: Staphylococcus aureus is the key causative agent for contagious mastitis and responsible for subclinical infections leading to economic loss to dairy industry worldwide. Hence, the present work was planned to isolate and characterize the Staphylococcus aureus from bovine mastitis cases of S. aureus origin. From non therapeutic areas, a total of 381 staphylococcal isolates were recovered out of 438 milk samples with percentage positivity of 86.98, whereas, out of 60 milk samples in selected therapeutic areas 40 staphylococcal isolates with positivity of 66.67% were recovered based on cultural and biochemical tests. A total of 290 out of 381 and 30 out of 40 culturally positive isolates respectively from non therapeutic and therapeutic areas were confirmed as S . aureus by PCR method targeting the 16S rRNA with an expected amplicon size of 229bp. Sequencing and nucleotide analysis of 16S rRNA amplicons of non therapeutic area isolates showed 99.3% identity whereas therapeutic isolates showed 95-100% identity with gene bank reference strains. On phylogenetic analysis, isolates form non therapeutic area were not closely related to reference gene bank strains whereas isolates of therapeutic area were shown close evolutionary relationship with gene bank reference strains. Further, Peruru isolates of therapeutic area have shown close evolutionary relationship with Spain isolate KX348312.1 and formed separate group in cladogram.

: The present investigation included the records of 294 Kankrej cows, sired by 66 sires spread over a period of 20 years (1996 to 2015) maintained at Livestock Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat. The effects of genetic and non genetic factors on performance traits (Daily Milk Yield, 305 Days Milk Yield, Total Milk Yield and Lactation Length) of primiparous Kankrej cows was studied. The least square means of daily milk yield, 305 days milk yield, total milk yield and lactation length were calculated and found 6.71±0.14, 1893.42±60.00, 1983.29±72.47 kg and 290.78±7.33 days, respectively. The season and period of calving did not affect these traits, while effects of sire was significant (*P<0.05) on 305 DMY, but it did not have any effect on the traits such as DMY, TMY and LL of primiparous Kankrej cow. On the basis of these observations, we can suggest that proper management practices as well as use of better sire will help to improve the production performance of the herd.

: The objective of present study was to evaluate the effects of chemical additives on the quality parameters and nutritive value of sugarcane tops (SCT) silages. The trial was carried out in a completely randomized experimental design with total twelve treatments including two controls, C1 (without additive) and C2 (with common additives viz., 0.5% Urea, 0.5% NaCl and 2% molasses on wet basis). However, ten treatments (C2+ other chemical additives viz., SB; Soidum benzoate, PS; Potassium sorbate, PA; propionic acid and their combinations) were applied @ 0.1% (wet basis) onto the fresh SCT and ensiled for 30 days in 3.5 L vacuum sealed plastic jars in two replicates of each treatment. The analyzed variables were: chemical composition, quality parameters and nutritive values. Selection of most promising additive/combination was done with Flieg point and fitness values. The addition of chemical additive before ensiling produced silages with better quality indices (pH, lactic acid, Flieg point and fitness values), higher nutritive value (crude protein and ME) and low NDF as compared to control with additive (C2). Ammonia Nitrogen (NH 3 N% TN) and protein fractionation (NDICP and ADICP) were also considered for the identification of best SCT top silage and chemical additive effect. The results of present study indicate that PA and PS+PA were the most promising additive treatments for the improving the SCT silage quality and nutritive value. Furthermore, information extended from the present study is giving future direction towards animal feeding trials with SCT silage with chemical additive.

