A comparison of milk yield and composition of various indigenous and crossbred cattle was undertaken to evaluate their performance in the subtropical high altitudes of Kerala. A total of 173, 95, 63 and 63 morning milk samples from 42 CBHF, 12 Vechur, six Sahiwaland six Kankrej cows of early second lactation were analyzed for total solids, fat, solids-not-fat, lactose, protein and chloride by conventional  methods. Least squares analysis revealed that breed and test-day climate significantly influenced the milk yield and composition (P >0.05). The mean lactation yield in Vechur, Sahiwal, Kankrej and CBHF were 514.62 ± 42.87 Kg, 1025.65 ± 358.15 Kg, 1102.45 ± 358.15 Kg and 1763.93 ± 128.16 Kg respectively. Kankrej had higher fat and total solids while Vechur had higher SNF, protein and lactose (P >0.05). Vechur had lesser seasonal fluctuations in major constituents, indicating it’s adaptability and climatic resilience as the native breed of Kerala.

Methane (CH4) is second major gas after carbon dioxide (CO2) responsible for the warming of environment and ozone layer depletion. Although CH4 production is necessary for efficient digestion, it represents an energetic loss of up to 12% of the gross energy intake in ruminants. Methane is produced by strict anaerobes belonging to the sub-group of the Archaea domain. The past decade has shown a lot of interest in the use of plant extracts to mitigate methane production in ruminants. Addition of plant essential oils, can limit the growth of the micro-organisms participating in methane formation in the rumen, thus resulting in the reduction of its production. Reduction of methane production in the rumen ecosystem is possible to achieve with the use of plantsaponins. Tannins have been found to be toxic for many of the rumen microbes, especially ciliate protozoa, fibre degrading microbes and methanogenic bacteria as a result of this methanogenesis in the rumen is reduced. 

The selection of breeding bucks stands as a pivotal decision in both organised and field populations aiming for genetic enhancement. Incorporating bucks with high genetic merit into breeding programme holds the potential to significantly elevate the overall productivity of the stock. This, in turn, serves to augment the economic viability of rural goat keepers who adhere to zero-input management systems. Hence, gaining a comprehensive understanding of the influence exerted by non-genetic factors on semen characteristics among bucks within a particular breed is imperative for effective breeding management. In this study, a total of 108 ejaculates from four adult Kanni Adu bucks were analysed to determine the effect of season and order of the ejaculate on conventional semen attributes using linear mixed models with lme4 package in R software. The estimated marginal means for semen volume (ml), sperm concentration (million per ml), mass activity (0 to 5 scale), initial, pre-freeze and post-thaw sperm motility (per cent) were 0.623 ± 0.056, 3841.00 ± 238.00, 4.73 ± 0.08, 86.87 ± 0.02, 85.49 ± 0.01 and 56.15 ± 0.01 respectively.

The current study was designed to evaluate the carcass and meat quality characteristics of Siruvidai chicken of Tiruvannamalai, Dharmapuri, Ariyalur and Perambalur districts of Tamil Nadu.  The carcass characteristics namely New-York dressed weight, eviscerated carcass weight, ready-to-cook weight, giblets weight, abdominal fat weight and meat: bone ratio were recorded. No significant differences observed in carcass characteristics among the districts except for pre-slaughter weight and breast yield. A significantly (p ≤ 0.05) higher breast yield was recorded from Ariyalur and Perambalur districts. The pH, water holding capacity, shear force value, tyrosine value and thio-barbituric acid (TBA) number did not show significant differences among the districts. The Siruvidai chicken of Tamil Nadu is meant for egg production and mothering ability. From this study, it is concluded that Siruvidai chicken may be utilized economically for meat production and processing.

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.

A four month old calf weighing 69 kg was attended at door step in the position of lateral recumbency with a history of anorexia, dyspnoea and voiding coffee coloured urine. Physical examination revealed subnormal temperature, pale mucous membrane, tachycardia with haemic murmur, tachypnoea and pounding femoral pulse. Examination of the blood smear revealed Babesia bigemina and complete blood count findings were reduced haematological parameters RBC–(1.5x10 6 ), PCV–(14%) and Hb–(3.5mg/dL). Based on the clinical and laboratory findings, the case was confirmed as Babesiosis and the calf was treated with Inj. Diminazene aceturate (Berenil) @ 3.5 mg/kg deep IM, Inj. Oxytetracycline @ 22 mg /kg IV and Inj. Ferritas 3 ml I/M on day 1. Subsequently on day 2 calf was transfused with two units (700 ml) of fresh whole blood as emergency treatment with dexamethasone @ 0.2 mg/kg BW IV, Avil 0.25 mg/kg IM. The calf was completely cured on day five and day 10 blood smear was negative for Babesia bigemina.

The present study was aimed to investigate the presence of Escherichia coli (E.coli) in raw chicken meat samples collected from retail shops, as well as the biofilm-forming ability of field isolates, and to characterize different adhesion genes. Out of 20 chicken meat samples, 17 (85%) were positive for E. coli. Fifteen E. coli strains were characterized by PCR using the 16S rDNA primers and all the isolates were positive which confirmed that all the isolates were E.coli. Out of the 15 confirmed E.coli field isolates which were subjected to biofilm-forming assay, 46% of them were found to be strong biofilm producers. While all the isolates were screened for the presence of adhesion genes viz. luxS, csgA, fimH, fimA, and papC, the adhesion gene luxS was detected in all the strains (100%). The other adhesion genes csgA, fimH and fimA were detected in 93%, 93%, and 73% of the isolates, respectively. The E. coli field isolates were screened blaTEM gene was detected in only four strains, which was categorized under strong biofilm producers. This study demonstrated the presence of biofilm forming E. coli in the raw chicken meat samples as contaminants, causing spoilage and potentially posing risk to consumer’s health and safety.

The present study aimed to investigate the effect of luteal regression on the conception rates in postpartum anestrus graded Murrah buffaloes. Ovsynch protocols: G48 group (n=10) and G56 (n=10) graded Murrah buffaloes, both received a 20 µg dose of GnRH on day 0, followed by 500 µg of PGF2α on day 7. On day 9, a final dose of 20 µg of GnRH was administered 48 hours after PGF2α for G48 and 56 hours after for G56. Fixed-time artificial insemination (FTAI) was conducted at 16-21 hours after 2nd injection in both groups. The luteal regression rates in both the groups were evaluated by progesterone hormone (P4) assay at different days of treatment. The results showed that in both groups, the concentration of P4 differed significantly (P<0.05) between and within groups at different days of treatment. In conclusion, it was found that the G56 group (70.00 per cent) had a higher overall conception rate than the G48 group (50.00 per cent) due to better luteal regression.

The brain samples were collected from 10 calves and 10 adult Indian buffaloes. Routine histological and histochemical processing and sectioning were done. The hippocampus was a curved elevation, lying immediately ventral to the splenium of the thalamus. Longitudinal section showed the ependyma, the alveus, the stratum oriens, the stratum pyramidale, the stratum radiatum, the stratum lacunosum and the stratum moleculare from above downwards. The prominent layer was the stratum pyramidale, composed of pyramidal cells in 2-3 rows. The four fields of the cornu ammonis, (CA1, CA2, CA3 and CA4) were identified based on the sizes of the pyramidal cells and their dendritic arborizations, both in the calf and in the adult. The presence of mucopolysaccharides was recorded.
