To improve reproductive performance in cattle, the accurate detection of estrus and optimization of insemination relative to ovulation are necessary. However, poor heat detection by farm staff leads to a decreased conception rate, thus inflicting economic damage to the beef and dairy industries. This study aimed to develop monoclonal antibodies (mAb) that can specifically bind to the bovine lactoferrin (bLF) protein, which we have previously demonstrated to be overexpressed in bovine cervical mucus during estrus. Female rats were intraperitoneally immunized with bLF protein as the antigen. Anti-bLF mAbs were then purified by affinity chromatography, and their binding affinity for the bLF antigen was examined using ELISA. We found a high binding affinity between mAbs and bLF. Finally, we developed a rapid bovine heat detection kit using the anti-bLF mAbs that we generated and tested on cervical mucus from 12 cows (estrous synchronization, n = 2; natural cycling, n = 10). We found that the kits accurately detected estrus. Overall, our fabricated heat detection kit based on rat anti-bLF mAbs could pave the way for the development of potent tools for heat detection devices for dairy cattle, thereby preventing economic loss.

Ecosystem State

In the pursuit of identify ways for a better understanding the barriers of the dairy production system, we sought to diagnose them from the perspective of the business ecosystem concept, through a systematic literature review. Thus, we use content analysis to serve as the basis for analysis and discussion of the barriers of dairy production. Resulting a total of fifteen barriers, properly presented and discussed. In addition, we provide some insights to mitigate these barriers. The study presents contribution to the development of dairy production by providing assistance to develop strategies for producers’ cooperatives, government agencies, milk producers, hulling industries products from milk. Based on the perspective of the business ecosystem is possible to have a broader view of the scenario where dairy production occurs and recognize the barriers of dairy production system. And once identified these barriers, it is possible to devise strategies to eliminate or mitigate these barriers.

The aims of this study were to evaluate the traits of reproductive, milking and growth performance of Saanen and Saanen × Hair crossbreds (F1, B1 and B2) raised at the Bandırma Sheep Research Institute. The data were collected from 868 goats for reproductive performance and milk yield and from 1077 kids for survival performance between 2009-2012. Milk components (fat, protein, lactose and non-fat dry matter) of goats (n=162) and body weight changes of kid’s (n=64) were evaluated for one year in 2012. Estrus rates and survival rates were similar among all genotypes. Kidding rate was significantly higher in F1 goats than Saanen goats. Saanen goat had the lowest average mean daily milk yield compared with other genotypes. The effect of year and age were significant on milk yield. Goats in F1 and B1 genotypes had higher milk protein percentage and non-fat dry matter content in comparison with Saanen and B2 genotype. Milk fat and lactose contents were similar among genotypes. Birth weight and monthly live weight were similar between genotypes while weaning weight, six month live weight and yearling live weight were higher in B1 kids in comparison with Saanen kids. The effect of dam age and birth type were significant on birth weight, monthly live weight and weaning weight. The findings related to performance characteristics in goat genotypes investigated show that B1 genotype could be recommend for semi-intensive production system in the Western Anatolia.

The World

The epidemic crises place massive burdens on our economies. The risk of food supplies is also pushing massive stress on food vendors around the world. There are big problems associated with supply chains framework. Farmers do not receive payment upon delivery of their supplies. The buyers do not have access to finance that will enable them to pay farmers on time. To solve this problem, the authors proposed a dairy production system integration with blockchain and IoT. Blockchain is a decentralized digital ledger technology that allows network participants to trust each other and interact. The dairy product system can check the temperature of the product in real-time by using the website application. Moreover, customers can get notifications when the policy found problems related to temperature values. The blockchain database confirms the information security of the system by using the proof of work algorithm to create the transactions and the blocks. Therefore, the proposed methods can use sensitive data with reasonable time consumption, and no block creation fees are needed.

Are we ready for the big change in the dairy production system?
