Master Thesis

Indigenous poultry (Gallus domesticus) is one oldest domesticated bird contributing 55% of total poultry production in Nepal. The indigenous breeds of poultry of Nepal are Sakini, Ghanti Khuile (Naked Neck), and Puwakh Ulte. Sakini is the most adapted indigenous breed of Poultry of Nepal, covering more than 50%. At present, various kinds of literature including journals, research reports, annual reports, proceedings, and master thesis regarding the egg production performance of indigenous breeds were reviewed mainly aiming the comparative evaluation of indigenous breeds of chicken of Nepal with respect to the egg production performance. Egg weight (EW), Egg production per year, Clutch per year, Hatchability, and Age at first laying were the parameters compared. The egg production per year of Sakini and Ghanti Khuile was higher than that of Puwakh Ulte. Also, the hatchability of Sakini was significantly higher than that of Naked Neck. This was due to high feathers in Sakini as compared to Naked Neck. Sakini matures earlier than others and start laying earlier. However, there was not much difference in the egg weight of the indigenous breeds. The clutch per year and of Sakini and Ghanti Khuile was also not significantly different. Sakini starts laying eggs earlier than Ghanti Khuile and Puwakh Ulte. There is a need for increased researches in the indigenous breeds besides Sakini and diseases are major constraints reducing the returns to farmers. Government and concerned agencies should step up and help the farmers to maximize the returns.

Cocks and pullets from each of 4 genotypes; Redbro (RbRb), Naked neck (NaNa), Redbro dwarf (Rbdw) and Naked neck dwarf (Nadw) were crossed reciprocally for egg production trial. Egg quality (egg weight, egg diameter, egg length, shell thickness, membrane thickness, membrane weight, shell weight, % of shell, yolk color score, albumen diameter, albumen height, yolk diameter and yolk weight) were compared among 4 genotypes. Daily feed intakes, almost related to respected body size were reduced in Rbdw and Nadw hens by 7.41 and 19.89% than in normal sized RbRb hens. The feed conversion and hen day egg production were highest in Rbdw, intermediate in RbRb and Nadw and lowest in NaNa. Naked neck (Na) and dwarf genotypes had favorable effect on egg fertility and hatchability. Parents in both Na and dw inheritance had favorable shell thickness, shell membrane weight (%), albumen height and diameter, yolk height and diameter, albumen weight and albumen weight (%) and yolk weight, while NaNa had highest yolk weight (%). Both egg weight and chick weight percent were highest in RbRb x Rbdw genotypes, followed by RbRb, RbRb x Nadw, RbRb x NaNa, Rbdw x RbRb, Rbdw, Rbdw x Nadw, Rbdw x NaNa, Nadw x RbRb, Nadw x Rbdw, Nadw, Nadw x NaNa, NaNa x RbRb, NaNa x Rbdw, NaNa x Nadw and NaNa respectively. Chick weight as percent of egg weight irrespective of genotype was simply the functions of egg weight.DOI: http://dx.doi.org/10.3329/pa.v18i2.18167 Progress. Agric. 18(2): 115 - 121, 2007

This study was conducted to appraise the effects on egg quality and production performance of laying hens when drinking water was supplemented with calcium (Ca) and magnesium (Mg). A total of 384 (64-week-old) Hy-line Brown laying hens were assigned at random to four treatments, which consisted of CON: unsupplemented drinking water; T1: drinking water + 2 mg/L Ca + 250 mg/L Mg; T2: drinking water + 4 mg/L Ca + 510 mg/L Mg /10 L; and T3: drinking water + 5 mg/L Ca and 760 mg/L Mg. The experiment lasted six weeks. Water intake increased linearly in week 1 with the rising levels of Ca and Mg in the drinking water. Increasing the Ca and Mg levels improved eggshell strength (week 2 (P =0.01), week 5 (P =0.01), and week 6 (P = 0.03), and eggshell thickness (week 6) (P =0.02) and reduced the rate at which eggs were broken (week 4) (P =0.01). The supplemental Ca and Mg did not affect egg production, egg weight, Haugh unit, albumen height, eggshell colour, and yolk colour compared with CON. Nor did they influence the Haugh unit and albumen height after storing for 1, 5, 10 and 15 days. In conclusion, adding Ca and Mg to the drinking water increased the thickness and strength of the eggshells.

