In this work, we introduce a method by which it is established that; how a sequence of non-primitive BCH codes can be obtained by a given primitive BCH code. For this, we rush to the out of routine assembling technique of BCH codes and use the structure of monoid rings instead of polynomial rings. Accordingly, it is gotten that there is a sequence $\{C_{b^{j}n}\}_{1\leq j\leq m}$, where $b^{j}n$ is the length of $C_{b^{j}n}$, of non-primitive binary BCH codes against a given binary BCH code $C_{n}$ of length $n$. Matlab based simulated algorithms for encoding and decoding for these type of codes are introduced. Matlab provides built in routines for construction of a primitive BCH code, but impose several constraints, like degree $s$ of primitive irreducible polynomial  should be less than $16$. This work focuses on non-primitive irreducible polynomials having degree $bs$, which go far more than 16.

The objective of the present study was to observe the circulating metabolic, reproductive, and stress hormones in laying hen performance under different heat-combating systems (HCSs). A total of 500 White Leghorn pullets at 24 weeks of age were subjected to four HCSs, i.e. desert cooling (DC), water sprinkling (WS), time limit feeding (TLF), and ascorbic acid (AA) supplementation, at environmental temperatures from 32.30 to 40.80 °C with 76.40% relative humidity. Blood was collected before heat stress, at peak stress, and after heat stress to collect plasma. The results of the 24-week stress period showed significantly less circulating T 3 , T 4 , estrogen, and progesterone in the control group in the peak stress period, whereas corticosterone was significantly higher. The plasma T 3 , T 4 , and estrogen and the egg production percentage remained significantly higher in the DC system as compared to other HCSs and the control. In comparison, the plasma progesterone level was significantly increased with lower T 4 in the AA supplementation group than the other HCSs. Our results validate the potential role of the DC system in protecting birds from environmental heat stress effects and subsequent improvement in egg production.

Bovine milk, a rich source of proteins and fatty acids, has a beneficial impact on physicochemical and organoleptic properties. The current study was planned to identify oxytocin's effects on protein and fatty acid profiles of cow milk (the Sahiwal breed) at various lactation stages (early, middle, and late) under a controlled atmosphere and feeding inputs. Examination of milk protein and fatty acid profiles by urea polyacrylamide gel electrophoresis and gas chromatography-mass spectrometry respectively revealed the significant effect (P < 0.01) of oxytocin during the cow's lactation stages. In electrophoretic patterns, casein (αs1-CN, αs2-CN, β-CN, and k-CN) and whey protein fractions (Ig, BSA, β-Lg, and α-La) appeared as low-intensity bands in oxytocin-injected milk when compared to the control. Reductions in concentrations of fatty acids C16:0 (25.00%) and C18:1 (21.60%) were observed in oxytocin-treated milk as compared to the control group (29.30% and 29.10%, respectively) at late lactation.
