The investigation aimed to compare the effect of fresh and frozen-thawed X and Y fractions of flowcytometrically sorted bovine spermatozoa on in vitro fertilization of bovine in vitro matured oocytes and subsequent blastocyst development. Sperm cells sorted in MoFloSX cytometer were used either for IVF or frozen and stored in liquid nitrogen. Immature oocytes recovered from ovaries of slaughter...

Present study was planned to produce and evaluate liquid rennet from buffalo calves abomasa. Out of 30 abomasa collected, 20 samples were selected for the study and analyzed for proteolytic activity, clotting activity, productivity, shelf life, pH and sensory evaluation. Non protein nitrogen (NPN) contents of rennet coagulated milk (1.33±0.02%) were significantly higher (P<0.01) than that of ra...

We conducted a lactation trial with a fresh forage diet in order to evaluate 1) the effects of monensin on nitrogen metabolism, and 2) the Cornell Net Carbohydrate and Protein System (CNCPS). Thirty Holstein cows in midlactation (eight fitted with ruminal fistulas) were gradually introduced to a fresh forage diet. A concentrate mix based on corn meal was fed before the a.m. and p.m. milking tim...

Two experiments determined effects of collection and preparation techniques on nutrient composition of masticate samples from esophageally fistulated cattle. In Exp. 1, 12 esophageally fistulated cattle were maintained on 2 precollection diets, high CP (24% CP; = 6) or low CP (7.7% CP; = 6), for 8 d. On d 9, the esophageal plug was removed, screen bottom bags were attached, and each cow was off...

This research was conducted to determine the effects of chemical fertilizers, some organic and control applications on seed yield agricultural characteristics fresh beans in 2021. The trial carried out Faculty Agriculture University Selçuk more precisely application station Prof. Dr. Abdülkadir AKÇİN. In study, pure bean lines PV2001, Riberia, PV2002, PV2003 developed by hybridization were used...

The objective of the present study is to investigate the effects of irrigation water salinity,cow manure levels and different planting methods on ions variation in soil and their uptake bysaffron. A split-split plot arrangement was conducted in a randomized complete block designwith irrigation water salinity levels (0.45 (fresh water, S1), 1.0 (S2), 2.0 (S3) and 3.0 (S4) dS m-1)as the main plot...

A digital management system of cow diseases is presented in this paper, which based on standardization disease management framework. It can manage dairy cow disease from each stage including cow file creation, routine monitoring, disease prevention and control. Integrate electronic medical records was set up, which based on medical records include cow basic information and routine monitoring re...

In the study, 6 donors (n=6) cow of Selenge (n=3) and Alatau breeds were selected for superovulation. Superovulation treatment artificial insemination (AI) Donor Cow Regardless estrous cycle, Insert Controlled Internal Drug Release (CIDR; Hamilton, New Zealand) to from 5th day after inserting CIDR, diminishing inject Follicle Stimulating Hormone (FSH; Kyoritsu Seiyaku Corporation, Japan.) 36IU ...

Eight 4-ha mixed warm-season grass pastures in southwestern Arkansas (33°40'4″ N, 93°35'24″ W, and elevation 107 m) were stocked with either large mature size (571 kg [SD 55.2] BW) or small mature size (463 kg [SD 58.2] BW) spring-calving cows at 4 stocking rates (SR; 1, 1.5, 2, or 2.5 cow-calf pairs/ha) over 4 yr to test the effects of SR and mature body size on cow and calf performance and sy...

The objectives were to study the effects of feeding rolled flaxseed (FLX) to early-lactation dairy cows on milk yield, milk components, and milk fatty acid profiles as well as on measures of cow reproduction. Lactating Holstein cows, on 3 commercial dairies, were fed either an early-lactation ration (CON) or a ration that was similar in protein, energy, and fat content but that included FLX (0....