Present study was carried out to study egg production performance and polymorphism of Prolactin gene at 24 bp indel locus at promoter region (PRL24). Egg production performances were recorded as age at first egg (AFE), Body Weight at First Egg (WFE), Mean Egg Weight (MEW) and Total No. of Eggs at 90 days of laying (TEN). DNA was isolated from blood of 20 Kadaknath birds collected from wing vein. PRL24 locus for indel polymorphism was amplified by PCR and the product was resolved on 6% native PAGE for genotyping. The AFE (d), WFE (Kg), MEW (g) and TEN of Kadaknath hens in the present study were found to be 188.00±0.71, 1.26±0.03, 42.83±0.21 and 37.75±0.59 respectively. The Prolactin gene locus PRL24 showed two alleles I and D and three genotypes: II, ID and DD. The frequencies of I and D alleles at this locus were 0.55 & 0.45 respectively. The birds of D allele had a significantly (P<0.05) better TEN than birds of I allele.

The effects of the production system, breed cross, and their interaction on performance, egg quality, and hatching traits were evaluated. Rhode Island Red and Black Australorp were crossed with Naked Neck chickens (first generation RNN, and BNN, respectively). These crosses were mated among themselves and crossed to produce four crossbreds: RR (RNN x RNN), BB (BNN x BNN), RB (RNN x BNN), and BR (BNN x RNN). Thirty-six pullets and 9 cockerels from each crossbred were maintained in three production systems: the aviary system (AV), conventional cages (CC), and enriched cages (EC). Thus there were 48 pullets and 12 cockerels in each production system. Bodyweight, egg production percentage, and egg weight were highest in EC, followed by CC and AV. Higher egg weight, egg surface area, and egg volume were also observed in EC compared with CC and AV. Fertility and hatchability were higher and early embryonic mortality was lower in AV than in EC and CC. Bodyweight, egg production percentage, egg weight, egg volume, and surface area were higher for RB and BR than for BB and RR. Fertility and hatchability were similar for RB and BR. RR was similar to BR, but lower than RB. BB had the lowest fertility and hatchability. Thus, chickens in EC performed better than in the other systems, except that hatching traits were better in AV. RB and BR performed better than BB and RR.Key words: breed crosses, chicken, egg quality, hatchability

This study was conducted to know the production performance of laying hen by using different graded level of linseed. At 56 weeks of age, a total of 160 laying hens were raised up to 63 weeks of age. All hens were fed a basal corn soyabean meal diet. The experiment was allowed 4 dietary treatments (T0, no addition of whole linseed in the basal diet; T1,  addition of 5% whole linseed; T2, addition of 10% whole linseed and T3, addition of 15% whole linseed) with 5 replications and per replication contains eight hens. Egg production, feed intake, egg weight of each treatment was recorded. Egg samples were collected and analyzed for egg quality. The results showed that egg production and egg mass (kg) exhibited for all dietary treatment groups were unaffected (P>0.05) by feeding linseed to the laying hens. Feed Conversion Ratio (FCR) was found significant difference within the four dietary group (P<0.05). Egg quality aspects such as yolk weight, egg weight, HU and yolk index were not differed significantly (P>0.05) among treatments.  A trend for lower yolk weight was observed in birds fed 10% linseed, where as the highest yolk weight percentage was recorded in control diet. There was no statistical difference among the different diets for yolk index. The results of the present trial suggested that feeding linseed to the laying hens has no detrimental effects on egg production and egg quality.

