed sheep (Islam et al . ). In this study, dietary treatments did not cause significant effects of PTMR on blood metabolites, but PUN and glucose concentrations increased over feeding period.…”

“…Comparing with GTMR, the use of PTMR not only offers many practical advantages, including full use of local feed resources (including agro‐industrial by‐products, crop residues and unconventional nonpalatable feed resources), it saves storage spaces and transportation costs and minimises labour, but also exerts both positive physiological benefits and negative effects, including increasing growth performance and dressing percentage of ruminants but reducing chewing time (Islam et al . ). However, the major drawback of PTMR is higher processing cost for hard and long fibre forages; another drawback is lower rumen pH due to lack of physically effective NDF and high percentage of concentrates (Zhong et al .…”