: The paper aims at micro-level evaluation of dairy centric socio-technological interventions under the Technology Demonstration Component (TDC) of the National Innovations in Climate Resilient Agriculture (NICRA) Project in Karnal, Yamunanagar and Sirsa districts of Haryana. The interventions were introduced to address the identified climate stresses under the project for enhancing resilience in dairy production. The study was conducted during 2015-16, employing Participatory Rural Appraisal (PRA) techniques to assess the farmers’ feedback on climate change perception and their acceptance and satisfaction of introduced interventions, from the NICRA adopted village in each district. Ten socio-technological interventions were evaluated each based on two dimensions of perceived attributes and benefits sub-evaluation parameters. The reason based satisfaction was recorded on a farmer rating for each intervention. Among six introduced technological interventions, improved fodder crop varieties (total score 28 and 30) and area specific mineral mixture supplementation (total score 28 to 29) were perceived as highly beneficial in terms of sustained milk production even during periods of heat stress followed by moderate beneficial of interventions viz ., Vitamin E supplementation, mustard oil supplementation and safe dung disposal through composting. Silage making intervention was perceived as low beneficial (total score 16). The Village Climate Risk Management Committee (VCRMC) was found as a highly beneficial (total score 27 to 30) social intervention, followed by women participation, contingency plan for climate change preparedness in fodder crops and preparation of season-centric milk products as moderate beneficial. The VCRMC was found highest satisfactory as rated by the farmers.

: The experiment was conducted to study the effect of optimized preservative formulation (combination of bronopol TM and kathon TM ) on compositional and physico-chemical parameters of milk. The optimized formulation was added at the rate of 0.6% in milk samples and effect was observed on estimation of fat, protein, lactose and ash content during storage at 37 o C. For comparison, the legally permitted preservative (by Food Safety and Standard Authority of India, 2011) formalin was also added at the rate of 0.4% in milk samples. There was no significant effect of optimized formulation on estimation of fat and lactose content for 45 days and total solid (TS), ash and protein content for 90 days. However, on addition of formalin, the fat and lactose values of milk decreased after 15 days of storage and no significant effect was observed on TS, ash, protein content for 90 days and lactose content for 60 days.

Prolonged oestrus is one of the conditions associated with perturbed follicular dynamics that culminates into substantial economic losses to dairy industries through low success rate of artificial insemination, increased inter-calving period, reducing total milk yield, lowering calf production, shortening reproductive life of the animals, lowering fertilisation rate and abnormal embryonic development. Prolonged oestrus is characterized by the exhibition of extended duration of oestrus in various breeds of cattle. Cows having prolonged oestrus need to be examined at frequent intervals for determining the correct time of artificial insemination. This makes it challenging to inseminate the animals at the correct time, which is a major inconvenience for the field veterinarians and farmers. Since the follicular dynamics in cows is intricate to comprehend, the disorders in which also often go unnoticed and not treated/managed wisely in the field conditions. Therefore, it is of paramount importance to understand the aetiology of prolonged oestrus so that strategies to improve fertility could be designed. Alterations in hypothalamohypophyseal-gonadal axis, which is also influenced by some other extrinsic factors like stress, nutrition, age, parity, breed etc., apart from the endocrine alterations could cause the prolonged dominance of follicle. The presence of suprabasal progesterone and luteal insufficiency are considered as the main cause of this condition among cattle. In this review, we attempted to analyse the prior art on the topic and to delineate the possible causes, and to suggest managemental strategies to mitigate the prolonged oestrus condition in dairy cows

: Desi cows along with crossbred have major contribution in fulfilling the demand of milk by the growing population of India. Achieving food security, nutrition security and income security for the farmers and by the farmers is a priority concern of national and state governments in India. In order to fulfill the national goal of doubling farmers income by 2022, animal husbandry in general and dairy farming in particular are considered as potential activities. In this backdrop, the present study was carried out in six districts of Karnataka based on higher population of desi cows with a sample size of 240 farm households. The study revealed that the sample households had more number of milking desi cows as compared to crossbred cows. Average quantity of green fodder and concentrates fed per animal in case of desi cows was less compared to crossbred cows. Thus, total feed cost and expenditure per animal was less in case of desi cows than crossbred cows. Desi cows required less expenditure on health per day/anim., but the net return per animal, per farm and per liter was less in desi cows due to low productivity as compared to crossbred cows. Crossbred cows supplied more nutrients to farm i.e. NPK kg/year/animal compared to desi cows. However, protein, fat and calcium nourishment per animal to the family was more in case of desi cows as compared to crossbred cows. Employment generation (mandays/year) per animal was more in case of crossbred cows as compared to indigenous cows. Security for uncertainties and status symbol was more in case of crossbred cows as compared to desi cows.