Mineral Sources

Poultry production, health and wellbeing are highly dependent upon formulation of balanced rations in terms of energy, protein, and micronutrients (vitamins and minerals). Among all, minerals are required in fewer quantities, but they are very important to maintain the productivity in poultry. Minerals present in the feeds are less bioavailable and additional supplementation is obligatory to meet the physiological demands of poultry. Conventionally, minerals are supplemented as inorganic salts, which are less absorbed and, thus, a major proportion is excreted to the surroundings creating environment issues. Nano-minerals and organic mineral chelates are other alternative to be used as livestock and poultry feed supplements. Though organic minerals are more bioavailable than inorganic salts, their high cost limits its use. In contrast, nano-minerals are relatively easy to synthesize at a lower cost. Nano-minerals are of the size from 1–100 nm and due to such small size, there is an enormous increase in surface area and thus their biological responses. The biological response studies have signified better retention of nano-minerals as compared to inorganic salts, and consequently leached less to the environment preventing possible pollution. Apart from these, nano-minerals have been shown to enhance growth, egg production and quality, immune-modulation and antioxidant status, and at the same time economize the production by reducing the supplemental dose of minerals and improving the feed conversion ratio. Some nano-minerals and other nanoparticles have strong antimicrobial effects, which have been shown to reduce pathogenic microorganisms in the gut. Nano-minerals seem to be less toxic than conventional mineral sources. Though less, few studies have indicated toxic effects of nano-mineral supplementation at higher dose of application, which should be validated by more programmed studies. Nanotechnology in poultry production system is still in its budding stage and more detailed studies are warranted to validate, establish and search for new effects of nano-minerals as they sometimes produce effects beyond expectation. This review highlights the biological responses of nanominerals on poultry production performance, quality of meat and eggs, tissue retention, immunity, antioxidant activity and antimicrobial actions compared with their conventional mineral sources.

A survey was conducted in Batiaghata and Dacope upazilla of Khula district during the period from August to October, 2013 to observe the socioeconomic conditions of poultry farmers, existing feeding and management practices of poultry farms and performances of 5 different layer hybrids. The commercial layer hybrids considered in present study were of 30 layer farmers selected randomly from each Upazilla to collect the information. Data were collected using a pretested questionnaire by direct interview of the farmers. Collected data were analyzed using SPSS. To observe the socioeconomic conditions, the age of selected farmers, their occupation, education level, family size, land size and annual income were considered. Mean age at first lay did not vary significantly among 5 different hybrids. Average mature weights of layer birds varied significantly (P<0.001) among 5 hybrids. Average egg production percentage was highest in Hisex White (86.81±1.86) and lowest in Decalb White (59.75±14.81). Average egg weight (g/egg) was highest in ISA Brown (61.65±1.11) and lowest in Decalb White (52.58±4.21). Egg production percentages and egg weights varied significantly among 5 different hybrids. Mortality percentage did not vary significantly but feed consumption per birds per day varied significantly (P<0.05) among hybrids. Highest average feed consumption (g/bird/d) was observed in ISA Brown (113.18±1.94) and lowest in Decalb White (95.40±9.09). Correlation coefficient (r) indicates that egg weight increased with the increase of egg production. Among the five different commercial layer hybrids, Hisex White showed the best egg production performance and could be recommended for the farmers of Bangladesh.

Broiler parent stock of 7851 Cobb-500, 8388 Ross and 8745 Hubbard-Hi-Yield were reared in controlled (slated cum floor system) house to determine the egg production performance, fertility and hatchability. A total of 151200 hatching eggs of Cobb-500, Ross and Hubbard-Hi-Yield broiler strain were collected and set in the incubator in 10 batches having 15120 eggs in each batch and 5040 eggs in each strain to compare fertility and hatchability among the strains. From the above study, it was observed that the strains had significant effect (P<0.01) on egg production, fertility and hatchability of fertile, and set eggs, abnormal chicks, egg and chick weight but there was no significant effect (P>0.05) on normal chick production and chick weight as percentage of egg weight. Hubbard-Hi-Yield strain was the best while Ross was intermediate and Cobb-500 was the poorest in terms of egg production, fertility and hatchability. Therefore, Hubbard-Hi-Yield broiler parent stocks as well as its grand parent stock may be more profitable and suitable for broiler production in Bangladesh.

Medicinal Fungi

Application of different medicinal mushrooms intended to enhance production performance and health status has created an importance demand in poultry production. One goal of using medicinal mushrooms is to get rid of antibiotics in poultry feed without affecting the optimum performance. Increasing concerns about this issue have led to more attention on antibiotic substitutes and a significant demand for them for organic egg production. Thus, supplementation with medicinal mushrooms is a new concept for research in layer production, however, there is still a great deal of confusion about inclusion levels and the mode of action of medicinal mushrooms on production performance and health status in laying hens. Taking this into account, this review outlines the experimental uses of medicinal fungi on the growth performance, laying performance, egg quality, and health status of layer birds based on previous findings to date. Finally, we highlight that supplementation with medicinal fungi can play a role on the immunity, health, and production performance in laying hens.
