Variable milk yield

Milk yield for Holstein cows has doubled over five decades due to genetic selection and changes to management, but the molecular mechanisms that facilitated this increase are mostly unknown. Epigenetic modifications to the cattle genome are a plausible molecular mechanism to cause variation in milk yield and our objective was to describe genome-wide DNA methylation patterns in peripheral blood mononuclear cells (PBMC) from mature Holstein dairy cows with variable milk yield.

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.

Monthly data of 4 cows of Jersey and 4 cows of Holstein Friesian crossbred cows on milk yield of seven lactations and for different months were analyzed for the present study which were collected from Dairy Farm of Dr. Yashwant Singh Parmar University of Horticulture and Forestry NauniSolan, Himachal Pradesh. Different variability parameters were estimated separately for both cross breeds and also the stability analysis was carried out to study the performance of different lactations and months with respect to milk yield.

Protein-lipid film is a very popular food material which can be prepared from various protein foods. A remarkable example of the protein-lipid film is a traditional soybean food which is a cream-yellow bland flavoured surface film of high nutritional value (soy protein-lipid film, designated as Yuba or soymilk skin), which is formed during the heating of soymilk. The protein digestion rate of the protein-lipid film is almost 100%.

HF × Gir cattle, Genetic parameter, First lactation traits The present investigation was carried out with the objective of performance appraisal of HF × Gir cattle with respect to production and reproduction traits. The performance records of 421 HF × Gir half breed cattle sired by 48 bulls were collected for production and reproduction traits spread over a period of 39 years (1977 to 2015) from ResearchCum Development Project on Cattle, Mahatma Phule Krishi Vidyapeeth, Rahuri District Ahmednagar (Maharashtra).
