Abstract: newline ABSTRACT newlineBalanced and effective feeding are the most important prerequisites for economic production of livestock and poultry. So, minimization of feed cost would be a great achievement for livestock and poultry farmers if the unconventional but potential ingredient like Seabuckthorn (SBT) cake would be introduced as the replacer of major protein sources, as nutritionally, SBT cake is very rich in proteins, fat, amino acids, vitamins and minerals. Very little systematic and scientific work has been conducted to study the effects of feeding SBT cake to the livestock and poultry. Hence, the present study was envisaged to see the effect of replacement of CP of conventional feed of layers and calves, with that of SBT cake to evaluate biological performances, nutrient utilization, rumen metabolites and cost benefit ratio by feeding SBT cake. newlineThree experiments were conducted to study the effect of SBT cake on layers and calves production. First trial was conducted in 360 BV-300 layer chicks which were offered conventional rations in control (S0) group and replacing 10, 20, 30, 40 and 50 per cent CP by SBT cake CP. The second experiment was aimed to study the effect of SBT cake on growth of calves where 18 calves of 4-5 months age were divided in 3 treatment groups having 6 animals in each group. The conventional CGR was offered in control group (SBT0) and replacing 50 per cent and 75 per cent CP of the control group with the CP of SBT cake in SBT50 and SBT75 groups respectively. One more trial was conducted as a third experiment, aimed to observe the effect of SBT cake on rumen metabolites and rumen microbial population in adult cattle. Three adult cattle (fistulated) were maintained on three rations with a switch over design. The crude protein contents of the basal ration (T1) were replaced with SBT cake CP at 50 (T2) and 75 (T3) per cent CP in the adult cattle ration. newlineThe egg production, egg mass and body weight gain of layers were higher in S20 group where 20 per cent CP of conventional concentrate was replaced with the CP of the SBT cake. FCR in respect of egg mass as well as biological performance of the layer was found better in S20 treatment group. It was noticed that, as the level of SBT cake increased beyond 20 per cent, the biological performance of the layers declined though the quality traits of eggs were not affected by replacement of SBT cake at any level. It was revealed that replacement of CP of conventional layer feed with SBT cake CP up-to 20 per cent level was economic for layer production. Higher body weight gain and better balance of nutrient in calves was observed in SBT50 group where 50 per cent CP of the traditional CGR was replaced with the SBT cake CP. Better FCR of calves was found in SBT50 group, hence, can be considered as the highest dose of replacement with SBT cake CP in CGR. Higher microbial population in older calves was found in T2 group, where 50 per cent CP of the traditional adult calves ration was replaced with the CP of SBT cake. Better rumen metabolites were also found in the T2 group. newlineLooking at the results of present investigations, it could be concluded that 20 per cent CP of the traditional concentrate ration could be replaced with the CP of SBT cake in layer birds for a viable and cost effective egg production, whereas, 50 per cent CP of the traditional calves ration could be replaced with the CP of SBT cake in young as well as older calves to improve the nutrient utilization efficiency for sustainable livestock production. newline
