he present investigation was conducted to study the effect of various non genetic factors like farm, parity, period of calving and season of calving on different production traits like total lactation milk yield (TLMY), 305 day milk yield (305MY), peak yield (PY), milk yield per day of lactation length (MY/LL) and milk yield per day of calving interval (MY/CI) in Murrah buffaloes. The data analysed include records of 2959 buffaloes, progeny of 219 sires maintained over a period of 24 years (1992-2015) at Buffalo research centre (BRC), LUVAS, Hisar and Animal farm ICAR-CIRB, Hisar.

The objective of the study was to assess the effects of non-genetic factors such as farm, order of ejaculate, period, season of collection and age of the bull on semen quality traits of crossbred Holstein Friesian (CBHF) bulls. Data on a total of 22442 ejaculates from 72 CBHF bulls collected during the period from 1996 to 2014 were obtained from three organized farms in Tamil Nadu, India.

Data on 106197 semen ejaculates of 310 crossbred Jersey bulls maintained at three frozen semen stations in Tamil Nadu, India were collected from the year 2002 to 2014. The effects of various non-genetic factors such as farm, ejaculate number, period of semen collection, season of semen collection and age of the bulls at collection were studied on semen quality parameters using least-squares method.

A total of 1649milk samples from 172 Gir cows of Cattle Breeding Farm, Junagadh Agricultural University were collected with fortnight interval throughout the lactation for a period from 04-04-2014 to 10-10 -2015. The samples collected were analyzed for estimation of Fat %, SNF %, and Protein % and Sugar (Lactose). Total period was grouped in four seasons: Rainy, Winter, Spring and Summer. Total 11 stages were considered to for analysis. Effect of lactation order was considered as cows in lactation order from 01 to 10 parity were included in the study.

Data pertaining to 519 Sonadi sheep maintained at Mega Sheep Seed Project (Sonadi Unit) College of Veterinary Science, Navania, Vallabhnagar (Rajasthan) were analyzed to assess the effect of non-genetic factors (sex, season and period of lambing ) on growth traits viz. birth weight (BWT), three (3WT), six (6WT), nine (9WT) and twelve (12WT) months weights. The estimated least squares means for BWT, 3WT, 6WT, 9WT and 12WT were found as 3.07±0.03 kg, 11.32±0.30 kg, 15.94±0.56 kg, 19.12±0.53 kg, 22.73±0.56 kg, respectively. Sex of lambing had significant influence on all growth traits.
