    STUDIES ON USE OF SOME PHYTOGENIC MATERIALS AS CATTLE FEED PRESERVATIVES.
    (CSKHPKV, Palampur, 2019) Rana, Divya; Rani, Daisy
    This study was conducted to generate information regarding use of some phytogenic materials as cattle feed preservatives with the objectives to study changes in chemical composition of concentrate feeds preserved with plant materials; to study the effect of preservatives on in-vitro digestion of feeds; to study effect of promising preservative on nutrient utilization in ruminants and to study the economics of use of preservatives on growth performance of calves. Calcium propionate @ 0.1 percent, curry leaves @ 2 percent, mint leaves @ 1 percent, seabuckthorn leaves @ 2 percent, eucalyptus leaves @ 2 percent, turmeric rhizome powder @ 1 percent and neem leaves were added @ 2 percent and they were designated as PC, C, M, S, E, T and N, respectively. Basal feed was designated as NC. Effect on physical and chemical composition of feeds was studied up to 6 months period. In-vitro gas production study was conducted bimonthly for dry matter and organic matter digestibility. Digestibility-cum-metabolism trial was conducted by using NC, PC, N and T with wheat straw as source of roughage in 4 groups of calves with 5 calves in each group. A growth study was conducted on same groups of growing calves for 12 weeks period by using TMR containing concentrate with PC, N and T. Economics of use of the phytogenic preservatives in growing calves was calculated. On the basis of effect of phytogenic preservatives on shelf-life of concentrate feeds, treatment T and N had rank 1 followed by PC; M and S; C; NC and E in decreasing order. The feeds could be very well preserved up to 4 months after preparation under the weather conditions of Palampur, without affecting the in-vitro digestibility of DM and OM. The treatment T significantly (P<0.05) increased the digestibility of OM, CF and NFE in the growing calves. Nitrogen retention was not affected by the use of PC, N and T. Energy content of feeds of N and T treatments were significantly (P<0.05) higher than NC. The use of Calcium propinate, Neem and Turmeric resulted in lowering the expenditure of feeding to get 1 kg body weight by 10.65, 8.59 and 6.53 percent, respectively compared to NC. As the shelf-life study was conducted from February to August, there was a great change in environmental condition during last 2 to 3 months due to monsoons, therefore research work is needed to be conducted on the effect of phytogenic preservatives on shelf-life of feeds which are prepared and stored during rainy season.

    NUTRITIONAL EVALUATION OF SOME  PROBIOTICS ON  THE BIOLOGICAL PERFORMANCE  OF BROILER CHICKEN UNDER VARIED STRESS CONDITIONS.
    (CSKHPKV, Palampur, 2009-10-16) Katoch, Shivani; Sharma, K.S.
    ABSTRACT Use of antibiotic growth promoter feed additives for animal production has been prohibited in most of the developed countries. Therefore, in the post antibiotics ban era, there is a need to look for alternatives, which can safely and efficiently replace antibiotics as growth promoters in poultry. The broad objective of the experiments were to determine the effect on biological performance of broiler birds offered diets containing low density protein, calcium and phosphorus by supplementation of direct fed microbial (DFM)/ probiotics isolated from leopard feces both under normal and stressful management conditions. After, isolation, purification and culturing of direct fed microbial from leopard feces procured from Gopalpur Wildlife natural Park – Palampur, the microbes/ DFM (Probiotic) namely Lactobacillus and Streptococcus were offered in low density nutrient viz. protein, calcium and phosphorus, formulated diets to broiler birds in sequentially conducted trials of 3 batches from 1 to 42 days of age under varied management protocols devised. It was found that that DFM supplemented broiler birds offered experimental formulated nutrient (Ca and P) deficient diet reared as per standard and poor management protocol exhibited higher growth and biological performance viz. low cholesterol, higher dressing percentage and low mortality by maintaining a higher count of beneficial microflora in the gastrointestinal tract and increase in nutrient utilization (Ca and P) through improved intestinal enzyme activities and nutrient availability. Effect of isolated DFM/probiotic was more pronounced when the birds were offered mineral (Ca and P) deficient (10 and 20%) diet Similarly supplementation of isolated DFM to broiler birds offered experimental formulated protein deficient diet could not overcome stress because of multiple managemental stress factors leading to poor colonization and growth and thus could not exert competitive exclusion vital to over come stress. Further, it was found that isolated DFM/Probiotics did not support the broiler birds to grow to its full genetic potential when challenged with multiple nutritional and management stress factors. At the farmer level supplementation of isolated DFM to the broiler birds significantly (P<0.05) improved the feed conversion ration and exhibited numerically higher gain in weight.

    EFFECT OF FEEDING SEABUCKTHORN CAKE (HIPPOPHAE L.) ON EGG PRODUCTION IN POULTRY AND GROWTH IN CALVES
    (CSKHPKV, Palampur, 2011-11-16) MD., HASANUZZAMAN; Sharma, V.K.
    ABSTRACT Balanced 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. Three 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. The 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. Looking 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.
