A study was conducted to analyse the migratory sheep production system in southern agro-climatic zone of Tamil Nadu. A total of 100 migratory sheep farmers were randomly selected for the study and divided as small (< 175), medium (175- 350) and large (> 350) flocks based on the average flock size for comparison. The migratory tracts were identified based on the results of the enquiry from the sheep farmers, animal husbandry department personnel and by direct identification. A total number of 78 migratory tracts comprising 28 major and 50 minor tracts were identified in the study area. The mean radial distance (km) of migration in major tracts was 317.00±6.21 and minor tract was 148.40±6.21. 

This experiment was carried out to study the effect of frozen storage on the physico-chemical quality of quail breast meat. Six weeks old broiler quails were collected, slaughtered, dressed hygienically. Quail breast meat samples were collected from dressed carcass which was packed in low density polyethylene pouches taking optimum care to avoid contamination and stored at -18 ± 20 C for 60 days.  Fresh as well as frozen quail breast meat samples were evaluated for physico-chemical and histological changes. Frozen meat samples were analyzed after thawing at 4 ± 10 C for 12 hrs at an interval of 15, 30, 45 and 60 days. It was observed that with advancement of the frozen storage period pH, TBA value, tyrosine value and drip loss increased, whereas moisture, protein, fat and ERV content of quail meat decreased. Pronounced structural changes reported at later part of storage in histological study due to formation of ice crystals in the muscles. It shows that quail meat can be safely stored for 60 days in frozen state without any marked changes.

Meat tenderization is the disruption of meat structure, breaking the collagen subsequently resulting in good palatability and acceptance by consumer. Tenderization could be achieved by the traditional method of ripening for a long period in controlled temperature with due precautions to prevent meat spoilage. In this process endogenous muscle enzymes viz. calpains, cathepsins and caspases are responsible for proteolysis of muscle. Other processes adopted for tenderization include use of electricity, heat, physical force (hydrostatic pressure), ultrasonic waves, shock waves in water (hydrodyne), enzyme action, use of vitamins, ionic compounds, mineral salts, and chemical compounds. The electrical stimulus of low voltage is more popular than high voltage due to the cost involved. Like endogenous enzymes, plant based exogenous enzymes also cause tenderization, but their activity should be monitored to avoid over-tenderization. Chemicals, vitamins and ionic compounds activate the calcium-dependent proteases and lysosomal enzymes, which are responsible for tenderization. 

The main aim of this study was to investigate the effect of different concentrations of glutathione supplementation on liquid storage of Surti buffalo bull semen. This study was performed on adult Surti buffalo bull (n = 6), and seminal ejaculates (24) were collected and evaluated for various microscopic seminal quality parameters for further processing. After preliminary evaluation, ejaculates of each collection session were mixed and divided into four equal aliquots. All the aliquots were diluted (1:10) with Tris fructose egg yolk citrate extender contained glutathione served as control (T0), whereas the other three aliquots were supplemented with 0.5, 2.0 and 5.0 mM glutathione which were grouped as Treatment-1 (T1), Treatment-2 (T2) and Treatment-3 (T3), respectively. Thereafter, the samples were stored at 4 ºC for 4 h, and various seminal parameters (individual sperm progressive motility, viability, abnormalities, plasma membrane functionality) were evaluated at equilibration. The results indicated that the mean percent values for pre-freeze sperm progressive motility, live sperm percentage and HOS responsive spermatozoa were found to be significantly higher (P<0.05) (except individual progressive motility which was non-significantly higher in Treatment-3); whereas sperm abnormalities were significantly lower (P<0.05) in semen samples treated with glutathione (Treatment-1, Treatment-2 and Treatment-3) in comparison to control. The Treatment-2 (2.0 mM glutathione), had the highest pre-freeze sperm progressive motility percentage, live sperm percentage, HOS response sperm percentage and reduced sperm abnormalities percentage compared to other three groups.

In recent years, investigations have been carried out to improve the functional value of meat products through the introduction of dietary fibre (DF). The addition of dietary fibre in meat products contributes to the fabrication of products that enhance physiological functions. The present study was conducted to fortify chicken meatballs with Oats (Avena sativa) and Cabbage (Brassica oleracea) as a source of dietary fibre. Oat flour and cabbage were incorporated at the levels of 1.5 %, 2.5 % and 3.5 % (w/w) for the preparation of meatballs. Moisture content, product pH, emulsion stability and technological properties like cooking yield, water absorption capacity and oil absorption capacity of the final product were studied. The results revealed that cooking yield increased on the addition of oat flour and cabbage (p≤0.05). There was no significant change in product pH, and in sensory attributes at the level of 2.5% incorporation. Overall technological properties and sensorial analysis of these products were found to be higher than control. Thus, the inclusion of oat flour and cabbage at the level of 2.5 % to chicken meatballs had significantly increased the crude fibre from control 14.053+0.021 to 4.727±0.015% in T2, representing a l6.62% increase in fibre content, that also showed higher desirability in sensorial analysis.

