Influence of photoperiod and light intensity on Bambusicola thoracicus was studied, whereby One Hundred birds were distributed into 5 treatment groups viz. A1, A2, B1, B2 and C. The birds in group A1 were treated with light intensity of 80 luxes/8 hours during growing period and 240 luxes/16 hours during laying period, group A2 with light intensity 20 luxes/8 hours during growing period and 60 luxes/16 hours during laying period. Birds in group B1 were provided photoperiod of 5 luxes/16 hours during growing and 15 luxes/20 hours during laying period, while in group B2 photoperiod of 5 luxes/12 hours during growing and 15 luxes/18 hours during laying period was provided. Group C was kept as control group. Results indicated average body weight of group A1, A2, B1, B2 and C, 196.25; 192.24; 186.98; 190.00 and 190.44g/b respectively, feed intake 202.13; 211.98; 230.11; 212.25 and 207.11g/b respectively. The FCR was recorded best in group A1, while carcass weight (99.57g), dressing percentage (52.02%) and egg length (33.11mm) was found higher in group A2. Average egg production percent was higher in group B1 (70.24), egg width in A1 (24.89) respectively. Study concludes that the Bambusicola thoracicus reared under 80 luxes light intensity for 8hrs per day during growing period and 240 luxes light intensity for 16hrs per day in laying period showed better FCR and feed intake, however egg production was observed better when birds were provided 5 luxes for 16hrs photoperiod during growing and 15 luxes for 20hrs photoperiod during laying period.

The aim of this trial was to study the effects of consuming water with apple cider vinegar (ACV) and feed including mushroom (Agaricus bisporus) stalk (MS) on performance and certain egg characteristics. The hens were separated into four treatment groups (with 4 replicates and 6 hens per replicate). The experimental groups were control (not consumed ACV and MS), ACV (3 ml/l drinking water), MS (20 g/kg feed) and ACV+MS (combination). At the end of the experiment, among the performance criteria tested, body weight, feed intake, egg production and weight of eggs, and feed efficiency were not affected by the treatments (P>0.05). Treatments had no effect on physical external and internal egg characteristics. The amount of yolk malondialdehyde of the ACV and MS groups was lower than the control group (P Less then 0.05) in stored eggs (28 d) (P Less then 0.05).

The paper explores the impact of monochromatic illumination on replacement chickens of Decalb White cross-breed in the conditions of the Amur region. The chickens were grown from 1 day to 115 days age. The research was conducted in the conditions of the poultry farm “Belogorskaya”. The authors arranged four groups according to the principle of steam-analogues; each group contained 200 chickens and the experiment was carried out in the production unit. The researchers used luminous tube lamp with different colour temperatures for lighting. White lighting was used in the control group, yellow - in the first experimental group, green - in the second experimental group and blue - in the third experimental group. The researchers made blood test of chickens aged 30, 60 and 90 days for morphological and biochemical analysis. The authors carried out control weighing of the poultry at that time. At the end of the experiment, three pullets from each group were slaughtered in order to study the organs. The paper highlights morphological and biochemical blood parameters of replacement chickens at the white light had lower deviations from the physiological rate than at yellow, green and blue lamps. At the beginning of growing under yellow lamps, the concentration of gamma-globulin fraction of protein in the blood serum of chickens was higher than the age rate and the content of albumins was lower. Compared to the control group, the amount of bilirubin (P<0.05) and the activity level of asparagine aminotransferase (P<0.001) were higher under green and blue lamps. In the middle and at the end of the growing period, the number of leukocytes, creatinine, uric acid and asparagine aminotransferase may have increased in chickens under green and blue light. The difference among the results of blood tests of chickens grown under white light was, mostly reliable. When controlling the growth and development of replacement chickens aged 30 and 60 days the authors observed that the average body weight of chickens in white light was 1.5-3.9% higher than in the poultry of experimental groups. The average body weight of the chickens aged 90 days from all the groups was at the same level. The results of the control slaughter of pullets aged 115-days and grown under different lighting conditions were similar, and their sexual maturity was the same.

