The gazelles obtained from the 75th Year Gazelle Production Station were placed in individual crates of 100x36x90 cm made of plywood, with 51 numbers (24 females, 27 males) gazelles in 2020 and 40 numbers (19 females and 21 males) in 2021. Mass releases were made with a ceremony in an area with similar climatic characteristics, which is approximately 380 km away. 1 gazelle died in 2020, 6 gazelles died in 2021. During the post-release monitoring activities, the first reproduction records of gazelles released in 2020 were successfully recorded in 2021 and 23 new individuals were obtained. The current number of individuals reached 106. It has been observed that gazelles have adapted to the area in the 2 years. Illegal hunting is prevented as the region is within the borders of military security. Monitoring studies continue for the long-term management plan.

It was observed that physiological responses of broiler chickens to in-house stressors increased with age. The effects of age and sex on feather coverage of abdomen (P<001 and P<0.006) and chest of broiler (P<0.002 and P<0.001) were found to be significant. It was found that the birds in both sex groups had a significantly dirty feather with age (P<0.001) and the food pad quality of birds in both sex groups had worsened with age (P<0.001). As expected, male broilers gained significantly more body weight (P<0.001) and consumed less feed (P<0.001). Age and sex interactions for all data obtained in this study were not to be found significant. As conclusion we can say that age and sex may be important signs of welfare risks in broiler chickens. More emphasis and attention on the care and management of the male birds should be given to control the house internal conditions and flock monitoring.

Depending on the amount of these vegetables consumed, both positive and negative metabolic effects from glucosinolate metabolites may occur. The aim of this study was to investigate inexpensive animal food sources that both increase weight gain and provide enhanced performance parameters without adversely affecting the animal’s health and metabolism; to evaluate dose adjustment of food containing glucosinolates in animals; and to evaluate changes in the biochemical and performance status of chickens on the glucosinolate containing diets. Day-old Ross 308 broiler line chicks (624) were divided into 1 control and 3 treatment groups. Cress seed (Lepidium sativum) was added 0.05% for the first treatment group (group 1, 10g/kg), 0.10% for the second treatment group (group 2, 20g/kg) and 0.15% for the last treatment groups (group 3, 30 g/kg) to...

Propylene glycol (PG) is a precursor of ruminal propionate for gluconeogenesis used to increase metabolic adaptation to the early postpartum period. The aim of this study was to determine the effects of daily drenching of PG during the fixed‐time artificial insemination (FTAI) protocol on beta‐hydroxybutyric acid (BHBA), glucose, adiponectin, insulin‐like growth factor‐1 (IGF1) concentrations, follicle size and pregnancy rate in dairy cows. Cows (n = 148) were randomly divided into two groups and received either 300 mL of PG (PG‐OVS, n = 76) or 300 mL of water (CON‐OVS, n = 72) each day of the Ovsynch protocol (GnRH‐7 days‐PGF2α‐56 hours‐GnRH‐16‐18‐hour FTAI) between days 57 ± 3 to 67 ± 3 postpartum for the first service. Body condition scores (14 days before expected calving, at calving, on days 21 and 42 postpartum) were...

The scientific data showing the effects on animal health are important as well as the studies related to the economic performance of milking robots. The aim of this study was to evaluate the hoof diseases encountered on dairy cattle farms working with robotic milking system and to determine the causes and to provide the necessary precautions to prevent and control hoof health problems. In the study, 93 Holstein dairy cattle aged between 35-54 months were evaluated in a dairy farm with two robotic milking system (system capacity of 120 cows/day). The locomotion scores were recorded and the cows' feet were examined in hoof trimming chute and claws of all cows were trimmed according to biomechanical characteristics of foot. The treatment method was determined according to the condition of the lesion in cases of hoof disease and the results of recovery were followed. In the herd, cases of claw deformation (6.4%; n=6), sole ulcer (4.3%; n=4), white line disease (3.2%; n=3), digital dermatitis (8.6%; n=8), heel lesion (6.4%; n=6), foot rot (1.0%; n=1), limax (2.1%; n=2), hoof crack (2.1%; n=2) and coroner inflammation (1.0%; n=1) were recorded. Evaluated etiologically, it has been found that mistakes in the application of bath solutions used in the single footbath at the exit of the robotic milking unit in the formation of infectious foot diseases, feeding mistakes made without regard to cow traffic in the case of non infectious foot diseases and exposure of the foot to traumas due to not paying attention to comfort in the feeding areas are effective. As a result, to prevent management malfunctions causing metabolic problems, stress and traumas in animal, the use of senseless technology should be avoided in order to ensure sustainable hoof health on robotic milking farms.

