Wastes from apple processing industries cause environmental pollution, besides a substantial cost in treatment and disposal and represent a loss of valuable feed resource. Utilization of apple pomace as livestock feed is one of the possible alternatives to reduce environmental pollution and overcome the feed deficit especially in the temperate regions. High contents of fermentable carbohydrates, crude fibre and minerals increase its utility for feeding animals. However, low-protein content and nutrient digestibility along with restricted seasonal availability are some of the limitations. Apple pomace can be used as an energy source to replace conventional maize or cereals in the ration of ruminant species.

Herbal plants and their derived products are extensively used particularly in many Asian, African, and other countries of the world as they are considered as ideal feed additives because of their non-residual effect and ability to influence the ecosystem of gastrointestinal microbiota in a positive way. Further, the enzymatic treatment of these herbs helps in their efficient utilization by the host. Dandelion leaves and fenugreek seeds have been reported to have positive effect in terms of improving the performance of broiler chicken, but not much literature is available regarding their effect on gut histomorphology; therefore, the present study was conducted to explore the effect of these herbs either alone or in combination with or without enzyme treatment on histomorphology of liver and small intestine of broiler chicken. To achieve the envisaged objective, 273-day-old commercial broiler chicks were procured from a reputed source and reared together until 7 days of age. On the 7(th) day, the chicks were individually weighed, distributed randomly into 7 groups of 3 replicates with 13 chicks each. Birds in the control group were fed diets without additives (T1). The other six treatment groups were fed the basal diet supplemented with 0.5% dandelion leaves (T2), 1% fenugreek seeds (T3), combination of 0.5% dandelion leaves and 1% fenugreek seeds (T4), enzyme treated dandelion leaves 0.5% (T5), enzyme treated fenugreek seeds 1% (T6), and combination of enzyme treated dandelion leaves (0.5%) and (1%) fenugreek seeds (T7). The histomorphological study of liver and small intestines was conducted among different treatment groups. The results revealed the hepato-protective nature of both dandelion leaves and fenugreek seeds either alone or in combination with or without enzyme treatment when compared with the control group. Moreover, the histomorphological findings of jejunum revealed the beneficial effect of dandelion leaves, fenugreek seeds and enzymes on the intestinal mucosa in terms of cellular infiltration, architecture of villi, villus height/crypt depth ratio, thereby improving the intestinal health. The dandelion leaves and fenugreek seeds have hepato-protective nature and beneficial effect on the intestinal morphology particularly when included along with enzymes in the diet of broiler chicken.

20 male Corriedale sheep (3 months of age) were divided into 5 equal groups viz, T1, T2, T3, T4 and T5 and fed on measured quantity of concentrate mixture containing 0, 6, 12, 18 and 24% azolla replacing 0, 25, 50, 75 and 100% linseed cake respectively. Measured quantity of good quality oat hay was offered to all the groups as per their body weight to meet their requirement. Highest body weight was observed in T1 group and it had no significant difference with T2 group, but it had significant difference with T3, T4 and T5 groups. T2 group had significant difference with T5 group, but with other groups it had no significant difference in final body weight. Lowest body weight was observed in T5 group but it had no significant difference with T3 and T4 groups. Highest DM digestibility was observed in T2 group and lowest DM digestibility was observed in T5. But no significant difference was observed in DM digestibility among the groups. Lowest FCR was observed in T1 (control) followed by T2 group and they had significant difference with T3, T4 and T5 group, but no significant difference was observed between T1 and T2 group. Lowest cost of feeding per kg of gain was observed in T2 group and it had significant difference with T3, T4 and T5 group but not with T1 group (control). No significant difference was also observed among T3, T4 and T5 group but significantly higher cost of feeding per kg of gain than T1 (control) group was observed in T3, T4 and T5 group. It was concluded that azolla can be added in the diet of growing sheep at 6% level replacing linseed cake without any adverse effect on the performance of the animals.

The poultry population has increased exponentially from 13.9 billion in the early 21st century to 26.56 billion by 2022 worldwide, emphasizing the vital nutritional and economic part of this section. Simultaneously, the poultry sector faces a considerable amount of tests from diseases such as avian influenza, coccidiosis, mycoplasmosis, etc. that cost the industry multibillion-dollar losses each year. The groundbreaking and revolutionary possibilities of artificial intelligence and machine learning in poultry disease detection and diagnosis are discussed in this review. By capitalizing on data from physiological and behavioral traits like movement, vocalization, body temperature, and excreta, AI algorithms can detect indications of illness and pathological conditions, which means strengthening disease management and bringing down economic losses. High-precision image and video processing, non-invasive monitoring, the use of thermal imaging, and accurate tracking of poultry to spot health issues are some of the crucial developments that have also aided in analyzing stress and other abnormalities. Incorporating new-age technologies into feasible, applicable, and economical diagnostic tools that have the potential to transform poultry well-being, enhance the welfare of poultry, and upgrade production as well as handling processes is discussed here. The upcoming prospects include global partnerships, better data analytics, and extended research or studies for the management of diseases and behavioral anomalies in all poultry species. The collaboration of AI, machine learning, and biotechnology holds colossal promise for the poultry sector, guaranteeing food safety and ensuring public health.

| Blood metabolic profile (BMP) serve as clinical indicators for the impact of dietary manipulations on physiological health status. The present study was undertaken with the aim to assess the effect of in-feed supplementation of exogenous fibrolytic enzymes (EFE) cocktail as feed additive on BMP in lambs. Crossbred lambs (n=12) of 4-6 months age were distributed into two groups of 6 animals each and fed for a period of 90 days followed by 6 days metabolism trial. Animals in both the groups were offered complete feeds either supplemented with EFE cocktail @ 0.6% DM (Enz) or without any supplementation as control (Con). Haemato-biochemical parameters of animals in both the groups at start (0d) and subsequently at monthly intervals (30, 60 and 90d) were investigated. The EFE supplementation had positive significant (p0.05) effects of EFE supplementation on overall means of all blood cell indices except mean platelet volume (p<0.05) and platelet percent (p<0.01), energy metabolic profile, serum lipid profiles except low-density lipoprotein cholesterol (p<0.05) and atherogenic index (p<0.01), and hepato-renal functioning test profiles. The BMP of EFE supplemented lambs revealed better physiological health status compared to un-supplemented animals. It is concluded that inclusion of EFE cocktail in complete diets for lambs have no adverse effects on the haemato-biochemical parameter suggesting in-feed supplementation of the EFE to improve animals’s health conditions for successfully raising lambs intensively.