To know the production performances of different commercial layer strains in Bangladesh, total 18,420 birds of ISA Brown, 14,790 birds of Novogen-Brown and 27,400 birds of Shavar-579 Brown were studied from 30 commercial layer farms (10 farms for each strain), which were randomly selected from the 7 different districts of Bangladesh by farm visit via a well structured questionnaire. All birds were reared in open-sided shed in cage system. The hen day egg production percentage (HDEP%), average body weight and average feed intake per day of three different strains were studied. The HDEP% of ISA Brown, Novogen-Brown and Shaver-579 Brown were 90.79±0.44%, 78.89±1.84% and 79.13±1.41% respectively, average body weight were 1877±26.4 gm, 1885±26.9 gm and 1815.5±43.9 gm respectively, average feed intake per day were 111±1.88 gm, 109.8±1.86 gm and 112.5±1.35 gm respectively. The HDEP% was higher in ISA Brown, however there were no significant difference among strains for average body weight and average feed intake per day. Finally, it is recommended that ISA Brown is more adaptable and profitable in Bangladesh than that of other strains. Further scientific study is needed to see the production performance of different commercial layer strains in farm trail with same environmental condition. Asian J. Med. Biol. Res.

The current experiment was designed to investigate the effect of zeranol implantation on lambs and goats’ kids raised under commercial conditions. Ten male Awassi lambs (AL) (4-5 months old) with an average body weight of 33.7 ± 0.5 kg and 10 male black goat kids (GK) (3-4 months old) with an average body weight of 18.8 ± 0.7 kg were used in the experiment. The experiment was conducted in Berebuhar village close to Duhok city in May the 15th, 2019The animals from each group were randomly divided into two subgroups, the first group was the control group and the other group was implanted with 24 mg zeranol. The animals were grown for 43 days and then slaughtered. Growth rate, average daily gain and carcass characteristics were measured. Data were analysed as factorial 2 × 2.  The results showed that implantation both animal groups with zeranol significantly reduced testicular weight by approximately 55 % and 71 % for goat kids and Awassi lambs respectively. Moreover, the results showed that zeranol implantation found to reduce total body fat from 892 to 816g in goat kids and from 3395 to 2856 g in Awassi lambs. It can be concluded that zeranol implantation has an effect on total body fat and fat tissue distribution.

Purpose. Evaluate the effect of metabolic control of gestational diabetes mellitus (GDM) on the perinatal period course and anthropometric parameters of newborns.Materials and methods. 300 newborns were divided into 4 groups depending on the metabolic control of the mother. Group 1: fasting glycemia <5.1 mmol/L, 1 hour after meals <7.0 mmol/L (n = 50); Group 2: <5.3 mmol/L and <7.8 mmol/L (n = 90); Group 3: > 5.3 mmol/L and> 7.8 mmol/L (n = 46), respectively; Group 4: control (n = 114). The analysis of the perinatal period course was carried out, the anthropometric parameters were estimated according to the tables INTERGROWTH-21st.Results. Differences in the frequency of obstetric injuries, which risk is associated with «above average» body weight of the newborn (p = 0.04), were found between the GDM group and the control group (38.7 and 12.3%, respectively, p = 0.0000005). The risk of having a baby with «above average» body weight (Group 1/Group 4, OR = 1.9, p = 0.1; Gr. 2/Gr. 4, OR = 2.6, and Gr. 3/Gr. 4, OR = 3.7, p <0.05), the ratio of weight/length (Gr. 1/Gr. 4, OR = 0.9, p = 0.9; Gr. 2/Gr. 4, OR = 3.6, and Gr. 3/Gr. 4, OR = 4.9, p <0.05) and head circumference (G.1/Gr. 4, OR = 1.1, p = 0.6; Gr. 2/Gr. 4, OR = 2.5, and Gr. 3/Gr. 4, OR = 2.9, p <0.05) was higher in Groups 2 and 3 than in Group 4. In the early neonatal period with GDM, hypoglycemia was more common than in the control Group 4. The lowest risk was in Group 1 (Gr. 1/Gr. 4, OR = 4.8; Gr. 2/Gr. 4, OR = 6.7; Gr. 3/Gr. 4, OR = 7.9, р < 0,05).Conclusions. Group 1 showed the lowest frequency and risk of adverse effects, which meets the control criteria of the Russian consensus.

The objective of this study was to evaluate the effect of sex class (castrated; non-castrated) and level of food restriction (0%, 30% and 60% of ad libitum consumption) on the quantitative composition of carcass and non-carcass components of Santa Ines lambs. A completely randomized 3x2 design (restriction level x sex class) was used to evaluate thirty lambs approximately two months of age with an average initial body weight of 13 ± 1.49 kg. When the average body weight of the animals in one of the treatment groups reached 28 kg, all animals were slaughtered. Sex class had effect on body weight at slaughter, empty body weight, hot carcass weight and cold carcass weight. The weight of the leg was greater in non-castrated animals. There was linear decreased effect according to increasing levels of restriction for the carcass cuts, except for leg and rear loin yield. There was statistic difference between sex class for the weights of kidneys, paw, and large intestine of non-castrated animals (P < 0.05). There was a negative linear association between level of food restriction and mass of blood, head, leather, paw, rumen, reticulum, abomasum, small intestine, large intestine; perirenal, omental, mesenteric and heart fat. The quantitative composition of carcass and non-carcass components of Santa Ines lambs is influenced by sex class and food restriction level.

