This study aimed to evaluate the effects of organic acid (OA; Mold-Zap, Alltech, Nicholasville, KY) inclusion in total mixed ration (TMR) and feeding frequency TMR for lactating dairy cows on intake, total-tract apparent digestibility, sorting index, behavior, ruminal fermentation, milk yield composition, nitrogen balance, serum metabolites. Twenty-four Holstein cows, 4 with rumen cannulas, (me...

a complete diet (total mixed ration) with sorghum stover (40%) as sole roughage source was prepared and offered to animals under two forms: as mash or as expanded-extruded pellets (eep). these two complete diets were compared with a conventional diet (ad libitum chopped sorghum stover fed separately with concentrate mixture to meet 80% of protein requirements). these three diets were randomly a...

The study was conducted to determine the effect of dietary energy on milk yield and its composition under the influence of bovine somatotropic (bST) hormone in Nili Ravi buffaloes. Multiparous buffaloes (n=12) at mid lactation and similar level of production were selected and randomly divided into three groups (A, B and C) with four animals in each group in a completely randomized design. All t...

The present study was carried out to evaluate the effect of prill fat and rumen protected choline supplementation on daily dry matter intake, body weight changes and economics in lactating Murrah buffaloes (n=18) divided into three equal groups (Control, T1 and T2). Buffaloes in all the three groups were fed similar basal diet as total mixed ration comprising of berseem green fodder, wheat stra...

this experiment was carried out to study the effects of sainfoin (onobrychis viciifolia) as tannin source and different level of forage: concentrate ratio on digestibility, blood parameters, ruminal fermentation, milk yield and milk composition in milking ewes. therefore, eight lori milking ewes were alocated to factorial experiment base on the 4×4 replicated latin square design. four total mix...

This paper summarises six studies undertaken by the Sheep CRC to elucidate certain aspects of confinement feeding of sheep. A review of confinement feeding highlighted the variability of growth rate and feed conversion of sheep and revealed that little is known about the use of sorghum for feeding sheep. The review indicated that the main factors responsible for variation of growth rate and fee...
