Reproductive traits and health status in dairy cows are largely affected by diet quality. Natural zeolite has been successfully used in livestock production as a feed supplement for some types and categories of domestic animals. This experiment was conducted over a period of 15 months involving Domestic Spotted dairy cows. The test animals were assigned to three groups, each receiving different levels of supplemental zeolite. The control group comprised cows that received no zeolite supplement. Experimental groups I and II were fed rations supplemented with 4% and 2% zeolite, respectively. The reproductive traits studied included gestation length, length of service period, length of calving interval, calf body weight at birth and calf body weight at 90 days of age. The results obtained suggest that zeolite supplementation affects some reproductive traits, depending on the zeolite level present in livestock feed.

Milk yield and milk chemical composition are largely affected by diet quality. Natural zeolite has been successfully used in livestock production as a feed supplement for some types and categories of domestic animals. This experiment was conducted over a period of 15 months involving Domestic Spotted dairy cattle. The test animals were assigned to three groups, each receiving different levels of supplemental zeolite. The control group comprised cows that received no zeolite supplement. Experimental groups I and II were fed compound feeds supplemented with 4% and 2% zeolite, respectively. The production traits studied included the following milk performance traits: whole lactation length, milk and fat yields over whole lactations, milk and fat yields over standard lactations. The results obtained suggest that zeolite supplementation affects some production traits, depending on the zeolite level present in livestock feed.

This study was carried out to determine of effect of supplemental feeding during the late gestation on birth and other weights of lambs from Akkaraman sheep breed raised in Kırşehir. Data were collected from 554 Akkaraman lambs from 580 Akkaraman sheep which were born during 2015 birth season. Akkaraman sheep were divided into two groups. Wheat straw is given to both groups during pregnancy. Supplemental feeding group group (EYG), was given to concentrated feed supplement (400 g/animal) in addition to wheat straw during the last gestation period. Control group (KG) was given only wheat straw during pregnancy. In this study, the live weights, survival rates of the lambs in various periods and reproductive traits of Akkaraman ewes were investigated. The averages of reproductive traits of Akkarman sheep such as sterility, fertility, twins, abortion, fecundity and litter size in EYG and KG groups were %12, %9, %86, %91, %13, %5, %2, %0, 0.96, 0.95 and 1.12, 1.04, respectively. The survival rates of lambs on 90th days and 150th days in EYG and KG groups were determined as 84, 80% and 91, 91%, respectively. The means of the birth, 90 and 150. days age live weights in EYG and KG groups were found as 5.82±0.06 kg, 30.94±0.44 kg, 34.47±0.44 kg and 3.43±0.04 kg, 30.17±0.04 kg, 30.96±0.38 kg respectively. The effects of supplemental feeding, sex and birth type were found to be significant on the 120. days age on birth and live weights of sheep. The effects of birth type were found to be significant on the 90. days age live weights of sheep. As a result, supplemental feeding during the late gestation are increased live weights.

Abstract The paper presents the results of the scientific and economic experiment for the evaluation of the influence of the energy supplement included in the diet of lactating cows of the Brown Swiss breed. During the research period, all animals were kept in the same conditions, corresponding to zootechnical standards. They were divided into two groups differentiated only by the feed ration. The cows of the first (control) group were given rations typical for the farm corresponding to the feeding norms of dry and lactating cows. For the cows of the second group in the dry period (14 days before calving) the feeding ration was changed with a change in structure towards an increase in the proportion of concentrated feed, and immediately after calving, they received an energy feed supplement to maintain the physiological status of dairy cows after calving. Only clinically healthy animals participated in the experiment. It was revealed that the inclusion of the energy feed supplement in the diet of lactating cows in the experimental groups during lactation led to an increase in the productivity of livestock as compared with those in the control group.