The study was conducted in Udaipur district of Rajasthan state selected purposely keeping in view of the fact that the district has highest population of  livestock in southern Rajasthan. A sample of 120 respondents was selected for the present study. The results indicated that a majority of farmers had medium level of Coordinating ability. Half (50%) of the small dairy farmers were found to have medium level of Planning ability while majority of medium category of dairy farmers had medium level of decision-making ability whereas in case of large farmer’s category, 58.82% of them exhibited high level of risk of dairy farming enterprise. The correlation analysis revealed the independent variables viz age, education, annual income, training, occupation, scientific orientation, extension and mass media were positively and significantly correlated with farmer’s Coordinating ability. However,  education, training, annual income, economic motivation, scientific orientation, market orientation, mass media were found to have positively and significant correlation with Planning ability of the respondents. The determinants, training, occupation, extension, annual income, mass media, economic motivation and scientific orientation were important variables which influenced Coordinating ability and Planning ability of dairy entrepreneurs.

A 3 year old Spitz- Pomeranian mixed breed was presented with a history of bilateral hind limb lameness and walking in abnormal gait since birth. Radiographic diagnosis revealed bilateral lateral luxation of patella with deformity of both stifles. Surgical correction of congenital deformity was done on right hind limb using the technique of trochlear wedge resection sulcoplasty (TWRS) and transposition of tibial tuberosity (TT) which showed normal weight bearing and good functional outcome on 50th post-operative day.

Foetal mummification is a common condition in swine. A four year old Large White Yorkshire sow gave birth to one mummified foetus along with 7 normal live foetuses in 4th parity.

The total meat production in India is 9.29 million out of which 4.78 million tonnes is from poultry and the growth of poultry meat sector has increased by 6.86 % over previous year. The growth rate of backyard poultry population from 2012 to 2019 (45.79 %) is ten times higher than when compared to commercial poultry (4.50 %) (BAHS, 2022). The native chickens are slowly growing in nature and are preferred for better flavor and for the belief that natural, less intensive management systems provide desi birds with higher welfare levels, resulting in much better product quality and great demand. The meat from native chicken is more delicious and provides nutritional security and economic support for the rural and most suited for backyard system of rearing. The aim is to study the carcass traits of available native chicken in India and compare it with native chicken at Hosur. The carcass characteristic of the native chicken variety at Hosur was evaluated by sacrificing 25 birds of each sex at 16 weeks of age. The observed results were compared with the performances of other varieties of native chicken in India with respect to the parameters like New York dressing yield, eviscerated yield, Ready to cook yield, cut-up parts yield, Meat bone ratio and Giblets yield at each sex of the bird at different age of slaughter especially at 16 weeks of age. It helps to identify the variety of native chicken which had good carcass traits and could be utilized for table delicacy.

The current study utilized 20 postpartum anestrus buffaloes maintained at an organized dairy farm in Vuyyuru, Krishna district to compare the metabolic (glucose), mineral (calcium) and anti-oxidant (superoxide dismutase) levels in ovsynch-48 (n=10, G48) and ovsynch-56 (n=10, G56) postpartum anestrus graded Murrah buffaloes. G48 group of buffaloes received 20 µg of GnRH on Day 0, followed by 500 µg PGF2 on Day 7, a final dose of 20 µg of GnRH was given 48 hours after PGF2α on Day 9. Whereas, G56 group of buffaloes received 20 µg of GnRH on Day 0, followed by 500 µg of PGF2α on Day 7, a final dose of 20 µg GnRH was given 56 hours after PGF2α on Day 9. In both groups, FTAI was performed at 16-21 hours interval after observing estrus. Results revealed that on different days of treatment, serum glucose and calcium levels did not differ significantly (P>0.05) in both treatment groups; however, Superoxide dismutase levels varied significantly (P<0.05) on different days of treatment in both groups. The results of the study parameters could play pivotal role in reproductive function and may provide insights into the underlying mechanism of anestrus.
