Milk yield and economics

The genetic determinism of the calving and suckling performance of beef cows is little known whereas these maternal traits are of major economic importance in beef cattle production systems. This paper aims to identify QTL regions and candidate genes that affect maternal performance traits in the Blonde d’Aquitaine breed.

Endometritis is a prevalent uterine disease in postpartum cows. The disease reduces fertility performance and milk yield, and subsequently, productivity and profitability of dairy farms. The reduction in performance is associated with considerable economic losses on dairy farms.

The on farm trial was conducted during two consecutive years 2018-19 and 2019-20 at two adopted villages of Deendayal Research Institutes Krishi Vigyan Kendra, Ambajogai District Beed (Maharashtra). The trials were conducted for 60 days to study the effect of probiotics on milk yield and its production economics. The trials were laid out in a randomized block design consisting of three treatments with four replications of each.

Azolla is a free floating, rapidly growing aquatic fern on water surface. It is one of the most nutritive aquatic plants, owing to its high protein and carotenoid contents and of generally good amino acid profile. Traditional supplements based on oilseed cakes are expensive and cannot fulfill the required nutrients to animals. Forage-based economical feeding strategies are required to reduce production cost of quality livestock products. Productivity of dairy animals largely depends of efficient feeding management.

They form a symbiotic relationship with the cyanobacterium Anabaena azollae, which fixes atmospheric nitrogen, giving the plant access to this essential nutrient. Azolla has been used successfully as a protein supplement to replace meal in diets for livestock. According to Ambade et al., (2010), milk yield was increased by 15 to 20% after feeding azolla in the diet of dairy cows.

The demand of green fodder for livestock rearing has been increasing and livestock breeds of farmers require good quality fodder and feed in order to increase milk yield of exotic breed. The study was conducted in Kerala state of India and comprised of 242 farmers selected from three districts of the state. The impact of fodder cultivation was assessed on five levels viz. direct, social, economic, psychological and indirect impact. The study revealed that the highest percentage of farmers perceived fodder cultivation to have a medium level impact on their overall livelihood.

A study was conducted at the Banaras Hindu University Dairy Farm to estimate the effects of feeding management practices on rearing of animals and milk production in terms of economic analysis. The data pertaining to the feeds and feeding systems being followed and their input costs were collected from the records maintained for all the animals at the dairy farm. The lactation yield of cows and buffaloes has been worked out to 996 and 1150 Litres, respectively. The cost of daily feeding per head and per Litre of milk has been estimated to Rs. 60.26 and Rs. 10.80, respectively.

The present study was conducted at Livestock farm, Adhartal, College of Veterinary Science & A.H., N.D.V.S.U., Jabalpur (M.P.). A total of 12 advance pregnant Murrah buffaloes of identical parity and similar previous lactation yield were selected 21 days prepartum and randomly assigned to two groups of six animals each; CON as control with basal diet and MO as mustard oil supplementation @ 200 ml/animal/day upto 90 days post-partum to study the effect on economics of milk production in lactating Murrah buffaloes.

Buffaloes contribute a chunk to the total milk production in the Punjab state and have many advantages over cow milk and hence it is also known as black gold. The present study has been conducted in seven districts across three agro-climatic zones of the Punjab state to study the comparative economics of buffaloes and cow.

Sheep and goat brucellosis caused by Brucella melitensis, one of the most virulent Brucella species accounting for economic losses through abortion, stillbirths, reduction of milk yield and infertility. Disease has wide socioeconomic impact, in countries where, livestock sector is the major source of rural income. Early diagnosis is essential to minimise the spread of the disease besides public health importance. The present study reports the isolation, identification, biotyping and molecular confirmation of Brucella spp.

A lactation trial was conducted to study the effect of feeding sugarcane by products based complete ration on milk yield and milk quality as well, of murrah buffaloes. Seven rations (six complete rations were formulated by using sugarcane by-products and other crop residues and balanced concentrate mixture in the mash form and one conventional ration comprised with hybrid Napier and concentrate mixture) were prepared and fed 28 Murrah buffaloes distributed equally into seven groups in Randomized Block Design for a period of 180 days.

The present investigation was carried out to evaluate the economic loss due to subclinical and clinical mastitis in bovines. Data were collected from a primary field survey of the selected households by personally interviewing the household heads (100 farmers) with the help of a comprehensive and pre-tested questionnaire specifically designed for the study. Economic impact of mastitis was assessed by calculating production loss (milk yield loss and discarded milk) during mastitis, post treatment milk yield loss for 30 days and cost of treatment. There was a total economic loss of Rs.

Milk is known to carrier both pathogens as well as spoilage microorganism. This results in the economic loss of producers/processors/consumers and can pose a serious public health concern. Spoilage microorganisms group can degrade milk components, creating negative sensory attributes, decreasing processed product shelf life and adversely affecting fermented dairy product yield. Some microorganisms are beneficial and carrying out desirable fermentation in milk (prevent spoilage through fermentation).

The aim of present study was to find out the effect of „challenge feeding‟ on performance and economics of milk yield of crossbred cows. Eighteen advance pregnant crossbred cows were selected 60 days before expected date of calving and were divided into 3 groups i.e. control (T1), treatment (T2) and (T3) on the basis of milk yield, parity and body weight for this study. During the pre-partum period, animals of T1 control group were fed 1 kg concentrate for maintenance per day from 60th day to prior to calving till the day of parturition.

Mastitis is the most economically significant disease of dairy animals. This condition is associated with a significant reduction in milk yield, increased costs of production and deteriorated milk quality. In the present study a total number of 40 bovine mastitis milk samples were collected to isolate and identify the Pseudomonas aeruginosa. All the samples were inoculated into nutrient broth which was further cultured on agar plates. Colonies showing typical Pseudomonas morphological characteristics were processed for biochemical analysis.

Johne’s disease (Paratuberculosis), a debilitating chronic granulomatous enteritis of domesticated and wild ruminants that causes huge economic and production losses to the dairy farmers. A six-year-old Jersey crossbred cow was presented with a history of chronic diarrhoea, gradual weight loss, reduction in milk yield and poor response to therapy. Based on history, clinical examination, ZiehlNeelsen staining and IS900 polymerase chain reaction of the faeces the case was diagnosed as Johne’s disease.

Sub clinical mastitis is a hidden form of mastitis, causes a huge economical loss to the farmers. So, present study was done with the aim to find out such management practice to detect and control sub-clinical mastitis in the dairy cattle under field condition that can easily be adopted by the farmers. Eighty cattle having sub clinical mastitis were selected by Surf Field Mastitis Test (SFMT) and divided into two groups i.e., control (N=40) and treatment (N=40). Tri sodium citrate @ 30 mg/kg body wt. was supplemented to the cows orally till 10 days in the treatment group.
