This study was conducted to investigate the effects of cage stocking density on egg yield, some egg quality traits and plumage condition in laying hens. Eighteen weeks-old 264 ISA-Brown pullets were divided into four cage density groups. The densities were 2 000, 1 000, 667 and 500 cm<sup>2</sup> per hen (by allocating 1, 2, 3 and 4 hens per cage; floor area 40 × 50 cm) with 48, 30, 24 and 21 replicate cages, totally 123 three-tier battery cages. During the experimental period from 18 to 53 weeks of age, all birds were provided illumination for 16 hours a day. The hens were fed a diet containing 11.7 MJ ME/kg and 180 g CP during the period of 18 to 40 weeks of age and 11.3 MJ ME/kg and 170 g CP during the period of 41 to 54 weeks of age. Feed and water were available for <I>ad libitum</I>. Egg yield, mortality, live weights at 50% egg production age and at the end of experiment, pecking related mortalities, some egg quality traits and plumage condition were recorded weekly. Hen-housed egg production, egg mass, viability, and live weights were significantly decreased by higher densities. Most of the egg quality traits were not affected by cage densities. Pecking related mortalities increased in cage densities of 667 cm<sup>2</sup> and 500 cm<sup>2</sup> per hen compared to the other densities (<I>P</I> < 0.05) while plumage scores were higher in all body parts of hens kept in cages of 2 000 cm<sup>2</sup> and 1 000 cm<sup>2</sup> densities compared to the higher densities. The results showed that brown laying hens should be kept in cages having 1 000–2 000 cm<sup>2</sup> densities in order to improve their welfare and performance.

Two trials were conducted to study the effect of feeding barley silage on the behaviour and performance of beak-trimmed laying hens. In each trial, 20 hens and 2 roosters were housed in each of eight group-housed enriched cages, with four cages provided a laying hen diet and four cages additionally given free access to barley silage. Egg production and quality, and hen behaviour were assessed throughout the trials (Trial One 20–30 weeks; Trial Two 19–28 weeks). Data were analysed using Proc Mixed of SAS 9.4 and differences were significant when P ≤ 0.05. Silage-fed hens consumed 41 (13.9 g DM) and 50 (13.5 g DM) grams of silage per hen per day in Trials One and Two, respectively, while consuming less layer diet. Birds fed silage spent less time expressing aggressive and feather-pecking behaviours and in nest boxes, and more time feeding than control birds. Egg production, egg quality, and bird weight were not affected by treatment; yolk colour was darker for the silage treatment. Feathering quality was improved in silage-fed birds compared to control birds. It was concluded that providing hens with access to barley silage can improve welfare indicators without negatively affecting the egg production and egg quality.

This study was designed to determine the effects of deep litter floor and battery cages housing system on layer feed consumption and egg production rate. Thirty two commercial hybrid layers (hyline) of 10 months production age were randomly selected and distributed equally in four deep litter ground cages, and thirty (hyline) layers were kept in battery cages, which consisted of triple deck cages, provided with automatic nipple watering system and front trough feeders. During the experimental period there were slight changes in live body weight, it was about -0.01 kg in deep litter and about 0.04 kg in battery cages system. Layers housed in deep litter system significantly consumed more feed compared to that kept in battery cages except at first week, and best averages of feed conversion ratios were calculated for layers housed in deep litter than that kept in battery cages, differences were significant for second, third, fourth and fifth weeks of experimental period. Egg production rate were significantly different in layers housed in deep litter system through the production period except the first weeks.