The effect of exogenous amylase supplementation on lactation diets with low starch concentration (19.5% of dry matter) and dry period diets with moderate starch concentration (15.5% of dry matter) was evaluated. A total of 30 multiparus Holstein cows were randomly assigned to two groups fed diets with (n=15) or without amylase (n=15). Treatments were granular amylase (0.5 g of Ronozyme RumiStar per kg of total mixed ration dry matter) or control. The research was conducted starting at 21 d prepartum until 84 d postpartum. Starch and neutral detergent fiber concentrations averaged 15.5±0.5% and 15.7±0.9%, 42.6±1.1% and 43.4±1.2% in close up diets and 19.8±2.9% and 19.4±0.5%, 33.6±0.8% and 34.2±0.6% in lactation diets for control and amylase, respectively. Dry matter intake, milk yield and composition were evaluated for differences between treatments. Postpartum intakes of dry matter (DMI) and organic matter (OM), neutral detergent fiber (NDF), crude protein (CP), and starch intake were unaffected by treatment. Milk yield was not influenced by treatment, but numerically greater by 2.0 kg/d for cows fed amylase compared with control diet. The percentages of milk fat, protein and lactose were not impressed by treatment, however fat-, solid-, and energy-corrected milk were 2 kg/d greater for cows fed amylase diet than for cows fed control diet. Fat-, solid-, and energy-corrected milk feed conversions (kg/kg DMI) were 5 to 6% greater for cows fed amylase diet than for cows fed control diet (P<0.01). It was concluded that inclusion of amylase improved the feed efficiency of lactating cows fed a low starch diet, may offer for potential to increase milk yield; but the enzyme did not affect DMI.

Twenty four multipar- ous Holstein cows were sorted by parity, body condition score and dry matter intake in close-up period, average milk production of previous lactation and season of calving and assigned to one of the three groups. Each group consisted of eight cows. The cows in group 1 (G1) received two drenches at calving and 24h after calving. The cows in group 2 (G2) received three drenches at calving, 24h after calving and 7 days after calving. The cows in group 3 (G3) were the control (no drench). Each drench contained 0.68kg of calcium propionate. There were no statistical differences for serum BHBA concentrations at all times among groups (P>0.05), except for the differ- ence at calving between G1 and G3 (P<0.05). Two drenches of calcium propionate tended to decrease serum BHBA concentration and the incidence of subclinical ketosis during first 4 weeks of lactation.

Day old chicks in all kind of poultry were assessed based on length as short, middle and long by measuring the length of stretched chick from the tip of the beak to tip of the middle toe using a ruler. Then, they were weighed. There was a significant positive correlation between the day old chick length and body weight in all groups in broiler and quail chicks. The body weight and chick length uniformity in long groups in all poultry was better than the short groups. In a conclusion, measuring body length may be a useful tool to estimate growth potential rather than using hatch body weight.

The animals with retained placenta (RP) were divided into three treatment groups (TI; n=65, TII; n=47, TIII; n=30) and control group (n=80, without RP). In RP groups, 48-72 h after calving fetal membranes were manually separated. No administered in any drugs cows in TI group. All cows in T2 and T3 groups received intrauterine 2 g chlortetracycline boluses for 3 d. All cows in T3 group received systemic antibiotic treatment consisted of 10mg/ kg oxtetracycline that was administered for 4 d and cows with fewer on day 4 th received oxtetracycline for an additional 3 d. Reproductive performance data were collected until pregnancy diagnosis or at six months post-partum and documented were days of the first service, first service conception rate, days open, services per conception rate. No significantly differences were found in all groups for non-pregnant cows after 180 d after post-partum. All the reproductive parameters were obtained in treatment groups were significant differences than the control group (P<0.05). This study indicated that RP in multiparous cows resulted negative impact on the reproductive performance in all treatment groups.

Thermal images of the rear feet of 139 lactating dairy cows were taken with a thermal camera and evaluated using imaging software. Foot lesions identified in the study included white line disease (WLD), sole ulcer (SU) and digital dermatitis (DD). Temperatures at the coronary band (CBT) and the skin (ST) were recorded. Cows were scored for locomotion on a scale of 1–5 (1 = normal and 5 = severely lame). CBT was higher for all types of foot lesion (34.1 ± 2.3, 33.8 ± 1.6 and 33.1 ± 1.6°C for WLD, SU and DD, respectively) than for healthy (32.6 ± 1.9°C) feet. ST was higher only for WLD (33.2 ± 2.0°C) compared to healthy feet (31.5 ± 1.7°C). ΔT (temperature difference between CBT and ST) was higher for SU (2.1 ± 0.8°C) than healthy feet (1.1 ± 0.9°C). Locomotion scores (LSs) were similar between healthy cows (2.2 ± 0.7) and DD (2.4 ± 0.7) but greater for SU and WLD cows (3.0 ± 0.9, 3.0 ± 0.8) than healthy cows. The threshold values established for CBT and ST were 33.5°C (sensitivity = 77.8%, specificity = 65.2%) and 33.7°C (sensitivity = 44.4%, specificity = 92.9%) for SU, and 34.4oC (sensitivity = 28.1%, specificity = 88.6%) and 31.8°C (sensitivity = 60.7%, specificity = 55.4%) for overall lesion, respectively. These results indicate that IRT can be a useful tool for detection of SU, but not WLD and DD. In addition, CBT and ΔT were the best indicators for the detection of foot lesions.