This study is designed to evaluate the effect of using parsley seeds (PAS) at different levels as a natural on semen quality and reduce the effect of lipidperoxidation of bucks. Forty New Zealand rabbit bucks 8 month old were divided into four groups (each 10 rabbit bucks). The groups were divided as follows: Control diet (free from PAS), T1: Control diet + 5g/kg PAS, T2: Control diet + 10g/kg PAS; T3: Control diet + 15g/kg PAS. Semen sample were collected twice a week; from each rabbit buck by artificial vagina. The first semen collection was used to evaluate semen quality parameters. However, the second semen collection was used for analysis semen plasma. Results revealed that feeding diets containing different levels of PAS significantly (P<0.05) increased semen volume, mass activity, individual motility, PSV, sperm concentration, total sperm and seminal plasma activity of ALP enzyme and significant (P<0.05) decrease in dead sperm and seminal plasma concentrations of total lipids, triglycerides, cholesterol and MDA and seminal plasma activities of AST and ALT enzymes and TAC as compared with the control group. In conclusion, dietary supplementation with different levels of PAS, especially at the level of 15 g/kg (T3) resulted in significant improvement in semen quality, antioxidant status and reproductive traits of rabbit bucks.

AbstractOverall reproductive performance and associated periparturient disorders were monitored in a herd of British Friesian cross dairy cows from September 1987 to August 1988. Pregnancy diagnosis and cyclical status of the herd was determined by palpation of the ovaries per rectum. A total of 49 (110) cows were randomly treated with Sepia 200c either on day 14(19) or 21 days (30) postpartum.Statistical analysis of the results was based on the differences between the control and combined Sepia-treated groups. Although there were significant differences in the proportion of heifers calving in each group, there was no significant difference in periparturient disorders or during the pre-service period.However, in the Sepia Group that held a lower proportion of heifers, a significant difference was found in the conception rate to 1st service (47%), the percentage of cows in calf (90%) and total culling rate (10%) compared to the Control Group (26%, 72% and 28% respectively). A reduction (non significant) was found between the Sepia and Control services to conception (0.2), calving to conception interval (5 days) and calving index (2 days).The results of this pilot study appear to demonstrate a difference in effect between the Sepia-treated Group and Control Group. The study has been extended to treat a larger number of dairy cows to examine the reproducibility of these results.

The examination was made on the effect of systematic factors (parturition group, calving season, birth type, calf gender, and birth type-calf gender interaction) and age at first conception on the expression of reproductive traits (gestation length, service period, fertility intensity and calf birth weight) in 143 Simmental cows. The overall mean (?) for gestation length, service period, intercalving period and calf birth weight was 284.14 days, 153.82 days, 416.92 days and 35.40 kg, respectively. The parturition group effect on all fertility traits was highly significant (P<0.01). The calving season statistically significantly (P<0.05) affected the intercalving period and calf birth weight. Birth type induced very significantly longer gestation (P<0.01) and higher calf birth weight in singles (P<0.01) and significantly longer service period in twins (P<0.05). Calf gender had a very significant effect (P<0.01) only on calf birth weight, and the interaction between birth type and calf gender significantly affected gestation duration only (P<0.05). The regression effect of age at first conception on all fertility traits was not significant (P>0.05).

The present study was carried out from selected areas at Rajshahi district to evaluate the reproductive performance of dairy cows in relation to breed/genotype, age, parity, body weight and body condition. A total of 500 cows selected and data were collected directly from the dairy farms owner by using pre-tested questionnaires during the period from September 2013 to December 2014. The average reproductive performance (RP) were recorded as age at puberty (AP) 26.42±0.22 m, age at first calving (AFC) 35.48±0.22 m, post-partum heat period (PPHP) 121.85±3.48 days, service per conception (S/C) 1.93±0.04, days open (DO) 136.80±3.57 days and calving interval (CI) 401.04±3.94 days. Genotype had significant effect (P<0.05) on all the reproductive traits except on S/C. Local (L) × Holstein Friesian (HF) genotype showed earlier AP and AFC than L× Sahiwal (SL) and L. Age group had significant (P<0.05) effect on AP, AFC and other parameters were not significant (P>0.05). Middle age groups of cows had shown better RP than others groups. Parities of cows had significant effect (P<0.05) on PPHP, S/C, DO except on AP, AFC and CI. Third parity had better RP than others. The best RP was found in >300 kg BW groups. Body condition score had significant effect (P<0.05) on all RP. Good body condition score (BCS) had excellent RP. Res. Agric., Livest. Fish.7(3): 481-495,  December 2020

