This study aimed to elucidate the reproductive performance of purebred Holstein (HO) cows with their crosses with Fleckvieh (FV) and Brown Swiss (BS) cows under subtropical conditions. A total of 677 cows [487 HO, 104 HO × FV (HFV); 50% FV and 50% HO and 86 HO × BS (HB); 50% BS and 50% HO] were enrolled in this study. Pure HO cows had significantly greater service per conception (S/C; 3.69), days open (147.9 days), and calving interval (449.6 days), than the HFV (2.89, 116.7, and 407.4 days, respectively) and HB (3.07, 134.3, and 434.2 days, respectively) crossbred cows. At day 28, the conception percentage was significantly greater among HFV crossbred cows vs. pure HO cows [crude odds ratios (COR) = 2.16], but embryonic loss, abortion percentage, calving difficulty, and retained placenta percentage were similar (p > 0.05) among pure HO cows and their crosses. HFV crossbreds had significantly lower incidence of endometritis (COR = 0.70, p = 0.035), mastitis (COR = 0.69, p = 0.015), and ketosis (COR = 0.53, p = 0.004) vs. other cows. HB and pure HO cows had a similar incidence of mastitis, lameness, and ketosis (COR = 0.76, 0.75, and 0.81; p = 0.223, 0.468, and 0.492, respectively). HFV crossbred cows had a lower risk of culling rate than HB crossbred cows. In summary, HFV cows demonstrated the best reproductive performance in terms of S/C, days open, calving interval, conception at 28 days, mastitis percentage, ketosis percentage, and endometritis.

The objective of present study was to estimate genetic correlations between calving difficulty and productive and reproductive traits in Iranian Holsteins. Calving records from the Animal Breeding Center of Iran, collected from 1991 to 2011 and comprising 183 203 first-calving events of Holstein cows from 1470 herds were included in the dataset. Threshold animal models included direct genetic effect (Model 1) or direct and maternal genetic effects with covariance between them (Model 2) were fitted for the genetic analysis of calving difficulty. Also, linear animal models including direct genetic effect were fitted for the genetic analysis of productive and reproductive performance traits. A set of linear-threshold bivariate models was used for obtaining genetic correlation between calving difficulty and other traits. All analyses were implemented by Bayesian approach via Gibbs sampling methodology. A single Gibbs sampling chain with 300 000 rounds was generated by the TM program. Posterior mean estimates of direct heritabilities for calving difficulty were 0.056 and 0.066, obtained from different models. Also, posterior mean estimate of maternal heritability for this trait was 0.018. Estimate of correlation between direct and maternal genetic effects for calving difficulty was negative (–0.44). Posterior mean estimates of direct heritabilities for milk yield, fat yield, protein yield, days from calving to first service, days open and first calving interval were 0.257, 0.188, 0.235, 0.034, 0.042 and 0.050 respectively. The posterior means of direct genetic correlation between calving difficulty and milk yield, fat yield, protein yield, days from calving to first service, days open and first calving interval were low and equal to –0.135, 0.030, –0.067, –0.010, –0.075 and –0.074 respectively. The results of the current study indicated that exploitable genetic variation in calving difficulty, productive and reproductive traits could be applied in designing future genetic selection plans for Iranian Holsteins.

Abstract. The aim of the study was to compare the body weight and the parameters of reproductive performance in beef cows of various breeds following their import to Poland from 1995–1997. The analyses included cows of five beef breeds: Red Angus, Salers, Hereford, Limousin and Simmental. We have compared the body weights and calving intervals during the period from their arrival to Poland in 1995 until 2002, with subsequent calvings included in the analyses. Other aspects included calving difficulty, abortions, stillbirths and twin births. The analysis of the cows’ reproductive performance has revealed that the studied breeds differ in the calving interval. Best results were achieved by Simmental and Limousine cows, while Red Angus cows exhibited the poorest performance. The effect of subsequent calving on the calving interval was also confirmed. We have observed no differences among the mature cows with respect to the body weight and calving ease.

The Relationship

Abstract Etawa crossbreed (PE) goat farm has been well developed in Kokap, Kulonprogo, and Yogyakarta. The important aspects that support it are doe’s health and reproductive performance. This study aimed to determine the relationship between subclinical mastitis incidence and reproductive performance of the does. This study used 84 does from four different farms, which tested using California Mastitis Test (CMT) to determine the mastitis status. The reproductive performance data gained through a questionnaire and the relation to the mastitis status was analyzed using Chi-square. The result showed that the prevalence of subclinical mastitis was 16.67 % (14 does). In the non-mastitis does, 75.71% had long calving interval (CI), 88.57% had long days open (DO), 44.29% had Litter size (LS) 1, and 12.86% had service per conception (S/C) more than 2. Meanwhile, in the mastitis group, the does with long CI was 71.43%, long DO was 85.71%, LS 1 was 28.57%, and S/C > 2 was 14.29%. The chi-square analyses showed no relationship between subclinical mastitis cases with long CI (X2=0.22), long DO (X2=0.09), LS 1 (X2=1.19), and high S/C (X2=0.02). It can be concluded that there was no relation of mastitis cases to reproductive performance of PE does in Kokap, Kuloprogo, and Yogyakarta.

The aim of the present work was to study the effect of either gonadotrophin-releasing hormone (GnRH)–prostaglandin PGF2α–GnRH (G–P–G) or equine chorionic gonadotrophin (eCG)–PGF2α–GnRH (eCG–P–G) regimes with or without intramuscular injection of ergometrine maleate (Methergin) within 24 h post partum on the uterine involution, initiation of post partum cyclicity and subsequent reproductive performance of buffalo. A total of 60 parturient Egyptian buffalos (2–4 lactations) were used to conduct this study. The involved animals were allotted into two main groups (A and B), each with 30 animals, on the basis of whether buffalo cows received an i.m. injection of 3 mg of Methergin within the first 24 h post partum (A, Meth. T) or not (B, Meth. NT). Each main group was subdivided into three subgroups: A1, A2 and A3 in case of A and B1, B2 and B3 in case of B. The G–P–G regime was applied on both A1 (Meth. T) and B1 (Meth. NT) buffalos, where each individual received two i.m. injections of 0.020 mg GnRH analogue (buserelin) at Days 18 and 33 post partum with i.m. injection of 25 mg PGF2α (Dinoprost) in between at Day 25. The eCG–P–G regime was applied on both A2 (Meth. T) and B2 (Meth. NT) buffalos, where each individual received i.m. injection of 1000 IU eCG, 25 mg of PGF2α (Dinoprost) and 0.020 mg of GnRH analogue (buserelin) at Days 8, 18 and 25 post partum, respectively. The A3 subgroup (Meth. T, alone) was control for A1 and A2 subgroups and the B3 subgroup was the non-treated control for all subgroups. There was a significant (P < 0.01) decrease in the days required for complete uterine involution in subgroups A1, B1 and A3, indicating the enhancement of uterine involution. The post partum cyclicity was initiated earlier in all of the treatment regimes applied in the present study, as was indicated by significant (P < 0.01) decrease in the days to first ovulation in these subgroups compared with the non-treated control subgroup. The reproductive performance of treated buffalos improved as was shown by the significant (P < 0.01) decrease in days to first service, days open and calving interval. It is concluded that enhancement of uterine involution and/or earlier initiation of post-partum cyclicity improve the reproductive performance of buffalos.