Betaine Supplementation

Abstract This study investigated the effect of dietary betaine supplementation and floor space on quail egg production parameters. With six replicates, four hundred fifty-six quails (21-day-old) were randomly assigned to a 2×2 factorial arrangement. The first factor was floor space of 225 cm2 (F1) and 164 cm2 (F2) by allocating 16 and 22 birds per cage (size: 3600 cm2). The second factor was dietary betaine supplementation at 0% (CON) and 0.15% (BET). Egg production was collected in 2 periods (2×28 days) starting from 43 days old. The age of the first production, 10%, 50%, and peak production, was also recorded. There is an interaction between dietary betaine supplementation and floor space on the age of productive parameters, where quails receiving betaine supplementation reached faster 50% production and peak production (p<0.05). Furthermore, the F1 group had a higher average egg production than F2 (p<0.05). BET group had a higher average egg production than CON (p<0.05). Thus, floor space 225 cm2 can be applied in the tropics provided the quails received dietary betaine supplementation.

Abstract This study investigated how combined betaine and vitamin C supplementation affects quails’ productive performance in reduced floor space. In total, 256 laying quails aged 23 weeks (154.6±5.0 g) were arranged in a completely randomized design of factorial 2×2 with four replicates. The birds were allocated to 16 cages with two floor spaces consisting of 250 cm2, 222 cm2. They were fed a diet without (Control) or with supplementation of 0.12% betaine in combination with 250 mg/kg vitamin C (BV). The collected data were analyzed by analysis of variance and continued to Duncan’s test. Interactions occurred in egg production and egg mass. The lower floor space without BV supplementation decreased egg production, but lower floor space with BV supplementation enhanced egg production (p<0.05). Supplementing BV enhanced egg mass in each floor space (p<0.05). Reducing floor space did not influence feed intake (FI), egg weight (EW), protein efficiency ratio (PER), and energy efficiency ratio (EER). BV enhances FI, egg production (EP), EW, PER, and EER and reduces the feed conversion (FCR; p<0.01). Thus, combined supplementation of betaine and vitamin C improves quails’ performance in the tropics raised with reduced floor space.

One of the problems in growing and keeping poultry, both in industrial and farm and kitchen garden environments is ectoparasites, which are responsible for lowering the productivity of poultry and causing economic losses. The study of the prevalence and diagnosis of bird ectoparasites on poultry farms with different maintenance technologies is important for the further development of integrated methods for combating them. Our research was conducted during 2006–2017 in 16 regions of Ukraine and the Autonomous Republic of Crimea. In total, 38 poultry farms specializing in egg production with poultry kept in battery cages, 18 poultry houses specializing in egg production with poultry kept on the floor and more than 150 farm and kitchen garden poultry houses for keeping chickens, turkeys, quails, guinea fowl and pigeons were examined. We found that, both with battery cages and when poultry are kept on the floor in poultry farms, the most common ectoparasites are chicken mites (Dermanyssus gallinae), which causes the disease of dermanyssiosis. It was determined that the extensivity of the invasion was, on average, from 56% to 80%. Also, in the chickens and turkeys, mallophages (Menopon gallinae, Menacanthus stramineus), which cause mallophagoses, were detected, and the extensivity of the invasion ranged from 27% to 45%. In farms and kitchen gardens where chickens, guinea fowl and quails were kept, the number of chicken mites in 1 g substrate was more than a thousand live mites, in dovecotes chicken mites were found in 50% to 100% of nests. In chickens and turkeys, besides the chicken mite, bird lice were found. In chickens, extensivity of invasion of M. gallinae, M. stramineus, Lipeurus variabilis, ranged from 15% to 22%, in turkeys, extensivity of invasion of M. gallinae and M. stramineus ranged from 16% to 25%. The scaly leg mite (Knemidocoptes mutans), which causes the disease knemidocoptiasis ("lame leg"), was detected in incubating hens over the age of two years, the extensivity of the invasion ranged from 5% to 7%. It was established that in poultry farms, both in battery cages and when the birds were kept on the floor, the main ectoparasite in chickens, guinea fowl and quail is red chicken mite (D. gallinae), and on poultry farms and kitchen gardens in addition to the chicken mite, three types of bird lice (M. gallinae, M. stramineus, L. variabilis) and K. mutans were found.