Milk yield, milk ingredients, health and other, production-related parameters of subclinically infected, Mycobacterium avium ssp. paratuberculosis (MAP-) shedding (positive faecal PCR, n = 20) and non-shedding (negative faecal PCR, n = 10) dairy cows were compared in the period from 10 days prepartum to 120 days postpartum. Body condition, rumen fill and faeces scores were lower in the MAP-shedding cows. There was no significant difference in plasma or urine metabolic parameters between the groups. Milk yield and lactose content tended to be lower (P = 0.074 and 0.077, respectively), somatic cell count tended to be higher (P = 0.097), while milk fat content was significantly higher (P = 0.006) in MAP-shedding cows than in the controls. Milk protein content did not differ between the groups. All other health and production parameters [number of reproductive tract treatments, number of udder treatments, number of artificial inseminations (AIs), calving interval, and service period] were significantly better in the control group. It is concluded that MAP infection, even in a subclinical form, has a significant impact on some production and health parameters of dairy cows.

The experiment was conducted with forty four pre-pubertal stages female lambs of 12.5±2.5 kg average live weight and 7.5±0.5 months of average age. Animals were equally and randomly allocated into two feeding groups, intensive and semi-intensive feeding systems with 22 animals in each group. Under intensive system, animals were fed concentrate mixture (15.0% crude protein (CP); 11 MJ metabolizable energy (ME)/kg dry matter (DM)) at the rate of 1.5% of live weight with ad libitum green grass from May to November and supplied urea molasses straw (UMS) in place of green grass from December to April. There were no significant differences (p > 0.05) in service per conception, litter size, lambing interval, gestation length, service period, birth weight and weaning weight between intensive and semi-intensive feeding system. Reproductive traits and productive traits were not affected by feeding system. Conception rate was higher (98.0%) in semi-intensive system than intensive system (83.0%). On the other hand lamb survivability was higher in intensive system than in semi-intensive system. The semi-intensive feeding system is found to be better to rear sheep for commercial purpose compared to intensive feeding system.

This research was aimed at estimating the effect of oral supplementation of Tamoxifen on productive efficiency, carcass characteristics, hormonal profile and gonadal structure of two broiler breeds. One hundred and eighty chicks of each breed of Avian48 and Arbor Acres were divided into three groups: control group; TAM10 group, supplied with 10 mg Tamoxifen/kg of body weight at 3, 5, 7 and 9 days of life; and TAM20 group, supplied at the same intervals with 20 mg Tamoxifen/kg of body weight. Both levels of Tamoxifen improved productive performance at early ages, but Arbor Acres produced better results with TAM20 levels than TAM10, while Avian48 breeds reacted adversely. On the contrary, Tamoxifen supplementation significantly decreased feed intake and feed conversion (after the first two weeks of life) compared to control with a higher level of decrease reported for TAM20 treatments than TAM10 and for Arbor Acres compared to Avian48 breed. Carcass traits were not affected significantly with Tamoxifen supplementation compared to control although Arbor Acres responded better to TAM20 and Avian48 for TAM10. With regard to the effect of Tamoxifen (TAM) on sex hormones, it could be concluded that TAM10 treatments showed a stimulating effect on the level of such hormones as compared with the TAM20 group with the most favourable results being clearly detectable in 42-day-old birds although both concentrations of Tamoxifen did not differ significantly from control. However, treatment of broiler chickens with Tamoxifen in different doses caused a gradual decrease in follicle production rate and eventually led to an increase of the atretic follicles in different stages of atresia. Finally, we can conclude that Tamoxifen supplementation can improve performance and carcass efficiency of broilers without changing the hormonal profile, however much research is required to estimate the best concentration required for each breed.