A total of 684 day-old male broiler chicks were randomly assigned to 12 treatment groups based on the lighting, stocking density and litter amount with three replicates. Data on growth, welfare indicators, meat and litter quality were obtained. The birds at the greater density grew slower (P<0.001) and consumed more feed for per kg. body weight gain compared to other stocking density groups. Under the conditions of the current study mortality of broilers grown at all densities were found similar. As stocking density increased, litter moisture, litter pH and the incidence of footpad lesion were adversely affected. In general; lighting program and litter amount had no significant effect on growth, meat quality and welfare indicators of broilers. We observed no difference in H/L ratio for the tested main effects lighting program, stocking density and litter amount. Significant interactions were determined between the main factors of some of the traits investigated. The results of this study indicated that increased stocking density higher than 19 birds/m 2 adversely affected growth responses, litter quality and incidence of footpad lesions. Therefore, much attention should be given to create better growing conditions especially at higher stocking density by using high quality and more abundant litter material and applying proper managerial practices.

Then, they were weighed. There was a significant positive correlation between the day old chick length and body weight in all groups in broiler and quail chicks. The body weight and chick length uniformity in long groups in all poultry was better than the short groups. In a conclusion, measuring body length may be a useful tool to estimate growth potential rather than using hatch body weight.

The animals with retained placenta (RP) were divided into three treatment groups (TI; n=65, TII; n=47, TIII; n=30) and control group (n=80, without RP). In RP groups, 48-72 h after calving fetal membranes were manually separated. No administered in any drugs cows in TI group. All cows in T2 and T3 groups received intrauterine 2 g chlortetracycline boluses for 3 d. All cows in T3 group received systemic antibiotic treatment consisted of 10mg/ kg oxtetracycline that was administered for 4 d and cows with fewer on day 4 th received oxtetracycline for an additional 3 d. Reproductive performance data were collected until pregnancy diagnosis or at six months post-partum and documented were days of the first service, first service conception rate, days open, services per conception rate. No significantly differences were found in all groups for non-pregnant cows after 180 d after post-partum. All the reproductive parameters were obtained in treatment groups were significant differences than the control group (P<0.05). This study indicated that RP in multiparous cows resulted negative impact on the reproductive performance in all treatment groups.

Foals were classified as FTPI positive (IgG < 8 g/L) or negative (IgG ≥ 8 g/L) using the SNAP foal test. We compared the sensitivity and specificity of serum GCT and colostrum BRIX % for diagnosing FTPI in all foals and in the sub‐group of foals which developed diarrhoea within the first month of life was noted. The relationships between the results of the serum GCT and colostrum BRIX...

Thermal images of the rear feet of 139 lactating dairy cows were taken with a thermal camera and evaluated using imaging software. Foot lesions identified in the study included white line disease (WLD), sole ulcer (SU) and digital dermatitis (DD). Temperatures at the coronary band (CBT) and the skin (ST) were recorded. Cows were scored for locomotion on a scale of 1–5 (1 = normal and 5 = severely lame). CBT was higher for all types of foot lesion (34.1 ± 2.3, 33.8 ± 1.6 and 33.1 ± 1.6°C for WLD, SU and DD, respectively) than for healthy (32.6 ± 1.9°C) feet. ST was higher only for WLD (33.2 ± 2.0°C) compared to healthy feet (31.5 ± 1.7°C). ΔT (temperature difference between CBT and ST) was higher for SU (2.1 ± 0.8°C) than healthy feet (1.1 ± 0.9°C). Locomotion scores (LSs) were similar between healthy cows (2.2 ± 0.7) and DD (2.4 ± 0.7) but greater for SU and WLD cows (3.0 ± 0.9, 3.0 ± 0.8) than healthy cows. The threshold values established for CBT and ST were 33.5°C (sensitivity = 77.8%, specificity = 65.2%) and 33.7°C (sensitivity = 44.4%, specificity = 92.9%) for SU, and 34.4oC (sensitivity = 28.1%, specificity = 88.6%) and 31.8°C (sensitivity = 60.7%, specificity = 55.4%) for overall lesion, respectively. These results indicate that IRT can be a useful tool for detection of SU, but not WLD and DD. In addition, CBT and ΔT were the best indicators for the detection of foot lesions.

A total of 684 day-old male broiler chicks were randomly assigned to 12 treatment groups based on the lighting, stocking density and litter amount with three replicates. Data on growth, welfare indicators, meat and litter quality were obtained. The birds at the greater density grew slower (P<0.001) and consumed more feed for per kg. body weight gain compared to other stocking density groups. Under the conditions of the current study mortality of broilers grown at all densities were found similar. As stocking density increased, litter moisture, litter pH and the incidence of footpad lesion were adversely affected. In general; lighting program and litter amount had no significant effect on growth, meat quality and welfare indicators of broilers. We observed no difference in H/L ratio for the tested main effects lighting program, stocking density and litter amount. Significant interactions were determined between the main factors of some of the traits investigated. The results of this study indicated that increased stocking density higher than 19 birds/m 2 adversely affected growth responses, litter quality and incidence of footpad lesions. Therefore, much attention should be given to create better growing conditions especially at higher stocking density by using high quality and more abundant litter material and applying proper managerial practices.