The study was conducted at Bangladesh Livestock Research Institute to evaluate the productive and reproductive performances of 4 pure lines conserving for the production of next generation. A total of 2000 pedigree hatched day-old chicks were wing banded and reared up to 40 weeks of age. Data were kept on daily feed intake (g/bird/day), weekly body weight (g), age at sexual maturity (days), daily egg production (%) and egg weight (g). There were highly significant differences (p<0.01) in body weight at 38 weeks, age at sexual maturity, egg production up to 40 weeks and egg weight at 38 weeks of age among the treatment groups. There were no significant differences (P>0.05) in fertility, hatchability, dead in germ, sound chick and dead in shell percentage among the treatment except cull chicks where L1 showed the highest percent of cull chicks.  Egg production at 23-28 and 35-40 weeks of age differ significantly (p<0.01) except at 29-34 weeks of age (p>0.05). Significant variations for FCR observed at 35-40 weeks of age while it was non-significant (p>0.05) at 23-28 and 29-34 weeks of age. It is revealed that line-2 is superior in terms of egg production, age at sexual maturity and egg mass where line-1 was better in terms of FCR value. Considering the results it may be concluded that there are significant variations exists regarding egg production performances among the experimental pure lines, thus could be utilized successfully for the production of high yielding strains through proper breeding programme.

The aim of the present study was to assess the effects of a prolonged photoperiod on growth rate and sexual maturation in brook trout Salvelinus fontinalis. The task of the experiment was to determine the most effective light regimen capable to minimizing the effects of puberty, including impairment of somatic growth and further general characteristics. In this regard, the studied fish were reared under three photoperiod regimens in which fish were exposed to 24 h continuous light alternating with 24 or 48 h under the ambient photoperiod or 48 h continuous light alternating with a 24 h ambient photoperiod. A control group was reared under the natural ambient photoperiod. Four-hundred and fifty fish with an average initial body weight of 101.3 ± 1.2 g were used for each experimental group (three replicates of each treatment plus control). A statistically lower growth rate showed control groups in both sexes. At the end of the study, control males had an average body weight of 226.6 ± 39.8 g and control females a body weight of 199.8 ± 12.2 g. At the same period, a significantly higher average body weight was found in groups reared 24 h under ambient photoperiod alternating with a 48 h continuous light regime (2CP:1AP) in both sexes (296.56 ± 62.5 g—males, and 239.9 ± 19.2 g—females, respectively). A significantly higher percentage of sexually mature fish was observed in the control group (80% of males and 29% of females, respectively). We found significantly fewer sexually mature females compared to males. The lowest survival was observed in group 2CP:1AP at 92%. It was concluded that regimen under which fish was exposed to 48 h of natural ambient photoperiod alternating with 24 h of constant light (1CP:2AP) lead to the successful delay of gonad development and onset of puberty and increased somatic growth in both sexes.

 Four dietary treatments differing in protein levels were compared to ascertain the protein requirement of laying Japanese quail in a semi-arid environment. One hundred and twenty quails were randomly assigned to four treatments (TI — 22%CR T2 — 20%CP T3 — 18%CP and T4 - I6%CP) in a completely randomized block design Each treatment was replicated thrice with ten quails each. Feed intake, body weight gain, hen day egg production, feed conversion ratio FCR), egg quality and hematological constituents were the response criteria. The study lasted seven weeks. Feed and water were provided ad libitum throughout the experimental period No significant (P> 0.05) effect of dietary protein was observed for feed intake, average body weight gain, hen-day egg production, F CR, dressing percentage and hematological parameters. Average body weight was significantly (P<0,05) enhanced by high dietary protein. Egg weight and Haugh unit were significantly (P<0. 05) better for the groups fed the higher protein levels (20 and 22% CP). Hen-day egg production, albumen index, specific gravity, shell weight and percent shell were not affected (P>0.05) by dietary protein levels. The costs of producing l kg egg in the treatment groups were ₦25926, ₦21007, ₦252.44 and ₦1263./10 for T1, T2, T3 and T4, respectively. It was concluded that about 20%CP is required in the diets of laying Japanese quail under a semi-arid environment of Nigeria.
