Utilization of low quality agricultural by-products for making silage from 1st cut of Berseem (Trifolium Alexandrinum, L.) in a comparative study by sheep and goats
Abstract: Ten digestion trials were conducted on Rahmani sheep and Zaraibi goats, five trials each to study the effect of mixing five agricultural by-products (ag-by) being rice straw (RS), wheat straw(WS), rice hulls (RH), bean straw (BS) and corn stalks (CS) along with berseem clover (BC, 1st cut ) (25 ag-by: 70BC) plus crushed yellow corn (YC) (5% ) when making silage on chemical composition, silage quality, feed intake, nutrients digestibilities and nutritive value of obtained silages with both species. Therefore, five types of silages were formulated and will be referred to as BRS,BWS,BRH,BBS and BCS according to the corresponding sequence of previous ag-by materials, respectively.
The main results indicated that the CS and BS and their silages (BCS and BBS ) had the highest CP,OM and GE concentration, while the lowest values were observed with RH and its silage (BRH) and those of WS and RS and their silages fell intermediate. The BS and its silage and BC contains much less fiber constituents than do gasses (RS,WS,CS and RH) and their silages, but the reverse picture was true in case of non fiber carbohydrates (NFC) content. All kinds of silages had normal values of pH(4.13-4.75) and similar totalVFA’s concentration (1.71-80%) with somewhat less amount of lactic acid (1.3%) in BRH silage, compared with other ones. Dry matter intake (DM), nutrients digestibilites and nutritive values were significantly differed (P<0.05) among treatments as well as between the two animal species, but they were not significantly affected by their interaction. In most cases the highest DMI, nutrients digestibilites and nutritive value expressed as TDN and DCP content was recorded with BBS and BCS silages, followed by these of BRS and BWS silages, being the lowest for BRH one. Goat consumed (P<0.05) more DMI (g/kg BW g/kg W0.75) and had higher (P>0.05) DM, OM, CF, CP and EE digestion coefficients as well as nutritive value (P<0.05) of silages expressed as percentages or as TDN intake as g/kg BW or g/kg W 0.75 than sheep. It could be concluded that mixing the 1st cut of berseem (70%) with chopped CS, BS, WS and RS (25%) plus YC (5%) may be help in producing good quality silages to be fed at the period of green shortage during summer season. Goals appeared to be more efficient in utilizing the obtained silages than sheep.
